From the points given we know that the rectangle is 3 points wide and 2 points tall. If we rotate it
around the x axis then we will receive the lying cyllinder which will be 3 points tall and 2 points wide (so its radius is 2/2 = 1 point). Now we can find the surface area of the cyllinder using appropriate formula:
Answer:
Segment DE is half the length of segment AC. -- Substitution property of equality
Step-by-step explanation:
Here is given a proof for proving line joining mid segment is parallel and half the length of third side.
Stepwise proof is given in two columns
We find that for every line there is a justification as
STatement Justification
D and E coordinates found out MId point formula
DE and BC are measured Distance formula
DE=1/2 BC Substitution property of equality
This justification was missing in the given proof and with this included proof would be complete
Answer:
x² -3x - 54
Step-by-step explanation:
given roots of a polynomial are 9 and -6
this means that (x-9) and (x+6) are factors of the polynomial.
To get the polynomial with the least degree, simply multiply the two factors to obtain a quadratic expression (degree 2)
(x-9) (x+6)
= x² + 6x -9x -54
= x² -3x - 54
Adults pay = $33.60
Children pay = $16.80 (it's half price but if they take a round trip it's double the price. Therefore it's $16.80) then multiply both by two and add them together.
2 ($33.60+$16.80) = $100.80
