Answer:

The first thing you should do is draw the points in the Cartesian plane and then join them to find the polygon.

The searched polygon can be seen in the attached image.

The area of the polygon will be the area of the square plus the area of the triangle.

At = (6) * (8) + (1/2) * (5) * (8) = 68

At = 68

answer

the area of the polygon is 68units ^ 2

Rebecca has a credit line of $6,500. She had a previous balance of $398.64 and made a payment of $250. The total of her purchase

valentina_108 [34]

Answer:

$5093.37

Step-by-step explanation:

To get Rebecca's available credit we need to take all of her payments and purchases and previous balance.

Previous balance = $398.64

Purchases = $1,257.99

Payment = $250

Credit Line = $6,500

Now first we add together her purchases and previous balance.

398.64 + 1,257.99

This will give us:

$1,656.63 Total deductions.

Now we subtract that to her credit line.

$6500.00 - $1656.63

$4843.37

Now we take her payment and add it to her credit line.

$4843.37 + $250

$5093.37

So Rebecca's available credit is $5093.37.

Bill began his diet when he weighed 268 pounds. After 4 weeks he weighed 250 pounds. Write an equation in slope-intercept form o

Alika [10]

An equation in slope-intercept form of the line

$p=-\frac{9}{2}w+268\\$

Given :

Bill began his diet when he weighed 268 pounds.

After 4 weeks he weighed 250 pounds

Lets 'w' represents weeks and 'p' represents pounds

Using the given information ,we find two points (w,p)

Bill began his diet when he weighed 268 pounds.

when w=0 , weight in pounds =268

(0,268)

After 4 weeks he weighed 250 pounds, so point is (4,250)

Use two points to write the equation of line

Slope intercept form is y=mx+b

where m is the slope and b is the y intercept

slope formula using 2 points (0,268) and (4,250)

$m=\frac{y_2-y_1}{x_2-x_1} =\frac{250-268}{4-0} =-\frac{9}{2}$

now use slope m and any one point (0,268) to write equation

$y=mx+b\\y=-\frac{9}{2}x+b\\(0,268) where x=0 and y=268\\268=-\frac{9}{2}(0)+b\\\\b=268$

we know that w represents weeks and p represents pounds

The equation of the line in slope intercept form is

$p=-\frac{9}{2}w+268\\$

Please help!!! I’ll mark you as brainliest

Answer:

The correct answer is 17 weeks.

Step-by-step explanation:

First, write an equation:

total cost = (30)weekly + deposit

Let's solve:

1004.51 = 30w + 500

504.51 = 30w Subtract 500 from both sides

16.817 = w Divide both sides by 30

17 = w Round up (money always rounds up)

Hope this helps,

How do I solve this problem?

sammy [17]

Answer:

Step-by-step explanation:

The first 2 pieces of this function agree at pi/4, so we will set them equal to each other and sub in pi/4 for x to solve for k:

$ksin(\frac{\pi}{4})+(\frac{\pi}{4})^2=\frac{\pi}{4}+2$ and

$k(\frac{\sqrt{2} }{2})+\frac{\pi^2}{16}=\frac{\pi}{4}+2$ and we'll multiply everything by 16 to get rid of the fractions. Doing that gives us:

$8k\sqrt{2}=4\pi+32-\pi^2$ and

$k=\frac{4\pi+32-\pi^2}{8\sqrt{2} }$ so

k = 3.067

The next one is a bit tricky if you're not up on your natural log equations.

Again, we set these equal to each other because they meet at the value of e. We sub in e for x and solve for m:

$x +2=mlne^x$

We'll sub in e for x. ln of e to the x power is equal to x, so

e + 2 = me and

$m=\frac{e+2}{e}$ so

m = 1.736

Hope that helps!
