[tex]\sqrt(12-8x)=x-3[/tex]

Answers

Answer 1

Answer:

x = -3 and x = 1

Step-by-step explanation:

first, square each side

12 - 8x = x² - 6x + 9

x² + 2x - 3 = 0

(x - 1)(x + 3) = 0

x = -3

x = 1

Answer:

196

Step-by-step explanation:

Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor. So in the case of 32, it can be written as 2 × 2 × 2 × 2 × 2=25, where 2 is the “base” and 5 is the “exponent”. We read this expression as “two to the fifth power”.

Given:

[tex](\sin x)^2+(\cos x)^2=1[/tex]

[tex]\cos \theta = \dfrac{4\sqrt{2}}{7}[/tex]

To find:

The value of [tex]\sin \theta[/tex].

Solution:

We have,

[tex]\cos \theta = \dfrac{4\sqrt{2}}{7}[/tex]

Putting this value in the Pythagorean identity, we get

[tex](\sin \theta)^2+(\cos \theta)^2=1[/tex]

[tex](\sin \theta)^2+\left(\dfrac{4\sqrt{2}}{7}\right)^2=1[/tex]

[tex](\sin \theta)^2+\dfrac{16(2)}{49}=1[/tex]

[tex](\sin \theta)^2+\dfrac{32}{49}=1[/tex]

[tex](\sin \theta)^2=1-\dfrac{32}{49}[/tex]

[tex](\sin \theta)^2=\dfrac{49-32}{49}[/tex]

[tex](\sin \theta)^2=\dfrac{17}{49}[/tex]

Taking square root on both sides, we get

[tex]\sin \theta=\pm \sqrt{\dfrac{17}{49}}[/tex]

[tex]\sin \theta=\pm \dfrac{\sqrt{17}}{7}[/tex]

The given value of [tex]\sin \theta[/tex] is positive. So, [tex]\sin \theta= \dfrac{\sqrt{17}}{7}[/tex].

Therefore, the value of value [tex]\sin \theta[/tex] is [tex]\sin \theta= \dfrac{\sqrt{17}}{7}[/tex].

What is the unknown side length, p, in the triangle shown below? ​

Answers

Answer:

9

Step-by-step explanation:

To solve this, you need to find the proportion.

p is a leg of the large triangle, and the leg to the small triangle is 6.

8 is another leg of the small triangle, and 8+4 is the leg of the large triangle.

So [tex]\frac{small triangle}{big triangle} = \frac{small triangle}{big triangle\\}[/tex]

[tex]\frac{8}{12} =\frac{6}{p}[/tex]

[tex]\frac{2}{3} =\frac{6}{p}[/tex]

cross multiply to get 2p=18

divide both sides by 2

p=9.

A health club manager wants to determine whether the members would prefer a new sauna or a new steam room. The club surveys 50 of its 600 members. What is the population of this study? The population is all 50 members of the health club. The population is all 600 and 50 members of the health club. The population is all 600 members of the health club. The population is all 30,000 members of the health club.

Answers

Answer:

The population is all 600 members of the health club

Explanation:

50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.

Answers

Answer:

Step-by-step explanation:

4) Angles opposite to equal sides are equal

45 + 45 + x = 180     {Angle sum property}

        90 +x = 180       {Subtract 90 from both sides}

               x = 180 - 90  

               x = 90

120 +y + y = 180        {Angle sum property}

      120 +2y = 180       {Subtract 120 from both sides

              2y =180 - 120

               2y = 60      {Divide both sides by 2}

                 y = 60/2

y = 30

5)All sides are equal. so this is a equilateral triangle.

So each angle of equilateral triangle = 60

4x = 60

x = 60/4

x = 15

y = 60 +60   {Exterior of triangle equal sum of opposite interior angles}

y = 120

6) All sides are equal. so this is a equilateral triangle.

So each angle of equilateral triangle = 60

y - 10 = 60    {add 10 to both side}

y = 60 + 10

y = 70

x + 5 = 60    {Subtract 5 from both sides}

x = 60 - 5

x = 55
