The coefficient is the number that multiply the variable (the variables are the letters, a,b,c etc...)


So we have 6y

The coefficient is 6

The variable is y

Estimate the original volume of the pyramid in Fig. 15.28, given that its frustum has a 4 m by 4 m square top which is 12 m vert
puteri [66]

The volume of the pyramid is 2496 cu.m.

<h3>What is a Pyramid ?</h3>

A pyramid is a three dimensional structure which has a polygon base and  in general triangular faces which join at the top .

It is given that

A pyramid \rm frustum has a 4 m by 4 m square top

Height = 12 m

Base = 20 m

The volume of a square pyramid with a  \rm frustum is given by

V = (1/2) * ( Area of base + Area of  \rm frustum ) * height of the  \rm frustum from the base

V = 0.5 * ( 20 *20 + 4*4 ) * 12

V = 2496 cu.m

The volume of the pyramid is 2496 cu.m.

Answer:

M(x,y) = (4.8,4.4)

Step-by-step explanation:

Given

P(x_1,y_1) = (6,2)

Q(x_2,y_2) = (3,8)

m:n = PM:MQ = 3 : 2

Required

Determine the coordinates of M

To solve this, we make use of the following partition formula:

M(x,y) = (\frac{nx_2+mx_1}{n+m},\frac{ny_2+my_1}{n+m})

Substitute values for m, n, x's and y's

M(x,y) = (\frac{2*3+3*6}{2+3},\frac{2*8+3*2}{2+3})

M(x,y) = (\frac{24}{5},\frac{22}{5})

M(x,y) = (4.8,4.4)

<em>Option D is correct</em>
