Answer:
D. 108.25 sq in
Step-by-step explanation:
Area of triangle = bh/2
Area of bottom triangle = 4.3(5)/2 = 10.75
Area of a lateral triangle = 13(5)/2 = 32.5
Area of 3 lateral triangles = 3(32.5) = 97.5
Total surface area = 10.75 + 97.5 = 108.25
A is the correct answer because the parabolas never touch.
Answer:
y=8x-29
Step-by-step explanation:
Since we know the slope (m) is 8, we can plug it in the slope-intercept formula y=mx+b, making y=8x+b.
Now we need to find the y-intercept (b). To do that, you would need to plug in the points given to you, which were (4,3).
x=4, y=3... so 3=8(4)+b
Now you can solve for the variable b to find the y-intercept.
3=8(4)+b, multiply...
3=32+b, subtract 32 on both sides...
-29=b
Therefore, the y-intercept, or b, is -29.
The equation would be y=8x-29
Well, 1 is in the tenths place, which means it's equal to 1 tenth, or 1/10.

Answer:
47
Step-by-step explanation:
Evaluate the functions and find the required difference.
f(-2) = -(-2)^2 -7(-2) +4 = -4 +14 +4 = 14
g(6) = -5(6) -3 = -33
Then the difference is ...
f(-2) -g(6) = 14 -(-33) = 14 +33 = 47
