Lin and Clare were standing in the woods near a stream, and each threw a stone up in the air at the same time so that it would land in the water. The graph represents the height of a stone t seconds after it was tossed up by Lin. The function f given by f(t)=−16(t+12)(t−1) represents the height of a stone t seconds after it was thrown by Clare. In both functions, height is measured in feet.

a. Whose stone hit the water first?
When did that happened?
second after the stone was tossed

b. Clare’s stone reached its maximum height 14 second after it was tossed. Did Clare’s stone reach a higher maximum than Lin’s stone?

c. What was the maximum height of Clare's stone?
meters

answer: 7270

step-by-step explanation:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
