It is an exponential function because it has a common ratio of 1:3

Solution:

1. We will plot the points on the coordinate plane, if they lie in a line it means they are linear.

2. Find the slope between each two points ,if you don't want to plot these points on coordinate plane,then by using the formula of slope between two points which is , =\frac{y_{2}-y_{1}}{x_{2}-x_{1}} ,if slopes are same between any two points it means these points are collinear.

As you can see in the coordinate plane that these points are not collinear.

Now , \frac{y}{x}=\frac{\text{First term}}{\text{Second term}}=\frac{162}{54}=\frac{54}{18}=\frac{18}{6}=\frac{6}{2}=3

It means this is a geometric progression because \frac{\text{Second term}}{\text{First Term}}=\frac{1}{3}

Option D : The data represent an exponential function because there is a common ratio of 1/3. is true statement.

Do lulus way. If you change the angles, you will not have a pentagon anymore. If you subtract, it wouldn’t be the same ratio:)

Need help with this problem for my cousin
yKpoI14uk [10]
You have separated the figure into three (3) parts. There are two squares (or rectangles on the bottom. Subtract 5 from 8 to find out the length of the side (right side). 8-5=3. Then subtract 3 from 8 (8-3=5). The new length is 5 ft. 5 multiplied by 5 is the area of one of the squares on the bottom (25 ft. squared). Multiply that by two to find the area of both the squares on the bottom (50 ft. squared).

There's also a rectangle on the top. The base is 15 ft. and the height is 3 ft. Remember that you subtracted 5 from 8 to find out the area of the two bottom squares. 15 multiplied by 3 is 45 (ft.)

Add 45 to 50 to get the area of the entire figure. (45+50=95 or 95 ft. squared).

95 ft. squared is the area of the entire figure. Hope this helped you.
