Step-by-step explanation:
a) The nth term of a sequence is given by 3n + 5. Write down the first four terms of the sequence.
If you plug in n = 1, then you get 3*n+5 = 3*1+5 = 3+5 = 8. So 8 is the first term.
Repeat for n = 2 and you should get 3n+5 = 3*2+5 = 6+5 = 11. Or simply add 3 to the last term 8 to get 3+8 = 11.
Repeat for n = 3 and n = 4 to get the third and fourth terms to be 14 and 17 respectively.
Answer: The first four terms are 8, 11, 14, 1710.a jar of 70 candies has the following colors: 28 orange, 7 white, 14 brown, and 21 yellow.what is the probability of randomly drawing a candy that is not brown, replacing it, and then drawing a white candy?
The probability of randomly drawing a candy that is not brown, replacing it, and then drawing a white candy is 0.08, or 8%.
There are 70 sweets in the jar, 14 of which are brown, hence the likelihood of getting a candy that is not brown on the first draw is:
(70 - 14) / 70 = 56 / 70 = 0.8 P(not brown)
The jar still has 70 candies after replacing the candy, and there are now 7 white candies. As a result, the likelihood of drawing a white candy on the second draw is:
P(white) = 0.1 / 70
Because the two drawings are independent (the first candy is replaced before the second), we can multiply the odds to get the likelihood of both events occurring:
P(not brown and white) = P(white) * P(not brown) = 0.8 * 0.1 = 0.08

Which of these statements concerning the systems development life cycle is true?A) Designing the system is the first step in the SDLC.B) No phase can occur until the previous phase is completed.C) Although each phase is presented discretely, it is never accomplished as a separate step.D) There is widespread agreement that the SDLC is composed of seven phases.
The Systems Development Life Cycle (SDLC) is a process used in the development of software and information systems. It provides a framework for managing the entire software development process, from initial planning and requirements gathering through to implementation, testing, and maintenance. There are typically several phases involved in the SDLC, each with its own unique set of activities. The correct statement is "No phase can occur until the previous phase is completed."
Of the statements provided, the true statement concerning the systems development life cycle is that "No phase can occur until the previous phase is completed." This is because each phase of the SDLC builds on the previous phase, and it is necessary to complete each phase before moving on to the next one.
For example, in the first phase of the SDLC, requirements gathering and analysis, the project team works with stakeholders to identify the project scope, goals, and objectives. Once this phase is completed, the project team can move on to the next phase of the SDLC, which is typically design. In the design phase, the team uses the requirements identified in the previous phase to create a detailed design for the system. Once the design phase is complete, the team can move on to the next phase, which is typically development.
It is important to note that although each phase of the SDLC is presented discretely, they are never accomplished as separate steps. Rather, each phase is a part of a continuous process that is revisited and refined as necessary throughout the development cycle. Furthermore, while there is no consensus on the exact number of phases in the SDLC, there is widespread agreement that the process consists of several distinct phases, each with its own set of activities and deliverables.

PLEASE HELP!! The cost for parking in the local covered parking lot is calculated by ƒ(h) = 4.5 + 1.5⌈(h - 1)⌉ where h is the number of hours you parked. What is the cost for parking in the garage for 75 minutes?
Answer:
The cost of parking in the garage for 75 minutes is 4.875.
Step-by-step explanation:
The costs of parking h hours is given by the following function:
\(f(h) = 4.5 + 1.5(h-1)\)
Cost of parking 75 minutes.
1 hour is 60 minutes. How many hours are 75 minutes?
1h - 60 min
xh - 75 min
\(60x = 75\)
\(x = \frac{75}{60}\)
\(x = 1.25\)
75 minutes is 1.25 hours. So we have to find f(1.25).
\(f(1.25) = 4.5 + 1.5*(1.25-1) = 4.875\)
The cost of parking in the garage for 75 minutes is 4.875.

Use l'Hopital's Rule more than once to rewrite the limit in its final form as lim) X-0 C. Multiply the expression by a unit fraction to obtain lim x-0 D. Use direct substitution
B. Use l'Hopital's Rule more than once to rewrite the limit in its final form as lim x → 0. The correct answer is (B). Because when evaluating the limit, differentiating the equation's numerator and denominator separately. The value of limit is 1/20.
To apply l'Hopital's Rule, we differentiate the numerator and denominator separately with respect to x. We get:
lim (e^x - sin x - 1) / (7x^3 + 10x^2)
x → 0
= lim (e^x - cos x) / (21x^2 + 20x)
x → 0
Applying l'Hopital's Rule again, we get:
= lim (e^x + sin x) / (42x + 20)
x → 0
Now, we can substitute x = 0 directly into the expression:
= (e^0 + sin 0) / (42(0) + 20)

