Answer:
c. 6.5 seconds.
Step-by-step explanation:
We have been given that a a paper plane is thrown from the top of a 147-foot cliff into the water below, the height of the plane at any given time can be determined by the formula 
, where h is the height of the plane at t seconds.
To find the time, when plane will be at a height of exactly 20.25 feet, we will substitute 
in our given formula and solve for t as:
Take square root of both sides:
Since time cannot be negative, therefore, the plane will be at a height of exactly 20.25 feet after 6.5 seconds and option 'c' is the correct choice.
Answer: C. 0.3
Step-by-step explanation:
<em>To convert 1/3 so you can write it as a decimal, simply divide the numerator by the denominator, like this:</em>
<em></em>
<em>= 1/3</em>
<em>= 1 ÷ 3</em>
<em>≈ 0.3333333</em>
<em></em>
<em>Therefore, the solution to 1/3 as a decimal is as follows:</em>
<em></em>
<em>1/3 ≈ 0.3333333</em>
Use exponent rule: x^y * x^z = x^y+z
4^2 * 4^8
4^2+8
4^10
1,048,576
Best of Luck!

It can give you a clearer illustration of how long someone plays a video game.
P.S. my line would probably run off the grid. :-)<span />
I’m pretty sure it’s 6.4^4 • b^3
