The population of a city increases by 4000 people each year. In 2025, the population is projected to be 450,000 people. What is an equation that gives the city’s population p (in thousands of people) x years after 2010?

Answers

Answer 1
p = 390,00 + 4000x

450,000 people - (15years x 4000) = 390k in 2010
 
15 years is the difference between 2010 and 2025
subtract 60k (that is the 15 years multiplied by 4k) from 450k and you get 390k.

Westley is 9 yars old. He is 3 years younger than his brother, Milo. Write and solve a subtraction equstion toshow how old Milo is.

Answers

x represents Milos age.

x - 3 = 9
add 3 to both sides to isolate x

x = 12

Milo is 12 years old.
Final answer:

To find Milo's age given Westley's age and the fact that Westley is 3 years younger than Milo, we can set up a subtraction equation and solve for Milo's age.

Explanation:

To find out how old Milo is, we can use the given information that Westley is 9 years old and 3 years younger than Milo. We can set up a subtraction equation by subtracting 3 from Westley's age.

Let's represent Milo's age as 'x'. The equation would be:

Westley's age - 3 = Milo's age

Substituting Westley's age of 9 into the equation:

9 - 3 = x

Simplifying the equation:

x = 6

Therefore, Milo is 6 years old.

What is the area of the triangle in the diagram?

Answers

check the picture below.

Answer:

Option A is the answer.

Step-by-step explanation:

The area of the triangle is given as :

[tex]A=\frac{1}{2}\times base\times height[/tex]

Base will be given by :

[tex]\sqrt{(x1-0)^{2}+(y1-0)^{2}}[/tex]

= [tex]\sqrt{x1^{2}+y1^{2}}[/tex]

Similarly the height will be given by:

[tex]\sqrt{(x2-0)^{2}+(y2-0)^{2}}[/tex]

= [tex]\sqrt{x2^{2}+y2^{2}}[/tex]

Now, putting these dimensions in the formula we get:

[tex]\frac{1}{2}\times \sqrt{(x1^{2}+y1^{2})(x2^{2}+y2^{2})}[/tex]

Therefore, option A is the answer.

A problem states: " there are 3 more baseballs than bats in a dugout. There are 15 bats and baseballs in the dugout in all. How many bats are in the dugout?" Let b represent the number of bats. Which expression represents the situation?

Answers

9 baseballs and 6 bats

Answer:

The required equation is 2b+3=15.

Number of bats = 6

Number of baseballs = 9

Step-by-step explanation:

Let b be the number of bats.

It is given that there are 3 more baseballs than bats in a dugout.

Number of baseballs = b + 3

Number of bats and baseballs in the dugout in all is

[tex]Total=b+(b+3)[/tex]

[tex]Total=(b+b)+3[/tex]

[tex]Total=2b+3[/tex]

There are 15 bats and baseballs in the dugout in all.

[tex]2b+3=15[/tex]

The required equation is 2b+3=15.

Subtract 3 from both sides.

[tex]2b=15-3[/tex]

[tex]2b=12[/tex]

Divide both sides by 2.

[tex]b=6[/tex]

The value of b is 6. So, the number of bats is 6 and number of baseballs is 6+3=9.

The ______________ between any two points on a number line is the absolute value of the difference of the coordinates.

Answers

The distance between any two points on a number line is the absolute value of the coordinates.

The distance between any two points on a number line is the absolute value of the difference of the coordinates.

What is number line?

Number lines are the horizontal straight lines in which the integers are placed in equal intervals. All the numbers in a sequence can be represented in a number line. This line extends indefinitely at both ends.

Since,the difference of the coordinates between any two points on a number line is the distance between the coordinates,

Let two points a and b on the number line, we define the distance between these two points as

|a−b|

where |…| is the absolute value function. As we can see, the distance between two points is always non-negative.

So, the absolute value of the difference of the coordinates between any two points on a number line is always positive.

Hence,The distance between any two points on a number line is the absolute value of the difference of the coordinates.

Need some help! Graph the equations y=3x-5 and x+3y=6 on the same xy-plane. What is significant about these two lines? (Explain your answer)
Thanks!

Answers

To solve this, we must first put both lines in Slope Intercept Form (y=mx+b where m is the slope and b is the y-intercept).

y=3x-5 is already in SIF, so we only need to work on the other one.

 x+3y=6
-x       -x
 3y=-x+6
 /3      /3
 y=-1/3x+2

Now we have both equations in slope intercept form, so we can start graphing from the y-intercepts and just follow the slopes.

When we do this, we will see that the lines meet at an exactly 90° angle. When a pair of lines does this, it means they are perpendicular.

Below I have attached an image that has both lines graphed so that you may visualize it. The green dots show the slopes, while the highlighted areas show the y-intercepts. Note that the lines intersect at a 90° angle, making them perpendicular.

If two variables were completely correlated, their correlation coefficient would be:

Answers

Pearson's correlation coefficient 'r' measures the degree to which two variables are correlated. The value is between -1 and 1. Negative values correspond to negative correlation (as one variable increases, the other variable decreases) whereas positive values correspond to positive correlation. The larger the absolute value of r, the closer a correlation graph resembles a set of points on the same line. Therefore, if two variables are completely correlated, the correlation value is 1 or -1, depending on whether the correlation is positive or negative.
