Answer:
tanA = sinA / cosA = 3/5 / 4/5 = 3/4.
2(3x+2) I couldn’t find any other ones, your best bet would be to go into decimals or fractions if you want to find more.
A residual is a measure of how well a line fits an individual data point. Testing the two other points can really help to see how well the line fits.
6 foot =850
850÷6=141.667
then for 12 section
141.667x 12=1700 or
you find the ratio of 6:12
= 1:2
therefore 2×850=1700
Assuming the given is: 5u^7 - 21u^7
Since both algebraic terms are identical (both are using u^7), we can subtract the coefficients directly, as in: 5 - 21 = -16
Therefore, 5u^7 - 21u^7 = -16u^7
