Answer:
C) (square root 2)/2
Step-by-step explanation:
In quadrant III, the sine of an angle is positive. The value will be ...
sin(Θ) = √(1 -cos(x)^2) = √(1 -(-√2/2)^2) = √(2/4)
sin(Θ) = (√2)/2
Answer:
D: 6√30
Step-by-step explanation:
Simplify the following:
sqrt(20) sqrt(3) sqrt(18)
sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):
sqrt(20) sqrt(3)×3 sqrt(2)
sqrt(20) = sqrt(2^2×5) = 2 sqrt(5):
2 sqrt(5) sqrt(3)×3 sqrt(2)
2×3 = 6:
6 sqrt(5) sqrt(3) sqrt(2)
sqrt(5) sqrt(3) sqrt(2) = sqrt(5×3×2):
6 sqrt(5×3×2)
5×3 = 15:
6 sqrt(15×2)
15×2 = 30:
Answer: 6 sqrt(30)
Answer:
66%
Step-by-step explanation:
50 - 17 = 33, so that is the difference between the two numbers. Percent change is the change over the original, so 33/50. 33/50 equals 66/100, so the percent change is 66%
Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. y = logax
If the price of an object drastically dropped 75%, then the dropped price is equal to 25% of the original price. That means that to find the original price, we have to multiply by the reciprocal of 25% (4). The original price would be $85.99 * 4 which is $343.96.
