Mathematics

Svetlanka [38]2 years ago
4 0

Answer:

2  2/3

Step-by-step explanation:

-2 1/3 - ( - 5)

We are subtracting a negative which is like adding

-2 1/3 + (  5)

The signs are different so we subtract and take the sign of the larger

5 - 2 1/3

Borr from the 5

4 3/3 - 2 1/3

2 2/3

The sign of the larger was positive so the answer is positive

2 2/3

Describe the behavior of the graph at the x-intercepts for the function f(x)=(2x-7)^7(x+3)^4. Identify each x-intercept and just
Shkiper50 [21]

Answer:

f(x)=(2x-7)^7(x+3)^4

When y=0, (2x-7)^7=0 and x=3.5 OR

(x+3)^4=0, and x=-3

Look at x=h or f(2)

That is 96-56-44+2 and it is not equal to 0. (x-2) is not a factor.

x^3-5x^2+6x-30

after trying 1,2, and 3, I tried 5

5/1===-5===6===-30

==1===0====6====30

(x^2-6) with no remainder

the factors are (x-5)(x^2+6)

the zeroes are 5, +/- i sqrt (6). Only one real 0.

hope this helps let me know in the comments if i'm wrong

Andrea recorded the points she scored in her last eight basketball games. What is the mean absolute deviation of the scores
grandymaker [24]
The mean absolute deviation is a measure of variability in statistics.  This number tells us how close the rest of the numbers are to the mean.  The closer they are to the mean, the more reliable the data is.

The attached work shows how to find the MAD (mean absolute deviation).

Here are the steps:
1.  Find the mean of the data.  2.  Find the difference between the mean and the data values. 3.  Find the average of these differences.

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio
Iteru [2.4K]

The simplification form of the provided expression is 6/5x¹⁰ option first is correct.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

\rm = \sqrt{\dfrac{72x^{16}}{50x^{36}}}

\rm = \sqrt{\dfrac{72}{50}} \sqrt{\dfrac{x^{36}}{x^{16}}}

\rm = \sqrt{\dfrac{36\times2}{25\times2}} \sqrt{\dfrac{x^{36}}{x^{16}}}

\rm ={\dfrac{6x^{8}}{5x^{18}}}

\rm ={\dfrac{6}{5x^{10}}}

Thus, the simplification form of the provided expression is 6/5x¹⁰ option first is correct.
