Answer:

The expression 3p⁵ ₓ 8p³ / 2p can be simplified to 12p⁷.

Step-by-step explanation:

To simplify:

3p⁵ ₓ 8p³ / 2p

= (3 ₓ 8)(p⁵ ₓ p³) / 2p

= 24p⁸ / 2p

= 12p⁷

Answer:

The velocity is 8.93 meters/second.

Step-by-step explanation:

It is given that  Elena runs for 28 seconds and finishes at 250 meters.

Here the displacement is 250 meters and the time is 28 seconds.

We know that  [tex]V=\dfrac{\text{Displacement}}{\text{Time}}[/tex]

Substitute displacement = 250 and time = 28 in above formula.

[tex]V=\dfrac{250}{28}[/tex]

[tex]V\approx 8.93[/tex] meters/second

Hence, the velocity is 8.93 meters/second.

Answer: 0.796 meters

Step-by-step explanation:

Circumference of circle = [tex]2\pi r[/tex] , where r=radius

Here, Circumference of loop = 2.5 meters

i.e. [tex]2\pi r=2.5[/tex]

[tex]\Rightarrow\ r=\dfrac{2.5}{2\pi}[/tex]

[tex]\Rightarrow\ r=\dfrac{2.5}{2\times\dfrac{22}{7}}\\\\\Rightarrow\ r=\dfrac{2.5\times7}{2\times22}\\\\\Righttarrow\ r=0.398\ m[/tex]

Diameter = 2r = 2(0.398) = 0.796 meters

Hence, The diameter of Taiga's exercise hoop = 0.796 meters

Answer:

[tex]f(x) = x^{2} - 1[/tex]

Step-by-step explanation:

The definition of even function is: [tex]f(x) = f(-x)[/tex]

I am going to assume the  second option is [tex]f(x) = x^{2} - 1[/tex] and the answer.

[tex]f(x) = x^{2} - 1\\f(-x) = (-x)^{2} - 1 = x^{2}-1[/tex]

Answer:

-44 feet deep

In other words: 44 feet below ground

Step-by-step explanation:

First we have to write out the equation that the problem creates for us.

-48 - 11 + 15

Next we just have to subtract and add:

-48-11 = -59

-59+15 = 44

There we go! That's our answer.

Answer:

Area is 50 meters squared

Step-by-step explanation:

So you know that length = 10 meters and width is half of the length.

You need to make an equation to solve for width, 'W', using length, 'L'

W = L / 2

Now just plug in length

W = 10 /2 = 5

Since you know length and width now, you can solve for area

Area = W * L

Area = 5 * 10

Area = 50

Answer:

The instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] at the value [tex]x = 3[/tex] is 18.

Step-by-step explanation:

a) Geometrically speaking, the average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval by definition of secant line:

[tex]r = \frac{y(b) -y(a)}{b-a}[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds of the interval.

[tex]y(a)[/tex], [tex]y(b)[/tex] - Function exaluated at lower and upper bounds of the interval.

If we know that [tex]y = 3\cdot x^{2}[/tex], [tex]a = 3[/tex] and [tex]b = 6[/tex], then the average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval is:

[tex]r = \frac{3\cdot (6)^{2}-3\cdot (3)^{2}}{6-3}[/tex]

[tex]r = 27[/tex]

The average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval [tex][3,6][/tex] is 27.

b) The instantaneous rate of change can be determined by the following definition:

[tex]y' = \lim_{h \to 0}\frac{y(x+h)-y(x)}{h}[/tex] (2)

Where:

[tex]h[/tex] - Change rate.

[tex]y(x)[/tex], [tex]y(x+h)[/tex] - Function evaluated at [tex]x[/tex] and [tex]x+h[/tex].

