What is the surface area of a prism whose bases each have area 16 and whose lateral surface area is 65

Answers

Formula for Surface Area of a Prism: lateral area + area of 2 ends
Lateral area = 65
Area of base = 16 (2)
SA = 65 + 16(2)
SA = 65 + 32
SA = 97

Could anyone help with math?? Will up vote, thanks!If a cone-shaped vase can hold 45 cubic centimeters of water and has a radius of 2 centimeters, what is the height of the vase? Use 3.14 for pi. Round your answer to the nearest hundredth.

7.45 centimeters
10.75 centimeters
14.33 centimeters
22.50 centimeters

Answers

Answer:

The height of the cone is 10.75 cm.

Step-by-step explanation:

Given the volume of cone = 45 cubic cm

Radius of the cone = 2 cm

Height of the cone = ?

The volume formula of cone is = $\pi r^(2) (h)/(3)$

$45= 3.14*2*2* (h)/(3)$

=> $45*3 =12.56h$

=> $135=12.56h$

h = 10.748 ≈ 10.75 cm

So, the height of the cone is 10.75 cm.

volume of a cone V = pi * r * r * h / 3
so V = 45, r = 2 therefore 45 = 3.14 * 2 * 2 * h /3 => 45 = 3.14 * 4 * h /3
=> 135 = 3.14 * 4 * h => 33.75 = 3.14 * h => 10.75 = h
height = 10.75 cm rounded to 2 decimal places

Answer:

To find the composite function (f ◦ g)(x), we need to substitute g(x) into f(x) and simplify.

Given:

f(x) = x

g(x) = -2x + 3

To find (f ◦ g)(x), we substitute g(x) into f(x):

(f ◦ g)(x) = f(g(x))

Substituting g(x) into f(x), we get:

(f ◦ g)(x) = f(-2x + 3)

Since f(x) = x, we replace f(-2x + 3) with (-2x + 3):

(f ◦ g)(x) = -2x + 3

Therefore, the composite function (f ◦ g)(x) is -2x + 3.

Rewrite this expression using the distributive property then simplify.
2/3(6x+12)

Answers

so distributive property of multiplication says
a(b+c)=(ab)+(ac)

so 2/3(6x+12)=((2/3)6x)+((2/3)12)=12/3x+24/3=4x+8=4(x+2)

2/3(6x+12)

=12/3x+24/3

=4x+8
