A cube has an edge of 3 feet. The edge is increasing at the rate of 2 feet per minute. Express the volume of the cube as a function of m, the number of minutes elapsed. Hint: Remember that the volume of a cube is the cube (third power) of the length of a side. V (m) = 3 feet?

Answers

The volume of the cube as a function of m, the number of minutes elapsed, is V(m) = 4m^3 + 18m^2 + 30m + 27.

The volume of a cube with an edge length of 3 feet is given by V = s^3, where s is the length of a side.

Since the edge is increasing at a rate of 2 feet per minute, the length of the side can be expressed as s = 3 + 2m, where m is the number of minutes elapsed.

Substituting this expression for s into the volume formula, we get:

V(m) = (3 + 2m)^3

Expanding this expression, we have:

V(m) = (3 + 2m)(3 + 2m)(3 + 2m)

= (9 + 6m + 6m + 4m^2)(3 + 2m)

= (9 + 12m + 4m^2)(3 + 2m)

= 27 + 18m + 12m + 8m^2 + 6m^2 + 4m^3

= 4m^3 + 18m^2 + 30m + 27

Therefore, the volume of the cube as a function of m, the number of minutes elapsed, is V(m) = 4m^3 + 18m^2 + 30m + 27.

Which inequality is represented by the graph?(20 POINTS)

Answers

Answer:

C. y<5/3x-3

Step-by-step explanation:

First, treat this problem as if you were graphing a normal slope intercept form equation, y=mx+b, where m=slope and b=the y-intercept. To find the slope of the line, find two points on the graph and count the number of units up/down over the number of units right/left. You could also use the slope formula, (y2-y1)/(x2-x1).

Once you have the slope, which, in this equation, is 5/3, find b, the y-intercept. You can find it by seeing where the line intersects with the y-axis (the vertical axis). In this case, b=(-3).

If this was a normal line, the equation would be y=5/3x-3. However, it's an inequality, and we're not quite done yet. We can eliminate answer B.

Look closely at the line. If it's dotted, the symbol is either a less-than/greater-than symbol (< or >). That means the answer can be any number up to that OR any number above that, but not that exact number. If it's a solid line, that means it's either a less-than or equal-to/greater-than or equal-to symbol, which looks like < and >. That means the answer can be that number and any number up to it OR that number and any number above it. This graph shows a dotted line, so we can eliminate answer A.

Now, one of the hardest parts, though it's really quite easy. If an equation is less-than or less-than or equal-to, the shaded region (all the possibilities) would be below the line. This is easy to tell with a horizontal line, easy enough to tell with a diagonal line, and a little difficult with a vertical line. With a vertical line, think of a number line with a single point on it. Anything to the left of the point is less than the point, so you would shade to the left of the line. If an equation is greater-than or greater-than or equal-to, the shaded region would be above the line, because it's the opposite of less-than or less-than or equal-to. Because the shaded region is below the line, the symbol to use in this equation is < because the answer is unknown but definitely below that line, but not on the line, because it's not a solid line, which means the answer is included.

The inequality of this line is y<5/3x-3, which is listed as answer C. Hope that helped! Comment if it didn't make sense.

If the density of blood is 1.060 g/ml, what is the mass of 6.56 pints of blood? [1 l = 2.113 pints]

Answers

The mass of 6.56 pints of blood is 3.92 grams.

Given

The density of blood = 1.060 g/mL and mass of 6.56 pints

We have 1L = 2.113 pints

The density of a substance can be defined as the ratio of the mass of the substance to the volume of the substance. In chemistry, density is used to measure the concentration of the substance in the solution.

The expression for density = mass/volume

ρ = m/V

m = ρV

Mass = 1.060(1000ml/1L) × 6.56(1L/ 2.113)

= 3290.8 /1000

= 3.29g

Answers

With 99% certainty, the population proportion of adults who say they have started paying bills online in the last year is between the given confidence interval's endpoints.

What is confidence interval?

We have the following confidence interval of proportions in a sample of n people surveyed with a success probability of π and a confidence level of 1 - α.

Confidence interval = \(\pi\) ± z \(\sqrt{\(\pi (1 - \pi ))/n}\)

z = 1 - α/2

Here given, According to a survey of 3102adults, 1443 have begun paying bills online in the last year.

That is, n = 3102 and x = 1443

p = x / n

  = 1443 / 3102

  = 0.465

significance level = α

= 1 - confidence

= 1 - 0.99

= 0.01

zα/2 = z0.01 / 2 = 2.58

By substituting in confidence interval formula,

The lower limit is :

0.465 - 2.58\(\sqrt{(0.465 * 0.535) / 3102}\)

= -0.01894056008

The upper limit is:

0.465 + 2.58\(\sqrt{(0.465 * 0.535) / 3102}\)

What is confidence interval?

In statistics, a confidence interval describes the likelihood that a population parameter would fall between a set of values for a given percentage of the time. Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts.

