Which of the following circles lie completely within the fourth quadrant? a. (x + 3)^2 + (y - 2)^2 = 25 b. (x - 4)^2 + (y + 2)^2 = 32 c. (x - 5)^2 + (y + 7)^2 = 16 d. (x- 3)^2 + (y + 4)^2 = 1
y = 0
we are given the following equation and we are to find the value of y when x equals to 28:
substituting the given value of x in the above equation:
therefore, y = 0 when x = 28.
volume of the pyramid would be 22 cubic inches.
a square pyramid has a third of the volume of a cube so 66/3 = 22
(hope this ! if it did give me brainliest! )
you can get there a couple of ways. one makes use of the secant rules that tell you
pq × pr = ps × pt
substituting for pr and pt, you have
pq × (pq + qr) = ps × (ps + st)
pq² + pq×qr = ps² + ps×st
substituting pq for ps everywhere, we have
pq² + pq×qr = pq² + pq×st
dividing by pq gives
pq + qr = pq + st
and subtracting pq leads us to the conclusion
qr = st
another way to look at it is to draw the chord qs. then δqps is an isosceles triangle, and the perpendicular bisector of qs bisects ∠p and also goes through the circle center. then the figure is symmetrical about that diameter secant, making qr ≅ st.
the answer is. $5170.00
hope it ^^