If we know that [tex]x = 3[/tex] and [tex]y = 3\cdot x^{2}[/tex], then the instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] is:

[tex]y' = \lim_{h \to 0} \frac{3\cdot (x+h)^{2}-3\cdot x^{2}}{h}[/tex]

[tex]y' = 3\cdot \lim_{h \to 0} \frac{(x+h)^{2}-x^{2}}{h}[/tex]

[tex]y' = 3\cdot \lim_{h \to 0} \frac{2\cdot h\cdot x +h^{2}}{h}[/tex]

[tex]y' = 6\cdot \lim_{h \to 0} x +3\cdot \lim_{h \to 0} h[/tex]

[tex]y' = 6\cdot x[/tex]

[tex]y' = 6\cdot (3)[/tex]

[tex]y' = 18[/tex]

The instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] at the value [tex]x = 3[/tex] is 18.

Answer:

y=2x-16

Step-by-step explanation:

so gradient is 8-(-8)/ 12-4

so 16/8 which is 2

equation of line is: y= 2x+c

substitute the values into x,y

8=2(12)+c

8=24+c

8-24=c

-16= C

this is because when it goes over the equal sign it becomes negative so now the equation is y=2x-16

Answer:

Y=2x+16

Answer:

He will have 2.92 pounds of dog food left.

Step-by-step explanation: Subtract 2.83 from 5.75 and you will get this answer.. hope this helped:)!!

Answer:

2.92 pounds

Step-by-step explanation:

We are finding out how much we have left, so we're subtracting, so our equation is:

5.75 - 2.83 = 2.92

So, Julio will have 2.92 pounds of dog food left

Answer:

56.25 pound of the coffee that costs $5 per pound is needed

18.75 pound of the coffee that costs $9 per pound is needed

Step-by-step explanation:

Let the number of pounds be x and y respectively

The total pounds is 75;

So;

x + y. = 75 •••••••(i)

Total cost of first type

9 * x = $9x

Total cost of second type;

5 * y= $5y

75 pound at $6 per pound; total cost of this is;

6 * 75 = $450

Thus;

9x + 5y = 450 ••••••••(ii)

From i, x = 75-y

Put this into ii

9(75-y) + 5y = 450

675 -9y + 5y = 450

4y = 675-450

4y = 225

y = 225/4

y = 56.25

x = 75 - y from i

x = 75-56.25

x = $18.75

Answer:

Commission rate = 15%

Step-by-step explanation:

Given that:

Amount of merchandise sold = $2700

Commission earned = $405

We can find the commission rate by dividing the commission with total sales and multiplying it with 100.

Commission rate = [tex]\frac{Commission}{Total\ sales}*100[/tex]

Commission rate = [tex]\frac{405}{2700}*100[/tex]

Commission rate = 0.15 * 100

Commission rate = 15%

Hence,

Commission rate = 15%

Answer:

(4,4)

Step-by-step explanation:

There are two ways that you can solve this. You can solve it with the help of technology or you can solve it traditionally. I will show how to do it in both ways so you can pick which way you want to solve it.

Traditional Method:

5x - 2y = 12

6x + 2y = 32

Look at the variables and numbers in both equations. One of them has to be the same value but have to have opposite signs. The 2y in both equations are the same value but have different signs. That's what we want. We can add everything in the equation now. (5x + 6x), (-2y + 2y), and (12 + 32).

11x = 44

To get x alone, Divide each side by 11. Then we will get the value of x.

11/11x = 44/11

x = 4

Horray! We got x, but what about y? Pick one of the equations. I will go with 5x - 2y = 12. Substitute the x value inside the equation.

5(4) - 2y = 12

20 - 2y = 12

-2y = -8

y = 4

Good! We figured out y. Now we know the solution! The solution is (4,4).

Technology Method:

Grab a graphing calculator. Enter the equations. You will see two lines. Look at where they intersect. The point where they intersect is the solution. That line is (4,4). You could also do this on a piece of paper by graphing the equations.

I hope this helps! Let me know if you need any more help or if I got anything wrong.
