I believe the answer is 113 ft²... divide the shape into 2 different rectangles and multiply 7 × 11 which equals = 77. Then take 11-5 to get 6, then 6 × 6 to get 36.
77 + 36 = 113 ft²

(A) f(x) = 7 is constant, so f(x + h) = 7, too, which makes f(x + h) - f(x) = 0. So f'(x) = 0.

(B) f(x) = 5x + 1 ==> f(x + h) = 5 (x + h) + 1 = 5x + 5h + 1

==> f(x + h) - f(x) = 5h

Then

$\displaystyle f'(x) = \lim_{h\to0}\frac{5h}h = \lim_{h\to0}5 = 5$

(C) f(x) = x ² + 3 ==> f(x + h) = (x + h)² + 3 = x ² + 2xh + h ² + 3

==> f(x + h) - f(x) = 2xh + h ²

$\implies\displaystyle f'(x) = \lim_{h\to0}\frac{2xh+h^2}h = \lim_{h\to0}(2x+h) = 2x$

(D) f(x) = x ² + 4x - 1 ==> f(x + h) = (x + h)² + 4 (x + h) - 1 = x ² + 2xh + h ² + 4x + 4h - 1

==> f(x + h) - f(x) = 2xh + h ² + 4h

$\implies \displaystyle f'(x) = \lim_{h\to0}\frac{2xh+h^2+4h}h = \lim_{h\to0}(2x+h+4) = 2x+4$

A bicycle training wheel has a radius of 3 inches. The bicycle wheel has a radius of 10 inches.Approximately how much smaller, i

choli [55]

Answer:

Area of training wheel is 285.74 square inches smaller than bicycle wheel.

Step-by-step explanation:

Given : A bicycle training wheel has a radius of 3 inches. The bicycle wheel has a radius of 10 inches.

To find : How much is the the area of the training wheel than the area of the regular wheel?

Solution :

→A bicycle training wheel has a radius of 3 inches.

Area of of the training wheel is $A=\pi r^2$

where r is the radius and r=3 inches (given), $\pi =3.14$

$A_1=\pi r^2$

$A_1=(3.14) (3)^2$

$A_1=3.14\times9$

$A_1=28.26 inches^2$

Area of the bicycle training is 28.26 square inches.

→ The bicycle wheel has a radius of 10 inches.

Area of of the bicycle wheel is $A=\pi r^2$

where r is the radius and r=10 inches (given), $\pi =3.14$

$A_2=\pi r^2$

$A_2=(3.14) (10)^2$

$A_2=3.14\times100$

$A_2=314 inches^2$

Area of the bicycle wheel is 314 square inches.

The area of the training wheel than the area of the regular wheel is

$Area=314-28.26=285.74$

Rounded to nearest hundredth the area is 285.74 square inches.

Therefore, Area of training wheel is 285.74 square inches smaller than bicycle wheel.
