Find value of x in trapezoid

Find value of x in trapezoid

Answers

Answer:

  x = 1

Step-by-step explanation:

You want to know the value of x in the trapezoid with adjacent angles (43x+2)° and 135°.

Supplementary angles

The two marked angles can be considered "consecutive interior angles" where a transversal crosses parallel lines. As such, they are supplementary.

  (43x +2)° +135° = 180°

  43x = 43 . . . . . . . . . . . . . . divide by °, subtract 137

  x = 1 . . . . . . . . . . . . . . . divide by 43

The value of x is 1.

Additional comment

Given that the figure is a trapezoid, we have to assume that the top and bottom horizontal lines are the parallel bases.

Answer:

-4-5

Step-by-step explanation:

The temp was at -4 and if it dropped that means you subtract another 5 from it which is -4-5

Answer:

The correct answer is -4 - 5.

Step-by-step explanation:

The original temperature is -4 degrees.  Then, the temperature falls by 5 degrees.  The temperature "falling" means that it is getting colder or that the temperature is getting lower.  This lets us know that we need to use subtraction.  The final answer is -4 - 5, which would give us the temperature of -9 degrees as the new temperature.

The median, mean, range and mode will be 6, 5.4, 9 and 7.

What is median?

The median is the middle number in the data set when the data set is written from least to greatest.

The median is the number in the middle when arranged in an ascending order. The numbers will be:

0, 3, 4, 6, 6, 7, 7, 7, 9.

The median is 6.

The range is the difference between the highest and lowest number which is: = 9 - 0 = 9

The mode is the number that appears most which is 7.

The mean will be the average which will be:

= (0 + 3 + 4 + 6 + 6 + 7 + 7 + 7 + 9) / 9.

The value of x in the diagrams are 14 and 99 respectively

How to determine the values

Note the following points;

Corresponding angles are equal Sum of angles at a point is equivalent to 360 degrees

From the information given in the diagram

56 degrees and 4x degrees are corresponding

Then,

4x = 56

Make 'x' the subject

x = 14

From the second image

Add the angles and equate to 360 degrees, we have;

3x + 2 + 36 + x - 74 = 360

collect like terms

4x = 360 + 36

4x = 396

What are the steps to solving this problem? (i allready know the answer, i just want to know the steps.)

What are the steps to solving this problem? (i allready know the answer, i just want to know the steps.)

Answers

Answer:

Step-by-step explanation:

The first step to solving this problem is to simplify the contents inside the brackets. Since all the terms are multiplied together, you can cancel the fraction separately between the numerator and denominator. Let's start with the x terms.

The division law of exponents states that when exponents with the same base are divided, the exponents are subtracted.

This means to simplify the x terms we have:

\(\frac{x^{-4} }{x^{3}} =x^{-4-3}=x^{-7}\)

This means the overall problem now looks like this:

\((x^{-7} \frac{2y^{7} }{3y^{2}}) ^{3}\)

Now we can repeat that with the y term:

\(\frac{y^{7} }{y^{2}} =y^{7-2}=y^{5}\)

Now our complete problem only has one fraction in the brackets which we can simplify if we wish:

\((\frac{2}{3}x^{-7}y^{5}) ^{3}\\OR\\(0.67x^{-7}y^{5}) ^{3}\\\)

Now we can finish the problem by raising every term inside the brackets to the power of 3. Raising an exponent to an exponent multiplies them together so our equation is now here:

\(\frac{2}{3}^{3} x^{-7*3}y^{5*3}\\OR\\0.67^{3} x^{-7*3}y^{5*3}\)

After multiplying and simplifying we are left with the answer:

\(\frac{8}{27}x^{-21}y^{15}\\OR\\0.3x^{-21}y^{15}\)

(1dp)

Negative exponents mean they are positive as a denominator so:

\(\frac{0.3y^{15} }{x^{21} }\)

Also works as an answer

x = 15

Step 2: Find y

All angles in a triangle add up to 180°

Answers

The negations of the given statements with the application of De Morgan's law and/or conditional law.

a) ∃x (¬P(x) ∨ ¬R(x))

De Morgan's law:

∃y ∀z(¬P(y) ∧ ¬Q(z))

b) ∃y ∀z(¬P(y) ∧ ¬Q(z))

The double negation:

∃y ¬∃z(P(y) ∨ Q(z))

c) ¬∃x (P(x) ∨ (∀z (¬R(z)) → (∀z ¬Q(z))))

The conditional law:

¬∃x (P(x) ∨ (∀z (¬R(z)) → (∀z ¬Q(z))))

Let's form the negation of the given statements and apply De Morgan's law and/or conditional law, when applicable:

a) ∀x (P(x) ∧ R(x))

The negation of this statement is:

∃x ¬(P(x) ∧ R(x))

Now let's apply De Morgan's law:

∃x (¬P(x) ∨ ¬R(x))

b) ∀y∃z(¬P(y) → Q(z))

The negation of this statement is:

∃y ¬∃z(¬P(y) → Q(z))

Using the conditional law, we can rewrite the negation as:

∃y ¬∃z(¬¬P(y) ∨ Q(z))

c) ∃x (P(x) ∨ (∀z (¬R(z) → ¬Q(z))))

The negation of this statement is:

¬∃x (P(x) ∨ (∀z (¬R(z) → ¬Q(z))))

Using the conditional law, we can rewrite the negation as:

¬∃x (P(x) ∨ (∀z (R(z) ∨ ¬Q(z))))

Applying De Morgan's law:

¬∃x (P(x) ∨ (∀z ¬(¬R(z) ∧ Q(z))))

Simplifying the double negation:

¬∃x (P(x) ∨ (∀z ¬(R(z) ∧ Q(z))))

Using De Morgan's law again:

¬∃x (P(x) ∨ (∀z (¬R(z) ∨ ¬Q(z))))

A) The polynomial with the given roots and multiplicity is; P(x) = -0.3(x - 3)²(x + 1)

B) The function after the given transformations is; g(x) = [2√(x - 5)] - 2

What is the equation of the Polynomial?

A) We are told that the polynomial is of degree 3 and as such, the general form is;

y = a(x + b)(x + c)(x + d)

We are told that it has a root multiplicity of 2 at x = 3.

Thus, (x - 3)² is a factor

We are now told that it has a root of multiplicity 1 at x = -1. Thus;

(x + 1) is a factor.

Thus, the polynomial is;

P(x) = a(x - 3)²(x + 1)

y-intercept is at y = -2.7. Thus;

P(0) = a(0 - 3)²(0 + 1) = -2.7

9a = -2.7

a = -0.3

Thus, the polynomial is; P(x) = -0.3(x - 3)²(x + 1)

2) We are given the function;

f(x) = 2√x

When we shift a function by a units up, we are adding a units to the function. Thus, shifting f(x) 2 units down is the opposite and we subtract 2 from the function to get;

f'(x) = (2√x) - 2

Now, shifting the function by 5 units right means we subtract 5 from the x value to get; g(x) = [2√(x - 5)] - 2

A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.

The given percentage are,

8%, 15%, and 20%.

Now to find the overall average increase we need to find the average percentage for three consecutive years.

overall average = sum of all the percentage/number of percentage

overall average =  8%+15%+ 20%/3

overall average =  43%/3

overall average =  14.33%
