To answer 13 you have to convert the numbers there are 8 pints in a gallon so 64/8=8 so there are 8 gallons
For 14 you would do 64x9=576 and there are 12in in a foot so 576/12 so 48 ft and there are 3 feet in a yard so 48/3=16 so Devon need 16 yds of ribbon

Find f(g(3)) given: * f (x) = 2x2 – 1 g(x) = 3x h(x) = j(x) = x - 5

bezimeni [28]

Answer:

161

Step-by-step explanation:

Given the functions

f (x) = 2x^2 – 1

g(x) = 3x

we are to find f(g(3))

First look for the composite function f(g(x))

f(g(x)) = f(3x)

f(3x) = 2(3x)² - 1

f(3x) = 2*9x² - 1

f(3x) = 18x² - 1

f(g(x)) = 18x² - 1

Substitute x = 3 into the result

f(g(3)) = 18(3)² - 1

f(g(3)) = 18*9- 1

f(g(3)) = 162-1

f(g(3)) = 161

Hence f(g(3)) is 161

The answer is NOT.. C. please help .

Svetach [21]

Answer:

Option B

Step-by-step explanation:

First term of the given arithmetic sequence 'a' = -3

Common difference in each successive term 'd' = -8 - (-3)

d = -5

Explicit formula for an arithmetic sequence will be,

$A_n=a+(n-1)d$

Here, n = number of term

$A_n$ = nth term of the sequence

$A_n=(-3)+(n-1)(-5)$

For n = 23,

$A_{23}$ = -3 + (23 - 1)(-5)

= -3 - 110

= -113

Option B is the answer.
