4 5/6 would be your answer then you figure out how to take away the whole number
The graphs arey=(1/3)x^2
and y=3
they intersect at x=3
so the limits are x=0 and 3
to rotate it about y=k, minus k from every function
which evaluates to 72/5pi
A is asnwer
Old price: p1 = $ 3.90;
New price: p2 = $ 3.40.
The percentual decrease is given by
d(%) = [ (p2 - p1) / p1 ] * 100 %
d(%) = [ (3.40 - 3.90) / 3.90 ] * 100 %
d(%) = [ - 0.50 / 3.90 ] * 100 %
d(%) = - 0.128 * 100 %
d(%) = - 12.8 % (approximately)
So the price fell 12.8 % approximately.
I hope this helps. =)
Answer:
14 square units
Step-by-step explanation:
If you graph the points your triangle's height will be 4, and base would be 7.
<em>A = 1/2bh 4</em> x 7 = 28, 28 x 1/2 = 14.
Hope this helps :D
