Answer: x=5.6
Step-by-step explanation:
Answer:
Two semi circles would equal one circle.
The perimeter of a circle is PI x diameter.
The diameter of the circle is shown as 56 m
The perimeter of the 2 ends = 56 x 3.14 = 175.84
The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.
Total perimeter = 260 + 175.84 = 435.84 m.
Step-by-step explanation:
Step-by-step explanation:
4^m * 4^2 = 12
4^(m + 2) = 4^(log4 12)
m + 2 = log4 (12)
m = log4 (12) - 2.
Answer:
decay
2% decrease
Step-by-step explanation:
The growth factor is the base of the exponent: 0.98. Its relation to the rate of change is ...
growth factor = 1 + rate of change
0.98 = 1 + (-0.02)
So, the rate of change is -0.02 = -2%. Since the rate of change is a 2% decrease, it represents decay.
Answer:
A: true
B: true
C: false
D: true
E: true
Step-by-step explanation:
A: always true, m is the slope, and b is the y-intercept (starting value)
B: always true, m is always constant within the equation
C: false, initial value can be 0, e.g. in the equation y=5x, the initial value is 0
D: always true, being a line is part of the definition of linear
E: true, if the equation is in the form x = [a number], it is a vertical line where the x value is always the given number
