The parabola in the figure below has an equation of the form
y = ax^2 + bx - 4.
Find the equation of the parabola
Answer:
y = - x² + 5x - 4
Step-by-step explanation:
Given that the zeros are x = 1 and x = 4 , then the corresponding factors are
(x - 1) and (x - 4) , then
y = a(x - 1)(x - 4) ← a is a multiplier
= a(x² - 5x + 4)
To find a substitute the coordinates of any other point on the parabola into the equation.
Using (2, 2), then
2 = a(4 - 10 + 4) = - 2a ( divide both sides by - 2 )
a = - 1
Thus
y = - (x² - 5x + 4) = - x² + 5x - 4 ( with a = - 1 and b = 5 )

which is 1/3 - 1/6 in a fraction
Answer:
Step-by-step explanation:
1/3 - 1/6
2/6 -1/6= 1/6
find common denominator
For [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .
Given to us,
[tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]
To solve this, firstly we need to make the denominators the same, thus taking the LCM of both 3 and 6.
As we know the LCM of 3 and 6 is 6 itself.
So, multiplying and dividing by 2.
[tex]\dfrac{1}{3}\rightarrow \dfrac{1\times 2}{3\times 2}\rightarrow \dfrac{2}{6}[/tex]
Now,
[tex]\dfrac{2}{6}-\dfrac{1}{6} = \dfrac{1}{6}[/tex]
Hence, for [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .

i’ll give u brainliest!! what is the area of shape 1 2 and 3
Answer:
Shape 1: 197.04
Shape 2: 125.44
Shape 3: 62.72
Step-by-step explanation:
For shape 1, you first need to find the radius to then find the area of a circle. Which is 394.08. Since this isn't a full circle, you will need to divide it by 2 to get 197.04. For shape 2(Easiest to find) You do 11.2*11.2 to get the answer of 125.44. And lastly for shape 3, you can basically do the same as what you did for shape 2. But since it is a triangle, you divide your answer by 2, to get the answer of 62.72.

A traffic engineer records a sample of the types of vehicles that cross a bridge. She counts 112 passenger cars, 18 light trucks, and 20 heavy trucks.
What is the APPROXIMATE probability that a random vehicle crossing the bridge is a passenger car?
Answer:
The approximate probability that a random vehicle is a passenger car is 74.67%
Step-by-step explanation:
Probability
The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.
We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:
[tex]\displaystyle p=\frac{112}{150}[/tex]
p = 0.7467
p = 74.67%
The approximate probability that a random vehicle is a passenger car is 74.67%

Evaluate the function:
f(x)=x2−4x, find f(−3)
Answer:
f(-3) = 21
Step-by-step explanation:
To solve this, you can replace all x's with -3 and then solve to find the answer.
f(x) = x^2 - 4x
f(-3) = -3^2 - 4(-3)
f(-3) = 9 - (-12)
f(-3) = 21

Let f(x)=e^x and g(x)=x+6. What is the domain and range of (GoF) (x)?
Answer:
Domain: Al real values
Range: All real numbers
Step-by-step explanation:
Let f(x)=e^x and g(x)=x+6. What is the domain and range of (GoF) (x)?
Given the functions'
f(x)=e^x and g(x)=x+6.
gof(x) = g(f(x))
g(f(x)) = g(e^x)
Substitute x with e^x in g(x) as shown:
g(f(x)) = e^x + 6
The domain s the input value of x for which the function exists. Accordinf to the expression, x exists on all real values. Since x exists on all real values, hence the output f(x) also exists on all real values

In a system of two linear equations, the lines represented by each equation have the same slope. Which could be the total number of solutions to the system of equation
Answer:
Please see explanation
Step-by-step explanation:
A system of linear equations in two variables represents two lines on graph.
When both the lines have same slope, there can be two cases
Same slope with different y-interceptsWhen two lines have same slope and different y-intercepts, that means that both lines are parallel and parallel lines have no solution.
Same slope with same y-interceptsWhen the slope of both lines is same and the y-intercept is also same, this means that both the equations refer to the same line. This means that the system has infinite number of solutions.

Problem 1: 1/64x^8
Problem 2: y^8/9x^2
Step-by-step explanation:
In the first problem, you first need to multiply the -2 exponent to everything in the parenthesis. This is equal to 1/64x^4*-2, simplified to be 1/64x^-8. Finally you simplify the x to 1/64x^8.
For the second problem, you do the same in the first one, getting x^-2/9y^4*-2. This can be simplified to be 3x^-2/y^-8. Finally you make sure there is no negative exponents, so you do y^8/9x^2.
Answer:
1/64x^8 and y^8/9x^2
