90 POINTS WILL GIVE BRAINLIEST for which value of theta is cot theta equal to cos theta
Angelina_Jolie [31]

Answer:

...so cos t = cot t can only happen when cos t is 0 or sin t is 1. (But sin t = 1 only happens when cos t = 0, so cos t = 0 is enough.)  

arccos(0) is pi/2, plus or minus any multiple of pi.

Step-by-step explanation:

 

cotθ = cosθ  

cosθ/sinθ = cosθ  

sinθ = 1  

θ = π/2

pi also = to 3.14 etc.

Patricia scored 80% on her math test. She missed 4 problems. How many problems were on the test?
Yuri [45]

Hey there!

If she missed 4 problems, and that took off 20%, that means 4 is 20% of the total items.

20% is the same as 1/5 of the total amount, since there are 5 20s in 100.  

So, we can simply multiply 4 by 5 to get the total amount of problems.

4 x 5 = 20

This means there were 20 problems on the test.

Hope this helps!

If `-5c-2` equals `-2`, what does `-20c-8` equal?
Setler79 [48]

Answer:

-20c - 8 = -8

Step-by-step explanation:

Solve for c.

Set up an equation: -5c - 2 = -2  

Add 2 to both sides: -5c = 0

Divide both sides by -5: c = 0

Plug the value of c into the expression: -20(0) - 8

Multiply: 0 - 8

Subtract: -8
