Step-by-step explanation:
We are given a theta degree measure of sin in a specific interval. We are asked to find half of that degree measure.
The interval it ask us to find it in is between 2 pi and 5 pi over 2.
That is 360 degrees to 450 degrees. If you use reference angles, that is between the 0 degrees and 90 degrees. So that means our measure is going to be in the 1st quadrant.
Replace x with theta
We dont know cos x but we can use the pythagorean trig theorem to find cos x.
Cosine in 1st quadrant is positive so 3/5 is cos x.
Replace 3/5 for cos x.
The answer is
1.) 3124
2.) 3214
3.) 3412
4.) 1432
5.) 1342
6.) 1234
7.) 1423

Answer:
4.356 × 10⁶ square feet or 4.356 × 10⁶ ft² of pizza per year
Step-by-step explanation:
Scientific notation is a means, method or way that is used in mathematics to write very large or small real numbers in a very short form or compressed form.
Scientific notation uses exponents or 10 raised to the power of a particular number to write huge or small real number in a decimal form.
In the question, we are asked to express the area in square feet as a scientific notation.
The area = 4,356,000 square feet of pizza per year
4,356,000 square feet of pizza per year in scientific notation =
4.356 × 10⁶ square feet of pizza per year.
Step-by-step explanation:
just subtract it
answer is 122.709
