Find the distance between (-12, 1) and (12, -1) *

Answers

Answer:

[tex]d = 2\sqrt{145}[/tex]

Step-by-step explanation:

Use the Distance Formula to help you determine the distance between the two following points ( [tex](-12, 1)[/tex] and [tex](12, -1)[/tex] ):

-Distance Formula:

[tex]d = \sqrt{(x_{2} - x_{1}) ^2 + (y_{2} - y_{1})^2}[/tex]

(where [tex]( x_{1}, y_{1})[/tex] represents the first point, and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the following points to the equation:

[tex]d = \sqrt{(12 + 12) ^2 + (-1 - 1)^2}[/tex]

[tex]( x_{1}, y_{1})[/tex] = [tex](-12, 1)[/tex]

[tex](x_{2}, y_{2})[/tex] = [tex](12, -1)[/tex]

-Solve the equation:

[tex]d = \sqrt{(12 + 12) ^2 + (-1 - 1)^2}[/tex]

[tex]d = \sqrt{(24)^2 + (-2)^2}[/tex]

[tex]d = \sqrt{576 + 4}[/tex]

[tex]d = \sqrt{580}[/tex]

[tex]d = 2\sqrt{145}[/tex]

Therefore, the distance is [tex]2\sqrt{145}[/tex].

Tom worked 48 hours last week and gets time-and-a-half pay for overtime. His regular pay is $32 per hour. a) How much does he make for an hour of overtime?

Answers

Answer:

$48

Step-by-step explanation:

From the question we know that;

His regular pay is $32 per hour.

Tom worked 48 hours last week and gets time-and-a-half pay for overtime.

Time and a half pay = 1.5

Hence, if Tom works for an hour of overtime, his pay for his overtime is calculated as:

= 1.5 × $32 × 1

= $48

Therefore, he was paid $48 for one hour of overtime.

One number is 13 more than the product of 9 and another number. If the sum of the two numbers is 103, find the two numbers.

Answers

Answer:

x + y = 103 Subtract 2nd from 1st EQ

-10y = -90

y = 9 and x = 94 9%2A9%2B13

and...checking

sum = 103

Step-by-step explanation:

The two numbers are 9 and 94.

What are simultaneous equations?

In mathematics, a set of simultaneous equation, also known as a system of equations or an equation system, is a set of equations for which common solutions are sought.

Let the two numbers be x and y.

Then according to question,One number is 13 more than the product of 9 and another number we have ,

13 + 9x = y  

or,9x - y = -13...(i)

Also,the sum of the two numbers is 103. So we have,

x + y = 103 ...(ii)

Adding equation (i) and (ii) we get,

10x = 90

or, x = 9

Put the value of x in equation (ii), we get

9 + y = 103

or, y = 103 - 9

or, y = 94

Hence the two numbers are 9 and 94.

Answers

Answer:

4h

Step-by-step explanation:

We are expected to solve for the change given the following values of x

0,h

so we substitute x= 0 and x=h in the given expression, get the result, and subtract the results from each other

for x=0

[tex]g(x) = 4 x + 7\\\\g(0)=4(0)+7\\\\g(0)=0+7\\\\g(0)=7[/tex]

 

for x=h

[tex]g(x) = 4 x + 7\\\\ g(h)=4(0)+7 \\\\g(h)=4h+7 \\\\g(h)=4h+7[/tex]

The change would be

[tex]g(h)-g(0)= (4h+7)-7\\\\g(h)-g(0)= 4h+7-7\\\\g(h)-g(0)= 4h[/tex]
