H=0
Therefore:
144t-16t²=0
t (144-16t)=0
We have two equations:
1)
t=0 (when the ball is released)
2)
144-16t=0
-16t=-144
t=-144 / -16=9 (this is the time )
Answer: the ball hit the ground in 9 s.
Answer:
The answer is "Option A"
Step-by-step explanation:
The domain is the collection of the value, which belongs to the separate variable (horizontal axis). So, to find a region with a graph, it must search for the function, which starts and end. And at all these levels we are searching at x-values.
Its starting point is (2,9) and the ending point is (8,3). Therefore, x= 2 to x=8 is the domain.
Answer:
33
Step-by-step explanation:
that is pretty close to a 45 degree angle so i would say about 33

Inc. must give an interest rate of 17.33 percent to generate a 10.40 percent
after-tax return and make Hugh indifferent between investing in the two bonds.
To solve for
the pretax rate of return, we can use this formula:
<span> After-tax return = Pre-tax return x (1 –
Marginal Tax Rate). </span>
10.40% = Pre-tax
return x (1 – Marginal Tax Rate);
<span>Pre-tax
return = 10.40% / (1 – Marginal Tax Rate) = 17.33%</span>
If you convert both fractions so that they both have the same denominator, you will get 20/30 (which is equivalent to 4/6) and 15/30 (which is equivalent to 5/10).
20/30 > 15/30, so 4/6 is greater than 5/10.
