Which expresses this solution?
The equation that expresses the solution to the quadratic equation x² - 10x + 13 = 0 is [tex]x =5 \pm 2\sqrt{3}[/tex]
How to express the solution?The equation is given as:
x² - 10x + 13 = 0
The solution to a quadratic equation is represented by:
[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
So, we have:
[tex]x =\frac{10 \pm \sqrt{(-10)^2 -4 * 1 * 13}}{2 * 1}[/tex]
Evaluate the radicand
[tex]x =\frac{10 \pm \sqrt{48}}{2}[/tex]
Take the square root of 48
[tex]x =\frac{10 \pm 4\sqrt{3}}{2}[/tex]
Divide
[tex]x =5 \pm 2\sqrt{3}[/tex]
Hence, the equation that expresses the solution to the quadratic equation x² - 10x + 13 = 0 is [tex]x =5 \pm 2\sqrt{3}[/tex]

an airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph what is its average speed for the total trip?
The average speed is the ratio of the total distance to the total time. Then the average speed of the airplane will be 698.19 miles per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
An airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph.
Then time taken for the first trip will be
t₁ = 867 / 612
t₁ = 1.4167 hours
Then time taken for the second trip will be
t₂ = 1984 / 744
t₂ = 2.6667 hours
Then the average speed is the ratio of the total distance to the total time.
The total distance will be
Total distance = 867 + 1984
Total distance = 2851 miles
The total time will be
Total distance = 1.4167 + 2.6667
Total distance = 4.0834 hours
Then the average speed will be
Average speed = 2851 / 4.0834
Average speed = 698.19 mi/h

Answer:
B. The equation of the linear function is y = 3x + 2
D. The rate of change of the linear function is 3.
Step-by-step explanation:
First find the slope by choosing two ordered pairs and using the slope formula:
[tex]\textsf{let}\:(x_1,y_1)=(2,8)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(3,11)[/tex]
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{11-8}{3-2}=3[/tex]
Now use the Point-slope form of linear equation with the found slope and one of the points to create the equation of the linear function:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]\implies y-8=3(x-2)[/tex]
[tex]\implies y=3x + 2[/tex]
The rate of change of a linear function is its slope.
Therefore,
B. The equation of the linear function is y = 3x + 2
D. The rate of change of the linear function is 3.

The height of the tree is 50 feet.
We have given,
cap A tree standing vertically on level ground casts a. 72feet.
We solve this by using trigonometry, the height of the tree to the nearest foot is 50 feets
What is the tan ratio?[tex]tan\theta = opposite / Adjacent[/tex]
Opposite = height, h
Adjacent, = 140 feets
Angle, θ = 19.8°
[tex]tan(19.8) = h / 140[/tex]
Cross multiply
[tex]h = 140 \times tan(19.8)[/tex]
h = 50.403 feets
Height, h = 50 feets (nearest foot)

What is the equation of the quadratic function with a vertex at (2,–25) and an x-intercept at (7,0)? f(x) = (x – 2)(x – 7) f(x) = (x 2)(x 7) f(x) = (x – 3)(x 7) f(x) = (x 3)(x – 7)
The quadratic equation with the given characteristics is:
f(x) = (x + 3)*(x - 7).
How to get the quadratic equation?We know that the vertex must be (2, -25) and it passes through (7, 0).
For a quadratic equation:
y = a*x^2 + b*x +c
The x-value of the vertex is:
x = -b/2a
Then we have:
2 = -b/2a
We also have:
-25 = a*4 + b*2 + c
And because the function passes through (7, 0) we know that 7 is one of the roots, then:
0 = a*49 + b*7 + c
Then we have 3 equations to work with:
2 = -b/2a
-25 = a*4 + b*2 + c
0 = a*49 + b*7 + c
If we subtract the third and second equations we get:
25 = a*45 + b*5
Now, with the first equation we can rewrite:
a = -b/4
Replacing that in the other equation:
25 = a*45 + b*5
25 = (-b/4)*45 + b*5 = b*(-25/4)
25*(-4/25) =b = -4
Now we know the value of b.
2 = -(-4)/2a
a = 1
Now we need to find the value of c, we have that:
0 = 1*49 + -4*7 + c
0 = 49 - 28 + c
0 = 21 + c
Then c = -21
The equation is:
[tex]y = x^2 - 4x - 21[/tex]
It can be factorized to:
f(x) = (x + 3)*(x - 7).
