Answer:
a. [tex]y = -(x+1)^2+4[/tex]
b. [tex]y = \frac{1}{2} (x-2)^2-3[/tex]
Step-by-step explanation:
a. Vertex is (-1, 4)
so you get
[tex]y = a(x+1)^2+4[/tex]
plug in (1, 0) and get the a value
[tex]0 = a(1+1)^2+4\\0 = a*2^2 + 4\\0 = 4a + 4\\-4 = 4a\\a = -1[/tex]
final eq:
[tex]y = -(x+1)^2+4[/tex]
b. Vertex is (2, -3)
so you get
[tex]y = a(x-2)^2-3[/tex]
plug in (0, -1) and get the a value
[tex]-1 = a(0-2)^2-3\\-1 = a*(-2)^2 -3\\-1 = 4a -3\\2 = 4a\\a = \frac{1}{2}[/tex]
final eq:
[tex]y = \frac{1}{2} (x-2)^2-3[/tex]

Katie is planting a garden for her science fair project she needs 2/3 of a cup of soil to go in a different parts how many cups of soil does she need in total
Answers
Katie requires 16/3 cups of the soil for planting a garden for her science fair.
How to calculate the total amount?Algebra is a mathematical technique for calculating unknown values.
Variables represent unknown parameters in an equation and are usually categorized by a letter of the alphabet. The value of the variable is determined by isolating it.Now, for the stated question;
Katie has been planting a garden for her science fair project. She requires 2/3 of a cup of soil for each of the eight pots.
To calculate the total amount of soil required, multiply the amount required for one pot by the number of total pots.
Total soil = (2/3)×8
Total soil = (2×8)/3
Total soil = 16/3
Therefore, the total amount of the soil requires for the gardening in science fair is 16/3 cups.

y = 3x - 4
2y - 6x = -8
Answers
Answer:
Infinite solutions.
Any number.
Step-by-step explanation:
First, substitute one of the variables, x or y into one of the equations.
Since y is already isolated, substitute it in 2y - 6x = -8.
2 (3x - 4) - 6x = -8
Distribute 2 to 3x and -4.
6x - 8 - 6x = -8
Bring like terms together.
6x - 6x - 8 = -8
move -8 over to the other side of the equation and change its sign.
Or just add 8 to both sides (it is the same thing.)
You add 8 because it is to cancel out the negative 8 and get rid of it.
6x - 6x = -8 + 8
This equals 0 = 0 so there are infinite solutions to this system of equations.

The gas tank on the back of a tanker truck can be equated to a cylinder with a diameter of 8 feet and a length of 19 feet. A gallon of gas is approximately 231 cubic inches. The density of the gasoline is .0262 pounds per cubic inch. The driver has stopped at a local farm to fill a tank that has linear dimensions that are 2/3 the size of his tank. If the driver's tank was full and the farmer's tank was empty, what is the mass of the gasoline in each of the tanks after the smaller tank is full?
Answers
9514 1404 393
Answer:
driver's tank: 30,427 lbfarmer's tank: 12,811 lbStep-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr^2·h . . . radius r, height h
The radius of the driver's tank is half its diameter, so is (8 ft)/2 = 4 ft. Then the volume of that tank is ...
V = π(4 ft)^2·(19 ft) = 304π ft^3
Each cubic foot of gasoline has a mass of ...
(1728 in^3/ft^3)(0.0262 lb/in^3) = 45.2736 lb/ft^3
Then the total mass in the driver's full tank is ...
(304π ft^3)(45.2736 lb/ft^3) ≈ 43,238.3 lb
__
The farmer's tank is a scaled-down version of the driver's tank. It's volume will be scaled by the cube of the linear scale factor, so will be (2/3)^3 = 8/27 of the volume of the driver's tank.
The farmer's tank will hold a mass of (43,238.3 lb)(8/27) ≈ 12,811 lb.
The amount remaining in the driver's tank is 43,238 -12,811 = 30,427 lb.

The rational function that might have the given graph is [tex]y = - \frac{x}{(x+1)\cdot (x-1) }[/tex].
Step-by-step explanation:
This graph shows a rational function whose numerator is a first order polynomial and denominator is a second order, due to the presence of vertical asymptotes at [tex]x = -1[/tex] and [tex]x = 1[/tex]. The lead coefficient of the numerator must be 1, since horizontal asymptote must be [tex]y = 0[/tex] and intercept must be [tex]0[/tex], since [tex]y(0) = 0[/tex].
Then, we conclude that a rational function that might have the graph is:
