A central angle of a circle measures π/3 radians.The length of the minor arc intercepted by this central angle is 7 inches. Find the length of the radius of the circle.
9514 1404 393
Answer:
6.68 in
Step-by-step explanation:
The length of an arc is given by ...
s = rθ . . . . θ in radians
Then the radius is ...
r = s/θ
r = (7 in)/(π/3) = 21/π in ≈ 6.6845 in
The radius of the circle is about 6.68 inches.
Answer:
Solution :-Angle of circle = π/3 r
Length of minor arc = 7 in
Now
We know that
Radius = Length/Angle
Radius = 7/(π/3)
Radius = 7/π × 3
Radius = 21/π

Find all exact solutions
2cos^2x=sinx+1
Please show work thank you!
Answer:
[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]2\cos^2(x)=\sin(x)+1[/tex]
And we want to find all solutions for x.
First, we should put the equation into terms of only one trigonometric ratio.
Since we are given cos²(x), we can turn this into sine. Recall the Pythagorean Identity which states:
[tex]\sin^2(x)+\cos^2(x)=1[/tex]
Therefore:
[tex]\cos^2(x)=1-\sin^2(x)[/tex]
By substitution:
[tex]2(1-\sin^2(x))=\sin(x)+1[/tex]
Distribute:
[tex]2-2\sin^2(x)=\sin(x)+1[/tex]
Isolate the equation:
[tex]2\sin^2(x)+\sin(x)-1=0[/tex]
We can factor:
[tex](2\sin(x)-1)(\sin(x)+1)=0[/tex]
Zero Product Property:
[tex]2\sin(x)-1=0\text{ or } \sin(x)+1=0[/tex]
Solve for each case:
[tex]\displaystyle \sin(x)=\frac{1}{2}\text{ or } \sin(x)=-1[/tex]
We can use the unit circle.
sin(x) = 1/2 for every π/6 and 5π/6. So, it will continue every 2π.
sin(x) = -1 every 3π/2. And this will also continue every 2π.
Hence, our solutions are:
[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]
Note:
If you only need the solutions within the interval [0, 2π), then it is:
[tex]\displaystyle x=\left\{\frac{\pi}{6}, \frac{5\pi}{6}, \frac{3\pi}{2}\right\}[/tex]
Given cos x = 3/5 and 3pi /2 < x < 2 and sin y = ─ square root 2/2,
and < y < 3pi /2; evaluate tan (x ─ y).

Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds. By what percentage did Mr. Pope decrease he weight?
a. (4%)
b. (7%)
c.(10)
d.(15%)
Mr. Pope decreased his weight by 4 percent.
What is percentage?A percentage is a portion of a whole thing written as a number between 0 and 100 instead of fraction.
Given that, Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds.
we need to find the percentage of decrease of his weight,
So, basically we will use here the concept of percentage change,
Formula = final amount - initial amount / initial amount x 100
Since, he lost 10 pounds and has 240 pounds so, initially he weighted = 240 + 10 = 250 pounds
So, percentage decreased = -10 / 250 x 100 = -4% [minus is the sign for decrease]
Hence, Mr. Pope decreased his weight by 4 percent.

Two angles are supplementary. One angle is 25°. What is the measure of the other angle?
Answer:
The other angle is 155°.
Step-by-step explanation:
Supplementary angles are two angles that have a sum of 180°.
I found my answer my subtracting 25 from 180 (180-25) and my difference was 155.
And, 155 + 25 = 180°.
Therefore, the other angle is 155°.
