Positive parabolas are concave, and usually open upwards or downwards if they are functions ( functions have one output for every input). However, since your equation is x=ay^2, then your parabola is set to point rightwards (note, it is not a function since for every input of x, you can have multiple outputs of y). The above image was found by typing your equation into Google search, so as to give you an idea of what I am talking about and also to check my own answer.

Find the volume and surface area of this prism.
mina [271]

Answer:

V = 408 cm cubed

SA = 558 cm squared

Step-by-step explanation:

To find the volume of a prism, multiply the area of the base by the height. This is 1/2 times width times height times length.

V =1/2 l*w*h =1/2* 6*8*17 = 408

To find the surface area of a prism, find the area of the triangular base and the area of each rectangular side.

Area of the base is A = 1/2 * b*h = 1/2 * 6 * 8 = 24. Since there are 2 bases, the area is 48.

Area of the rectangular side is A = b*h = 17*10 = 170. Since there are three, the area is 3*170 = 510.

The surface area of the prism is 48 + 510 = 558.

PLEASE I WILL GIVE BRAINLIEST..................don't do it A
Ivahew [28]

Step-by-step explanation:

b.3n/2 = 7/2

6n = 14

n = 2 1/3

c.-x/2 + 6 = -13/4

-x/2 = -37/4

-4x = -74

x = 18 1/2

d.3x/10 = 2/5

15x = 20

x = 1 1/3

e.x/10 = -20/3

3x = -200

x = -66 2/3

f.269x/56 = 10

269x = 560

x = 2 22/269
