Find the equation of a parabola in vertex form with given vertex and point.
Vertex (0,1) and passing through (-1,0)
keeping in mind that we could have a horizontally opening parabola or a vertically opening one using those values, let's use the vertical parabola type for the equation
[tex]~~~~~~\textit{vertical parabola vertex form} \\\\ y=a(x- h)^2+ k\qquad \begin{cases} \stackrel{vertex}{(0,1)}\\\\ \stackrel{"a"~is~negative}{o pens~\cap}\qquad \stackrel{"a"~is~positive}{o pens~\cup} \end{cases} \\\\[-0.35em] ~\dotfill[/tex]
[tex]y=a(x-0)^2+1\implies y=ax^2+1\qquad \textit{we also know that when} \begin{cases} x = -1\\ y = 0 \end{cases} \\\\\\ 0 = a(-1)^2+1\implies 0=a+1\implies \boxed{-1=a} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill y=-x^2+1\implies \stackrel{\textit{vertex form}}{y = -(x-0)^2+1}~\hfill[/tex]

1. A local charity is collecting food for the winter. They have asked 150
families to donate 5 cans of food. If 80% of the families donate 5 cans of
food, how many cans should the charity collect? *
The charity should collect 600 cans of food
Number of families that the charity asked to donate food = 150
80% of the families donated 5 cans of food
Number of families that actually donated 5 cans of food = (80/100) x 150
Number of families that actually donated 5 cans of food = 0.8 x 150
Number of families that actually donated 5 cans of food = 120
Number of cans donated by each family = 5
Number of cans donated by 120 families = 5 x 120
Number of cans donated by 120 families = 600
The charity should collect 600 cans of food

For the function: f(x) = 3x^2– 4x – 8, find and simplify
A. f(x) - f(a) divided by x-a
b.f(x +h) - f(x) all divided by H
Answer:
Step-by-step explanation:
A) (f(x) - f(a)) / (x - a)
(3x²– 4x – 8 - (3a² – 4a – 8)) / (x - a)
(3x²– 4x – 8 - 3a² + 4a + 8) / (x - a)
(3(x² - a²) – 4(x - a)) / (x - a)
(3(x - a)(x + a) – 4(x - a)) / (x - a)
3(x + a) - 4
B) (f(x + h) - f(x)) / h
(3(x + h)² - 4(x + h) - 8 - (3x² - 4x - 8)) / h
(3(x² + 2xh + h²) - 4x - 4h - 8 - 3x² + 4x + 8) / h
(3x² + 6xh + 3h² - 4x - 4h - 8 - 3x² + 4x + 8) / h
(3x² + 6xh + 3h² - 4h - 8 - 3x² + 8) / h
(3x² + 6xh + 3h² - 4h - 3x² ) / h
( 6xh + 3h² - 4h ) / h
(6xh + 3h² - 4h) / h
6x + 3h - 4
Explain how to determine whether the difference of two numbers is less than or greater than the first number.
Answer:
To determine if the difference of two numbers is less or greater than the first number, check the value of the first number, and the value of the second number.
(greater) - (lesser) = (positive)
(lesser) - (greater) = (negative)
(neg lesser) - (neg greater) = (positive)
(neg greater) - (neg lesser) = (negative)
For Example:
10 - 5 = 5
5 - 10 = -5
(-5) - (-10) = 5
(-10) - (-5) = -5

The retail price of a television set is $4500. If the buyer pays cash, the price is 10% below the retail price. If the set is bought on hire purchase, the buyer pays a down payment of $675 and 24 monthly instalments of $212.50. Determine the cash price.
4050 is the cash price of the television set whose retail price is $4500
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that the retail price of a television set is $4500
If the buyer pays cash, the price is 10% below the retail price
If the set is bought on hire purchase, the buyer pays a down payment of $675 and 24 monthly instalments of $212.50
we need to find the cash price.
We need to find the 10% of 4500:
Convert 10% to decimal form
10/100=0.1
Now multiply 0.1 with 4500
0.1×4500=450
Substract the 10% to the retail price:
4500-450=4050
Hence, 4050 is the cash price of the television set whose retail price is $4500

Answer:
y = -2x +2
Step-by-step explanation:
The slope is the y-change divided by the x-change:
m = (y2 -y1)/(x2 -x1)
m = (0 -2)/(1 -0) = -2
The y-intercept is the y-value when x=0: b = 2.
The slope-intercept equation is ...
y = mx +b
y = -2x +2
10 +4m when m = -2

Get rid of the denominator first by multiplying both sides by 3:

Answer:
252, 1 1/4, 308, 1 1/2
Step-by-step explanation:
5. The kitchen is 2 1/4 in by 1 3/4 in. 2 1/4in = 9/4in = 18ft. 1 3/4in = 7/4in = 14ft.
So we have 18ft by 14ft. The area is one side multiplied by the other side:
18 × 14 = 252ft^2.
6. 10/2 = 5. 5/4 in = 1 1/4in.
7. Bedroom 2 is 1 3/4in by 2 3/4in. 1 3/4in = 7/4in = 14ft. 2 3/4in = 11/4in = 22ft.
14ft × 22ft = 308ft^2 of carpet.
8. 12ft/2 = 6. 6/4 = 1 2/4 = 1 1/2 in.
Hope that helps!
