Answer:Im pretty sure it's quadratic
Step-by-step explanation:
The reason is because if you plot these on a graph they would make a "U" shape witch mean it's a parabola if it were exponential it would not make a "u" shape because it would keep going up and never come back down at a exponential rate.
I think so C is correct
Because is true.
Answer:
<h3>36 and 12</h3>
Step-by-step explanation:
Let the two positive integers be x and y.
If their product is 432, then
xy = 432 ......... 1
Also if the sum of the first plus three times the second is a minimum, then;
p(x) = x + 3y
From 1;
y = 432/x ..... 3
Substitute 3 into 2;
p(x) = x+3y
p(x)= x + 3(432/x)
p(x) = x + 1296/x
Since the expression is at minimum when dp(x)/dx = 0
dp/dx = 1 + (-1296)/x²
dp/dx = 1 -1296/x²
0 = 1 -1296/x²
0 = (x²-1296)/x²
cross multiply
0 = x²-1296
x² = 1296
x = √1296
x = 36
Since xy = 432
36y = 432
y = 432/36
y = 12
Hence the two positive numbers are 36 and 12
To answer this question, we just need to subtract the low ( -22 ) from his much it rose ( 35 ).
So the highest temperature was 13.
The length of each side of the square is 3 ft.
<u>Step-by-step explanation:</u>
We have , A composite figure is formed by combining a square and a triangle. Its total area is 52.5 ft. The area of the triangle is 43.5 ft . We know that area of a square = 
. According to question:
area of square =
area of triangle = 43.5 ft
total area = 52.5 ft.
Total area = area(square+triangle)
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, the length of each side of the square is 3 ft.
