To find:

The value of the given expression closest to the whole number.

Solution:

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the line models the height of a glider [y] in feet over [x] hours

The y - intercept i.e. the point where the graph cuts the [y] axis. From the graph we can see that point is (0, 3500).

Therefore, the y - intercept of the line is at (0, 3500).

#6) Yes; B, C, and D have lengths greater than one meter. and their areas are exactly one square meter

Step-by-step explanation:

Options B, C and D have an area of 1 square meter and their length is greater than 1 meter and the width is less than 1 meter.

Given that, Danah is planting a second strawberry patch and wants it to have an area of exactly 1 square meter.

How to find the area of a second strawberry patch?

To find the area of each different shape strawberry patch, you have to find out which options have an area of 1 square meter.

Area of rectangle formula=Length×Breadth.

From option A:

Area= 1/2 × 3/2=3/4 =0.75 square meters

From option B:

Area= 2/3 × 3/2 =1 square meters

From option C:

Area= 4/5 × 5/4 =1 square meters

From option D:

Area= 2/3 × 6/4=2/2 =1 square meters

Therefore, options B, C and D have an area of 1 square meter and their length is greater than 1 meter and the width is less than 1 meter.
