Answer:

x = -2/ 9

Step-by-step explanation:

[tex] \frac{2}{5}(x - 2) = 4x \\ \frac{5}{2} \times \frac{2}{5}(x - 2) = 4x \times \frac{5}{2} \\ x - 2 = 10x \\ 9x = - 2 \\ x = \frac{ - 2}{9} [/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

Answer:

covariance: 168.30correlation coefficient: 0.688

Step-by-step explanation:

A spreadsheet is made for this sort of computation. Copy the data to a spreadsheet. Use the "text to columns" feature to separate the data from the dates, and to put the A and B data in different columns.

Then use the spreadsheet built-in covariance and correlation functions to find the values of interest.

In the attachment, we have hidden the middle 50 rows of data to make it easier to select the range of data required for the functions we're using. (In many spreadsheets, you can name a range, so you only need to refer to it by name.)

The formulas we used are ...

  in D2: =COVAR(B2:B61,C2:C61)

  in D3: =CORREL(B2:B61,C2:C61)

Graphing calculators and spreadsheets are essential technology tools. While it can take a bit of study to learn all of the features in depth, you can usually learn enough in a few minutes to be able to make use of these tools to solve many problems. In most cases, videos are available.

The Go.ogle Sheets application works in a browser and is free. That's what was used here. Other free office-type applications (word processor, spreadsheet, and so on) are also available for download to computer, tablet, or phone. (I find it tedious to use these apps on a phone.)

If the hypotenuse of a right triangle is 6 m and the one side is 4 m, what's the length of the other side?

Answers

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

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]

(01.01 LC)An athlete took forward and backward steps of equal distance to warm up before his race. After taking 10 steps total, he was back at his starting position. How many steps did the athlete take in the forward and backward directions?

I would love the help.

Answers

9514 1404 393

Answer:

5 steps forward5 steps backward

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.

1.) Find the length of the arc of the graph x^4 = y^6 from x = 1 to x = 8.
2.) Find the length of arc with parametric equations x = 3 cos t, y = 3 sin t from t=0 to t=⛩

Answers

I believe I've addressed (1) in another question of yours (24529718).

For (2), the arc length of the curve parameterized by x(t) = 3 cos(t ) and y(t) = 3 sin(t ) over 0 ≤ t ≤ π is

[tex]\displaystyle \int_0^\pi \sqrt{\left(\frac{\mathrm dx}{\mathrm dt}\right)^2 + \left(\frac{\mathrm dy}{\mathrm dt}\right)^2}\,\mathrm dt[/tex]

We have

[tex]\dfrac{\mathrm dx}{\mathrm dt} = -3\sin(t) \text{ and }\dfrac{\mathrm dy}{\mathrm dt} = 3\cos(t)[/tex]

so that the integral reduces to

[tex]\displaystyle \int_0^\pi \sqrt{9\sin^2(t) + 9\cos^2(t)}\,\mathrm dt = 3\int_0^\pi\mathrm dt[/tex]

since [tex]\cos^2(t)+\sin^2(t)=1[/tex] for all t. The remaining integral is trivial:

[tex]\displaystyle 3\int_0^\pi\mathrm dt = 3t\bigg|_0^\pi = 3(\pi-0) = \boxed{3\pi}[/tex]

−∣2x+4∣+3= -4
Absolute Value Equation step by step

Answers

Answer:

x = -3/2

Step-by-step explanation:

- |2x + 4| + 3 = -4

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

-2x - 4 + 3 = -4

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

-2x - 1 = -4

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

-2x = -3

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

x = -3/2

Answers

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! :)