As confidence interval (C) = π ± z√[π(1-π)/n]

In the above expression, z = 1 - α/2, where α is the significance level.

Given in the question, n=3102 as the survey was conducted on 3102 adults. Also, x=1443, as 1443 people have started paying bills online in last year.

π = x/n

Substituting the values, we get,

π = 1443/3102

⇒ π = 0.465

Confidence level(α) = 1 - confidence

= 1 - 0.99

= 0.01

Since, z = 1 - α/2

⇒ z = 1 - 0.01/2

⇒ z = 1 - 0.005

⇒ z = 0.995

By substituting in confidence interval formula,

The lower limit is = 0.465 - 0.995√[(0.465*0.535)/3102]

= 0.456

The upper limit is = 0.465 + 0.995√[(0.465*0.535)/3102]

= 0.474

Solve using system of equations. Show all work

Answers

Answer:

(8, 11)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

12x + 6y = 162

2x + 10y = 126

Step 2: Simplify systems

2x + y = 27

x + 5y = 63

Step 3: Rewrite systems

2x + y = 27

x = 63 - 5y

Step 4: Solve for y

Substitute in x:                        2(63 - 5y) + y = 27Distribute 2:                            126 - 10y + y = 27Combine like terms:               126 - 9y = 27Isolate y term:                         -9y = -99Isolate y:                                  y = 11

Step 5: Solve for x

Define equation:                    x + 5y = 63Substitute in y:                       x + 5(11) = 63Multiply:                                  x + 55 = 63Isolate x:                                 x = 8

Answer:

x = 8 and y = 11

Step-by-step explanation:

solve for y

12x + 6y = 162

-12x          -12x

6y = 162 - 12x

/6             /6  

y = 27 - 2x

substitute

2x + 10(y) = 126

2x + 10(27 - 2x) = 126

2x + 270 - 20x = 126

-18x + 270 = 126

       -270    -270

-18x = -144

-18        -18

x = 8

substitute again:

y = 27 - 2(x)

y = 27 - 2(8)

y = 27 - 16

y = 11

And divide 3: x= 7

Answer:

x = 7

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

First, multiply 6 to both sides of the equation:

\(\frac{3x + 3}{6} = 4\\ (\frac{3x + 3}{6}) * 6 = (4 ) * 6\\ 3x + 3 = 4 * 6\\3x + 3 = 24\)

Next, isolate the variable, x. First, subtract 3 from both sides of the equation:

\(3x + 3 = 24\\3x + 3 (-3) = 24 (-3)\\3x = 24 - 3\\3x = 21\)

Then, divide 3 from both sides of the equation:

\(3x = 21\\\frac{3x}{3} = \frac{21}{3} \\x = \frac{21}{3} \\x = 7\)

x = 7 is your answer.

let ~a = 〈1,1,−3〉 and ~b = 〈−1,−3,1〉. find the unit vector in the opposite direction of ~a −~b.

Answers

The unit vector in the opposite direction of ~a - ~b can be found by calculating the vector ~v = -(~a - ~b) / |~a - ~b|, where ~v represents the unit vector.

To find the unit vector in the opposite direction of ~a - ~b, we first need to compute the vector ~a - ~b, which is obtained by subtracting the corresponding components of ~a and ~b:

~a - ~b = 〈1, 1, -3〉 - 〈-1, -3, 1〉 = 〈1 - (-1), 1 - (-3), -3 - 1〉 = 〈2, 4, -4〉.

Next, we calculate the magnitude (or length) of ~a - ~b, denoted as |~a - ~b|, using the formula:

|~a - ~b| = sqrt((2^2) + (4^2) + (-4^2)) = sqrt(4 + 16 + 16) = sqrt(36) = 6.

Finally, we can find the unit vector ~v in the opposite direction of ~a - ~b by dividing -(~a - ~b) by |~a - ~b|:

~v = -(~a - ~b) / |~a - ~b| = -(〈2, 4, -4〉) / 6 = 〈-2/6, -4/6, 4/6〉 = 〈-1/3, -2/3, 2/3〉.

Therefore, the unit vector in the opposite direction of ~a - ~b is 〈-1/3, -2/3, 2/3〉.

Let Z represent a standard normal random variable. P(Z>0) is equal to
0.0
0.5
0.45
0.9

Answers

A standard normal random variable (Z) has a mean of 0 and a standard deviation of 1. The probability of Z being greater than 0 is equal to the area under the normal curve to the right of 0, which is exactly half of the total area under the curve (since the curve is symmetric around the mean of 0). Therefore, P(Z>0) is equal to 0.5.


A standard normal random variable, like Z in your question, follows a standard normal distribution, which is a special type of normal distribution with a mean of 0 and a standard deviation of 1. Now, you're asked to find the probability P(Z > 0).

Since the standard normal distribution is symmetrical around the mean (0), the probability of Z being greater than 0 is equal to the probability of Z being less than 0. In other words, half of the distribution is on the right side of the mean, and the other half is on the left side.

