Use the distance formula to find the perimeter. Round to the nearest tenth.
Answer:
37.6 units
Step-by-step explanation:
Perimeter = sum of all sides of the triangle
To find the sum, find the distance between each points.
✔️Distance between points (-7, 6) and (5, -4):
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = [/tex]
[tex] = \sqrt{(5 - (-7))^2 + (-4 - 6)^2} [/tex]
[tex] = \sqrt{(12)^2 + (-10)^2} [/tex]
[tex] = \sqrt{144 + 100} [/tex]
[tex] = \sqrt{244} = 15.6 units [/tex] (nearest tenth)
✔️Distance between (-7, 6) and (-7, -4):
|6 -(-4)| = 10 units
✔️Distance between (-7, -4) and (5, -4)
|-7 - 5| = 12 units
✔️ Perimeter = 15.6 + 10 + 12 = 37.6 units
Solving Equations with Rational Exponents
Solve and check. Show all work,
write an equation for a line that passes through (-2,1) with a slope of 2/3
Answer the question above
Answer:
[tex]tan\:\left(\frac{5\pi }{6}\right)=tan\left(-\frac{\pi }{6}\right)[/tex]
Option A is correct.
Step-by-step explanation:
We need to find equivalent of [tex]tan\:\left(\frac{5\pi }{6}\right)[/tex]
First we solve [tex]tan\:\left(\frac{5\pi }{6}\right)[/tex]
We get [tex]-\frac{1}{\sqrt{3} }[/tex]
Now checking all the options.
Option A: [tex]tan\:(-\frac{\pi}{6} )[/tex]
Solving [tex]tan\left(-\frac{\pi }{6}\right)\: we\: get\: \mathbf{ -\frac{1}{\sqrt{3} }}[/tex]
Option B: [tex]tan\left(\frac{7\pi }{6}\right)[/tex]
Solving [tex]tan\left(\frac{7\pi }{6}\right)\: we\: get\: \mathbf{\frac{1}{\sqrt{3} }}[/tex]
Option C: [tex]cot\left(\frac{5\pi }{6}\right)[/tex]
Solving [tex]cot\left(\frac{5\pi }{6}\right)\:we\:get\:\mathbf{-\sqrt{3} }[/tex]
Option D : [tex]tan\left(-\frac{5\pi }{6}\right)[/tex]
Solving [tex]tan\left(-\frac{5\pi }{6}\right) \:we\:get:\mathbf{\frac{1}{\sqrt{3} } }[/tex]
So, looking at the options, only Option A has the same result as given question
So, [tex]tan\:\left(\frac{5\pi }{6}\right)=tan\left(-\frac{\pi }{6}\right)[/tex]
Option A is correct.

Answer:
0.7
Step-by-step explanation: I used a calculator.
Amr recorded the outdoor temperature as -4 degrees Fahrenheit at 7:30 A.M. At noon, it was 22 degrees Fahrenheit. Sal said the temperature changed by 18 degrees Fahrenheit because 22 - 4 = 18
(My answer is 26 for this question.)
What was the total temperature change from 7:30 A.M until noon? Use the thermometer to help justify your solution.
Answer:
26
Step-by-step explanation:
so it changed by 26 degrees because it goes -3 -2 -1 0 and then add 22 so it is 26 i think
The total temperature change would be 26 degrees from 7:30 A.M until noon.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.
We have been given that
At 7:30 A.M.,
The temperature was -4 degrees Fahrenheit
At noon,
The temperature was 22 degrees Fahrenheit
To determine the temperature change.
Here the temperature change is difference between the final temperature and initial temperature, so we have to apply the subtraction operation.
So the temperature change = 22 - (-4) = 22 + 4 = 26
Therefore, the total temperature change would be 26 degrees from 7:30 A.M until noon.

Answer:
Hours Amounts ($)1 12.04
2 24.08
3 36.12
4 48.16
5 60.20
Step-by-step explanation:
Given,
For every 5 hours money Andre gets is = $60.20
So,
For every 1 hour = $60.20 ÷ 5 = $12.04
For every 2 hours = $12.04 × 2 = $24.08
For every 3 hours = $12.04 × 3 = $36.12
For every 4 hours = $12.04 × 4 = $48.16
which values of x make 3x+4>5(x+2) true?
x<-6
x<2
x>-6
x>2
Answer:
x<-6
Step-by-step explanation:
3x+4>5(x+2)
Distribute
3x+4 > 5x+10
Subtract 3x from each side
3x+4 -3x> 5x-3x+10
4 > 2x+10
Subtract 10 from each side
4-10 > 2x+10-10
-6 > 2x
Divide each side by 3
-6/2 > 2x/2
-3 > x
Since x must be less than -3 the only statement that would be true is x< -6

Answer:
sorry, dont speak spanish
Step-by-step explanation:
A line is graphed below.
Write an equation in the form y = mx + b that represents this line
[tex]y = mx + b \\ m = slope \\ b = y - intercept[/tex]
Calculate the slope with two given coordinate by using rise over run.[tex] \begin{cases}(x_1,y_1) = ( - 4,0) \\ (x_2,y_2) = ( 0,2) \end{cases}[/tex]
These two coordinate points are part of the graph and can be used to find the slope.
[tex]m = \frac{y_2 -y_1 }{x_2 - x_1} [/tex]
Substitute the coordinate points in the formula.
[tex]m = \frac{2 - 0}{0 - ( - 4)} \\ m = \frac{2}{ 4} \\ m = \frac{1}{2} [/tex]
Therefore, the slope is 2.
Rewrite the equation in slope-intercept.
[tex]y = \frac{1}{2} x + b[/tex]
Calculate the y-intercept by substituting any given points in new rewritten equation.[tex](x,y) = ( 0,2)[/tex]
I will be substituting these coordinate points in the equation.
[tex]y = \frac{1}{2} x + b[/tex]
Substitute x = 0 and y = 5 in the equation.
[tex]2 = \frac{1}{2} (0) + b \\ 2 = 0 + b \\ 2 = b[/tex]
Therefore the y-intercept is (0,2).
Rewrite the equation.
[tex]y = \frac{1}{2} x + 2[/tex]
Answer[tex] \large \boxed{y = \frac{1}{2} x + 2}[/tex]
