If you'd graph this function, you'd see that it's positive on [-1.5,0], and that it's possible to inscribe 3 rectangles on the intervals [-1.5,-1), (-1,-0.5), (-0.5, 1].

The width of each rect. is 1/2.

The heights of the 3 inscribed rect. are {-2.25+6, -1+6, -.25+6} = {3.75,5,5.75}.

The areas of these 3 inscribed rect. are (1/2)*{3.75,5,5.75}, which come out to:

{1.875, 2.5, 2.875}

Add these three areas together; you sum will represent the approx. area under the given curve on the given interval:  1.875+2.5+2.875 = ?

Cindy is growing plants for a science project. During the project, one plant grows from a height of 7 cm to 10.85 cm. What is th
Leto [7]

Answer:

Percentage increase in the height is 55%.

Step-by-step explanation:

Since Cindy is growing plants for a science project. During the project Cindy found that one plant grows from 7 cm to 10.85 cm.

We have calculate percent increase in the height of the plant.

We know formula to calculate the percentage is

% Increase in the height = Net increase in the height×100/Initial length of the plant

                                         = \frac{(10.85-7)100}{7}= \frac{(3.85)(100)}{7}=\frac{385}{7}= 55%

Therefore % increase in the height of the plant is 55%.

10. During the hockey season, Elena
Debora [2.8K]

Answer:

Step-by-step explanation:

If I remember expanded form is putting all number in terms of being times 10 to a power.  starting with the ones place it's x10^0 which of course is just 1, so you don't need to include the x10 at all.

now, moving one either way  that 0 either  get 1 added to it or subtracted.  So in the 10s place it becomes x10^1 and the tenths place becomes x10^-1.  Similarly the hundreds place and hundreths place will have x10^2 and x10^-2 respectively.  So keep this pattern going to find each place of the number.  Can you list out what places are displayed in 5.625?

I will get you started, but let me know if you don't quite get it.  

5 + 6*10^-1 + ...

Can you figure out the rest?
