Mathematics
1 answer:
Masja [62]3 years ago
5 0

Answer:

b. 10

Step-by-step explanation:

Based on the Pythagoras Theorem, the longest side of a right-angled triangle is: \sqrt{a^{2}+b^{2} } where a and b are the legs of the triangle.

Longest side of triangle = \sqrt{8^{2}+6^{2}}

                                        = \sqrt{64+36}

                                        = \sqrt{100}

                                        = 10

If your current examination mean is 97.2 and you receive a 99 on the next examination, what effect will this have?
mr Goodwill [35]

If you have an average of 97.2 on your current exam and you get a 99 on your next exam, your average will increase.

  • Mean in mathematics is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the total number of values.

  • To find the average, sum all the values ​​in the set. Then divide the total by the number of values.

We have the current examination mean, xold = 97.2

Now, we receive,  x = 99 on the next examination, the new mean will be:

xnew = (xold + x)/N

xnew = (97.2+99)/2

xnew = 196.2/2

xnew = 98.1  

The new average is 98.1

98.1 > 97.2

So if you score 99 on your next exam, your average will increase.

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Factoring
  • Quadratic Formula: \displaystyle x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

<u>Algebra II</u>

  • Imaginary Numbers: √-1 = i

Step-by-step explanation:

<u>Step 1: Define</u>

x² + 2x = -2

<u>Step 2: Identify Variables</u>

  1. Rewrite Quadratic in Standard Form [Addition Property of Equality]:        x² + 2x + 2 = 0
  2. Break up Quadratic:                                                                                        a = 1, b = 2, c = 2

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [Quadratic Formula]:                                                \displaystyle x=\frac{-2 \pm \sqrt{2^2-4(1)(2)}}{2(1)}
  2. [√Radical] Evaluate exponents:                                                                     \displaystyle x=\frac{-2 \pm \sqrt{4-4(1)(2)}}{2(1)}
  3. Multiply:                                                                                                           \displaystyle x=\frac{-2 \pm \sqrt{4-8}}{2}
  4. [√Radical] Subtract:                                                                                        \displaystyle x=\frac{-2 \pm \sqrt{-4}}{2}
  5. [√Radical] Factor:                                                                                        \displaystyle x=\frac{-2 \pm \sqrt{-1}\sqrt{4}}{2}
  6. [√Radicals] Simplify:                                                                                       \displaystyle x=\frac{-2 \pm 2i}{2}
  7. Factor:                                                                                                             \displaystyle x=\frac{2(-1 \pm i)}{2}
  8. Divide:                                                                                                             \displaystyle x = -1 \pm i
