Answer:
-3.25 degrees an hour
Step-by-step explanation:
-13 ÷ 4 = -3.25
Answer:
3.25 degrees/hour
Step-by-step explanation:
Last night, the temperature fell from 0°F to -13°F in 4 hour.
We need to find the average temperature change per hour. It can be calculated by dividing the change in temperature per unit time.
Change in temperature = -13°F -0°F = -13°F
So,
So, the change in temperature is 3.25 degrees/hour.

Hope it helps <3
the hypotenuse may be found by using the Pythagoras theorem
Did this a couple years ago, im kinda lost xD . sorry
Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
