If f(x)=3x+2 and g(x) =x^2 +1 which expression is equivalent to (f•g)(x)

1 answer:

5 0

(f · g)(x) = f(x) · g(x)

f(x) = 3x + 2; g(x) = x^2 + 1

(f · g)(x) = (3x + 2)(x^2 + 1) = 3x^3 + 3x + 2x^2 + 2 = 3x^3 + 2x^2 + 3x + 2

Find the missing length for the right triangle described below. B = 21 ft, c=27 ft. Find side a. Round to the nearest whole numb

maksim [4K]

Answer:

16.97 ft

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Side B = 21 ft

Side c = 27 ft

As we know, formula for right triangle is as follows,

$a^{2} + b^{2} = c^{2}$

$a^{2} = c^{2} - b^{2}$

So, by putting the value in the formula, we get,

$a^{2} = 27^{2} - 21^{2}$

$a^{2}$ = 729 - 441

$a^{2}$ = 288

a = 16.97 ft

Hence, the length of the side for the right triangle is 16.97ft.
