Because it’s 3 dimensional

Answer:6

Step-by-step explanation:

Answer: A is the correct answer .

Start with the last two choices .

You have x+ 5 and × - 5 in the square root .

A square root can never be negative .

That means that the lowest value of y can have in the last two choices is 0 .

Now range doesn't include -4.

Now look at choice B .

sqrt (x) is at least 0.

Then you add 5 .

The range doesn't include -4.

Now look at choice A .

sqrt (x) is at lest 0 .

Now ,you subract 5 .

The lowest value y can have is -5 . That includes -4.

Choice A is the answer .

y will be at least 5

Hope it works out !

Hey there!

To find our answer, we need to set up a system of equations. Remember, supplementary angles equal 180 degrees when combined. We will call one of our angles A and the other one B. Let's set it up below! :)

A=2B-15 (one angle is 15 degrees less than twice the other)

A+B=180

We need to find one of our variables. To do this, we only put one variable in the equation. But how, there are two variables in both equations! Well, as you can see, we see the A is equal to 2B-15, so we can take 2B-15 and put it into the second equation in place of A because it is equal to A, and then we will only have Bs and we can solve for it. This method is known as solving systems of equations with substitution.

Let's solve with substitution!

2B-15+B=180

3B-15=180              We combine our Bs.

3B=195              We add 15 to both sides.

B= 65                We divide both sides by three.

Now, we need to find what A is, but this will be really easy to do! If you remember, our angles are supplementary, so when you combine them, we will get 180, as you can see in our second equation in our first system of equations. So, we simply subtract 65 from 180.

180-65=115

Our two angles are 65° and 115°.

We can also check this with the original problem.

If you double 65, we have 130. Then, if we subtract 15, we have 115. Systems of equations are a pretty awesome way to figure this out!

I hope this helps! Have a great day!

Answer:

Take a look at explanation below;

Step-by-step explanation:

See attachment( s ) below;

The value of x and y angles on the given lines are x=35 degrees and y=125 degrees.

A line is a collection of points which joins the two points on the surface.

If we consider the angles which are linear pair, we found that

55 +y=180 because they are on a straight line.

From the figure wee found that x+55+90=180 because they are on a straight line.

solving the second equation we will get , x=180-145=35

solving the first equation we will get , y=180-55=125.

Hence the value of x angle is 35 degrees and the value of y angle is 125 degrees.

Step-by-step explanation:

The common difference in the arithmetic sequence is 2.5

Arithmetic sequence is a sequence in which the differences between consecutive terms are always same.

Example : 2, 5, 8, 11, ..... is an arithmetic sequence where the common difference is 3.

Formula of arithmetic sequence is [tex]a_{n} =a_{1}+(n-1)d[/tex] ,

where [tex]a_{n}[/tex]= [tex]n^{th}[/tex] term in the sequence,

[tex]a_{1}[/tex]= [tex]1^{st}[/tex] term in the sequence,

d = common difference between terms

Given, [tex]a_{1}[/tex] = 16 and [tex]a_{9}[/tex] = 36

Let, d be the common difference.

∴ From the formula of arithmetic sequence,

   [tex]a_{9} =a_{1}+(9-1)d[/tex]

⇒ 36 = 16+8d

⇒ 36-16=8d

⇒ 20=8d

⇒ d = 20/8

⇒ d = 5/2 = 2.5

Hence, The common difference is 2.5

Answer:

B. 33.6 cm

Step-by-step explanation:

To find determine the length of an arc that subtends an angle of 2.8 radians at the centre of a circle with radius 12 cm, we will follow the steps below;

First write down the formula for calculating length of an arc

If the angle is measured in degree, then the formula for calculating the length of an arc is :

length of an arc = Ф/360  ×  2πr

but if the angle is measured in radians, then the formula for calculating length of an arc will be:

length of an arc = r Ф

where r is the radius    and Ф is the central angle in radians

In the case of the question given to us, the angle is given in radians, so we will use the second formula

angle Ф = 2.8

radius = 12 cm

length of an arc = r Ф

                           =12 × 2.8

                           =33.6

Length of the arc = 33.6 cm

Step-by-step explanation:

5 12 13 triple

Answer:

r =5

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

The legs are r and 12

The hypotenuse is (8+r)

r^2 + 12^2 = (8+r)^2

r^2 + 144 = 64 + r^2 +16r

Subtract r^2 from each side

144 = 64 +16r

Subtract 64 from each side

144-64 = 16r

80 = 16r

Divide each side by 16

80/16 = 16r/16

5 =r

Answer: 8.3

Step-by-step explanation:

To find the variance, you want to find the mean of the data.

[tex]\frac{3+3+8+1+9+6}{6} =5[/tex]

Now that we have the mean, we find the difference between each data point and the mean.

3-5=-2

3-5=-2

8-5=3

1-5=-4

9-5=4

6-5=1

With the difference, you square each and find the average.

(-2)²=4

(-2)²=4

3²=9

(-4)²=16

4²=16

1²=1

[tex]\frac{4+4+9+16+16+1}{6} =\frac{25}{3}[/tex]

The variance is 8.3.
