A triangular banner has an area of 351cm2. The length of the base is two centimeters longer than four times the height. Find the height and length of the base.

Answers

Answer:

h = 13cm and b= 54cm.

Step-by-step explanation:

We have that the area $A=351cm^2$ and the base is two centimeters longer than four times the height, that is

$b = 2+4h$

where b is the base and h the height. Now, the area is

$A=(b*h)/(2)$

$351=((2+4h)h)/(2)$

$702=2h+4h^2$

$4h^2+2h-702=0$ .

Now, we are going to use the general formula to solve quadratic ecuations:

$h=(-b\pm√(b^2-4ac))/(2a)$

where a=4, b= 2 and c= -702.

$h=(-2\pm√(2^2-4(4)(-702)))/(2*4)$

$h=(-2\pm√(4+11232))/(8)$

$h=(-2\pm106)/(8)$

$h=(-2+106)/(8)$ or $h=(-2-106)/(8)$

As we are searching for the lenght, we choose the positive result:

$h=(-2+106)/(8)=13cm$

$b=2+4h = 2+52 = 54cm$ .

A company is paying a local radio station to run its commercials. The cost for running commercials is a one-time campaign fee and also a per-second fee for the air time of each commercial. The cost can be modeled by the equation y = 250 + 100x, where x is seconds.What is the slope, and what does it represent?

250; it represents the per-second fee of air time
250; it represents the one-time campaign fee
100; it represents the one-time campaign fee
100; it represents the per-second fee of air time

Answers

250 represents the one time campaign fee because you only have to pay for it once 100 represents the cost per second

Find the volume of a triangular pyramid with a base area of 24 ft2 and a height of 18 ft.144 ft3

432 ft3

Answers

the answer to that is 144 ft ^3.

Volume = (1/3) * base area * height
= 1/3 * 24 * 18
= 144 ft^3
