What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
Given:
g(x) = 2x² - 4
The above function is a quadratic function.
The solution of when g(-2):
Substituting the value of x = -2
g(x) = 2x² - 4
g(x) = 2(-2)² - 4
g(x) = 8 - 4

Motorcycle travel 90 mph accelerates to pass a truck five seconds later the car is going 120 mph calculate the acceleration
Answer:
Explanation:
Let Vc be the velocity of the car and I'm the velocity of the motorcycle. If we convert their given values, we get:
Vc = 87 km/h * 1000m / 1km * 1h / 3600s = 24.17m/s
Vm = 95 km/h * 1000m / 1km * 1h / 3600s = 26.38m/s
Since their positions are equal after 17s we can stablish that:
Where d is the initial separation distance of 54m. Solving for a, we get:

Write as many equations as possible that could represent the relationship between the ages of the two children in each family described. Be prepared to explain what each part of your equation represents. In Family A, the youngest child is 7 years younger than the oldest, who is 18
Answer:
Step-by-step explanation:
a) Here we have:
"In Family A, the youngest child is 7 years younger than the oldest, who is 18"
Let's define:
Y = age of the youngest child.
O = age of the oldest child.
Then we know that:
Y = O - 7
O = 18
Then we can replace the second equation into the first one:
Y = 18 - 7 = 11.
b) Here we have:
"In Family B, the middle child is 5 years older than the youngest child."
Let's define:
Y = age of the youngest child.
M = age of the middle child.
Here we have only one equation:
M = Y + 5.
Answer:
M = Y + 5.

The scale of a map says that 8cm represents 5km what is the actual number of kilometers that is represented by 5 centimeters on the map
Answer:
8 km
Step-by-step explanation:
It is given that, the scale of a map says that 8 cm represents 5 km. We need to find the actual number of kilometers that is represented by 5 centimeters on the map.
8 cm = 5 km
1 cm = (8/5) km
For 5 cm, multiply (8/5) km by 5.
So,
x = 8 km
So, 8 km is represented by 5 centimeters on the map.

The parabola has focus (–8, 0) and vertex at the origin
Answer:
x = -1/32y^2
Step-by-step explanation:
Since the focus is to the left of the vertex at a distance of 8 units, the equation can be written as ...
x -h = 1/(4p)(y -k)^2 . . . . with vertex-focus distance of p and vertex (h, k)
x = -1/32y^2

Alex bought home a 7 11/12 foot tree. When he got it home,he cut 1 2/3 off of it. How tall is the tree after he cut it down
Given:
Initial height of tree = [tex]7\dfrac{11}{12}[/tex] foot
He cut [tex]1\dfrac{2}{3}[/tex] off of tree.
To find:
The remaining height of tree after cut.
Solution:
Initial height of tree is
[tex]7\dfrac{11}{12}=\dfrac{7\times 12+11}{12}[/tex]
[tex]7\dfrac{11}{12}=\dfrac{84+11}{12}[/tex]
[tex]7\dfrac{11}{12}=\dfrac{95}{12}[/tex]
He cut [tex]1\dfrac{2}{3}[/tex] off of tree.
[tex]1\dfrac{2}{3}=\dfrac{1\times 3+2}{3}[/tex]
[tex]1\dfrac{2}{3}=\dfrac{3+2}{3}[/tex]
[tex]1\dfrac{2}{3}=\dfrac{5}{3}[/tex]
Now,
Remaining height = Initial height - cut
[tex]=\dfrac{95}{12}-\dfrac{5}{3}[/tex]
[tex]=\dfrac{95-20}{12}[/tex]
[tex]=\dfrac{75}{12}[/tex]
[tex]=\dfrac{25}{4}[/tex]
[tex]=\dfrac{6\times 4+1}{4}[/tex]
[tex]=6\dfrac{1}{4}[/tex]
Therefore, the remaining height of the tree is [tex]6\dfrac{1}{4}[/tex] foot.

-px+r=8x-2 slove for x
Step-by-step explanation:
-px + r = 8x -2
Step 1: Add -8x to both sides.
-px + r + -8x = 8x - 2 + -8x
-px + r - 8x = 2
Step 2: Add -r to both sides.
-px + r - 8x + -r = -2 + -r
-px - 8x = -r - 2
Step 3: Factor out variable x.
x(-p - 8) = -r - 2
Step 4: Divide both sides by -p - 8.
x(-p - 8) = -r - 2
-p - 8 -p - 8
Answer
x = r + 2
p + 8
