Step-by-step explanation:
Answer:
You need to sum at least 5000 terms
Step-by-step explanation:
Remember what the estimation theorem for alternating series says.
Given a series
An upper bound for the error of the series 
is 
so
For this case you want
is approximately 5000. So you must sum at least 5000 terms.
three shapes. three areas to find. three areas to add together to find the whole area. gotcha.
Step-by-step explanation:
- smaller rectangle
- larger rectangle
- right triangle
<h2>
smaller rectangle: </h2>
length is 7 cm and width is 4 cm, so the area is <u>28 square cm</u>
<h2>
</h2><h2>
larger rectangle:</h2>
width is 4 cm and length is 10 cm, so the area is <u>40 square cm</u>
Because the weird shape's bottom length was 13 cm. There are 3 cm and 7 cm on the top length(s) of the weird shape, next to each other. Looking at the dash lines, when adding 3 cm and 7 cm together, the larger rectangle's length is 10 cm.
<h2>right triangle: </h2>
base is 3 cm and height is 8 cm, so the area is (3x8)/2 = 24/2 = <u>12 square cm</u>
With knowledge from figuring out the larger rectangle's length being 10 cm and the weird shape's bottom length being 13 cm, we know the right triangle's base is 3 cm. (13 cm - 10 cm = 3 cm for the base of the right triangle).
Due to adding 4 cm and 4 cm of weird shape's width, which is also a right triangle's height.
<h2>weird shape's area from adding three shapes' areas: </h2>
28 + 40 + 12
= 80 square cm (ANSWER)
