. The height, in metres, after the launching of a projectile, and time, t, in seconds is defined: h = −3( − 1.5)
2 + 27

I dont understnad how to do d pls help me its 3am and i stil dont understand

e) When was the projectile at a height of 24 metres?

10 glasses of juice could be made with 5 carrots, 1,500 orange juice, 2,000 papaya juice.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

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.
