Y = (2x^2)+3 is a function because when graphed, you have an even function traveling infinitely upwards. By doing the vertical line test (drawing a vertical line at any point on the function) you can see that the vertical line only intersects one point on the graph at a time, which means the equation is a function.
Answer: Yes, it is a function.
2/7 im pretty sure hope it helped
The midpoint is 15 hope i helped
Answer:2/pi
Step-by-step explanation:
First, name the points. Top Left will be A, Top Right will be B, Bottom Right will be C, and Bottom Left will be D. Now, the area of ABCD is 4. Then, we have to find the area of the circle. The center to the midpoint of AB is 1. The length of the midpoint of AB to B is 1. So, using the Pythagorean Theorem, it will be 1^2 + 1^2 = 2, then it will be sqrt2. Finding the area of the circle will be easy now that we have the radius. sqrt2*sqrt2*pi = 2pi. So, it will be 4/2pi, and simplified, it will be 2/pi.
The answer is 20. 4 x 1/5 = 4 x 5. 4 x 5 = 20
