Answer 1
9^-2 = 1/81 or 0.0123
When there is a negative in front of the exponent it makes a fraction. It is usually just 1/the number it equals if it were positive.
Answer 2

Answer:

[tex] \frac{1}{81} [/tex]

Step-by-step explanation:

express that with a positive exponent using this:

[tex] {a}^{ - n} \frac{1}{ {a}^{n} } [/tex]

so ..

[tex] {9}^{ - 2} = \frac{1}{ {9}^{2} } [/tex]

now you have to evaluate the exponent/ power

so..

[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]

why 81 ?

because the exponent of 9 is 2 so you have to multiple 9 by itself so

9x9=81

so the answer is

[tex] \frac{1}{ {81}^{} } [/tex]

sorry for the bad english hehe

f(x) = 4x + 14
g(x) = 3x2 + 5x – 6

Answers

Answer:

-18

Step-by-step explanation:

[tex]f(x) = 4x+14\\g(x) = 3x^{2} + 5x -6\\f(g(x)) = 4(3x^{2} + 5x -6)+14 \\f(g(-1)) = 4(3(-1 ^{2}) + 5(-1) -6) +14 \\\\= 4(3 - 5 - 6) + 14\\= 4 (-8) + 14\\= - 32 + 14 \\= -18[/tex]

Identify the following for the exponential function y = 5(1/4)x.

a. Growth or decay?

b. Initial value

c. Growth/decay factor

d. Growth/decay rate (as a percentage)

Answers

Answer:

A)

Decay

B)

Initial value is 5.

C)

The decay factor is 0.75.

D)

75%

Step-by-step explanation:

An exponential function is given by:

[tex]f(x)=a(r)^x[/tex]

Where a is the initial value and r is the rate.

We have the function:

[tex]y=5(1/4)^x[/tex]

So, a = 5 and r = 1/4.

A)

Remember the guidelines:

It is exponential growth if r > 1. And it is exponential decay if r < 1. (And r must be positive.)

Our rate is 1/4 or 0.25.

It is less than 1, so our function is exponential decay.

B)

The initial value is the value in front of our rate.

So, our initial value in this case is 5.

C)

The decay factor will be 1 - r, where r is our rate.

Since our rate is 0.25, our decay factor is 1 - 0.25 = 0.75.

So, we are decaying by a factor of 0.75.

D)

To convert a decimal to a percent, we move the decimal dot two places to the rght and add a percent sign.

So, 0.75 will be 75.0 % or smply 75%.

It is a 75% decay.

Multiple choice answer

Answers

Answer:

C. 9.24

Step-by-step explanation:

x is the height here, looking at the triangle.

To find x, however, we first have to find the hypotenuse. To formula for that is b (side we know)/cos(α) (angle we know). Substitute b for 6, and α for 57.

6/cos(57) would equal about 11.0647.

Now back to x. To figure that out, subtract 6² from 11.01647². Then, find the square root of that.

x = √11.01647² - 6²

x = √121.3626112609 - 36

x = √85.3626112609

x = 9.23918888544335

x ≈ 9.24, so C is the answer.
