If f(x) = 2x2 + 2, find f(5).<br> A.) 102<br> B.) 52 <br> C.) 22 <br> D.) −1.5
rodikova [14]
We answer the question by substituting 5 to all the x's of the given function,
                             f(x) = 2x² + 2
Substituting,
                              f(5) = 2(5²) + 2 = 52
Thus, the f(5) is equal to 52. The answer is letter B.

Step-by-step explanation:

i) Let p = 0.47

ii) therefore q = 1 - 0.47 = 0.53

iii) sample size, n =25

iii) standard deviation = \sqrt{\frac{p \times q}{n} }  = \sqrt{\frac{0.47 \times 0.53}{25} } = 0.0998

Therefore the correct option is

a.) The standard deviation is 0.0998. The 10% condition is met because it

    is very likely there are more than 250 catfish in the river.

divide $17.85 by 85 to obtain 1% then multiply by 100 to obtain original price.

original price = $17.85 × \frac{100}{85} = $21
