If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s t)(-7)? A. -439 B. -141 C. 153 D. 443

Ulleksa [173]

Answer: Option A -439

(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
Answer: Option A -439

A house cost $120,000 when it was purchased. The value of the house increases by 10% each year. What is the rate of growth each

hammer [34]

Answer: C) 0.833%

Step-by-step explanation:

Given: Cost price of house = $120,000

The rate of increase of its cost = 10%

Therefore, the increase amount of house per year =10% of $120,000

$=\frac{10}{100}\times120000=\$12,000$

Now, the amount increase each month= $\frac{12000}{12}=\$1000$

Let r be the rate of growth each month, then

r% of $120,000=1000

$\Rightarrow\frac{r}{100}\times120000=1000\\\Rightarrow\ r\times1200=1000\\\Rightarrow\ r=\frac{1000}{1200}=0.833\%$
