The equation 3x²-5x-5 will have two solutions.

If the value of x in the given quadratic equation is a real number then the roots of the equation are real.

The discriminant of the equation will be calculated as:-

    =  3x  ²-  5x   -   5

D  =  b²   -   4ac

D  =  ( 5 )²  -   4  x  3  x  -5

D  =  25    -    ( -60 )

D  =   85

Since the discriminant is positive then the equation will have real roots and the degree of the equation is 2 so it will have two solutions.

The equation that expresses the solution to the quadratic equation x² - 10x + 13 = 0 is [tex]x =5 \pm 2\sqrt{3}[/tex]

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]

The quadratic equation with the given characteristics is:

f(x) = (x + 3)*(x - 7).

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).

Step-by-step explanation:

The tank is at its full capacity, and its full capacity is 20 gallons. This means there is 20 gallons of gas in the tank.

1) Diagonals of a rectangle bisect each other, so AW=13.

2) Since diagonals of a rectangle are congruent, AC=BD. Then, since diagonals of a rectangle bisect each other, DW=13.

3) Diagonals of a rectangle are congruent, so BD=26.

4) Opposite sides of a rectangle are congruent, so AD=10.

5) Using the Pythagorean theorem, BA=24.

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

[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)

The gross wages of Xavier Brown when worked 43.5 hours in the week will be Gross pay=$730.625

The total amount earned by any worker with his basic pay like incentives allowances etc.

It is given that Xavier Brown works on a 40-hour week basis and-a-half paid for overtime work.

Last week she worked 43.5

The distribution of the work is given as:-

Monday      Tuesday        Wed      Thursday       Friday    Total

9 Hours     9 Hours          8.5         8.5                   8.5      43.5

So we have the total working hours = 43.5 hours

Weekly working hours are =40 hours

So for 40 hours she will be paid:-

Pay =40x17.50

Now extra hours or overtime is =43.5-40=3.5 hours

So the extra income will be half of the regular:-

Pay=3.5x({1}÷{2}) x17.5=$30.625

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.

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
