Answer: 3.99797217..
Step-by-step explanation:
formula for the circumference is pi x diameter
divide circumference by pi
25.12/pi = 7.9959443...
divide that by two to get the radius which would be 3.997972...
Step-by-step explanation:
27^x / sqrt(9^y) = 3 and log2(x) - 2 = log2(y).
3^3x / 3^y = 3 and log2(x) - log2(4) = log2(y).
3x - y = 1 and x/4 = y.
Therefore x = 4/11 and y = 1/11.
11a = 18a + 21
11a - 18a = - 18a + 21
-7a = 21
7a = -21
a = -21/ 7
a = -3
Answer:
Range: {0,3,6}
Step-by-step explanation:
The range is the output, or in this case, the y values
Range: {0,3,6}
Answer:
60 degrees
Step-by-step explanation:
180-90=90
90-30=60
