5 0

Answer:

70°

Step-by-step explanation:

m\widehat {BC} = 90\degree - m\widehat {CD}

m\widehat {BC} = 90\degree -20\degree

m\widehat {BC} = 70\degree

What polynomial should be subtracted from the polynomial y^2–5y+1 to get the difference equal to: 5
monitta

Answer:

y^2 - 5y - 4

Step-by-step explanation:

So you want f(y) such that

(y^2-5y+1) - f(y) = 5

Subtract both sides by (y^2-5y+1):

-f(y) = 5 - (y^2-5y+1)

-f(y) = -y^2 + 5y + 4

f(y) = y^2 - 5y - 4

So the polynomial you are looking for is y^2 - 5y - 4

I NEED HELP!!!!!!!! WHAT IS THIS!? I'll mark BRAINLIEST if anyone can answer correctly!
VikaD [51]

So the rule with dividing exponents of the same base is to just subtract the exponents. Using this rule, we solve the equation as such:

\frac{p^{-4}q^5r^6}{p^{-3}q^1r^{-2}}=p^{-4-(-3)}q^{5-1}r^{6-(-2)}=p^{-1}q^4r^8

Next, assuming that you only want positive exponents, to get from a negative exponent to a positive one the rule is x^{-m}=\frac{1}{x^m} . Using this rule, your final answer is going to be \frac{q^4r^8}{p^1}
