Answer:

To convert m into km we divide a number by 1000

Step-by-step explanation:

To convert from metres to kilometres, divide by 1000 (since there are 1000 metres in each kilometre). To divide a whole number by 1000, put a decimal point at the end of the number and then move it three places to the left.

Answer:

Step-by-step explanation:

In order for the total displacement to be zero, the amount of forward displacement must be equal and opposite to the amount of backward displacement. Since the steps are the same length, they must be equal in number.

Half of the 10 steps were forward, and the other half were backward.

  5 steps forward; 5 steps backward.

Additional comment

Math develops from an effort to model the real world. It would probably give you some insight into this problem if you were to physically take some steps to see how many forward and backward you would need to end where you start.

We have to find derivative of t

[tex]\\ \sf\longmapsto \dfrac{d}{dx}3t^2-12t+4[/tex]

[tex]\boxed{\sf \dfrac{d(x^n)}{dx}=nx^{n-1}}[/tex]

[tex]\\ \sf\longmapsto \dfrac{d}{dx}3t^2-\dfrac{d}{dx}12t+\dfrac{d}{dx}40[/tex]

[tex]\\ \sf\longmapsto 6t-12[/tex]

Now

[tex]\\ \sf\longmapsto 6(8)-12[/tex]

[tex]\\ \sf\longmapsto 48-12[/tex]

Over [9, 49], the average rate of change of g(x) is

[tex]\dfrac{g(49) - g(9)}{49 - 9} = \dfrac{14 - 6}{49 - 9} = \dfrac8{40} = \boxed{\dfrac15}[/tex]

Over [25, 81], it would be

[tex]\dfrac{g(81) - g(25)}{81 - 25} = \dfrac{18 - 10}{81 - 25} = \dfrac8{56} = \boxed{\dfrac17}[/tex]

Step-by-step explanation:

Answer:

7x + 2 = 9x - 1

7x - 9x = -1 - 2

-2x = -3

2x = 3

x = 3/2

Answer:

x = -3/2

Step-by-step explanation:

Remove the absolute value, since you can't solve anything inside. Everything becomes negative due to the negative sign on the outside.

Combine -4 + 3, which results in -1.

Move -1 over to the other side through adding, which results in -3.

Divide -2 by -3, which doesn't go equally, so you leave it.

Go as far as you need for an answer, all will work.

Answer:

5/12

Step-by-step explanation:

1/2 is equivalent to 6/12

1/3 is equivalent to 4/12

The number halfway between 6/12 and 4/12 is 5/12.

Answer:

5/12

Step-by-step explanation:

First we want to have common denominators, and since some of our answers are in twelfths anyways, we might as well go straight to those instead of multiplying to get common denominators of sixths.

Make the denominators of the two fractions we are given into twelfths

(-multiply 1/2 by 6 on the top and bottom to get 6/12, and multiply 1/3 by 4 on the top and bottom to get 4/12.

5/12 is perfectly halway between 6/12 and 4/12 so we have our answer! :)

Answer:

The number of cubic feet of water needed to fill the tank is [tex]216 \mathrm{ft}^{3}$[/tex]

The number of cubic yards of water needed to fill the tank is [tex]8 \mathrm{yd}^{3}[/tex]

Step-by-step explanation:

Given

A tank is in the shape of a cube with edge lengths of 6 feet.

Step 1 of 2

The volume of a cube with edge length [tex]$e$[/tex] is given by:

[tex]V=e^{3}[/tex]

Given that [tex]$e=6 \mathrm{ft}$[/tex], the number of cubic feet of water needed to fill the tank is:

[tex]V=6^{3}[/tex]

[tex]V=216 \mathrm{ft}^{3}[/tex]

Step 2 of 2

The number of cubic yards of water needed to fill the tank is

[tex]V=216 \mathrm{ft}^{3} \times \frac{(1 \mathrm{yd})^{3}}{(3 \mathrm{ft})^{3}}[/tex]

[tex]=8 \mathrm{yd}^{3}[/tex]

Answer:

a and b are and C is not. b is called an exponential function and a is another function that I forgot the name of.

Answer:

Step-by-step explanation:

This is verified with a vertical line test.

If a graph of a function is intersected by a vertical line at more than one point, it is not a function. This comes from the definition of a function.

We can see that the graphs a and c pass the vertical line test but the graph b fails, since at any positive x, the vertical line has two - y coordinates per each x- coordinate.

Answer:

400

Step-by-step explanation:

To find the scale factor, you need to find out how much the initial value was multiplied by to get the new value. To do that, you need to divide the new value by the initial value. Make sure the units are the same; don't divide 1000 feet by 30 inches!

[tex]\frac{new}{initial} = \frac{12000}{30}=400[/tex]

Hope this helps!

In general, the difference quotient is [tex]\dfrac{f(x+h)-f(x)}{h}[/tex].

Before we evaluate all of that, we need to find the two top pieces individually.

     [tex]\begin{aligned}\\f(x+h) &= -5(x+h)+8 \\[0.5em]&= -5x-5h+8\\\end{aligned}[/tex]

and

    [tex]f(x) = -5x+8[/tex]

We'll plug that back into the difference quotient:

    [tex]\begin{aligned}\dfrac{f(x+h)-f(x)}{h} &= \dfrac{(-5x-5h+8)-(-5x+8)}{h}\\[0.7em]&= \dfrac{-5x-5h+8+5x-8}{h}\end{aligned}[/tex]

Run is the difference in x-coordinates:

The slope is rise/run:

Step-by-step explanation:

We can use the Pythagorean theorem to solve for side b:

[tex]c^2 = a^2 + b^2 \Rightarrow b^2 = c^2 - a^2[/tex]

or

[tex]b = \sqrt{c^2 - a^2} = \sqrt{(6\:\text{m})^2 - (4\:\text{m})^2}[/tex]

[tex]\:\:\:\:= 4.47\:\text{m}[/tex]

Answer: 2√5 or 4.47213595

Step-by-step explanation:

Use the Pythagorean Theorem: a^2 + b^2 = c^2  

(a and b are the measures of the legs and c is the measure of the hypotenuse.)

Let's solve for a (the length of the other leg)  

*I hope that m is not a variable and just an abbreviation for meters.

b = 4 m  

c = 6 m

a^2 + 4^2 = 6^2

a^2 + 16 = 36

a^2 = √20

a = 2√5 = 4.47213595
