If s(x) = 2 - x and f(x) = 3x, which value is equivalent to (s f) (-7)

Soloha48 [4]

Answer:

Step-by-step explanation:

the first method :

s(x) = 2 - x and f(x) = 3x

(s f) (-7) = s(-7) ×f(-7)

but : s(-7) = 2 - (-7) =2+7 = 9

f(-7) = 3(-7) = - 21

so : (s f) (-7) = (9)×(-21) = - 189

the second method :

calculate : (s f) (x) == s(x)×f(x) = (2-x) 3x = 6x - 3x²

(s f) (-7) = 6(-7) -3 (-7)² = - 42 -147 = -189

Answer:

Option D. $\$83.75$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=30\ years\\ P=\$187.45*0.10=\$18.745\\ r=0.05\\n=12$

substitute in the formula above

$A=\$18.745(1+\frac{0.05}{12})^{12*30}=\$83.75$
