Answer:

the problem is asking you to divide (16-2) by (7-5)

14 / 2

The answer is 7

Step-by-step explanation:

The expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 is (16-2)/(7-5) and the solution of this equation is 7.

Quotient is the resultant number which is obtained by dividing a number with another. Let a number is divided by number b. Then the quotient of these two number will be,

\(q=\dfrac{a}{b}\)

Here, (a, b) are the real numbers.

The expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 has to be written.

Let n, is the required expression. Thus,

\(n=\dfrac{16-2}{7-5}\)

Solve it further,

\(n=\dfrac{14}{2}\\n=7\)

Thus, the expression for the calculation of the quotient of 16 minus 2 and 7 minus 5 is (16-2)/(7-5) and the solution of this equation is 7.

slope of y = x - 18

slope: 1

y-intercept: y = x - 18

y= 0 - 18= -18

y-int: (0, -18)

Answer:

y = (5/7)x + (75/7)

Step-by-step explanation:

If you ever find yourself in a math class where you have to write the equation of a line that goes through a certain point and has a certain slope, don't panic. There is a simple formula that can help you out. It's called the point-slope form and it looks like this:

y - y1 = m (x - x1)

It may look scary, but it's actually pretty easy to use. All you have to do is plug in the values that you know and solve for the ones that you don't. For example, let's say you have a line that passes through the point (-1, 10) and has a slope of 5/7. You can use the point-slope form to write the equation of the line like this:

y - 10 = (5/7) (x - (-1))

See? That wasn't so bad. Now you can simplify the equation by distributing the 5/7 and adding 10 to both sides. You get:

y = (5/7)x + (75/7)

And that's it! You have written the equation of the line in slope-intercept form, which is another way of writing the equation of a line. You can check your answer by plugging in the values of x and y from the original point and seeing if they make the equation true. If they do, you're good to go. If not, you made a mistake somewhere and you should go back and fix it.

Congratulations! You have learned how to use the point-slope form to write the equation of a line. Now you can impress your math teacher and your friends with your skills.  Remember, with great power comes great responsibility.

Step-by-step explanation:

If you look at the centerand radius of a circle (those are the two most important things when defining a circle), you will see, they shrank by a factor of two, so since it affected both x and y, it had to be from the origin.

If Q is an orthogonal matrix with an eigenvalue λ1 = 1, then x, the eigenvector corresponding to λ1, is also an eigenvector of QT with an eigenvalue λ2 = λ1 * (QT * x).

To show that x is also an eigenvector of QT, we need to demonstrate that QT * x is a scalar multiple of x.

Given that Q is an orthogonal matrix, we know that QT * Q = I, where I is the identity matrix. This implies that Q * QT = I as well.

Let's denote x as the eigenvector corresponding to the eigenvalue λ1 This means that Q * x = λ1 * x.

Now, let's consider QT * x. We can multiply both sides of the equation Q * x = λ1 * x by QT:

QT * (Q * x) = QT * (λ1 * x)

Applying the associative property of matrix multiplication, we have:

(QT * Q) * x = λ1 * (QT * x)

Using the fact that Q * QT = I, we can simplify further:

I * x = λ1 * (QT * x)

Since I * x equals x, we have:

x = λ1 * (QT * x)

Now, notice that λ1 * (QT * x) is a scalar multiple of x, where the scalar is λ1. Therefore, we can rewrite the equation as:

x = λ2 * x

where λ2 = λ1 * (QT * x).

This shows that x is indeed an eigenvector of QT, with the eigenvalue λ2 = λ1 * (QT * x).

In conclusion, if Q is an orthogonal matrix with an eigenvalue λ1 = 1, then x, the eigenvector corresponding to λ1, is also an eigenvector of QT with an eigenvalue λ2 = λ1 * (QT * x).

The true statement is that the difference between the maximum profit earned by the sandwich shop and the smoothie stand is $2,700. (option d).

To determine the maximum profit earned by each business, we need to find the vertex of each quadratic function. The vertex of a quadratic function of the form ax² + bx + c is given by the formula (-b/2a, f(-b/2a)), where f(-b/2a) is the maximum value of the function.

The equations for the two functions are:

f(x) = -500x² + 9000x + 7500 g(x) = -500x² + 7500x + 4200

To find the vertex of f(x), we need to first rewrite the function in standard form:

f(x) = -500(x² - 18x - 15)

Completing the square, we get:

f(x) = -500(x - 9)² + 12000

So the vertex of f(x) is (9, 12000), which represents the maximum profit earned by the sandwich shop.

