Answer:

The answer is D.

Step-by-step explanation:

First, you have to find the area of circle using the formula :

A = π × r²

A = π × 3²

A = 9π

Given that PHU is an equilateral triangle so all sides have a degree of 60°. Next, you have to find the area of minor sector of P and U by using the formula :

A = (θ/360) × π × r²

A = (60/360) × π × 3²

A = 1.5π

Lastly, you have to subtract the area of sector from the area of circle in order to find the area of shaded region :

A = (9π × 2) - (1.5π × 2)

A = 18π - 3π

A = 15π

Guys i need ur help fast please ​

Answer:

a) -3

b) 5

c) 7

d) 4

Step-by-step explanation:

We have the function p(x)=5x^3-3x^2+2x^5+7

a) We need to find the coefficient of x^2.

This means that we need to find out what number is alongside the x^2 in this equation. From the function, we can find that it is -3

b) Now we need to find the degree of p(x). Recall that the degree refers to the highest power of x that is present. As x^5 is the largest power, our degree would be 5.

c) The constant term refers to the number within the function that does not have any x's with it. In this function, that number would be 7.

d) Now we need to find the number of terms. For this one, we just need to count how many terms are separated by + or - signs. There are 4 in this function.

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
frozen [14]

Note: Consider we need to find the vertices of the triangle A'B'C'

Given:

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.

Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).

To find:

The vertices of the triangle A'B'C'.

Solution:

If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then

(x,y)\to (y,-x)

Using this rule, we get

A(-3,6)\to A'(6,3)

B(2,9)\to B'(9,-2)

C(1,1)\to C'(1,-1)

Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).

A salesperson sells $3600 in merchandise and earns a commission of $576. Find the commission rate.
Kitty [74]

Total sales = $3600

Commission earned on $3600 = $576

Commission rate can be calculated as = \frac{576}{3600}\times100

= 16%

Hence, commission rate is 16%
