What is the surface area of this regular pyramid?

Mathematics
1 answer:
tekilochka [14]3 years ago
4 0
Answer: option b

Step by step explanation; surface area is the value that expresses the amount of area you can touch on a figure

Since there's four triangular faces, you do 4*(1/2*8*15)

Since there's one square face, you do (8*8)

Together, you expression is (8 * 8) + 4 *(1/2 * 8 * 15)

Which is 394

Write an equation that passes through -2 and 5 and perpendicular to x=7? y=mx+b
GarryVolchara [31]

Answer:

Step-by-step explanation:

I'm going to assume you mean passes through the point (-2,5) since -2 and 5 could mean a lot of different things

To find the perpendicular line's gradient, you would know that m1*m2 = -1

In this case m1 = 7, so m2 must be -1/7

Now we substitute the gradient into the equation

y = -1/7x + b

To find b, we substitute (-2,5) into the equation above

5 = -1/7*-2+b

5 = 2/7 + b

b = 33/7

Therefore the equation of the line is

y = -1/7x+33/7
