Answer:
5,868,000
Step-by-step explanation:
2,934,000 x 2 = 5,868,000
Answer:
i think it would be 75.40
Step-by-step explanation:
The 6 would bring the 3 up one.
When you do a 90 degree rotation, you turn it a 1/4 - 1 quarter - , clockwise,
There are 360 degrees altogether so a 1/4 of it is 90 degrees. don't forget to turn it clockwise ( the way the clock goes )
Solve using limits, 0 to 2 and 2 to 10.
ex: M = From 0 to 2 (x^3)dx + From 2 to 10 (10-x)dx
and so on...
That was the biggest problem for me is figuring out the limits, but if you need more help here is an example solution

Answer: A) 45 square cm</h3>
============================================================
Explanation:
The length of 17 cm and slanted length of 10 cm are not used at all. They are likely thrown in as a distraction.
Instead, we focus on the horizontal base of 10 cm and the vertical height of 9 cm. The base and height are always perpendicular to one another.
The area of the triangle is therefore...
area = base*height/2
area = 10*9/2
area = 90/2
area = 45 square cm
It doesn't matter that this triangle is obtuse, the same area formula applies to any triangle.
------------
A longer method would have you compute the area of the dashed triangle, and the area of the two combined triangles (the largest overall triangle). Subtracting the two would lead to the answer of 45 cm^2. You'll need the pythagorean theorem to find the base of the dashed triangle, which then helps find the base of the largest triangle overall as well. At this point is when the 17 and 10 come into play, but I find the first method is much easier.
