Answer:
-1
Step-by-step explanation:
Tip: Remember to always start from the inside, which would be g(3), in this case.
The first step in solving this problem is to solve for g(3).
To accomplish this, you must substitute 3 for x into the given equation g(x) = x^2 - 10
- g(3) = 3^2 - 10
- g(3) = 9 - 10
- g(3) = -1
The next step is to substitute the answer of g(3), -1, for x in the given equation f(x) = 2x + 1.
Because the equation is asking for f[g(3)], it becomes f(-1) because g(3) = -1.
- f(-1) = 2(-1) + 1
- f(-1) = -2 + 1
- f(-1) = -1
Therefore, f[g(3)], or f(-1), equals -1
Answer:
52
Step-by-step explanation:
Of means multiply and is means equals
25% * W = 13
Changing to decimal form
.25W =13
Divide each side by .25
.25W/.25 = 13/.25
W =52

d. y=8x-16
Answer:
b. 8 inches wide and 25 inches long
Step-by-step explanation:
Here are the options
5 inches wide and 25 inches long
b. 8 inches wide and 25 inches long
c. 15 inches wide and 15 inches long
d 15 inches wide and 25 inches long
Area of a rectangle = length x width
10 x 20 = 200
first option
5 x 25 = 125 does not have the same area as the one lanu drew
second option
8 x 25 = 200 has the same area as the one lanu drew
third option
15 x 15 = 225 does not have the same area as the one lanu drew
fourth option
15 x 25 = 375 does not have the same area as the one lanu drew
19.625cm squared because you have to divide the diameter by 2 to get the radius.
area of circle=pi times radius times radius
=3.14 times 2.5 times 2.5
=19.625cm squared
