circumference = 2xPIxr
length from center of the circle would be the radius = 25
circumference = 2 * 3.14 * 25 = 157
Answer is B. 157 m

Answer:
24.15
Step-by-step explanation:
0.05*20=1
total is 21 dollars,
0.15*21=3.15
21+3.15=24.15
Answer:
The value of k will be -4
Step-by-step explanation:
We have given polynomial
It is given that x+1 is factor of the polynomial
And we have to find the value of k
As x+1 is the factor of polynomial so x+1 = 0 that is x = -1 will be the root of polynomial
So if we put x = -1 in the polynomial then the p(-1) will be zero
So
So the value of k will be -4
Answer:
Linear function
y = 2x - 1
Step-by-step explanation:
This is a linear function because the line is straight, having no curved.
The equation for a linear graph is y=mx + b.
x and y represent points on he graph.
"m" represents the slope of the graph. Reading from left to right, if a positive slope, then the graph continues upward. If negative, then it's a graph down downwards.
"b" represents the y-intercept, when the graph hits the y-axis. It's also the initial value.
In the photo, we can see the y-intercept is (0, -1).
Slope is calculated by rise over run. Choose two random points on the graph. Count the "rise", or how many vertical units are between the points. If the point on the right is lower than the point on the left, the rise is negative. Count the "run", which is the number of horizontal units between the points.
For the point (0, -1) and (3, 5).
m = rise/run
m = 6/3
m = 2
Substitute m=2 and b= -1 into the equation of a line.
y = 2x - 1
