Answer:
F
Step-by-step explanation:
So you would use rise over run so its 4/5 but its negative so you go 4 down and 5 right. So 4 down 5 right is equal to -4/5 which is your slope.
Answer: 97.7 in
Step-by-step explanation: The perimeter is another name for circumference. Since we know that the formula for circumference is 2(pi)r, but we only want half of that.
Note that 2r is another way of writing the diameter (d).
In this case, we can use the formula d(pi)/2 + d (we’re adding d because d(pi)/2 will only give us the perimeter of the arch.
38(pi)/2 = 59.66
59.66 + 38 = 97.66
Rounded, that would be 97.7 in
Answer:
ET = 80/A^2
Step-by-step explanation:
First, isolate the variables that you need, which is E and T, using the two equations you were given.
EA = 8
E = 8/A (divide A on both sides to isolate E)
AT = 10
T = 10/A (divide A on both sides to isolate T)
Now, substitute.
ET --> (8/A) x (10/A) = 80/A^2
The top left is the correct answer, because the sides are parallel.
Hope this helps!
-16t^2+400=0
16t^2=400
take square root on both sides.
4t=20
t=20/4
t=5
