Answer:
5.25
Step-by-step explanation:
The fact that the graph crosses the x-axis means the hyperbola opens to the left and right. Hence its equation is ...
x^2/a - y^2/b = 1
The point (-2, 0) helps us find "a":
(-2)^2/a - 0/b = 1
4 = a
Then we can find "b" from the other fully-specified point.
(-3)^2/4 - 4^2/b = 1 . . . . . . substitute (-3, 4) for (x, y)
b = 16/(9/4 -1) = 64/5 . . . . solve for b
Then the third point will satisfy ...
t^2/4 - (5/64)·2^2 = 1 . . . . . . substitute (t, 2) for (x, y)
t^2 = 4·(1 +5/16) = 4 +5/4 . . . . solve for t^2
t^2 = 5.25

Answer:
D (i hope)
Step-by-step explanation:
When you minus the highest to the lowest it is added by 10 so
160-140= 20
140-110=30
110-70= 40
70-20= 50
I had added 10 to 160 and got 170
The area of a rectangle equals length times height. (A=LH)
A=256.5 L=18
Plugging in the numbers into the equation, you get 256.5=18H. (like I substituted the numbers in)
next if you divided both sides by 18, it will cancel out the 18 in the 18H side of the equation.
So, it is 256.5/18 equaling H
256.5 divided by 18 is... 14.25
That means the height is 14.25 an the length is 18.
the perimeter is all of the sides added together. in a rectangle, the sides opposite each other are the same.
So you have two sides that are 14.25 and two that are 18 meters long.
14.25+14.25+18+18 equals the perimeter then.
So the answer would be... 64.5!
