Step-by-step explanation:
f(x) = x² + 1, where x >= 0.
Let y be f(x).
=> y = x² + 1
=> x² = y - 1
=> x = √(y - 1) because x is non-negative.
Hence f^-1(x) = √(x - 1), where x >= 1.
I think the straw can hold about 15000 mm^3.
Answer:
75
Step-by-step explanation:
A triangle can only have 3 angles that add up to 180 degrees. Subtract 70 and 35 from 180 to get 75.
180=x+70+35
180-(70+35)=x
Dh/dt = -32t + 24
-32t + 24 = 0 when maximum
32t = 24
t = 24/32
t = 3/4
To find the maximum height just substitute "t" in
h = -16 (9/16) + 24(3/4) + 7
h = -9 + 18 + 7
h = 16ft
Answer:
- Not an isosceles trapezoid
Step-by-step explanation:
Plot the given points.
We can see and visually confirm this is not isosceles.
<u>(1,1) to (3, 3) distance is:</u>
<u>(5,3) to (8, 1) distance is:</u>
We see AD ≠ BC
The sides are not of the same length.
