Answer:
17 seconds
Step-by-step explanation:
h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..
28 = -2t² + 34t + 28
Now solve for t...
0 = -2t² + 34t (subtract 28 from both sides)
0 = t² - 17t (divide both sides by -2)
0 = t(t - 17) (factor out a t)
So
t = 0
or
t - 17 = 0
t = 17
0 seconds is the initial height. At 17 seconds, the ball will return to that height
i hope this work for you
Answer:
4:18 8:36 1:4.5
Step-by-step explanation:
The value of x from the figure is 17.82 units
<h3>SOH CAH TOA identity</h3>
1) From the first figure.
Opposite side = x
Adjacent = 12
Using the SOH CAH TOA identity
tan53 = opp/adj
tan53 = x/12
x = 12tan53
x = 15.92 units
2) Using the SOH CAH TOA identity
cos27 = adj/hyp
cos27 = x/20
x = 20cos27
x = 17.82units
Hence the value of x from the figure is 17.82 units

Answer:</h3>
<u>Perimeter of rectangular garden = 2(l + b)</u>
- 2(y + 2 + 4y - 1)
- 2y + 4 + 8y - 2
- 10y + 2.
<u>Hence, perimeter of given garden is 10y + 2</u>.