Therefore, P(Z > 0) = 0.5, which is your answer.

What is the equation of a parabola that passes through the points (−5, −10), (−3, 2), and (2, −3)?.

Answers

The equation of the parabola is y = -x² - 2x + 5

What is a Parabola?

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k - p

The equation of the parabola is also given by the equation

y = ax² + bx + c

where a , b , and c are the three coefficients and the parabola is uniquely identified

Given data ,

The equation of the parabola with the points

A ( -5 , -10 ) , B ( -3 , 2 ) and C ( 2 , -3 )

So , from the equation of parabola ,we get

y = ax² + bx + c


Substituting the values of x and y , in the equation of point A , we get

-10 = a ( -5 )² - 5b + c

-10 = 25a - 5b + c   be equation (1)

Substituting the values of x and y , in the equation of point B , we get

2 = a ( -3 )² - 3b + c

2 = 9a - 3b + c   be equation (2)

Substituting the values of x and y , in the equation of point C , we get

-3 = a ( 2 )² + 2b + c

-3 = 4a + 2b + c   be equation (3)

By the method of brute force , we can solve the equations and derive the equation for the parabola

So , the equation for the parabola will be

y = -x² - 2x + 5

Now , substituting the values of x and y from the points , we get

For point A ( -5, -10 )

-10 = - 25 + 10 + 5

-10 = -10

Therefore , the equation is TRUE

Now , substituting the values of x and y from the points , we get

For point B ( -3, 2 )

2 = -9 + 6 + 5

2 = 2

Therefore , the equation is TRUE

Now , substituting the values of x and y from the points , we get

For point C ( 2 , -3 )

-3 = -4 - 4 + 5

-3 = -3

Therefore , the equation is TRUE

Hence , the equation of the parabola is y = -x² - 2x + 5

The distributed simplified product is \(2x\sqrt{10x}-2x\sqrt{5}\). So, option 4 is correct.

What is distributive property?

The distributive property is given by

a(b + c) = ab + ac or (a + b)c = ac + bc.

This property is used for simplifying large expressions into small ones.

The reverse order we can write as

ab + ac = a(b + c) or ac + bc = (a + b)c.

Calculation:

The given expression is \(\sqrt{5x}(\sqrt{8x^2}-2\sqrt{x})\)

On applying distributive property: a(b + c) = ab + ac

\(\sqrt{5x}(\sqrt{8x^2}-2\sqrt{x})\) = \(\sqrt{5x}(\sqrt{8x^2}) - \sqrt{5x}(2\sqrt{x})\)

Applying multiplication of surds,

(multiplication of surds: \(\sqrt{a}\times\sqrt{b}=\sqrt{ab}\))

⇒ \(x(\sqrt{5x\times8})-2(\sqrt{5x\times x})\)

⇒ \(x\sqrt{40x}-2\sqrt{5x^2}\)

⇒ \(2x\sqrt{10x}-2x\sqrt{5}\)

Therefore, the simplified product for \(\sqrt{5x}(\sqrt{8x^2}-2\sqrt{x})\) is \(2x\sqrt{10x}-2x\sqrt{5}\).

Thus, option 4 is correct.

\(y = - \frac{9}{5} x + c\)

1.2 substitute in x and y value of one of the two given point. ill use (3;-1).

\( - 1 = - \frac{9}{5} (3) + c\)

\(c = \frac{22}{5} \)

therefore equation is

\(y = - \frac{9}{5} x + \frac{22}{5} \)

2. Now sub in x value of the point you want to test and see if y value correlates.

\(y = - \frac{9}{5} (1) + \frac{22}{5} \)

\(y = \frac{13}{5} \)

The temperature at 9 a.m. is 2 degrees. The temperature rises 3 more degrees by noon. Which expression describes the temperature at noon?

Answers

Answer: 2 degrees + 3 degrees = 5 degrees

Step-by-step explanation: Though the times might be confusing, the problem itself is simple addition- if the temperature rises, or goes up, by a certain number, in this case three, you're just going to add that number to the initial number, two.

Marissa's shape is classified as a scalene and obtuse triangle, considering it's concepts presented in this problem.

How to classify the triangle?

The triangle has three sides of unequal length, as the opposite angle measures are different, hence it is classified as an scalene triangle.

(it would be equilateral if all had the same length, and isosceles if two sides have the same length).

The triangle has one angle larger than 90º, hence it is classified as an obtuse triangle.

(acute with no angles of 90º or greater, right with one angle of exactly 90º).

Answer:

Step-by-step explanation:

probability ∈[0,1]

or probability ≥0

and ≤1

so a,b,g cannot be the probability of an event.

Answer:

See Explanation

Step-by-step explanation:

The probability of an event ranges from 0 to 1.

So, the options c. 0.6, d. 0.888, e. 0 and f. 0.39 represents the probability of an event.

Probability of an event cannot be negative number or more than 1.

Hence, options a. - 1, b. 4.2, g. - 0.5 does not represent the probability of an event.
