Answer:
15m
Step-by-step explanation:
When Ana is diving the time=0 therefore just substitute x=0 into h(x) and it will give you 15m
Using proportions, it is found that Student 2 is correct, as 37.6/0.1 = 376.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
One tenth is worth 0.1. How many tenths are there in 37.6? The division is given as follows:
37.6/0.1 = 376.
Hence student 2 is correct, as there are 376 tenths in 37.6.

Answer:
121π
Step-by-step explanation:
The formula for a circle is πr^2. But if given a diameter instead of radius, you simply divide by 2 because radius is half of a diameter.
Radius of this circle is 11 because you divide 22 by 2.
Then you follow the formula. 11^2=121.
Are you sure you want the length to be smaller than the width? It's not exactly the way they're defined. I'll solve it that way, but it's an odd question.
EquationsP = 2L + 2W
Area = L*W
Substitution and Solve2L + 2W = 36
L*W = 56
Divide the first equation by 2
L + W = 36/2
L + W = 18
Solve for L
L = 18 - W
Put this result in the second equation
W(18 - W) = 56 Remove the brackets
18W - W^2 = 56 Transfer the Left Side to the Right.
0 = W^2 - 18W + 56 Factor
0 = (W - 14)(W - 4)
W - 14 = 0
W = 14 <<<<<Answer
W - 4 = 0
W = 4
CommentBoth 14 and 4 are in cm
W = 14 cm <<<< answer
L = 4 <<<<< answer
