Answer:
last choice
Step-by-step explanation:
sin(theta) is positive
tan(theta)=sin(theta)/cos(theta) is negative
If sin(theta) is positive and tan(theta) is negative, then cos(theta) is negative because +/-=-
So we are looking for the quadrant where sine is positive and cosine is negative or when x is negative and y is positive.
This is in quadrant 2 so our angle theta is between 90 and 180 degrees.
Answer:
C
Step-by-step explanation:
The table shows the sign of the function is the opposite of the sign of x, so ...
as x → ∞, f(x) → -∞; as x → -∞, f(x) → ∞ . . . . . matches the 3rd choice
<u>Given</u> -
- the diameter of a semicircle is 6 yards.
ie. d = 6yd
ps - use 3.14 for a
<u>To find</u> -
- the semicircle's perimeter
<u>Solution</u> -
As we know the formula to find the perimeter of the semicircle is 2r + πr.
But A.T.Q we are only provided with the diameter. As we know that the radius is half of the diameter. ie, r = d/2.
Hence, d = 6
r = 6/2
r = 3 yd
Perimeter of semicircle = 2r + πr
Perimeter of semicircle = 2(3) + 3.14(3)
Perimeter of semicircle = 15.42 yd
<u>Hence forth the semicircle's perimeter is 15.42 yd</u>
Solution:
We are given that lena sells cosmetics and recieves commissions of 45%.
She sold $200 worth of cosmetics to one customer.
It mean she will get a commission of 45% on $200. So we will find 45% of 200 and the resulting value will be the comission of Lens.
45% of 200
Comission recieved
It mean that when leena sells cosmetics of $200, she gets a comission of $90.
