Answer:

y = -2x + 18

Step-by-step explanation:

Slope m = -2 with y = 8, x = 5

y = mx + b

8 = (-2)(5) + b

8 = -10 + b

b = 8 + 10 = 18

then y = -2x + 18

The range of a data set in statistics is the difference between the largest and the smallest values. While range does have different meanings within different areas of statistics and mathematics, this is its most basic definition, and is what is used by the provided calculator. Using the same example:

2,10,21,23,23,38,38

38 - 2 = 36

The range in this example is 36. Similar to the mean, range can be significantly affected by extremely large or small values. Using the same example as previously:

2,10,21,23,23,38,38,1027892

The range, in this case, would be 1,027,890 compared to 36 in the previous case. As such, it is important to extensively analyze data sets to ensure that outliers are accounted for.

Answer: Range is all the values of the y-axis therefore, the range of the graph is {0,4,6,8}

Answer:

  19 seconds

Step-by-step explanation:

You want to know the time it takes for Juan, running 18 m/s, to overtake Mahdi, running 6 m/s, if Mahdi has a 228 meter head start.

The time to close the gap between the runners will be ...

  time = distance/speed

  time = (228 m)/(difference in speeds) = (228 m)/(18 m/s -6 m/s)

  time = (228 m)/(12 m/s) = (228/12) s = 19 s

It will take Juan 19 seconds to catch Mahdi.

The entire area filled by a triangle's three sides on a two-dimensional plane is referred to as the triangle's area. The fundamental equation for a triangle's area is A = 1/2 b h, where b and h are the product of the triangle's base and height. All triangle shapes, including scalene, isosceles, and equilateral triangles, may be calculated using this formula. It is important to keep in mind that a triangle's base and height are perpendicular to one another.

Area of triangle SXY = 1/2 × SX × (x-2);

Area of triangle STR = 1/2 × ST × (x+3);

Area of trapezium XTRY = 1/2 × (x+3+x-2) × XT;

Area of triangle SXY = Area of triangle STR - Area of trapezium XTRY;

SX × (x-2) = ST × (x+3) - (2x + 1) × XT;

As; SX = TX = ST/2;

(x-2)/2 = (x+3) - (2x+1)/2;

x - 2 = 2x + 6 -2x -1

Answer: Answer  2, Triangle A is dilated from the origin by a scale of 1/2 to obtain triangle B

Step-by-step explanation:

The domain is:

D: {-4, 5, 6, 8}

The range is:

R: {-4, 3, 5}

And yes, the relation is a function.

For a relation that maps elements x into elements y (in the form (x, y)), we define the domain as the set of the inputs (values of x) and the range as the set of the outputs (values of y).

Here our relation is defined by: {(6,3), (8,5), (-4,-4), (5,5)}

The domain is the set of the first values of each pair, so we have:

D: {-4, 5, 6, 8}

The range is the set of the second values of each pair:

R: {-4, 3, 5}

Now, is this a function?

Yes, it is a function, because each input is mapped into only one output.

The conditional statement is that; If generally a person is 1% shorter in the evening than in the morning, then my height is about 1.62326 m in the evening.

First, we will calculate how much is one percent of your height and then subtract that percentage from the total height to get your" height in the evening".

For example:

If my height is 1.64 m, then;

0.01 * 1.64 m = 0.0164 m

Step 2 is;

1.64m - 0.0164m = 1.62326 m

Explanation:

Place the decimal point between the first two digits to get 5.0

Then we must move the decimal point 4 spots to the right to get back to 50,000

So that's where the "4" comes in with the 10^4

This means 50,000 = 5 * 10^4 which is in scientific notation.

The answer in scientific notation is 5 times 10^4

The exponent of four tells you to multiply 10 by itself 4 times.

10 x 10 = 100 x 10 = 1000 x 10 = 10000

And 10000 times 5 is equal to 50,000.

The length of the side of Amy’s printed picture is 6 inches.

A square is a two-dimensional closed shape with four equal sides.

Now, as per the given question;

The original length of the side of the square was 4 inches.

Thus, the area of the old photo was;

A = side²

A = 4²

A = 16 square inch.

Now, as the picture is increased by 225%.

Then, increase the area by 225%.

New area = 225% of old area

                = (16×225)/100

New area = 36

The length of the side of the new photograph is;

New area = length²

length = √New area

The distance between the starting point(initial) and the ending point(last) is known as displacement is  9.46miles.

What is displacement?

In the first(1st) part of the race displacement of Erica is

d1 = 5.2 miles at 25(twenty-five) deg North of East

x(ax) and y-component of 1st(first) part of the race will be:

d1 = 5.2*cos 25(twenty five) deg i + 5.2*sin 25(twenty five) deg j

d1 = (4.71 i + 2.20 j) miles (this id d1)

In the second(2nd) part of the race

d2 = 6(six) miles towards north,

So

d2 = (6 j) miles (this is d2)

Now net(accurate) displacement of Erica will be, Using Vector addition(summation):

d = d1(4.71 i + 2.20 j) + d2(6j)

d = (4.71 i + 2.20 j) +(sum) (6 j)

d = 4.71 i +(sum) 8.20 j

So Magnitude of net(accurate) displacement will be:

|d| = [tex]\sqrt{4.71^2+8.20^2}[/tex]

Marty will have to pay $18,000 for his $15,000 car.

While taking out a loan, the amount taken has to be repaid along with an interest. Thus, the amount paid back by the borrower is always greater than the initial amount that the borrower gets from the lender as a loan.

Here, we are given that Marty has to pay $500 per month for 3 years to repay the loan for his $15,000 car.

Thus, for one month he pays = $500
