Find the vertex of y=x^2-6x+1 A. ( 1 , 5 ) B. ( 4 , 1 ) C. ( 2 , -3 ) D. ( 3 , -8)

1 answer:

3 0

$h=\frac{-b}{2a}$

$k=f(h)$

$h=\frac{6}{2}$

$h=3$

$k=f(3)$

$f(3)=9-18+1$

$f(3)=-8$

The vertex is $(3,-8)$

Hope this helps.

頑張って!

Answer:

$1,682.70

Step-by-step explanation:

Convert the percent into a decimal by multiplying by 0.01: the percent in this problem is 6.5%, so when you multiply by 0.01, you get 0.065
Multiply the price by your new decimal: in this case, that would mean to multiply 1580 by 0.065, which gives you 102.7. <u>Keep in mind that this is just the tax, not your final answer.</u>
Add the tax you just calculated to the original price: add 102.7 to 1580 to get 1,682.7. That is your final answer.

arc = 2πr × $\frac{60}{360}$
