be rectangular prism and rectangular pyramid have the same volume. determine the value of x, the height of the pyramid.

Marina CMI [18]

ANSWER

$x= 9 \: in$

EXPLANATION

The volume of a rectangular prism is given by the formula,

$V = l \times b \times h$
We substitute the dimensions to obtain,

$V = 6 \times 3 \times 12 \: {in}^{3}$

The volume of the rectangular pyramid is,

$V = \frac{1}{3} \times 6 \times 12 \times x \: {in}^{3}$

Equating the two volumes gives,

$\frac{1}{3} \times 6 \times 12 \times x = 6 \times 3 \times 12$

We divide through by 6×12 to get,

$\frac{x}{3}=3$

We solve for x to obtain,

$x = 3 \times 3$

$x = 9 \: in$

If f(x)=x^2+2x-4 and g(x)=3x+1 find f(g(x))=()x^2+()x+()

barxatty [35]

Answer:

9x^2+22x-2

Step-by-step explanation:

f(g(x))=(3x+1)^2+2(3x+1)-4

=9x^2+16x+6x+2-4

=9x^2+22x-2

to find the soultion of mentioned question you have to put the value of g(x) into f(x) and then solve it like normal ...

Part of a school’s stage is shaped like a sector of a circle, as shown below. The students do not yet know the exact dimensions

Natasha2012 [34]

Answer:

68.78° or 0.6 rad

Step-by-step explanation:

<u>Use the formula:</u>

degrees/360° = L/circumference
or
radians/π = L/circumference

<u>As per given:</u>

l = 12 feet, r = 10 feet

degrees = 360°*12/(2*3.14*10) = 68.78°
radians = π rad *12/(2π*10) = 0.6 rad
