Factor Completely: x2 + 16 (x + 4)(x - 4) (x - 4)(x - 4) (x + 4)(x + 4) Prime

1 answer:

7 0

I think the correct answer from the choices listed above is the last option.The expression x^2 + 16 is a prime expression which cannot be further simplified over the real numbers. But when considering the complex numbers, the factor would be:

(x + 4i)(x - 4i)

F(x)=3x-4 and g(x) = x2 find the value of f(3)-g(2) show all work

zheka24 [161]

Answer: 1

f(x) = 3x - 4 => f(3) = 3.3 - 4 = 9 - 4 = 5

g(x) = x² => g(2) = 2² = 4

=> f(3) - g(2) = 5 - 4 = 1

A fruit bowl is shaped like half of a sphere. The radius of the bowl is 15cm. what is the volume of the bowl

Naya [18.7K]

Answer: 7065 cm

Step-by-step explanation:

Find the volume as the bowl was a whole sphere and then divide the volume found by two, to get the volume of half the sphere.

(4/3) * π*(r^3) ≈ 14130 cm

14130/2 ≈ 7065 cm

This is an approximated result using π = 3.14

Find g^−1 (x) when g(x) = 3/5 x −9. 5/3x − 1/9 5/3 x + 9 −3/5 x+ 9 5/3 x + 15

Cerrena [4.2K]

Answer:

5/3 x + 15

Step-by-step explanation:

The inverse of a function is the reflection across the line y = x. As such, algebraically it is found by switching y and x in the equation and isolating to solve for y.

g(x) = 3/5 x - 9

x = 3/5 y - 9

x + 9 = 3/5 y

5(x+9) = 3y

(5x + 45)/3 = y

5/3x + 15 = y
