To solve for f(3)g(3):

* We know fg(x) means we need to multiply f with g replacing all x's with the x-value given

  • Replace all x's with 3
  • Solve for f(3)g(3)
  • (3(3)^{2}-5)(-2(3)+5)\\(3(9)-5)(-6+5)\\22 * -1\\-22

-22 is the answer

Hope it helps!

Answer:

C  - 22

Step-by-step explanation:

Put in '3 ' for 'x' in both of the equations....then multiply the results together

f(3)  = 3 (3)^2 - 5 = 22

g(3) =  -1

22 * -1  = -22

Please explain to me and i will give brainly
GuDViN [60]

Answer:

17

Step-by-step explanation:

Look at any 2 adjacent numbers and find the difference between them.

Starting with numbers 1 and 2, subtract the first from the second:

-7-(-15)=-7+15=8

That's a difference of 8, meaning the second number increased by 8.

Check the next numbers, 2 and 3:

1-(-7)=1+7=8

It increased by 8 again. Now that we know for sure that each term in the sequence increases by 8 over the previous one, we can find the number in the green box. Just add 8 to the number before it:

9+8=17

Hi there!

\large\boxed{a = 6 m/s^{2}}

Use the kinematic equation to solve for acceleration:

a = \frac{v_{f}-v_{i}}{t}

Where:

vf = final velocity

vi = initial velocity

t = time

Plug in the given values:

a = \frac{65-35}{5}\\\\a = 30 / 5  \\\\=6 m/s^{2}

Tom Harding is a proofreader. He is paid $0.23 for every page he proofs. What is Tom's total pay for a week in which he proofrea
natka813 [3]
Alrighty, what I was always taught was to start by writing out what you know from the question.

What I know:
-Tom is paid $0.23 for every page of proofs.
-He proofreads 1,992 pages.

In order to figure out how much money Tom has made, we need to multiply 0.23 by 1,992. Multiplying allows us to see the total amount of money made by proofreading x amount of pages - for every page he proofreads, he makes $0.23.
0.23×1992=458.16

Therefore, Tom made $458.16.

Hope this helps!

(x-6)² + (x + 5)² = 16
Phoenix [80]

Answer:

answer A   : (2 -5)

Step-by-step explanation:

the midipoint P,Q is the center A of this circle (because PQ is a diameter)

use : (x-6)²+(x+5)² = 16 you have : A(6 , -5) now  let Q(x,y) :

 (x+10)/2 = 6

    (y-5)/2 = - 5                          

x+10 = 12

y-5 = -10

so : x = 2 and y = - 5....answer A   : (2 -5)
