Well I’m not sure if I know how explain this mathematically but what I think happens is Josè is putting 150 dollars in and earning 3% interest quarterly instead of by the year, meaning his money is increasing more often then Janell, who only gets interest every year. I’m sorry if this isn’t what you were looking for

A small square of side 2x is cut from the corner of a rectangle with a width of 10 centimeters and length of 20 centimeters. Wri
love history [14]
Find the area of the rectangle. You can find the area of a rectangle with the following formula:

A = wl

w = width, and l = length.

Plug in your width and length:

20 * 10 = 200

The area of the rectangle is 200 square centimeters.

The area of a square is also given by width * length. Multiply the sides together:

2x * 2x = 4x^{2}

The area of a square is 4x^2.

Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:

200 - 4x^{2} cm^{2}

                                                      Question 1)

Given

The expression is 5xy

To determine

Find the value of 5xy if x = 2 and y = 3

5xy

substitute x = 2 and y = 3

5xy = 5(2)(3)

      = 5(6)

      = 30

Therefore, the value of 5xy = 30 if x = 2 and y = 3.

<em>Note: your remaining questions are not mentioned. But, the procedure may remain the same. Hopefully, your concept will be cleared anyway.</em>

Which graph best represents an exponential function?
stellarik [79]

Hey there! :)

Answer:

Choice B.

Step-by-step explanation:

We can eliminate each graph:

a). This is what is known as a step function. This is incorrect.

b). This is an exponential function because the graph is shaped like a geometric equation. This means that the rate of change is exponential. This is the correct choice.

c). This is an absolute value function. This is incorrect.

d). This is a graph of a polynomial. This does not represent an exponential function, which makes it incorrect.
