Answer:
(-7,4)
Step-by-step explanation:
goal: (y-k)^2=4p(x-h)
y^2-8y=4x+12 Rearranged and added 4x and 12 on both sides
y^2-8y+(-8/2)^2=4x+12+(-8/2)^2 complete square time (add same thing on both sides)
y^2-8y+(-4)^2=4x+12+(-4)^2 (simplify inside the squares)
(y-4)^2=4x+12+16 (now write the left hand side as a square)
(y-4)^2=4x+28
(y-4)^2=4(x+7) factored...
vertex is (-7,4)
Answer-180cm3
Explanation-
The volume of a prism is base x height so v=bh
Here the base equals 4cm times 15m which gives 60cm.And then the height is 3cm.So the total is 15cmx4cmx3cm=180cm³
The width is 21 centimeters.
Hello! There is a markup, so the price goes up. We add 1 to the percentage rate in decimal form, then we multiply that by the original price to go straight to the new price. 45% in decimal form is 0.45. 1 + 0.45 is 1.45. 25 * 1.45 is 36.25. There. The new price of the jeans is $36.25.
Answer:
2B/( h-q)=a
Step-by-step explanation:
2B=ha-qa
Factor out an a
2B=a(h-q)
Divide each side by ( h-q)
2B/( h-q)=a(h-q)/( h-q)
2B/( h-q)=a
