Perimeter = 12.5 cm

Step-by-step explanation:

    d = 7 cm

    [tex]\sf \boxed{\text{Circumference of quarter circle =$\dfrac{1}{4} \pi d$}}[/tex]

                                                       [tex]\sf = \dfrac{1}{4}*\dfrac{22}{7}*7\\\\ =\dfrac{11}{2}\\\\ = 5.5 \ cm[/tex]

The function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)

For a function to have its vertex on the y-axis, then the coordinate of the vertex must be:

(h,k) = (0,y)

A quadratic function is represented as:

f(x) = (x - h)^2 + k

So, we have:

f(x) = (x - 0)^2 + k

Evaluate

f(x) = x^2 + k

From the list of options, we have:

f(x) = (x - 2)(x + 2)

Expand

f(x) = x^2 - 4

Hence, the function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)

Answer:

I think your answer should be 26

Step-by-step explanation:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

13/3 ×6/1

I'm not positive but this is how I solved the problem:

The constant of proportionality that relates the distance traveled to the elapsed time represented by this data will be 6.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Eric conducted an experiment in his science class and recorded the data in a table.

Eric’s science experiment, time (seconds), 3, 6, 9, 12, 15, 18, distance (ft), 18, 36, 54, 72, 90, 108.

Let x be the time and y be the distance.

Let the distance and time be linear to each other. Then the linear equation is given as

y -  36 = [(36 - 18) / (6 - 3)] (x - 6)

y - 36 = 6 (x - 6)

       y = 36 + 6x - 36

       y = 6x

Then the constant of proportionality that relates the distance traveled to the elapsed time represented by this data will be 6.

Answer:

[tex]y = -\frac{1}{3}x[/tex]

Step-by-step explanation:

The scatter plot trends downward from left-> right, meaning that it is negative. Next, use two points to solve for the value for the slope.

In this case, I will use (-3 , 1) & (0 , 0)

Use the following equation. m = slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (0 , 0)\\(x_2 , y_2) = (-3 , 1)[/tex]

Plug in the corresponding numbers to the corresponding variables:

[tex]m = \frac{1 - 0}{-3 - 0} = \frac{1}{-3} = -\frac{1}{3}[/tex]

Your answer will be:

[tex]y = -\frac{1}{3}x[/tex]

Answer: 12 divided by 3 equals 4

Step-by-step explanation: this should answer your question if not, then please feel free to message me.

According to the given information, the difference between 12 and 3 is  9 and the quotient of 12 and 3 is 4. Hence, the Product of the difference and the quotient is 36.

Use the concept of multiplication defined as:

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

To find the product and quotient you mentioned,

Break it down step by step.

First, let's find the difference between 12 and 3.

The difference is the result of subtracting one number from another.  So,

12 - 3 = 9.

Next, let's find the quotient of 12 and 3.

The quotient is the result of dividing one number by another. So,

12 ÷ 3 = 4.

Finally, to get the product of the difference and the quotient,

We multiply them together.

In this case,

9x4 = 36.

Hence, the product of the difference between 12 and 3 and the quotient of 12 and 3 is 36.

Based on the calculation below, the amount of vanessa’s down payment is $9,314.45.

First, we have to calculate the balance after deducting vanessa’s down payment using the formula for calculating the present value (PV) of an ordinary annuity as follows:

PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)

Where;

PV = Present value or balance after deducting vanessa’s down payment = ?

P = Monthly payment = $1,595.85

r = Monthly interest rate = 6.25% / 12 = 0.0625 / 12 = 0.00520833333333333

n = number of months = 30 * 12 = 360

Substitute the values into equation (1), we have:

PV = $1,595.85 * ((1 - (1 / (1 + 0.00520833333333333))^360) / 0.00520833333333333) = $259,185.55

Now, the amount of vanessa’s down payment can be calculated as follows:

Vanessa’s down payment = Cost of the house – PV = $268,500 - $259,185.55 = $9,314.45

In the equation model, the simple harmonic motion is d=6sin(πt/4)-6 if the object moves in simple harmonic motion with a period of 8 seconds and amplitude of 6 cm.

Simple Harmonic Motion is described as a motion in which the restoring force is proportionate to the body's displacement from its mean position.

We have:

Amplitude A = 6 cm

Time period = 8 seconds

T = 2π/w

8 = 2π/w

w = π/4

Its displacement d from rest is -6 cm, and initially, it moves in a positive direction.

d(0) = -6 cm at t = 0

The equation becomes:

[tex]\rm d = 6sin(\dfrac{\pi}{4}t)-6[/tex]

Thus, in the equation model, the simple harmonic motion is d=6sin(πt/4)-6 if the object moves in simple harmonic motion with a period of 8 seconds and amplitude of 6 cm.
