The vertex is (-4,-3)
The axis of symmetry is x=-4
and the transformations are:
Answer:
Equation of parabola: 8*(y - 2) = (x - 3)^2
or
y = (1/8)*(x - 3)^2 + 2
Step-by-step explanation:
focus at (3,4) and its directrix y = 0.
Focus equation: (h, k + c) = (3, 4)
Directrix equation y = k - c = 0
so h = 3, k + c = 4, k - c = 0
Solve the system : k + c = 4 and k - c = 0
add the equations together: k + c + k - c = 4 + 0
2k = 4
k = 2
so k + c = 4, 2 + c = 4, c = 2
4c (y - k) = (x - h)^2
4*2 *(y - 2) = (x - 3)^2
8*(y - 2) = (x - 3)^2
Answer:
70 square inches
Step-by-step explanation:
We have to find the area of the rectangle and this would help us determine how much paint he would need to paint his rectangle
Area of a rectangle = Length × Width
Length = 10 inches
Height = 7 inches
Area of the rectangle = 10inches × 7 inches
= 70 square inches
Therefore, he would be needing 70 square inches of paint in order to paint his rectangel
The answer is
, x = 3/4 pound.
Let m be the weight of math textbook.
Let x be the weight of language arts class.
Math textbook weighs 4/5 of a pound less than 4 times the weight of the book <span>for language arts class:
m = 4x - 4/5
Since </span>
