Answer:

  -25

Step-by-step explanation:

Consult your memory of multiplication tables to determine the square root of 100.

  10×10 = 100

  √100 = 10

Then multiply that value by -2.5

  -2.5×10 = -25

___

Of course, you can use a calculator or spreadsheet to evaluate this expression, too.

Step-by-step explanation:

g(x) = x² + 3

g(-5) = (-5)² + 3

g(-5) = 25 + 3

g(-5) = 28

Answer:

Function 2, because Ricky spends $7 each week and Tony spends $6 each week

Step-by-step explanation:

You find the rate of weekly rate of change by calculating the difference of the amount changing each week:

24 - 30 = - 6

18 - 24  = - 6

12 - 18 = - 6

As you see the rate of change is constant: - 6 dollars per week. This means that Tony is spending 6 dollars every week

Function 2: y = –7x + 30  

The rate of change is the slope (m) of the linear function, and this is the coefficient of the independent variable, x.

This equation is written in slope intercept form (y= mx+b)

Then the rate of change is - 7 dollar per week. This means Ricky spends 7 dollars every week.

Now you know that the two rates are constant and that the second function shows a steeper decreasing.

Step-by-step explanation:

α = α

x = 96°

Answer → x = 96° (degree)

Answer:

96 Degrees

Step-by-step explanation:

If we look at the problem, we know that due to the fact that they are adjacent that they MUST be equal.

Here is the proof:

We'll assign each angle a letter as following

A B C D with A being the top left and D being the bottom right!

Now that we know that, first off, A has to be equal to 180-96 due to them being Supplementary Angles.

Therefore, A is 84 degrees.

Now to find x, we can use Supplementary Angles again.

x has to be 180-84 which is 96 degrees proving the theorum.

Have a nice day!

Answer:

9

Step-by-step explanation:

You choose the middle one because 3<(4)<10 makes sense where as the other ones don't when you plug in 4. Then you solve the equation which is x^2-7 and then you get 16-7 which is 9.

Answer:

d. 14% of increase

Step-by-step explanation:

0.32 to 0.37 = increase

0.37 - 0.32 = 0.05

What percentage is 0.05 of 0.37

X/100 = 0.05/0.37

(0.05 * 100)/0.37

X = 13.51 = 14%

Answer:

The answer is 100.

Step-by-step explanation:

I started with solving 4 divided by 5. It was 0.8. I then started going thru 1 to 10 to 20 to 50 to 100. I was comparing big numbers. I then realized 100+0.8 times 100 = 180!

Answer: [tex]x=100[/tex]

If the equation is [tex]x+\frac45 x = 180[/tex] we add on the LHS: [tex]x(1+\frac45) = 180 \rightarrow x(\frac55+\frac45)= 180\\\frac95 x = 180[/tex]

At this point we divide both sides by 9 and multiply by 5:

[tex]x=\frac 59 (180) = \frac59 (2\times 9 \times 10) = 100[/tex]

Answer:

iI think the answer is 9

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

A quadratic is 'involving the second and no higher power of an unknown quantity or variable.'

Therefore, we can exclude b and d easily because both have a higher power of 2. 9x^(2) is not a binomial because it only has 1 term (i think its called a term) leaving A, x^2-16x as the only answer left.

Answer:

18

Step-by-step explanation:

[tex]\sqrt{((-2)^2 + 12)} + 14[/tex]

= [tex]\sqrt{(4 + 12)} + 14[/tex]

= [tex]\sqrt{16}+14[/tex]

= 4 + 14

= 18

Answer:

[tex] \sf 18[/tex]

Step-by-step explanation:

[tex] \sf = \sqrt{ { - 2}^{2} + 12} + |14| [/tex]

[tex] \sf = \sqrt{(( - 2) \times ( - 2)) + 12} + 14[/tex]

[tex] \sf = \sqrt{4 + 12} + 14[/tex]

[tex] \sf = \sqrt{16} + 14[/tex]

[tex] \sf = \sqrt{ {4}^{2} } + 14[/tex]

[tex] \sf = 4 + 14[/tex]

[tex] \sf = 18[/tex]
