Answer:
BAC=45
D=60
Step-by-step explanation:
Answer:
rational numbers are real numbers that statement is true
Step-by-step explanation:
because all rational numbers are belong to real number ,
real number contain all type of numbers rational and real number.
This is the formula for the surface area where r is the radius and h is the height. Finding the surface area will determine how much wrapping paper Jill needs (in inches squared).
The base measures 4 inches across. This means that the diameter is 4 inches. The radius is half the diameter (always). Thus, the radius is 2 inches. This means that r=2
The height is 10 inches. This means that h=10
The questions says to use 3.14 for π.
Use a calculator for this. Doing this by hand will take a painful amount of time.
This was what I got from a calculator. I did not round at all.
The surface area is 150.72 inches squared. Thus, Jill will need 150.72 inches squared of wrapping paper. I hope this is what you needed to help you understand! :)
The required steps that complete the proof are:
Step 1: Cofunction Identity
Step 5: Sine Difference Identity
Step 6: Cofunction Identity
Step 7: Cosine Function Is Even, Sine Function Is Odd
<h3>Trigonometry identity</h3>
Given the cosine function expressed as:
The first step is to apply the cofunction identity as shown:
- Step 1: Cofunction Identity
cos(90 - x) = sin x
cos(x - y) = sin (90-(x-y))
- Step 5: Sine Difference Identity
For the fifth step, you will apply the sine difference identity.
- Step 6: Cofunction Identity
To get the sixth step, you will apply the Cofunction Identity on the result in the fifth step.
The final step 7 will be
- Step 7: Cosine Function Is Even, Sine Function Is Odd
