<u>Answer:</u>
Option D
<u>Step-by-step explanation:</u>
In this table, the constant of proportionality, which is just the number that each <em>x</em> value is multiplied by to get the corresponding <em>y</em> value, is 7. This is because, as shown by the first row of the table, 1*7=7, and, as shown by the third row of the table, 3*7=21. Therefore, in the second row of the table, <em>y</em> should be 14, as 2*7=14, while in the fourth row of the table, <em>y</em> should be 28, as 4*7=28.

The concept useful in finding the answer to this item is ratio and proportion, the ratio of the height of your friend with the shadow casted should be proportional to the height of the rock with the length of the shadow it cast. That is,
5.5 ft / 18 ft = x ft/ 209.5 ft
The value of x from the equation above is 64 ft.
Answer:
Step-by-step explanation:
f(x) = x²
f(4) = 4² = 16
f(1) = 1² = 1
f(-3) = -3² = 9
f(t) = t²
Always wise to us the ^ symbol to represent powers to avoid confusion
4^2 = 4² = 16
-3^2 = 9
t^2
if you are on a PC, the square symbol (²) can be typed by holding down the "alt" key while pressing and releasing "2","5","3" on the keypad, then release "alt". Unfortunately this does not work if you only have the row of numbers on the keyBoard to work with.
Step-by-step explanation:
Let:
x=length
(x/4)+1=width
P=2l+2w
62=2x + 2[(x/4)+1]
62=2x + 1/2x + 2
multiply both sides by 2
124=4x+x+4
5×=120
x=24
length: 24 inches
width: 7 inches
hope this helps!!
