Answer:
5 miles
Step-by-step explanation:
Think of this like a triangle. From the bottom of the tower, to the top of the tower, to the point 3 miles away, and back to the bottom of the tower.
So we already have 2 side lengths. The height of the tower, 3 miles, and the base, 4 miles. In order to find the 3rd length, the distance from the top of the tower to the point 4 miles away from the bottom, we need to apply the formula A squared + B squared = C squared.
We have A and B, (3 and 4) and we need C.
A squared (3 squared) is 9
B squared (4 squared) is 16
so 9 + 16 = C squared
9 + 16 = 25
C squared = 25
square root of 25 is 5
C = 5
The distance from the top of the tower to the point 4 miles away is 5.
Range is the y-value. The y-value in an ordered pair is the second number
(x, y)
So pick out all the y-values from the given ordered pairs:
(-4, -2) -> -2
(3, 5) -> 5
(0, 4) -> 4
Now put them together.
The range is {-2, 4, 5}
The answer is 6 centimeters
To find the number of reptiles you would set up the equation like this
90=2x+10, x being the number of reptiles. Solve for that equation and you'll be good. Hope this helps :)
