If f(x) = -x^2+4x-9 and g(x) = x - 8 find g(f(-1)).

satela [25.4K]

Answer: g(f(-1))=-22

Step-by-step explanation:

To find g(f(-1)), you want to first want to solve f(-1). Once you solved that, you plig the answer you get into g(x). Then, you will have your final answer.

f(-1)=-(-1)²+4(-1)-9 [exponent]

f(-1)=-1+4(-1)-9 [multiply]

f(-1)=-1-4-9 [subtract from left to right]

f(-1)=-14

We have found that f(-1)=-14. Now, we know in -14 into g(x) and solve.

g(-14)=(-14)-8 [subtract]

g(-14)=-22

Now, we know that g(f(-1))=-22.

Simplify 4 to the 7th over 5 squared all raised to the 3rd power

alisha [4.7K]

<h2>Answer:</h2>

$\left(\frac{4^{21}}{5^6}\right)$

4 to the 21st over 5 to the 6th.

<h2>Step-by-step explanation:</h2>

First, we need to write our expression. Let's do it step by step:

$4^7$

<u>5 squared:</u>

$5^2$

<u>4 to the 7th over 5 squared:</u>

$\frac{4^7}{5^2}$

<u>4 to the 7th over 5 squared all raised to the 3rd power:</u>

<u> $\left(\frac{4^7}{5^2}\right)^3$ </u>

Using the law of exponents:

$\left(\frac{4^{7\times 3}}{5^{2\times 3}}\right) \\ \\ \left(\frac{4^{21}}{5^6}\right)$

Finally, the answer is 4 to the 21st over 5 to the 6th.

What is the best approximation for the area of this circle?

butalik [34]

$Area =113.0ft^2$ . Correct option is D) 113.0 ft² .

<u>Step-by-step explanation:</u>

Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:

We know that area of circle = $\pi r^2$ , We have following parameters as

$Radius = r = 6 ft\\\pi = 3.14\\Area= \pi r^2 = ?$

So , Area of circle is

⇒ $Area =\pi r^2$

⇒ $Area =(3.14) (6)^2$

⇒ $Area =(3.14) (36)^$

⇒ $Area =113.04ft^2$

On Rounding off

⇒ $Area =113.0ft^2$

Therefore , $Area =113.0ft^2$ . Correct option is D) 113.0 ft² .

Please put it in expanded form and solve it

Reptile [31]

Answer:

1/xyz^3

Step-by-step explanation:

exponents are subtracted when divided

x^0 is 1

negative exponents are positive in the denominator

(4x^0y^-2z^-3) / (4xy-1)

(4xy^-2z^-3) / (4xy^-1)

x-1y^-1z^-3

1/xyz^3
