Hi, I need help I don't understand

Mathematics
1 answer:
Svetllana [295]2 years ago

Answer: 60cm^2

Step-by-step explanation:

Looking at the figure, you can see that the length is 5cm + 3cm = 8cm and the width is 2cm + 5cm + 2cm = 9cm.

The formula for area is length x width, therefore you do 8x9 which is 72.

Next, we solve for the two "dips" in the rectangle. We can do that by subtracting the area of the "mini-rectangles" from the whole figure:

72-2(2x3) = 60

Thus, 60cm^2 is your answer.

Find the value of the trigonometric ratio, cos L.
Alekssandra [29.7K]

Answer:

b/h

Step-by-step explanation:

remember SOH CAH TOA. Sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite/adjacent. So in this case use CAH for cos L. Adjacent to L is b, and the hypotenuse is h. Therefore the answer is b/h.

Write an explicit formula for an arithmetic sequence whose common difference is -4.5
makvit [3.9K]
If the difference is always -4.5, then it is always -4.5 times something, so that it changes -4.5 ever 1 number.  This means that our equation is y=-4.5x.  From there, we can add any constant, as it will not change the difference.  I will leave that up to you to pick, so the equation is y=-4.5x+C, where C is any real number.

Hope this helps!
