Given: NB = 12 ft, Angle-120°<span>
Asked: area of the region that is not shaded.
Substitute the given values in the equation in finding the area of a circle.
</span>A = πr²
<span>A = ⅔π(12 ft)² </span>
<span>A = 96π ft²
(Since </span>120° is 1/3 of the circle. it is then understood that the unshaded parts must be 2/3 of the circle.)
Since you already have the area, find the area of the triangle to add it to the area of the circle to find the area of the unshaded part. By using a handy trigonometry, you can tell that their will be 2 triangles of 12 ft (if you are going to divide 120° angle). From this, you'll see that there will be one of the smaller triangles having a <span> the height of 6 ft and the base is 6√3 ft. Substitute the values.</span>
A = ½bh
<span>A = ½(6 ft)(6√3 ft) * 2 </span>
<span>A = 36√3 ft²
</span>
Add them up and you will have the exact answer 96π + 36√3 ft², when rounded to the nearest tenth, you will have <span> 364 ft². </span>
Answer:
474
Step-by-step explanation:
The equations are:
1. 2.35y = 4.70
2. k/3 = 17
3. 4 = 10w
4. 55x = 111
5. 8 = a/5
Answer:
the equations that apply are:
1. 2.35y = 4.70
3. 4 = 10w
4. 55x = 111
Step-by-step explanation:
We want to determine which if the equation we can use the division property of equality to solve.
1. 2.35y = 4.70
We can divide both sides by 2.35, so that
2.35y/2.35 = 4.70/2.35
y = 4.70/2.35
THIS WORKS
2. k/3 = 17
THIA DOESN'T WORK
3. 4 = 10w
dividing both sides by 10
4/10 = 10w/10
w = 4/10
THIS WORKS
4. 55x = 111
Divide both sides by 55
55x/55 = 111/55
x = 111/55
THIS WORKS
5. 8 = a/5
THIS DOESNT WORK
<u>Answer:</u>
A. y = -2 - cos(x-π)
<u>Explanation:</u>
<u>The general form of the trig equation is:</u>
y = A sin (Bx + C) + D
where:
A is the amplitude
is the period
is the phase shift
D is the vertical shift
<u>Now, let's check the choices:</u>
<u>A. y = -2 - cos(x-π)</u>
Therefore, the function has a phase shift of π
<u>B. y = 3 cos(4x)</u>
Therefore, the function has no phase shift
<u>C. y = tan(2x)</u>
Therefore, the function has no phase shift
<u>D. y = 1 + sin(x)</u>
Therefore, the function has no phase shift
<u>Based on the above,</u> the correct answer is A
Hope this helps :)
Answer:
Solution is 
Step-by-step explanation:
Given Differential Equation,
...............(1)
We need to solve the given differential equations using undetermined coefficients.
Let the solution of the given differential equation is made up of two parts. one complimentary solution and one is particular solution.
For Complimentary solution,
Auxiliary equation is as follows
m² - 2m + 1 = 0
