Farmer bob's square plot ofland is slowly eroding away. Worried about the future of his farm. Farmer Bob measures the rate of er

kow [346]

Answer:

Option A.

Step-by-step explanation:

Area of a square is

$A=x^2$ .... (1)

where, x is side length.

The length of each side of his square plot is decreasing at the constant rate of 2 feet/year.

$\dfrac{dx}{dt}=2$

It is given that bob currently owns 250,000 square feet of land.

Fist find the length of each side.

$A=250000$

$x^2=250000$

Taking square root on both sides.

$x=500$

Differentiate with respect to t.

$\dfrac{dA}{dt}=2x\dfrac{dx}{dt}$

Substitute x=500 and $\frac{dx}{dt}=2$ in the above equation.

$\dfrac{dA}{dt}=2(500)(2)$

$\dfrac{dA}{dt}=2000$

Farmer bob is losing 2,000 square feet of land per year.

Therefore, the correct option is A.

Find the tangent of both angle A and angle B. Ignore what the picture says the numbers are the same.

Elena-2011 [213]

For the angle A we have:
tan (A) = C.O / C.A
tan (A) = 10/24
Simplifying we have:
tan (A) = 5/12
For angle B we have:
tan (B) = C.O / C.A
tan (B) = 24/10
Simplifying we have:
tan (B) = 12/5
Answer:
The tangent of angles A and B is given by:
tan (A) = 5/12
tan (B) = 12/5
