Answer:

The discount id 40%, so the function is:

d = 0.4p

p = 100 ⇒ d = 40
p = 200 ⇒ d = 80
p = 300 ⇒ d = 120
p = 400 ⇒ d = 160
p = 500 ⇒ d = 200

The graph is attached

p = $85 ⇒ d = 0.4*$85 = $34

Sale price is:

CP = p - d = $85 - $34 = $51

What is the surface area of this triangular pyramid?

lidiya [134]

48.25 in^2

Step-by-step explanation:

The formula for the surface area of a pyramid is:

$SA=B+\frac{1}{2}l(number of base sides)(b)$

B represents the area of the base, which in this case is a triangle. We will figure out the area of the base first, using the formula for the area of a triangle.

$A=\frac{1}{2}bh$

$A=.5*5*4.3$

A = 10.75

Now we can plug in 10.75 for B.

$SA=10.75+.5*5*3*5$

The cursive L will be the lateral height, which is 5. Since there are 3 sides on the base we can put that in for the number of base sides, and the base is 5.

$SA=$

48.25 in^2
