Answer:
$24
Step-by-step explanation:
For a markup, use the formula <em>a = ( 1 + p ) × w. </em>
!!! Remember, <em>a </em>is the selling price, and <em>w </em>is the original price !!!
!!! The <em>p </em>is the percent in decimal form. 20% as a decimal is 0.20 (move the decimal twice to the left) !!!
<em />
Inserting the values, it should look like <em>a = ( 1 + 0.20 ) × 20 </em>
<em>a = 1.20 × 20 </em>
<em>a = 24</em>
<em />
Hence, the new selling price is $24.
Hope this helps! :)
Answer:
a. (-3, 2).
b. √65
c. (x + 3)^2 + (y - 2)^2 = 65
Step-by-step explanation:
a. The center is the midpoint of the diameter PQ.
= (-10+4)/2, (-2+6)/2
= (-3, 2).
b. The radius is the distance from the center to a point on the circle.
Take the point (4, 6):
The radius = √((-3-4)^2 + (2-6)^2)
= √65.
c. The equation of the circle is:
Using the standard form
(x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center and r = the radius:
it is (x - (-3)^2 + (y - 2) = 65
= (x + 3)^2 + (y - 2)^2 = 65.
Parallel lines are both vertical and they don’t meet.
The answer of this question is 42
So this is taking this equation and plugging it into the quadratic formula -b+- (sqrt (b^2)-(4)ac)/2a so your A value is 1 B value is 3 and C value is -5 so it’s B&E
