Answer:
x=20
Step-by-step explanation:
This is a right triangle, so we can use the pythagorean theorem to help us find x.
The the theorem states that the sum of the legs squared is equal to the length of the hypotenuse squared.
Thus, our equation is:
x^2+48^2=52^2
Simplify.
x^2+2304=2704
Subtract 2304 from both sides.
x^2=400
Find the square root of both sides.
x=20

Answer:
1. Number 1 and 2 and 4 is a function, 2. number 1 is a function
Step-by-step explanation:
1)To know if it's a function or not run vertical lines through multiple places of the graph. If it is a function every single time you do the vertical line test it should only go over the line once. If you do the vertical line test on 3 you will see that it went over the line on the graph, so we know not a function. Graphs 1, 2, and 4m however, are different, when you do the vertical line test on those graphs it only goes over them once.
2) Choice (1) is a function because when drawing vertical lines through the graph it only goes over one.
Choice (2) is not a function because when drawing vertical lines through the graph it covers two points on the graph.
Choice (3) is not a function because when drawing vertical lines through the graph it goes over multiple points.
Choice (4) is not a function because when a vertical line is drawn, it goes over more than one point on the graph.
The vertical test is a way to determine if it is a function.
When looking at a table functions are one-to-one and many-to-one
Non-functions are one-to-many and many-to-many
Hoped this helped you : )
(-3, -2) is the vertex.
You can find this by plugging into -b/2a to find the x value and using the x value to find the y value.
And another spot on the vertex would be (0, 16), which is the y intercept.
Answer:
2
you times 3 and 4 and the divide by the 6
