Answer:
y=x^2 is the parent function
The transformations for y=-4(x+3)^2-5 are as follows
horizontal shift left 3 units
vertical shift down 5 units
reflection across the x-axis
vertical stretch
Answer:
The volume of this sphere =
Step-by-step explanation:
The region enclosed by the semicircle is revolved completely around the x-axis . Then the solid formed is a sphere of the same radius as that of the semicircle. We have to find the volume of this sphere. If the semicircle had center at the origin then the sphere also has the center at the origin.
Let the radius of given circle = r
Surface area of this sphere =
The volume of this sphere =
This is the volume of the required solid.
Answer:
I am not 100 percent sure, it's been a long time since I've done this type of math but I think that these are the answers
Step-by-step explanation:
1. x= -3, y=-3
2. x= 5, y= -2
3. x= -3, y = -7
4. x=2, y= 1
5. x=0, y= -4
Answer:
The correct option is;
DE = 2·(BC), AD = 2·(AB), and AE = 2·(AC)
Step-by-step explanation:
Given that we have;
1) The side AD of the angle m∠ADE corresponds to the side AB of the angle m∠ABC
2) The side DE of the angle m∠ADE corresponds to the side BC of the angle m∠ABC
3) The side AE of the angle m∠ADE corresponds to the side AC of the angle m∠ABC
Then when we have DE = 2·(BC), AD = 2·(AB), and AE = 2·(AC), we have by sin rule;
AE/(sin(m∠ADE)) = 2·(AC)/(sin(m∠ABC)) = AE/(sin(m∠ABC))
∴ (sin(m∠ADE)) = (sin(m∠ABC))
m∠ADE) = m∠ABC).
Hi,
7x²-2x-8=0, so a = 7, b= - 2, and c = -8.
You just need to apply the formula for square equations:
