What is the solution to the equation below? √x+3 = x-3

Mathematics
1 answer:
Greeley [361]1 year ago
3 0

Answer:

B) x = 6

Step-by-step explanation:

first, square both sides: x + 3 = x^2 - 6x + 9 (using the (a+b)^2 identity)

second, move the x + 3 to the right side to get a quadratic that equals 0: x^2 - 7x + 6 = 0

solve & factor the quadratic: (x - 6) (x - 1), so the solutions are x = 6 and x = 1

x = 1 isn't an answer, so the answer is b) x = 6

hope this helps! <3

Find the area of the following shape. Show work.
Serga [27]

Answer:

The total area:

12 units²

Step-by-step explanation:

There are three parts on this shape:

1 big right triangle

1 rectangle

1 small right triangle

  • Big right triangle:

area = (4*4)/2 = 16/2 = 8units²

  • Rectangle:

area = 2*1 = 2units²

  • Small right triangle:

area = (2*2)/2 = 2units²

  • Total area

8+2+2 = 12 units²

Find tan(450-a), If <br><img src="https://tex.z-dn.net/?f=%20%5Ctan%28a%29%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20" id="TexFormula1"
Inessa05 [86]

Answer:

tan(450-a)=5\sqrt{3}-8

Step-by-step explanation:

We know that:

tan(a-b)=\frac{tan(a)-tan(b)}{1+tan(a)tan(b)}

tan(450-a)=\frac{tan(450)-tan(a)}{1+tan(450)tan(a)}

Remember:

450°=360°+60°

and:

tan(a)=\frac{1}{2}

Thus:

tan(450-a)=\frac{tan(60)-tan(a)}{1+tan(60)tan(a)}\\\\

Then:

tan(450-a)=5\sqrt{3}-8

Inferential statistics allow you to decide whether a difference between the experimental and the control group is due to:_______
den301095 [7]

Answer:

Option (A)

Step-by-step explanation:

There are 2 main branches of statistics. They are:

1. Descriptive Statistics

2. Inferential Statistics

Descriptive statistics describes the characteristics of observed subjects or items while Inferential statistics makes inferences, based on given or derived data.

Inferential Statistics allow you to decide whether a difference between the experimental group and control group is due to <u>manipulation or chance.</u>

<u />

The Experimental group is the group that an effect is tested on while the Control group is the group that is left untested or uninfluenced. Inferential statistics allow you to decide whether a difference between these 2 groups is due to

- manipulation or interference by any force (which may be the experimenter/researcher)

or

- probability which is chance.
