Find the surface area for the following figures PLease help
Yakvenalex [24]

Answer:

RP=190

TP=136

C=1,099

Step-by-step explanation:

RECTANGULAR PRISM, the equation is A=2(wl+hl+hw)

A=5*5+7*5+7*5

A=25+35+35

A=95*2

A=190

TRIANGULAR PRISM, the equation is A=1/2bh for the top and bottom triangles and A=lw for the sides

A=1/2(6)(4)

A=1/2*24

A=12

A=7*5

A=35

A=7*6

A=42

12*2=24

35*2=70

24+70+42=136

CYLINDER, the equation is A=2πrh+2πr2

A=2*3.14(7)(18)+2*3.14(7)^2

A=6.28*126+6.28*49

A=791.28+307.72

A=1,099

Please help! I have no idea what to do. I couldn't even guess an answer.
yulyashka [42]

y - y1 = m(x - x1)

Plug in:

Slope = m = 4

Point = (x1,y1) ----> (-3,7)

y - 7 = 4(x - -3) //Solve for y

y - 7 = 4(x + 3) //Answer

y - 7 = 4x + 12

y = 4x + 12 + 7

y = 4x + 19

Answer: B

//Hope it helps

Answer:  From what you wrote the I think the ball is drop

At time 0 you are 7 meters above ground

You basically just need to solve for

1.5 =7t-4.9t^2

by rearrange the equation you get

4.9t^2-7t+1.5=0

by using Quadratic Formula

t=1.166s
