Answer:

SA= 28 in^2

V= 14 in^3

Step-by-step explanation:

circumference= 2πr

9.4 = 2πr

r = 1.496

surface area of a ball = $4\pi r^{2}$

= $4\pi (1.496)^{2}$

=28 in^2

volume of a ball= $\frac{4}{3} \pi r^{3}$

= $\frac{4}{3} \pi (1.496)^{3}$

=14 in^3

Find (g*f)(3) <br> f(x)= |x+2|<br> g(x)= -x2

Alina [70]

Answer:

Option a. $(gof)(3) = -25$

Step-by-step explanation:

They ask us to find

(gof)(3)

To solve this problem we must introduce the function f(x) within the function g(x)

That is, we must do g(f(x)).

So, we have:

$f(x) = |x + 2|\\\\g(x) = -x^2$

Then:

$g(f(x)) = -(|x + 2|) ^ 2$

This is:

$g(f(x)) = -(x + 2) ^ 2$

Now we must do x = 3

$g(f(3)) = -(3 + 2) ^ 2$

$(gof)(3) = -25.$

The answer is: $(gof)(3) = -25.$

The number 85% is equivalent to 85/100. Pablo spelled 21 out of 25 words correctly. Is this more or less than 85%

Natali [406]

First find the percentage Pablo got on the spelling:
21/25 = 0.84
0.84 * 100 = 84 ( To convert into a percent)

Therefore Pablo scored less that 85%
