Answer:
A.
Step-by-step explanation:
π/4 radians = 45°
In a 45-45-90 degree angle, the ratio of the lengths of the sides is
1 : 1 : √2
x = y = 1/√2
x = y = √2/2
Answer: A.
Multiply the amount of water by the percentage:
100 x 0.035 = 3.5g of salt.
The equation is y = -1/2x - 2 so the slope is -1/2
The radius, i think, I'm not 100% sure what you're asking
Although we do not know the exact values of the zeros, we can find them by plugging our answers back into the equation. After process of elimination, we come to our answer which is C. Process of elimination is a test taking strategy which often helps in math, especially when quadratic formulas are present.
