15. If a=3 and b= -2, find the values of:
(i) a^a + b^b
ii) a^b + b^a

Answers

Answer 1

Answer:

Step-by-step explanation:

(i) a^a + b^b

for a=3 and b= -2

3^3 + -2^(-2)

          -2^(-2) = -(1/2^2)

3^3  -(1/2^2)

27 - (1/4)

26 3/4

ii) a^b + b^a

a^b + b^a

for a=3 and b= -2

3^(-2) + (-2)^3

1/3^2 + (-2)(-2)(-2)

1/9 - 8

-7 8/9

Answer 2
In future just substitute the number in

Answers

Answer:

72

Step-by-step explanation:

Answer:  D. 72°

Step-by-step explanation:

Because a triangle equals 180 we take the given info in order to find x

[tex]108+x=180\\-108=-108\\x=72[/tex]

For what values of x is x2 2x = 24 true? –6 and –4 –4 and 6 4 and –6 6 and 4

Answers

The value of the x of the equation x² + 2x = 24 is negative 6 and 4, then the correct option is C.

What is a factorization?

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression equation is given below.

x² + 2x = 24

x² + 2x – 24 = 0

On factorization, we have

       x² + 2x – 24 = 0

x² + 6x – 4x – 24 = 0

       (x – 4)(x + 6) = 0

                         x = –6, 4

The value of x is –6 and 4.

The diameter of a circle is 28 inches. What is the circle's circumference

Answers

Answer: 87.92.

Step-by-step explanation: To find the circumference of a circle, you need the following equation:

2 x π x r, where π is ≈ 3.14 and r is the circle's radius.  If you are ever given the diameter instead of the radius, just cut the diameter in half.  In this case, the diameter was given, so we need to cut 28 in half, which makes 14.  Your equation should look like this:

2 x 3.14 x 14 ≈ 87.92.

Answers

The amount that will be withheld from his paycheck for income tax in all is d. $189.42.

What is the amount withheld?

The amount withheld is a credit against the income taxes the employee must pay during the year.

The amount withheld from his paycheck for income tax in all is given by;

Amount withheld = State income tax + ( State income tax× Percentage of federal income tax)

Where:

State income tax=$154.00

Percentage of federal income tax=23%

Substitute all the values in the formula

Amount withheld=$154.00+($154,00×23%)

Amount withheld=$154.00+$35.42

Amount withheld=$189.42

Hence, the amount that will be withheld from his paycheck for income tax in all is d. $189.42.

Answers

Answer:

Each angle has a measure of 75 degrees

Step-by-step explanation:

First of all, we know that angle Z has a measure of 120 degrees and that angle W is a right angle. This means that the measure of angle W would have to be 90.

Next, we know that because the shape is a quadrilateral, the sum of its interior angles has to be equal to 360. Since we know that the measure of angles X and Y are equal (by definition of congruent), we will label them both with the variable x. We can then say the following:

2x + 90 + 120 = 360

We can then proceed to simplify this:

2x + 210 = 360

2x = 150

x = 75

So, the measure of x and y are 75.
