To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43
Area of a square = l * w
Area of a circle = 3.14 * r^2
Area of semicircle = 3.14 * r^2 * 1/2
Area of shaded region: Area of square - Area of 2 semicircles
Area of square => 4 * 4 = 16
Area of both semicircles => (3.14 * r^2 * 1/2)*2 = 12.56
16 - 12.56 = 3.44
3.44 units^2 is the answer
I hope this helps!
Choice D) earns 5 times as many points compared to previous level
Let's say she's at level x = 1. That means she earns y = 5^x = 5^1 = 5 points.
At level x = 2, she earns y = 5^x = 5^2 = 25 points
When x = 3, we have y = 5^x = 5^3 = 125 points
And so on. Each new level earns her 5 times as many points as the previous level.
13. Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
14. Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia or related nitrogenous compounds in soil.
This is all i can give dude im still learning about this
Well first exponiantial growth, always increases. so
The first one goes
which we can see that doesn't apply
The second one goes
the third one goes
the fourth one goes
so the only options are the second one and the fourth one, but when the exponent is negative the function should decrease so the answer is B
She counted the squares instead of using the scale.
The scale, the numbers on the x amd y axis dont fo by ones, they go by sixes
1. 57 degrees
3. 117 degrees
The last 3
Pls mark a brainliest!
