There are 360° in a full circle. Our given arc subtends an angle of 30°, and since 360 = 30 x 12, we can also multiply the length of the arc by 12 to find that our circumference is 8 x 12 = 96.

theta = arc/radius, theta being in radian, so theta = pie / 6, radius = arc / theta = 15.278 (unit if the arc) and then multiply that by 2 pie to get the circumference sorry :D, if you have a guide answer and my answer is wrong please tell me to revise

Which trail is the closest in length to 10.5 kilometers?
Yuliya22 [10]
First of all you calculate the difference between the numbers:
10.5 - 10.653 = -0.153
10.5 - 10.592 = -0.092
10.5 - 10.732 = -0.232
10.5 - 10.484 = 0.016

You then select the difference with the smallest number (ignoring the positive and negative symbols). That happens to be the last one.

This means that the answer will be D) Spruce Trail.

the polynomial ky^3+3y^2-3 and 2y^3-5y+k when divided by (y-5) leave the same remainder in each case. Find the value of k.
marshall27 [118]

Answer:

k=\frac{153}{124}

Step-by-step explanation:

According to the Remainder Theorem; when P(y) is divided by y-a, the remainder is p(a).

The first polynomial is :

p(y)=ky^3+3y^2-3

When p(y) is divided by y-5, the remainder is

p(5)=k(5)^3+3(5)^2-3

p(5)=125k+75-3

p(5)=125k+72

When the second polynomial:

m(y)= 2y^3-5y+k is divided by y-5.

The remainder is;

m(5)= 2(5)^3-5(5)+k

m(5)= 225+k

The two remainders are equal;

\implies 125k+72=225+k

\implies 125k-k=225-72

\implies 124k=153

k=\frac{153}{124}
