Solve for x with the given measures

Answer:

5 seconds

Step-by-step explanation:

d = vt + 16t² , that is

vt + 16t² = d

substitute d = 480, v = 16 into the equation

16t + 16t² = 480 ( divide through by 16 )

t + t² = 30 ( subtract 30 from both sides )

t² + t - 30 = 0 ← in standard form

(t + 6)(t - 5) = 0 ← in factored form

equate each factor to zero and solve for t

t + 6 = 0 ⇒ t = - 6

t - 5 = 0 ⇒ t = 5

t > 0 , then t = 5

the object will hit the ground 5 seconds later

Answer:

-------------------------

As per given we have:

Substitute these into given equation and solve for t:

The first value of t is discarded as time can't be negative, so the answer is 5 seconds.

The average hourly wage for police officers is $30.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

The U.S. Bureau of Labor Statistics is a government agency that collects information about jobs in the U.S.

In 2018, the Bureau reported that Wisconsin police officers had a mean yearly salary of $62,040.

Assume that police officers generally work 40 hours a week.

There are 52 weeks in the year.

The average hourly wage for police officers is,

= 62040 ÷ (52 x 40)

= 62040 / 2080

= 29.8

≈ $30

Therefore, $30 is the hourly wage.

Step-by-step explanation: Question 2 shows a right angle that is equal to 90 degrees. Since you are already given 34, you just need to subtract 90-34.

Question 4 shows an 180 degree angle and so you need to do the same thing; 180-124

Answer:

Chebyshev's inequality states that for any given dataset, at least 1 - 1/k^2 of the data will lie within k standard deviations from the mean.

When k = 3, at least 1 - 1/3^2 = 1 - 1/9 = 8/9 of the data will lie within 3 standard deviations from the mean.

So, for the temperature data, we can determine that at least 8/9 of the data will lie between 28.8 - 3 × 7.4 = 7°F and 28.8 + 3 × 7.4 = 50.6°F.

In other words, we can say that at least 8/9 of the temperatures recorded during the two months were between 7°F and 50.6°F.

The equation of the rational function with the given features is given as follows:

F(x) = [4(x² + 5x + 4)]/(x² - x - 6).

A rational function is a fraction, in which both the numerator and the denominator contain instances of the variable x.

Considering the x-intercepts, the numerator of the function is defined as follows:

y = a(x + 4)(x + 1)

y = a(x² + 5x + 4).

Considering the y-intercept at (0,4), the leading coefficient a is given as follows:

a = 4.

The vertical asymptotes determine the zeros of the denominator, which is given as follows:

(x + 2)(x - 3) = x² - x - 6.

Hence the function is defined as follows:

F(x) = [4(x² + 5x + 4)]/(x² - x - 6).

Answer: I do not have the capability to create a graph. However, I can tell you how to graph the parabola h(x) = -x^2 + 3.

A parabola is defined by its equation in the form y = ax^2 + bx + c, where a, b, and c are constants. In this case, a = -1, b = 0, and c = 3.

The vertex of the parabola is the highest or lowest point on the graph and is given by the coordinates (-b/2a, c - b^2/4a). For this parabola, the vertex is (0, 3), since b = 0 and a = -1.

To find another point on the parabola, you can plug in any x-value and use the equation of the parabola to find the corresponding y-value. For example, if you plug in x = -2, you get:

h(-2) = -(-2)^2 + 3

h(-2) = 4 + 3

h(-2) = 7

So the point (-2, 7) is also on the parabola.

With the vertex and one other point on the parabola, you can now graph the parabola.

  20 cubic yards

Step-by-step explanation:

You want to know the volume in cubic yards of a layer of topsoil that is 6 inches deep over an area 31 feet by 34 feet.

You know that ...

Then the dimensions of the volume being applied are ...

  6 inches = 6/36 yards

  31 feet = 31/3 yards

  34 feet = 34/3 yards

The volume is the product of the dimensions of the space:

  V = LWH

  V = (31/3 yd)(34/3 yd)(6/36 yd) ≈ 19.519 yd³

About 20 cubic yards are needed to fill the garden.

2nd choice  y = 1/2x - 5

Step-by-step explanation:

y = 1/2x - 5  is the only function listed that if you graph it, it makes a straight line.   A linear function forms a straight line when it is plotted on a graph.

The first and last choices are number values of x.

The 3rd choice, if you graph it, makes a parabola.

Answer:

Second option:

[tex]y = \dfrac{1}{2}x -5[/tex]

Step-by-step explanation:

A linear function should have y as a function of x (or x as a function of y) and the degree of the function (the highest power has to be 1)

Both x and y must be present to make it a linear function

General slope intercept form is y = mx + b where m = slope, b = y-intercept

With these restrictions the second option is the correct one
[tex]y = \dfrac{1}{2}x -5[/tex]

This line is in slope intercept form y = mx + b where m = slope(in this case 1/2) and y-intercept b(in this cae -5)

Option 1:  x = 3 is a straight vertical line parallel to the y-axis. Such a line has a slope of ∞

Option 3 is a function with degree 2 and is a quadratic function

Option 4 : 3x - 6 = 4==> 3x = 6 + 4 = 10 or x = 10/3, again another vertical line with slope = ∞

What is quadratic equation?

it's a second-degree quadratic equation which is an algebraic equation in x. Ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the quadratic equation in its standard form. A non-zero term (a 0) for the coefficient of x2 is a prerequisite for an equation to be a quadratic equation. The x2 term is written first, then the x term, and finally the constant term is written when constructing a quadratic equation in standard form. In most cases, the numerical values of letters a, b, and c are expressed as integral values rather than fractions or decimals.

The given equation y  = 25t - 1.86t²

at t =  1

So the displacement y = 25-1.86 = 23.14

to find velocity dy/dt = 25- 2(1.86)t

v = 25 - 3.72 = 21.28m/s

Hence the displacement is 23.14m and velocity is 21.28m/s

2·x + 6·y = 10

(b) Length of each Plan A workout: 1.25 hours

Length of each Plan B workout: 1.25 hours

A linear system of equation consists of two or more linear equations that share common variables.

(a) The number of Plan A workouts Mary trained on Wednesday = 5

Number of Plan B workouts she trained on Wednesday = 3

The total time (in hours) Mary trained both workouts on Wednesday = 10

Where x represents the length (in hours) of each of the Plan A workout, and B represents the time in hours of each of the Plan B workout, we get;

5·x + 3·y = 10

Similarly, the number of Plan A workouts trained on Thursday = 2

Number of Plan B workout trained on Thursday = 6

The duration of training of all workouts on Thursday = 10 hours

Therefore, we get;

2·x + 6·y = 10

The system of equations that could be used to find the length (in hours) of each type of workout can be presented as follows;

(b) The first equation from the system of equations indicates that we get;

5·x + 3·y = 10

3·y = 10 - 5·x

Plugging the value of y above into the second equation from the system of equations, we get;

2·x + 6·y = 10

2·x + 6 × ((10 - 5·x)/3) = 10

2·x + 2·(10 - 5·x) = 10

2·x + 20 - 10·x = 10
