Answer:
$512
Step-by-step explanation:
Charges at the first hotel are ...
4(168 -40) = 4(128) = 512
Charges at the second hotel are ...
(4-1)(185) = 3(185) = 555
The first hotel offers the better rate: $512 for four nights.
Answer:To get the graph of the given parabola, we will use the equation of the parabola to check if given points in options are lying on that parabola or not. If they lie on the graph of parabola, then they would satisfy the equation, else not. We will use vertex form of parabola to get its vertex.
Thus, by below shown calculations, we have
Option A: On a coordinate plane, a parabola opens up. It goes through (-6, 0), has a vertex at (-2, -8), and goes through (2,0)
Answer:
35-7x
Step-by-step explanation:
Multiply parenthesis by -7
Triangle Area = .5 * base * height
48 = .5 * (x +4) * x
48 = (.5x + 2) * x
48 = .5x^2 + 2x
.5x^2 + 2x -48 = 0
x = 8
base = 12
Answers:
4. m PQ: 50 degrees
m PXQ: 310 degrees
5. m PQ: 90 degrees
m PRQ: 270 degrees
Explanation: the central angle is equal to its corresponding arc. The larger arc is found by doing 360- smaller arc degrees.
