Answer:

d) 63 square units

Step-by-step explanation:

x = 3 units (base - b)

y = 6 units (width - w)

h = 7 units (length and height - l and h)

  • Area of a rectangle: l*w
  • Area of a triangle: 1/2*b*h

For the triangles:

Area of a triangle: 1/2*b*h

A = 1/2 * 3 * 7

A = 1/2 * 21

A = 10.5

*Since there are two triangles, it would be 10.5 * 2 = 21

For the rectangle:

Area of a rectangle: l*w

A = 7 * 6

A = 42

Now, we add them together:

A = 42 + 21

A = 63 square units

Therefore, the area of the parallelogram is 63 square units

Hope this helps!

a company that manufactures bicycles has a fixed cost of $80,000. it costs $100 to produce each bicycle. the total cost for the
frez [133]

C(x) = 80000 + 100x is the total cost as function of number of cycles produced

C(90) = 89000 and it costs $ 89000 to produce 90 bicycles

<em><u>Solution:</u></em>

Given that, company that manufactures bicycles has a fixed cost of $80,000

Fixed cost = $ 80,000

Let x be the number of cycles produced

Let C(x) be the total cost as function of number of cycles produced

It costs $100 to produce each bicycle

Variable cost = 100 x number of cycles produced

variable cost = 100x

The total cost for the company is the sum of its fixed cost and variable costs

total cost = fixed cost + variable cost

C(x) = 80000 + 100x

Thus total cost as function of "x" is found

<em><u>Find and interpret C(90)</u></em>

Substitute x = 90 in C(x)

C(90) = 80000 + 100(90)

C(90) = 80000 + 9000

C(90) = 89000

Thus it costs $ 89000 to produce 90 bicycles

PLEASE ANSWER ITS DUE SO SOON
geniusboy [140]

the line is negative because it goes down as you move right

slope = rise/run = 4/2 = 2

y = 2x+b

use a point on the line - I picked (-4, 3)

3 = 2(-4)+b

3 = -8+b

11 = b

<h2>y = 2x +11</h2>
