Which of the following are solutions to the equation below? Check all that apply. 4x2 - 12x + 9 = 5
Step-by-step explanation:
4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0
∆ = b² - 4ac → ∆ = (-3)² -4(1)(1) = 9 - 4 = 5
x = (-(-3) ± √5)/2(1) = (3 ± √5)/2
x² - 3x + 1 = 0 → (x - 3/2)² - 9/4 + 1 = 0 → (x - 3/2)² = 5/4 → x - 3/2 = ±√5 / 2 → x = ½( 3 ± √5)

O C. x = 0 and x = 5
O D. x = 0 and x = -5
Answer: c
Step-by-step explanation:
The zeros of the given function shown in the graph are x = 0 and x = 5. Option C is correct.
What are the zeros of equations?Zeros of an equation is defined as the value of the independent variable where the equation or function gives zero.
Here,
To calculate the zeros of a function from a graph, you need to identify the points where the graph intersects the x-axis. The x-values of these points of intersection are the zeros of the function.
Based on the graph provided, it can be concluded that the zeros of the function occur at x = 0 and x = 5, and therefore, option C is the correct answer.

Write the quadratic function in the form f (x)= a (x - h)' + k.
f (x) = 3x² - 6x+6
Answer:
[tex]f(x) = 3(x - 1)^2-3[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^2 - 6x + 6[/tex]
Required
Write as:
[tex]f(x) = a(x - h)^2 + k[/tex]
In [tex]f(x) = 3x^2 - 6x + 6[/tex], the coefficient of x is -6
Divide by 2: -3
Square: 9
Add 9 - 9 to the above equation
[tex]f(x) = 3x^2 - 6x +9-9+ 6[/tex]
Split to 2
[tex]f(x) = [3x^2 - 6x +9]-[9- 6][/tex]
[tex]f(x) = [3x^2 - 6x +9]-[3][/tex]
Factorize:
[tex]f(x) = [3x^2 - 3x -3x+9]-[3][/tex]
[tex]f(x) = [3x(x - 1) -3(x-1)]-[3][/tex]
[tex]f(x) = [(3x - 3)(x-1)]-[3][/tex]
Factorize 3x - 3
[tex]f(x) = [3(x - 1)(x-1)]-[3][/tex]
[tex]f(x) = 3(x - 1)^2-[3][/tex]
[tex]f(x) = 3(x - 1)^2-3[/tex]

Sheila is moving to a new house. She rents a truck with a storage body as shown below.
All of her belongings are in boxes that each have a volume of 9 cubic feet.
How many boxes can she fit in the storage body?
Use the drop-down menus to show your solution.
Cuboid with length as 15 ft, height as 8 ft and width as 6 ft. is given. Another cuboid with length of 4 ft, height of 6 ft and width as 6 ft is cut from bottom left corner of the bigger cuboid.
The volume of the storage body is
cubic feet.
To find how many boxes Sheila can fit in the storage body, by .
Sheila can fit
boxes into the truck.
Answer:
See below
Step-by-step explanation:
Since the shape of the truck isn't given and the volume, we will make some assumptions. You can solve this problem if you have the complete one by following the same procedure. Lets assume:
Shape of Truck is Cuboid
The dimensions of the Truck is 9 by 9 by 9
First, we need to find the volume of the cuboid truck.
Volume is basically 3 dimensions multiplied together. So that would be:
Volume of Truck = 9 * 9 * 9 = 729 cubic feet
Each box has a volume of 9 cubic feet. To get number of boxes that evenly fit the truck, we would need to divide the truck's volume by volume of each box.
729/9 = 81 boxes
Solve for x

A towns population went from 40,000 to 50,000. What was the percent of change in the population?
Answer:
The percent of change in the population was of 25%.
Step-by-step explanation:
Percent change:
The percent change is given by the change multiplied by 100, and divided by the initial value.
A towns population went from 40,000 to 50,000.
Change: 50000 - 40000 = 10000
Initial value: 40000
10000*100/40000 = 25%
The percent of change in the population was of 25%.
