Answer:
w to the power of two, or w squared
Step-by-step explanation:
Yes, one way you can express w^2 verbally, is by saying w to the power of two. However, you can also express this by saying w squared.
Step-by-step explanation:
A. 2(10)-(-10)
20 -(-10) -------> (-)×(-) =(+)
20 + 10
30
B.29 + 1
30
You need to change 17% to decimal by moving the decimal to the right by 2x
so you will get .17*800=136
Answer:
Step-by-step explanation:
Let's solve 2x^2 = -X^2 - 5x - 1. Consolidate all terms on the left side and write 0 on the right side:
3x^2 + 5x + 1 = 0. This is a quadratic equation. Let's solve it for x using the quadratic formula:
a = 3, b = 5, c = 1, and so the discriminant is b^2 - 4ac = 5^2 - 4(3)(1) = 13. Because the discriminant is positive, we know that there are two distinct, real roots; the graphs of y = 2x^2 and y = x^2 - 5x - 1 intersect in two places whose x-coordinates are the real roots mentioned above.
Answer A is not correct as stated, but would be correct if we were to replace "the y-coordinates" with "the x-coordinates."
Answer C would be correct if and only if we write y = x^2 - 5x - 1.
