Answer:
see explanation
Step-by-step explanation:
Given the polynomial

The rational zeros are all the possible factors of
dived by all the possible factors of
. Therefore we use the rational rots theorem to find all possible rational zeros.
To find all zeros we use the remainder theorem. Thus, we plug in all the rational zeros to determine which ones evaluate to zero. These are the real zeros. We could also use long division to find the remaining zeros as soon as we got the first zero with the remainder theorem.
Step-by-step explanation:
area of first triangle =1/2×112×202×sin30°
area of second circle=1/2×202×197×sin60.5°
- 1/2×202×197×0.870
- 17310.39m²
Total area of estates=area of first triangle +area of second triangle
hope it helps.
since we know the plumber charges $32 for one hour of work, if the plumber works
1 hour, that's 32(1)
2 hours........ 32(2)
3 hours.........32(3)
4hours...........32(4)
x hours...........32(x) => 32x.
the cost of materials is $46, so your total charge for getting the lizard out of the bathtub pipe is the hours rate plus the 46 bucks, namely 32x + 46, and incidentally we know that's $134.
![\bf 32x+46=134\implies 32x=88\implies x=\cfrac{88}{32}\implies x=\cfrac{11}{4} \\[2em] x=2\frac{3}{4}\impliedby \textit{2 hours and 45 minutes}](https://tex.z-dn.net/?f=%20%5Cbf%2032x%2B46%3D134%5Cimplies%2032x%3D88%5Cimplies%20x%3D%5Ccfrac%7B88%7D%7B32%7D%5Cimplies%20x%3D%5Ccfrac%7B11%7D%7B4%7D%20%5C%5C%5B2em%5D%20x%3D2%5Cfrac%7B3%7D%7B4%7D%5Cimpliedby%20%5Ctextit%7B2%20hours%20and%2045%20minutes%7D%20)
