To support a tree damaged in a storm, a 12-foot wire is secured from the ground to the tree at a point 10 feet off the ground. T

VARVARA [1.3K]

Answer:

(D)56.4

Step-by-step explanation:

According to the question, Let AB=10, AC=12 and m∠B=90°.

Thus, from ΔABC, using trigonometry, we have

$\frac{AB}{AC}=sinx$

$\frac{10}{12}=sinx$

$\frac{5}{6}=sinx$

$sinx=0.83$

$x=sin^{-1}(0.83)$

$x=56.4$

Therefore, at $x=56.4$ the wire meet the ground.

The radius of a circle is decreasing at a rate of 6.56.56, point, 5 meters per minute. At a certain instant, the radius is 12121

Ilia_Sergeevich [38]

Answer:

The rate of change of the area of the circle is approximately $-490.09 \ m^2/min$ .

Step-by-step explanation:

Given:

$\frac{dr}{dt} = -6.5 \ m/min$

radius $r =12 \ m$

We need to find the rate of change of the area of the circle at that instant.

Solution:

Now we know that;

Area of the circle is given by π times square of the radius.

framing in equation form we get;

$A= \pi r^2$

to find the rate of change of the area of the circle at that instant we need to take the derivative on both side.

$\frac{dA}{dt}=\frac{d(\pi r^2)}{dt}\\\\\frac{dA}{dt}= 2\pi r \frac{dr}{dt}$

Substituting the given values we get;

$\frac{dA}{dt}= 2\times \pi \times 12 \times -6.5\\\\\frac{dA}{dt}\approx -490.09 \ m^2/min$

Hence The rate of change of the area of the circle is approximately $-490.09 \ m^2/min$ .

Ms. Metzger is cooking chicken tacos for dinner. She is using the

netineya [11]

The amount of cheese she will use if she uses 4 pounds of chicken is; A: 0.3 cups

How to solve proportions?

We are told that the proportion that she is using is;

¹/₄ cup of cheese per 3 lbs of chicken

Now, we want to find the number of cups of cheese per 4 lbs of chicken

Thus;

If ¹/₄ cup of cheese is used per 3 lbs of chicken, then it means that;

Number of cups of cheese for 4 lbs of chicken = (4 * ¹/₄)/3

Number of cups of cheese for 4 lbs of chicken = 1/3 = 0.3 cups

Thus, we conclude that the amount of cheese she will use if she uses 4 pounds of chicken is; A: 0.3 cups
