ryaan goes skydiving and falls at a constant rate toward the ground. the equation y = -32x + 14,000 represents the situation where y is the height of ryaan in feet above the ground and x is the seconds since she jumped.

which statement describes the situation?

a. from a starting position of 14,000 feet above the ground, she is ascending at 32 feet per second.

b. from a starting position of 32 feet above the ground, she is ascending at 14,000 feet per second.

c. from a starting position of 14,000 feet above the ground, she is descending at 32 feet per second.

d. from a starting position of 32 feet above the ground, she is descending at 14,000 feet per second.

C, because

-32 x seconds since she jumped + 14000

because 14000 would be 14000 units above 0, and -32 represents the seconds she had jumped, which would basically be -32+14000, which is the same as saying 14000 - 32.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
