Answer:

a. 7.53 ft high

b. 33.46 ft distance

Step-by-step explanation:

The vertex of the quadratic is located at ...

x = -b/(2a) = -(0.9)/(2(-0.0269)) ≈ 16.7286 . . . . feet from the start

The height at that point is ...

y = (16.7286)(-0.0269·16.7286 +0.9) ≈ 7.52788 ft

The gray kangaroo can jump about 7.53 ft high.

The height is zero when ...

0 = x(-0.0269x +0.9)

x = 0

x = 0.9/0.0269 ≈ 33.4572 . . . ft

The kangaroo can jump about 33.46 feet.

15.) 0.02

16.) 0.07

17.) 6.01

18.) 3.2

19.) 0.53

20.) 1.2

Step-by-step explanation:

Simple addition with decimals. If you have a whole number like 5, with a decimal like 0.07, 5+0.07 would be 5.07. 5 would take the spot of 0 in the ones place and .07 would remain. If you have 0.10+0.8, it would be 0.9 as your answer since we make 0.8 to 0.80 or 0.10 to 0.1 and add the two together. Hope this helped!
