H(t) = -16t² + 16 t + 480
Factor out -16
-16(t² - t - 30)
t² - t - 30
(t + 5)(t - 6) ⇒ t(t-6) + 5(t-6) ⇒ t² -6t + 5t - 30 ⇒ t² - t - 30
t + 5 = 0 t - 6 = 0
t = -5 t = 6
The value of t is either -5 or 6 however time can't be measured in negative form; then, it took Rose 6 seconds to hit the water.
To get the answer, you need to solve the equation for x = 7.
f(7) = 3/7 + 2 - sqrt(7) - 3.
= 3/7 - 1 - sqrt(7).
If you need to simplify it further:
= -4/7 - sqrt(7).
If you need it in decimal form: = -3.2171798824
Answer:
I just took the quiz and got (0.15, 0.37)
Step-by-step explanation:
4.7244m
convert feet to inches using 1 foot = 12 inches
15.5 feet = 15.5 × 12 = 186 inches
multiply this by 2.54 to convert to cm
186 inches = 186 × 2.54 = 472.44 cm
now 1m = 100cm
divide 472.44 by 100 to convert to m
472.44 ÷ 100 =4.7244m
