Length =l

Height = h

Area function = l * h = 924

Perimeter function = 2i + 2h = 122

Divide by 2

I + h = 61.

Plug in I or h for the other variable

I * (61 - I) = 924

61i - i^2 = 924

Factor the function

(-I + 28)(I - 33) = 0

l = 33 as l cannot be negative

61 - 33 = 28

h = 28

Difference between h and l is 33-28=5

Which relation is represented by the arrow diagram?
lorasvet [3.4K]

The relation represented by the arrow diagram is {(-3, 4), (-1, 5), (0, 7), (2, 2), (5, 7)}.

Option: C.

<u>Step-by-step explanation:</u>

A function is a relation in which each input value(domain) results in one output value(range). It is represented diagrammatically using the mapping method.

It shows how each element of domain and range are paired. That is like a flowchart it shows the input values marking its corresponding output value.

In the given diagram,

The values given in the left are domain and values given in the right are range.

Thus, -3 marks to 4, then can be written as (-3,4).

Similarly,

-1 marks 5 = (-1,5).

0 marks 7= (0,7).

2 marks 2= (2,2).

5 marks 7 =(5,7).

⇒ The complete points sequence is {(-3, 4), (-1, 5), (0, 7), (2, 2), (5, 7)}.

A biologist is comparing the growth of a population of flies per week to the number of flies a bullfrog will consume per week. S
Lubov Fominskaja [6]

Realize that since 2x and 3x - 1 are equal to each other, they are also equal to y. This means that we can craft two equations, y = 2x and y = 3x - 1.


When you want to solve a systems of equations via a graph, you need to plot both equations on a graph and determine the x- and y-value of where the lines intersect. In this case, we would plot both y = 2x and y = 3x - 1. These lines intersect at the point (1, 2).


Since we are trying to find the day the bullfrog will be able to eat the entire population, or x, we are going to use the x-value of our point as our answer. Thus, our answer is 1 day.

Use linear regression to find a
Inessa [10]

A function that fits the following points (0,5), (2,-13) is y = 9x + 5

<h3>Equation of a line</h3>

The equation of a line in slope-intercept form is expressed as;

y =mx +b

where;

m is the slope

b is the intercept

Given the following coordinates (0,5), (2,-13)

Slope = -13-5/2-0
Slope = -18/-2

Slope = 9

Since the y-intercept is b = 5, hence the equation of the line will be y = 9x + 5
