Answer:

  -4u^2/y+(5/2)y^3u^2

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

__

  (8y^2u^7-5y^6u^7)\div(-2y^3u^5)=\dfrac{8y^2u^7-5y^6u^7}{-2y^3u^5}\\\\=-4y^{2-3}u^{7-5}+\dfrac{5}{2}y^{6-3}u^{7-5}=\boxed{\dfrac{-4u^2}{y}+\dfrac{5}{2}y^3u^2}

Pls help answering a b and c
Anastasy [175]

Answer:

a) The very first one where the line starts to the left

b) m=125.82

c) 320.81 thousand dollars

Step-by-step explanation:

a) The point on the graph who corresponds to x=3 years and Salary=$200,000 is the very first one where the line starts to the left

b) If a line is given by Y=mx+b, m represents the slope of the line. In this case, m=125.82 which can be interpreted as the rate of growth of the salary per year in thousands of dollars. A doctor can expect to earn 125.82 thousand dollars more than the previous year.

c) If we use the given regression line Y=125.82x-182.47 and make x=4, we get

y=125.82 (4)-182.47 =320.81 thousand dollars

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Leg <em>a</em> = <em>x</em>

Leg <em>b</em> = 2

Hypotenuse <em>c</em> = 7

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    x² + 2² = 7²
  2. Isolate <em>x </em>term:                      x² = 7² - 2²
  3. Exponents:                          x² = 49 - 4
  4. Subtract:                              x² = 45
  5. Isolate <em>x</em>:                              x = 3√5
  6. Evaluate:                              x = 6.7082
  7. Round:                                 x ≈ 6.7

Create an equation for the following scenario:
Ivanshal [37]

Hey there! I'm happy to help!

Sum means you add. Let's call our number n.

n+15

We double the whole thing.

2(n+15)

This is equal to something.

2(n+15)=

Difference means you subtract.

2(n+15)=n-6.

Have a wonderful day! :D
