Answer: 65 degrees
Step-by-step explanation:
Since cooler means lower, then that means subtraction. So, 13 subtracted from 78 is 65.
If you know calculus, you can take the derivative and find the critical point.
The simpler method would be to complete the square. We have
The first term will always be negative, so whenever it vanishes, we're left with the maximum value at
, so the answer is C.
Answer:
y=-7x-30
Step-by-step explanation:
y-y1=m(x-x1)
y-5=-7(x-(-5))
y-5=-7(x+5)
y=-7x-35+5
y=-7x-30
Answer:
The square JKLM is a square with 4 right angles
It is a parallelogram
Step-by-step explanation:
She will need 288 ft of Christmas lights
Step by Step:
First we find how many feet is needed to go around 1 window. We do this by adding up all four of its sides.
4+4+2+2= 12
Because there are 15 windows be multiply the feet needed for 1 window by 15.
12•15=180
Repeat the first two steps for the garage doors to find that she needs 108ft of lights for 3 garage doors and add the feet needed for the windows to the feet needed for the garages
180+108=288
