Apply the Pythagorean Theorem here.  

Square the lengths of the 2 shorter sides:  (20 mi)^2 and (40 mi)^2.  Correct results are 400 and 1600.  Combine these:  obtain 2000.

Then the length of the diagonal (which is the distance between the 2 cities) is
sqrt(2000) = sqrt(400)*sqrt(5) = 20 sqrt(5)    (answer)

A loan for $1,200 has an annual interest rate of 5.2%. There is a $15 processing fee to receive the loan. The loan’s APR is .
Charra [1.4K]

<u>Answer: </u>

A loan for $1,200 has an annual interest rate of 5.2%. There is a $15 processing fee to receive the loan. The loan’s APR is 5.2%

<u>Solution: </u>

Since full form of APR is Annual Percentage Rate and it is defined as rate of interest for whole year which means it is same as annual interest rate. Also processing fee is totally different component.

So APR = annual interest rate ----- eqn 1

Given that a loan of $1200 has an annual interest rate of 5.2% .

So by using eqn 1 we can say APR = annual interest rate = 5.2%

Hence APR for a loan of $1200 is 5.2%

8) BRAINLIEST + 15+ POINTS! :)<br><br> Which of the following is a graph of y=1/2 x +1
LuckyWell [14K]

Answer:

D

Step-by-step explanation:

We can rule out the second and third because the y intercept in those graphs are not 1

Now lets look at the point 2,5 on graph a

y=1/2x+1

so 5=1+1 but that is false

D is the answer by elimination

How do you solve the three forms: Slope Y-intercept form Standard Form Point slope form
Nostrana [21]

Answer:An equation in the slope-intercept form is written as

y=mx+b

Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept.

Example

Find the equation of the line

Choose two points that are on the line

Calculate the slope between the two points

m=y2−y1x2−x1=(−1)−33−(−3)=−46=−23

We can find the b-value, the y-intercept, by looking at the graph

picture28

b = 1

We've got a value for m and a value for b. This gives us the linear function

y=−23x+1

In many cases the value of b is not as easily read. In those cases, or if you're uncertain whether the line actually crosses the y-axis in this particular point you can calculate b by solving the equation for b and then substituting x and y with one of your two points.

We can use the example above to illustrate this. We've got the two points (-3, 3) and (3, -1). From these two points we calculated the slope

m=−23

This gives us the equation

y=−23x+b

From this we can solve the equation for b

b=y+23x

And if we put in the values from our first point (-3, 3) we get

b=3+23⋅(−3)=3+(−2)=1

If we put in this value for b in the equation we get

y=−23x+1

which is the same equation as we got when we read the y-intercept from the graph.

To summarize how to write a linear equation using the slope-interception form you

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Once you've got both m and b you can just put them in the equation at their respective position.
