identify the amplitude of the graph

Answer:

Jasmine ran last week 37.2 miles

Step-by-step explanation:

Let

x ----> number of miles Rob ran last week

y ----> number of miles Jasmine ran last week

we know that

x=y-27.2 ----> equation A

x=10 ----> equation B

Substitute equation B in equation A and solve for y

10=y-27.2

y=10+27.2

y=37.2 miles

Answer:

([tex]\frac{17}{2}[/tex], [tex]\frac{33}{8}[/tex]

Step-by-step explanation:

Given the 2 equations

- 2x = 16 - 8y → (1)

x + 4y = 25 → (2)

Rearrange (2) expressing x in terms of y by subtracting 4y from both sides

x = 25 - 4y → (3)

Substitute x = 25 - 4y into (1)

- 2 (25 - 4y) = 16 - 8y ← distribute left side

- 50 + 8y = 16 - 8y ( add 8y to both sides )

- 50 + 16y = 16 ( add 50 to both sides )

16y = 66 ( divide both sides by 16 )

y = [tex]\frac{66}{16}[/tex] = [tex]\frac{33}{8}[/tex]

Substitute this value into (3) for corresponding value of x

x = 25 - 4 × [tex]\frac{33}{8}[/tex] )

  = [tex]\frac{50}{2}[/tex] - [tex]\frac{33}{2}[/tex] = [tex]\frac{17}{2}[/tex]

Solution is ( [tex]\frac{17}{2}[/tex], [tex]\frac{33}{8}[/tex] )

To solve the given system of equations using substitution, solve one equation for one variable and substitute that expression into the other equation. The solution to the system is x = 17 and y = 6.25.

To solve the system of equations using substitution, we need to solve one equation for one variable and substitute that expression into the other equation. Let's solve the first equation for x:

-2x = 16 - 8y

Adding 2x to both sides, we get:

0 = 16 - 8y + 2x

Now, we solve the second equation for x:

x + 4y = 25

Substituting the expression for x into the second equation, we get:

16 - 8y + 2x + 4y = 25

Simplifying the equation:

-4y + 16 + 25 = -2x + 2(25)

Combine like terms:

41 - 4y = 50 - 2x

Now, let's isolate x:

-2x = 41 - 4y - 50

Simplifying the equation:

-2x = -4y - 9

Dividing by -2, we get:

x = 2y + 4.5

Now we have the expression for x, which we can substitute into either of the original equations to find the value of y. Let's substitute it into the first equation:

-2(2y + 4.5) = 16 - 8y

Simplifying the equation:

-4y - 9 = 16 - 8y

Adding 8y to both sides:

4y - 9 = 16

Adding 9 to both sides:

4y = 25

Dividing by 4, we get:

y = 6.25

Now that we have the value of y, we can substitute it into the expression for x:

x = 2(6.25) + 4.5

Simplifying the expression:

x = 12.5 + 4.5

Simplifying further:

x = 17

So, the solution to the system of equations is x = 17 and y = 6.25.

Answer:

Step-by-step explanation:

Just to keep the computer happy by not having to figure out rounding answers that involve square roots and other problem numbers. I've chosen numbers that should work out evenly. And you should be able to draw the trapezoid.

Givens

H = 14

a = 23

b = 25

Area = 336

Formula

Area = (a + b)*h/2

Solution

Area = (23 + 25)*14/2

Area = 48 * 7

Area = 336

Note if a + b = 48 any values for a and b will work.

For the equation to work, you have to have the same number on both sides of the equal sign

so to find ?, you can do:

13 - 2 = 12 - ?       Simplify

11 = 12 - ?       Subtract 12 on both sides

-1 = - ?     Multiply -1 on both sides

1 = ?

To find the missing number in the equation 13-2=12-?, we subtract the known numbers on both sides of the equation.

To find the missing number in the equation 13-2=12-?, we subtract the known numbers on both sides of the equation.

In the equation 13-2=12-x, we need to find the missing number x.

We can solve this equation by subtracting the known numbers on both sides.

Using the concept of simple mathematics, we found the subtraction of the given number.

So the missing number in the equation 13-2=12-x is 11.

Answer: Option A

[tex]P = 5.3 + 0.09125t[/tex]

Step-by-step explanation:

Note that for the initial year, 1990, the population was 5.3 billion.

The exchange rate is 0.09125 billion per year. In other words, each year there are 0.09125 billion more people.

In year 2 there will be 0.09125 * 2 billion people

In year 3 there will be 0.09125 * 3 billion people

In year 4 there will be 0.09125 * 4 billion people

In year t there will be 0.09125 * t billion of people

So the equation that models the number of people that there will be as a function of time is:

[tex]P = P_0 + rt[/tex]

Where [tex]P_0[/tex] is the initial population

[tex]P_0 = 5.3[/tex] billion

r is the rate of increase

[tex]r = 0.09125[/tex] billion per year

finally the equation is:

[tex]P = 5.3 + 0.09125t[/tex]

The correct answer is option A.

Answer: 146 is 500% of 29.2

Step-by-step explanation:

100%/x%=29.2/146

(100/x)*x=(29.2/146)*x       - we multiply both sides of the equation by x

100=0.2*x       - we divide both sides of the equation by (0.2) to get x

100/0.2=x  

500=x  

x=500

now we have:  

146 is 500% of 29.2

For this case we propose a rule of three:

146 ----------> 100%

29.2 ---------> x

Where the variable "x" is the percentage that represents 29.2 of 146.

[tex]x = \frac {29.2 * 100} {146}\\x = \frac {2920} {146}\\x = 20[/tex]

Answer:

You can find the perpendicular bisector of MA and then plug in the point.

Step-by-step explanation:

To find the perpendicular bisector of MA, you have to go through a 4 step process.

1. Find the midpoint of MA

2. Find the slope of MA

3. Find the perpendicular slope to the slope of MA.

4. Substitute in your midpoint into the equation and solve for the y-intercept.

Plug in your point into the equation and see if it works out.

You'll have to do the actual work yourself though!

The point which satisfy the equation of line having the slope -2/3 and point (-4,1), lies on the perpendicular bisector of MA.

The perpendicular bisector on a line segment is the line which divides the line in two equal parts and intersect the line at 90 degrees.

The line segment MA has the end points as M(−2, 4) and A(−6, −2). The midpoint of this line segment is,

[tex]p=(\dfrac{-2+(-6)}{2},\dfrac{4+(-2)}{2})\\p=(\dfrac{-8}{2},\dfrac{2}{2})\\\\p=(-4,1)[/tex]

The slope of this line segment MA is,

[tex]m=\dfrac{-2-4}{-6-(-2)}\\m=\dfrac{-6}{-4}\\m=\dfrac{3}{2}[/tex]

The slope of MA is 3/2. Thus, the slope of a line segment which is perpendicular to this is -2/3.

Thus, the point which satisfy the equation of line having the slope -2/3 and point (-4,1), lies on the perpendicular bisector of MA.
