To solve for the time it reach the maximum height, you must solve the first derivative of the function and equate it to zero
<span>h(t) = −4.9t^2 + 14.7t + 1</span>
dh/ dt = -9.8t + 14.7
then equate to zero
-9.8t + 14.7 = 0
solve for t
t = 1.5 s
then the maximum height is when t = 1.5
<span>h(t) = −4.9t^2 + 14.7t + 1
h(1.5) = </span><span>−4.9(1.5)^2 + 14.7(1.5) + 1
h(1.5) = 12.025 m
</span>
Answer:
We can write out 3! (three factorial) as 3x2x1, and we can write out 5! as 5x4x3x2x1. This means that, since 3x2x1 is on the top and the bottom of the fraction, it cancels out. This leaves us with 1 on top, and 4x5=20 on the bottom.

Answer:
x = 4
Step-by-step explanation:
I'd suggest you write (1/24)x = 1/6 to avoid any ambiguity about the coefficient of x.
Multiplying both sides by 24 (the LCD) will eliminate the fractions:
24(1/24)x = 24/6, or x = 4.
Answer:
The missing justification is the transitive property.
Step-by-step explanation:
The missing justification is the transitive property. The transitive property states that: If a = b and b = c, then a = c.
Answer:
66 degrees
Step-by-step explanation:
assuming that the line RN crosses line QO in the mid point, and that from that point to R, and to N, are the same length, then the angles R and N should be the same making angle O the complimentary angle, that would be 66 degrees
