Answer:
Step-by-step explanation:
f(-9+h)= (-9+h)² = h²-18h+81
f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81
f(-9+h)-f(-9)=h²-18h
(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18
lim (f(-9+h)-f(-9))/h = lim(h-18= - 18
h→0 h→0
La Respuesta es B. A2+B2=C2
Answer:
3 yards.
Step-by-step explanation:
The perimeter of a shape is the sum of the length of all the sides of the shape.
The shape described above is a pentagon since it has 5 sides.
One side is 3/5 yards long.
Hence, the perimeter will be:
P = 3/5 + 3/5 + 3/5 + 3/5 + 3/5
P = 3 yards.
The perimeter of the chicken coop is 3 yards.
Another way of solving this is to simply take 3/5 five times. That is:
P = 3/5 * 5
P = 3 yards.
We arrive at the same answer.
Answer:
Step-by-step explanation:
In any "solve for" scenario, you identify what operations are performed on the variable of interest, then undo them in reverse order.
Here, the square root of d is multiplied by a constant. To undo these operations, we first divide by the constant. That gives ...
Then, we square both sides of the equation to undo the square root:
This matches choice C.
"One rotation" would be the circumference of the wheel, which is
C = 2*pi*r, or (here) C = 2*pi*(8 inches) = 16*pi inches.
1 ft
Convert this to feet: 16*pi inches times ---------------
12 inches
Here "inches" cancels out and you are left with (4/3)pi ft.
So, one rotation of the wheel moves you and your bike forward (4/3)pi ft.
Divide this into 700 feet:
700 ft 2100
------------- = --------- rotations = 525 rotations (answer)
(4/3) pi ft 4
