vovangra [49]

Answer:

Lateral area of the cylinder = 62.85 cm²

Step-by-step explanation:

Given:

Diameter of cylinder = 10 cm

Radius of cylinder = 10 / 2 = 5 cm

Height of cylinder = 2 cm

Find:

Lateral area of the cylinder

Computation:

Lateral area of the cylinder = 2πrh

Lateral area of the cylinder = 2(22/7)(5)(2)

If f(x) = x2 − 2x + 9 and g(x) = 8 − x, what is (f o g)(−4)? A. 111 B. 144 C. 120 D. 129
lapo4ka [179]

Answer: OPTION D

Step-by-step explanation:

Given the functions f(x) = x^2 - 2x + 9 and  g(x) = 8 - x, you need to substitute the function g(x) into the function f(x), then:

(fog)(x)=(8-x)^2 - 2(8-x) + 9

Now, you need substitute the input value x=-4 into (fog)(x), then you get the following output value:

 (fog)(-4)=(8-(-4))^2 - 2(8-(-4)) + 9

 (fog)(x)=(8+4)^2 - 2(8+4) + 9

 (fog)(x)=(12)^2 - 2(12) + 9

 (fog)(x)=129

This matchis with the option D
