Y=-x^2+1 and y=x^2
When the two curves intersect their coordinates will be equal, so we can say y=y whenever a solution exists, so:
x^2=-x^2+1 add x^2 to both sides
2x^2=1 divide both sides by 2
x^2=1/2 take the square root of both sides
x=±√(1/2), so there are two solutions, we can use x^2 to find the corresponding y values.
y=x^2, y=1/2 in each instance, so the two point where the curves intersect are:
(-√(1/2), 1/2) and (√(1/2), 1/2) or if you want approximations....
(-0.7, 0.5) and (0.7, 0.5)

Answer:
Just multiply the number by the percentage.
Step-by-step explanation:
1. Make the percentage into a decimal (%50= 0.50)
2. Multiply the decimal by the number.
Step-by-step explanation:
It's simple here's The steps:
*Step 1
-Take your ruler and a pencil and construct a segment of any length on a piece of paper
-Then, you will try to set your compass opening to match the length of segment AB
-Take your compass. Make your sure that the pencil is included in it.
-Put the needle of the compass at endpoint A and adjust your compass so that the tip of your pencil touches endpoint B
*Step 2
-Put the needle of your compass at A and draw an arc
-Put the needle of your compass at B and draw an arc
-The two arcs should meet
*Step 3
-Draw the segments from the two endpoints to the point where the two arcs intersect
Answer:
She would have $33 left.
Step-by-step explanation:
First input the $2.50 into the "d" variable and multiply 6 by 2.50.
48−(6)(2.5)
Then, subtract 48 by 15.
48−15
Finally, you have your answer.
33
