Answer:
volume = 24,501.42
Step-by-step explanation: the way i did it:
first find the radius, 34 divided by 2 = 17π
then multiply the radius by itself 17 x 17 = 289
after, multiply 289 by 27 to get 7,803
then multiply 7803 by 3.14 to get 24,501.42
Hope this is correct!
(p.s.) if you do it on a calculator and use the pi symbol (π) the answer would be 24,513.84
First think out the equation, once you've done that multiply 3 by 25 to get 75
Answer:
The roots are
and 
Step-by-step explanation:
we have
To find the roots equate the polynomial to zero and cmplete the square
rewrite as perfect squares
take square root both sides
Remember that
substitute
therefore
The roots are
9514 1404 393
Answer:
-1/2
Step-by-step explanation:
The constant in the equation is the value that y has when x=0, because the x-term evaluates to zero when x=0. The constant term in this equation is -1/2, so that is the y-value when x=0.
(x, y) = (0, -1/2) . . . . where the graph crosses the y-axis
