Answer:

555

Step-by-step explanation:

If each side of a square is 15 miles, we can find the total distance travelled by finding how many sides of squares were travelled.

You could either count the boxes, or, as I'm going to do, you could calculate the length of each straight line.

I switch between the y axis and the x axis, because we are travelling in different directions (if moving up/down we pay attention to y-axis, if moving right/left we pay attention to x-axis)

From 'Home' to the 'Restaurant', we are travelling from 6 to -7 on the grid. So, if we want to know the distance between them, we need to figure out how far apart they are. This is similar to figuring how far apart any two numbers are--we find the difference. (6) - (-7) [6 + 7] = 13. So, the amount of squares travelled from home to the restaurant is 13.

[I pay attention to the values along the x-axis for these two points because we are considering the distance along the x-axis]

[y-axis because it is vertical travel]

Restaurant (at -5) to campground (at 2) has a distance of : 7

[x-axis because it is horizontal travel]

Campground (at -7) to Rest Area (at -3) has a distance of : 4

[y-axis travel]

Rest Area (at 2) to the endpoint of that line segment (at 8) has a distance of: 6

[x-axis travel]

Endpoint of line segment (at -3) to endpoint below destination (at 3)  has a distance of : 6

[y-axis travel]

Endpoint below destination (at 8) to destination (at 9) has a distance of : 1

We can then add all of the distance travelled:

13 + 7 + 4 + 6 + 6 + 1

= 37

37 sides of boxes were travelled, so we can multiply:

37 x 15

= 555

because each box length is 15 miles.

So, the family travelled 555 miles

A group of students want to determine if a person's height is linearly related to the distance they are able to jump.

to determine the relationship between a person's height and the distance they are able to jump, the group of students measured the height, in inches, of each person in their class and then measured the distance, in feet, they were able to jump from a marked starting point.

Answers

The correlation coefficient between the student's height and the distance they were able to jump is 0.86.

What is the correlation coefficient?

The correlation coefficient is a number that ranges from -1 to 1. It shows the strength of the relationship between two variables. It also shows the direction of the relationship.

Positive correlation is when the two variables move in the same direction. If one variable increases, the other variable also increases. Negative correlation is when two variables move in different direction. If one variable increases, the other variable decreases. Zero correlation is when there is no relationship between the variables.

The correlation coefficient is calculated using a financial calculator.

Here is the complete question:

To find differences in the angles of the intersections we must know how many degrees each angle corresponds to. We must also take into account that the sum of the internal angles must equal 180°.

What is a triangle?

A triangle is a polygon that is characterized by having three sides, three vertices, and three angles. An indispensable rule of the interior angles of the triangles is that they must add up to 180º.

Triangles are classified according to their characteristics as shown below:

Equilateral triangle: It is a type of triangle that is characterized by having all equal sides. Consequently, all the angles of an equilateral triangle are 60º. The equilateral triangle is a regular polygon.Isosceles triangle: It is a type of triangle that is characterized by having two equal sides and one different. Consequently, it also has two equal angles.Scalene triangle: A scalene triangle is one that is characterized by having all its sides and angles unequal, that is, different from each other.

According to the above, depending on the measurements of the length of the sides and the angles of a triangle, its characteristics and classification change.

[tex]f(x) = {x}^{2} + 4x[/tex]

[tex]y = {x}^{2} + 4x[/tex]

For the x intercept, let y = 0

Trees after 5 years

Trees after 6 years

161+0.1(161)177trees

Answer:

177

Step-by-step explanation:

This scenario can be modeled as an exponential function.

General form of an exponential function: [tex]y=ab^x[/tex]

where:

a is the initial value (y-intercept)b is the base (growth/decay factor) in decimal formx is the independent variabley is the dependent variable

If b > 1 then it is an increasing function

If 0 < b < 1 then it is a decreasing function

If the number of trees increase by 10% each year, then the number of trees each year will be 110% of the number of trees the previous year.  Therefore, the growth factor is 110%.

Given:

a = 100 treesb = 110% = 1.10 (in decimal form)x = time (in years)y = number of trees in the orchard

Substituting the given values into the function:

[tex]\implies y=100(1.10)^x[/tex]

(where x is time in years and y is the number of trees in the orchard)

To find how many trees are in the orchard in the 6th year, input x = 6 into the found equation:

[tex]\implies 100(1.10)^6=177.1561=177\: \sf (nearest\:whole\:number)[/tex]

Therefore, Martin had 177 trees in his orchard in the sixth year.

Answer:  36pi (choice b)

===========================================================

Explanation:

Let x = length of side BC

This is the height of the cylinder. Think of a can that is laying on its side. The radius of this can or cylinder is CD

If point B has x coordinate of 12, and BC is 12 units long, this must mean point C has x coordinate of 12-x. This is plugged into the function to show that CD has a length of exactly [tex]\sqrt{12-x}[/tex]

This is the radius of the cylinder

The volume of a cylinder is [tex]V = \pi*r^2*h[/tex]

Plug in the radius and height mentioned to get this function in terms of x

[tex]V = \pi*\left(\sqrt{12-x} \ \right)^2*x[/tex]

That simplifies to

[tex]V = \pi(12-x)x[/tex]

or

[tex]V = \pi(12x-x^2)[/tex]

Ignore the pi portion for now.

We wish to maximize the function f(x) = 12x-x^2

Use either calculus (specifically derivatives) or a graphing calculator to find that the vertex is at (6, 36)

This means x = 6 leads to the largest f(x) value being 36.

Therefore, the volume V is maxed out when x = 6 and we get a max volume of 36pi cubic units.

Maximum height of a function

The maximum height of a function is the  point where the velocity the body is zero.


Given the function that represent the height of the swimmer as  h(t)=t^2−12t+27

If the velocity of the function is zero, hence;

h'(t) = 2t - 12

0 = 2t - 12

2t = 12

t = 6secs

Substitute t = 6 into the function as shown:

h(6) = 6^2−12(6)+27

h(6) = 36 - 72 + 27

h(6) = -36 + 27

h(6) = -9 feet