Answer:
Graph B shows the equation 2y-10<3x properly.
Step-by-step explanation:
See the attached worksheet. Rearrange the equation into standard format oy y = mx+b. where m is the slope and b the y-intercept.
The stadard format is y < (2/3)x + 5
By picking two points on each graph, a slope is calculated. All have a slope of (3/2). The y-intercept is also identified from the graph: again, all have a y-intercept of +5. The only differences in the graphs are therefore the location of the shaded area and the presence of either a dashed or solid line.
Since the equation has the inequality "<," the points satisfying this equation should those that are shaded below the line (Graphs B and C).
And since the inequality is only "<" and not "\(\leq or \geq\)," the line should not be solid (it does not include those points actually on the line). A dashed line only appears on Graph B, which also has the correct shading.
Graph B is the correct answer.
The bottom graph is cut off, but all three graphs appear to have the same line: y < (2/3)x + 5. We can eliminate C based on the solid line, without knowing the exact slope.

s.t. x1+x2−x3≤5

∀xi≥0
The maximum value of z is 0, and the values of the decision variables are x1 = 0, x2 = 10, x3 = 0, x4 = 0.
maximize: z = c1x1 + c2x2 + ... + cnxn

a21x1 + a22x2 + ... + a2nxn ≤ b2
am1x1 + am2x2 + ... + amnxn ≤ bmxi ≥ 0 for all i
In our case,
the given LP is:maximize: z = 36x1 + 30x2 - 3x3 - 4x
subject to:
x1 + x2 - x3 ≤ 5
6x1 + 5x2 - x4 ≤ 10
xi ≥ 0 for all i
We can rewrite the constraints as follows:
x1 + x2 - x3 + x5 = 5 (adding slack variable x5)
6x1 + 5x2 - x4 + x6 = 10 (adding slack variable x6)
Now, we introduce the non-negative variables x7, x8, x9, and x10 for the four decision variables:
x1 = x7
x2 = x8
x3 = x9
x4 = x10
The objective function becomes:
z = 36x7 + 30x8 - 3x9 - 4x10
Now we have the problem in standard form as:
maximize: z = 36x7 + 30x8 - 3x9 - 4x10
subject to:
x7 + x8 - x9 + x5 = 5
6x7 + 5x8 - x10 + x6 = 10
xi ≥ 0 for all i
To apply the simplex algorithm, we initialize the simplex tableau as follows:

x6| 0 | 0 | 1 | 6 | 5 | 0 | -1 | 10 |
---------------------------------------------------------------------------
Now, we can proceed with the simplex algorithm to find the optimal solution. I'll perform the iterations step by step:
Iteration 1:
1. Choose the most negative coefficient in the 'z' row, which is -4.
2. Choose the pivot column as 'x10' (corresponding to the most negative coefficient).
3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.
Ratios: 5/0 = undefined, 10/(-4) = -2.5
4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.
5. Perform row operations to
make all other elements in the pivot column zero.
After performing these steps, we get the updated simplex tableau:
| Cj | x5 | x6 | x7 | x8 | x9 | x10 | RHS |
---------------------------------------------------------------------------
z | 0 | 0 | 0.4 | 36 | 30 | -3 | 0 | 12 |

---------------------------------------------------------------------------
x10| 0 | 0 | 0.2 | 1.2 | 1 | 0 | 1 | 2.5 |
---------------------------------------------------------------------------
Iteration 2:
1. Choose the most negative coefficient in the 'z' row, which is -3.
2. Choose the pivot column as 'x9' (corresponding to the most negative coefficient).
3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.
Ratios: 12/(-3) = -4, 5/(-0.2) = -25, 2.5/0.2 = 12.5
4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.
5. Perform row operations to make all other elements in the pivot column zero.
After performing these steps, we get the updated simplex tableau:
| Cj | x5 | x6 | x7 | x8 | x9 | x10 | RHS |
---------------------------------------------------------------------------
z | 0 | 0 | 0.8 | 34 | 30 | 0 | 4 | 0 |
---------------------------------------------------------------------------
x5| 0 | 1 | -0.4 | 0.6 | 1 | 5 | -2 | 10 |
---------------------------------------------------------------------------
x9| 0 | 0 | 1 | 6 | 5 | 0 | -5 | 12.5 |
---------------------------------------------------------------------------
Iteration 3:
No negative coefficients in the 'z' row, so the optimal solution has been reached.The optimal solution is:
z = 0
x1 = x7 = 0
x2 = x8 = 10
x3 = x9 = 0
x4 = x10 = 0
x5 = 10
x6 = 0

An ice cream shop offers two ice cream cones. The waffle cone holds 12 ounces and is 5 inches tall. The sugar cone also holds 12 ounces and is 8 inches tall. Which cone has a larger radius? Best get Brainliest! No links or files.
Therefore, the waffle cone has a shorter height and larger circumference, it has a larger radius than the sugar cone.
The radius of the waffle cone is larger than the radius of the sugar cone. This is because the waffle cone is shorter and wider, so it has a larger circumference and therefore a larger radius. The radius of a cone is calculated using the formula r = h/2π, where h is the height and π is a constant. Since the waffle cone has a shorter height and larger circumference, it has a larger radius than the sugar cone. The waffle cone has a larger radius than the sugar cone because it is shorter and wider, giving it a larger circumference. The radius of a cone is calculated using the formula r = h/2π, where h is the height and π is a constant.
