Answer:
= 10root6 i
Step-by-step explanation:
= 5 • 2root6 i
= 10root6 i
Answer:
16 ÷ 8 = 2 16 ÷ 4 = 4 16 × 0 = 0 16 × 2 = 32.
or
16*2=32
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

Answer: 
Step-by-step explanation:
It is important to remember that, by definition, proportional relationships have the following form:
Where "k" is the constant of proportionality.
We know that Maddy assume that the relation between the volume and the weight is proportional.
Then, let be "V" the volume in liters and "w" the weight in kilograms.
We can write the following equation:
So, if the boat of 555 liters weights 7.5 kilograms, we can find "k":
In order to solve the exercise, substitute the value of "k" and 
into the equation and solve for "w". Then:
Answer:
22
Step-by-step explanation:
5 1/2 divided by 1/4 is the same thing as times 4
5 1/2 times 4 equals 22 since 5*4 is 20 and 1/2 times 4 is 2
20+2 equals 22
