a family wishes to determine the distance from their home to the nearest park. on a coordinate grid, the house sits at (0,0), and the park at (16,11)

using 1 unit = 10 yards, which vector represents the path from the house to the park, and what is the actual distance between them?

Help Plss C:a Family Wishes To Determine The Distance From Their Home To The Nearest Park. On A Coordinate

Answers

Answer 1

Answer:

components: {16,11}, distance: 194.16 yards

Step-by-step explanation:

to find the length of a point to another point that has different y and x points you use the pythagorean theorem (a^2 + b^2 = c^2)

16 and 11 are the distances from her house

16^2 + 11^2 = c^2

c^2 = 377

c = 19.416...

but we dont stop here

we have to convert this to yards by multiplying it by ten

19.416 * 10 = 194.16 yards

the answer of ur question is 0.25

1/4

Explanation:

4 as a fraction would be 4/1. Any whole number that you want to represent as a fraction goes over 1. When finding the reciprocal, we flip the numerator (number on top of the fraction bar) and the denominator (number on the bottom of the fraction bar.) Therfore, it would be 1/4. Hope this helps :)

What is slope ? Help me please

Answers

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

First, let's pick two points on the line.

    I am going to pick (10, 10) and (40, 20) as they are easier to read.

Slope is rise over run, or in other words, change in y over change in x.

    Let's do the math:

[tex]\frac{change.in.y}{change.in.x} =\frac{20-10}{40-10} =\frac{10}{30} =\frac{1}{3}[/tex]

    So, the slope is [tex]\frac{1}{3}[/tex] which we can also check by looking at the graph, find a point then move up and over three!

Have a nice day!

What was the cost of each teacup?

Answers

Using a linear equation, we find c using:

[tex]42 = 18 + 4c[/tex]

A linear function has the following format:

[tex]A(n) = A(0) + cn[/tex]

In which:

c is the slope, which is the price per unit.A(0) is the y-intercept, which is the fixed price.

In this problem, fixed price of $18, hence [tex]A(0) = 18[/tex]

She bough 4 units, and it cost $42, hence: [tex]n = 4, A(n) = 42[/tex]

Then

[tex]A(n) = A(0) + cn[/tex]

[tex]42 = 18 + 4c[/tex]

Hence, the equation to find c is:

[tex]42 = 18 + 4c[/tex]

What is the equation of the line that passes through the point (8,-8) and has a slope of -2​

Answers

Answer:

y=-2x+8

Step-by-step explanation:

Hi there!

We want to find the equation of the line that passes through the point (8, -8) and has a slope of -2

We can write this equation in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

Since we already know the slope of the line, we can immediately plug it into the equation as m:

y=-2x+b

Now we need to find b

As the equation of the line passes through the point (8, -8), we can use it to help solve for b, since (8, -8) is a solution to the equation, meaning that it will yield a true statement when plugged into the equation

So substitute 8 as x and -8 as y:

-8=-2(8)+b

Multiply

-8=-16+b

Add 16 to both sides

8=b

Now substitute 8 as b into the equation:

y=-2x+8

Hope this helps!

Point=(8,-8)m=-2

.Equation of line in point slope form

[tex]\\ \sf\longmapsto y-y_1=m(x-x_1)[/tex]

[tex]\\ \sf\longmapsto y+8=-2(x-8)[/tex]

A baker baked some loaves of bread. 240 loaves were sold by the end of the day. The baker was left with 9/25 of the number of loaves that were baked. How many loaves of bread did the baker bake on that day?

Please do this in a easy way and explain no algebra

Answers

Answer:

The baker baked 375 loaves of bread that day.

Step-by-step explanation:

The baker baked a total of x loaves of bread.

240 loaves were sold by the end of the day.

The baker was then left with 9/25 of the number of loaves that were baked.

We get the equation:

x-240 = 9x/25

When you solve the equation, you will see that x=375.

Therefore, the baker baked 375 loaves of bread that day.

add ( half the coefficient of the x- term)² to both sides

x² + 2(3)x + 9 = - 17 + 9

(x + 3)² = - 8 ( take square root of both sides )

The mapping of the strip pattern onto itself is a Glide reflection.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Glide reflection is a combination of reflection over a line and then translation along that line.

Each boundary line equation is of the form ...

  y = mx + b

the value of m is the coefficient of x. The value of b is the constant. You find their values by matching the given relation to the form above, and identifying the matching parts.

  y ≤ 1/2x +2   ⇒   m = 1/2, b = 2

  y < -2x -3   ⇒   m = -2, b = -3

_____

The slope (m) in each case tells you how many units up (m>0) or down (m<0) the line will go for each unit to the right. The y-intercept (b) in each case gives you a starting point on the y-axis, making it easier to draw the line.

The < part of each inequality symbol tells you the graph will be shaded below the boundary line. (Y-values in the solution set are less than those on the line.) The "or equal to" part of the first inequality symbol tells you the boundary line will be solid. (Y-values on that line are part of the solution set.) The lack of that in the second inequality tells you the boundary line will be dashed.