Similarly, to find the vertex of g(x), we rewrite the function in standard form:

g(x) = -500(x² - 15x - 8.4)

Completing the square, we get:

g(x) = -500(x - 7.5)² + 14100

So the vertex of g(x) is (7.5, 14100), which represents the maximum profit earned by the smoothie stand.

Finally, we can calculate the difference between the maximum profits earned by both businesses as:

12000 - 14100 = -2700

Therefore, the correct answer is option (d).

Answer:

Therefore, the angle ∠CDA is 58°.

Step-by-step explanation:

∠CDA = 58°

In the given figure, let's consider the angle ∠CDA as x.

Since AB is the diameter of the circle, we know that the angle subtended by any diameter at any point on the circumference is always 90°. Therefore, ∠CAB = 90°.

In triangle CAD, the sum of angles is 180°. So, we have:

∠CAD + ∠CDA + ∠CAB = 180°

Substituting the known values:

32° + x + 90° = 180°

Combining like terms:

x + 122° = 180°

Subtracting 122° from both sides:

x = 180° - 122°

The average rate of change over is 1.

Given that;

the function is,

⇒ g (t) = - (t - 1)² + 5

Hence, We need to determine the average rate of change over the interval - 4 ≤ t ≤ 5.

The value of G(-4):

The value of G(-4) can be determined by substituting t = -4 in the function

⇒ g (t) = - (t - 1)² + 5

Thus, we have,

⇒ g (t) = - (-4 - 1)² + 5

⇒ g (t) = - 20

Thus, the value of G(-4) = -20

The value of G(5):

The value of G(5) can be determined by substituting t = 5 in the function , we get,

⇒ g (t) = - (t - 1)² + 5

⇒ g (t) = - (5 - 1)² + 5

⇒ g (t) = - 11

Thus, the value of G(5) is, -11

Now, Average rate of change:

The average rate of change can be determined using the formula,

⇒ G(b) - G (a) / (b - a)

where, a = - 4 and b = 5

Substituting the values, we get,

⇒ G(5) - G (-4) / (5 - (-4))

⇒ ( - 11 - (- 20)) / 9

⇒ 9/9

⇒ 1

Thus, the average rate of change over the interval is. 1.

The angle sum property of a triangle and the angle formed between a tangent and a radius of a circle indicates.

m∠ADC = 58°

A tangent to a circle is a straight line which touches the circumference of a circle at only one point.

The vertical angles theorem indicates that we get;

∠1 ≅ ∠2

Therefore; m∠1 = m∠2

The tangent to a circle indicates that we get;

The angle formed at vertex B and Q are 90 degrees angles and the triangles ABP and AQP are right triangles, which indicates that the acute angles of each of the right triangles are complementary, therefore;

m∠1 + 26° = 90°

m∠1 = 90° - 26° = 64°

Therefore, m∠2 = m∠1 = 64°

m∠2 = m∠CAD = 64°

The segments AC and AD are radial lengths therefore, the triangle ΔACD is an isosceles triangle.

m∠ADC ≅ m∠ACD (Base angles of an isosceles triangle)

The angles ∠ADC and ∠ACD are therefore;

m∠CAD + m∠ADC + m∠ACD = 180° (Angle sum property of a triangle)

m∠CAD + m∠ADC + m∠ADC = 180°

m∠CAD + 2 × m∠ADC = 180°

64° + 2 × m∠ADC = 180°

1) The period of the given function is \(2\pi\).

2) Golfer has to originally hit the ball 343.1326 yards for it to go directly to the same position on the green.

1)The function satisfying the given table will be:

\(f(x) = 2Cos(\frac{\pi }{2} +x) +1\)

or \(f(x) = -2Sinx +1\)

The period of the function is the minimum value of the dependent variable x after which the function will repeat itself.

For example, Sin x = Sin(2π + x)

So, 2π will be the period of the function.

Suppose the period of the given function is k

So, f(x+k) = f(x)

\(-2Sin(k+x) +1 = -2Sin x+1\)

\(Sin (k+x) = Sin x\\Sin (k+x) = Sin (2\pi +x)\)

\(k+x = 2\pi +x\)

\(k =2\pi\)

So the period of the given function is \(2\pi\).

2) Consider the first hit as the side AB of a triangle, the second hit as the adjacent side to the first side i.e BC of a triangle. So, angle B will be equal to 100 degrees.

In order to originally hit the ball for it to go directly to the same position on the green we need to calculate AC

So, from the cosine rule

\(Cos B = \frac{AB^{2} +BC^{2}-AC^{2} }{2.AB.BC}\)

AB =270

BC =170

B= 100°

\(Cos 100 = \frac{270^{2} +170^{2}-AC^{2} }{2.270.170}\)

AC = 343.1326 yards
