The slope calculations she can use to correctly show that △PQR is a right triangle are

From the question, we have the following ordered pairs that can be used in our computation:

The vertices of △PQR are at P(-2,5), Q(-1,1), and R(7,3).

This means that

P = (-2,5),

Q = (-1,1)

R = (7,3).

The slope of the points are calculated using

slope = (y₂ - y₁)/(x₂ - x₁)

So, we have

Slope of PQ = (y₂ - y₁)/(x₂ - x₁) = (1 - 5)/(-1 - (-2)) = -4

Also, we have

Slope of QR = (y₂ - y₁)/(x₂ - x₁) = (3 - 1)/(7 - (-1)) = 2/8 = 1/4

Hence, the equations are (a) and (d)

The answer choice which must be a factor of the polynomial in discuss is; (x - 1).

It follows from the vertex form equation of a parabola; f(x) = a ( x - h )² + k where the vertex of the parabola is; (h, k).

Therefore, the equation of the parabola in discuss is;

f(x) = a (x - 3.5)² + 3.

Recall that the x coordinates of the vertex, h is given by; h = (p + q) / 2

where p and q are the zeroes of the quadratic function.

Therefore, since one of the zeroes is given as; 6 ( from (6, 0) ); it follows that the second zero can be determined as follows;

3.5 = ( 6 + q ) / 2

7 = 6 + q

q = 1

Therefore, since the second zero is; 1. It follows that the associated factor as required is; ( x - 1 ).

The normal distribution based on the graph is:

a) The mean is 91.

b) The standard deviation is 1.

c) 68 % of the data values are between 90 and 92.

e) 99.7 % of the data values are between 87 and 94.

What is the normal distribution?

The standard deviation determines the width of the curve in a normal distribution, which depicts a symmetrical plot of data around its mean value.

From the graph the mean is (x¯) = 91

a) The mean is 91

and  Standard Deviation (σ)= (∑(x - x¯)²)  

= (70-91)²+ (77-91)² +(84-91)²+(91-91)²+(98-91)²+(105-91)²+(112-91)²

= 1372 / 1371

= 1.0007293946

σ = 1

b) The standard deviation is 1.

if x¯ is the mean and σ is the standard deviation of the distribution, then 68% of the values fall in the range between (x¯−σ) and (x¯+σ).

= (91 -1) (91+1)

= 90 to 92

c) 68 % of the data values are between 90 and 92.

About 95% of the values lie within two standard deviations of the mean, that is, between (x¯−2σ) and (x¯+2σ).

(91-2) to (91+2)

89 to 93

d) 95 % of the data values are between 89 and 93.

About 99.7% of the values lie within three standard deviations of the mean, that is, between (x¯−3σ) and (x¯+3σ) .

(91-3) to (91+3)

87 to 94

e) 99.7 % of the data values are between 87 and 94.

Hence, the normal distribution based on the graph is:

a) The mean is 91.

b) The standard deviation is 1.

c) 68 % of the data values are between 90 and 92.

e) 99.7 % of the data values are between 87 and 94.

GJ = LM =7

GM = 7+2+2+7 = 18!

So the answer it is 18.

The domain and the range of the function are given as follows:

The domain of a function is the set containing all the values assumed by the input of a function, hence on the graph it is given by the values of x for which the function is defined.

The range of a function is the set containing all the values assumed by the output of a function, hence on the graph it is given by the values of y which the function assumes.

In this problem, the horizontal line is given as follows:

y = -3.

Hence the lone value assumed by output is of 3, meaning that the range is given as follows:

{3}.

In {} notation because it is a single element, not an interval.

The values of x, that is, the values of the horizontal axis assumed by the function are between -3 and 3, hence the domain is given by the following interval:

[-3, 3].

Which is a closed interval due to the closed circle.

(3x-2)(4y-3)

Answer: (3x-2)(4y-3)

Step-by-step explanation:

1. An equation that finds the number of car washes for which the costs of Plan A and Plan B are the same is 12n = 16 + 8n.

2. The solution of the equation shows that the number of car washes for which the cost of each plan is the same is 4.

Equations are mathematical statements claiming that two or more mathematical expressions are equal or equivalent when solved.

Equations use numbers, constants, variables, and the equation symbol (=) to depict the equality of the mathematical expressions.

                                 Plan A     Plan B

Cost per cash wash  $12           $8

Fixed cost                  $0           $16

Mathematical Expressions for the Carwash Plans:

Let Plan A = 0 + 12n

Let Plan B = 16 + 8n

The number of car washes when the two plans' costs are equal can be derived by equating the two mathematical expressions above:

12n = 16 + 8n

12n - 8n = 16

4n = 16

n = 4

= 4 car washes

Check:

Plan A = 0 + 12n

= 12(4)

= 48

= $48

Plan B = 16 + 8n

= 16 + 8(4)

= 16 + 32

= 48

= $48

Thus, solving the equation, we can conclude that choosing Plan B will take 4 car washes to equal the cost of Plan A.

The total number of buttons they have is 4033.

A system having more than two equations is known as a system of equations.

Given that, Sebastian and Zoey had 3068 buttons, Sebastian and Valeria had 2103 buttons, and Valeria has half as many buttons as Zoey.

The equations corresponding to the statements are:

S + Z = 3068         (1)

S + V = 2103          (2)

V = Z/2                   (3)

Subtract equation (2) from equation (1):

Z - V = 965

Substitute V = Z/2 into the above equation:

Z - Z/2 = 965

Z/2 = 965

Z = 1930

Substitute Z = 1930 into equation (3):

V = 1930/2

V = 965

Substitute V = 965 into equation (2):

S + 965 = 2103

S = 1138

The total number of buttons is:
S + V + Z

= 1138 + 965 + 1930

The time it takes for the projectile to reach its maximum height would be 0.77 s. The time it takes for the projectile to hit the ground is 2.67 s.

The horizontal range ∆x would be 20.3 m.

To determine the time it takes for the projectile to reach its maximum height, we can use the formula:

t = (vi sin(θ)) / g

where t is the time, vi is the initial velocity, θ is the angle of launch, and g is the acceleration of gravity.

In this case, the initial velocity has a horizontal component of 7.5 m/s, so we can assume that the initial velocity is 7.5 m/s and the angle of launch is 90 degrees (since the projectile is launched horizontally). Therefore, the time it takes for the projectile to reach its maximum height would be:

t = (7.5 m/s × sin(90)) / 9.8 m/s2 = 0.77 s

To determine the time it takes for the projectile to hit the ground, we can use the formula:

t = (2 ∆y) / (vi sin(θ))

where t is the time, ∆y is the maximum height, vi is the initial velocity, and θ is the angle of launch.

Since we know that the projectile rises to a maximum height of ∆y above the end of the cannon's barrel, the initial velocity has a horizontal component of 7.5 m/s and the angle of launch is 90 degrees, we can calculate the time it takes for the projectile to hit the ground as follows:

t = (2 ∆y) / (7.5 m/s x sin(90)) = (2 ∆y) / 7.5 m/s = 2.67 s

To determine the horizontal range ∆x of the shot, we can use the formula:

∆x = (vi × t) cos(θ)

where ∆x is the horizontal range, vi is the initial velocity, t is the time, and θ is the angle of launch.

In this case, we know that the initial velocity has a horizontal component of 7.5 m/s, the time it takes for the projectile to hit the ground is 2.67 s, and the angle of launch is 90 degrees.

Therefore, the horizontal range ∆x would be:

∆x = (7.5 m/s × 2.67 s) × cos(90) = 20.3 m.
