Answer:
Step-by-step explanation:
During the breaststroke competitions of a recent olympics, Nelson diebel swam 100 meters in 62 seconds, this means that his unit rate would be 100/62 = 1.61 meters per second.
Mike bower man swam 200 meters in 130 seconds. This means that his unit rate would be 200/130 = 1.54 meters per second. The rate of 1.61 meters per second is higher than the rate of 1.54 meters per second. Therefore, Nelson diebel swam at a faster rate.
There is no pictures to choose the right one among tem.
However the equation could be rewritten as follows:
y=√(x²-9)
It is a HORIZONTAL parabola with the following constraint: 3=<x=<-3
Answer:
Step-by-step explanation:
The equation of a line
y = mx + c
y - intercept point y
m - slope of the line
x - intercept point x.
c - intercept of the line
Step 1: find the slope
m = y2 - y1 / x2 - x1
Given two points
( -7 , -7) ( -7 , 4)
x1 = -7
y1 = -7
x2 = -7
y2 = 4
Insert the values into the equation
m = 4 - (-7) / -7 -(-7)
m = 4 + 7 / -7 + 7
m = 11/ 0
Step 2: sub any of the two points given into the equation
y= mx + c
y = 11/0x + c
(-7 ,4 )
x = -7
y = 4
4 = 11/0(-7) + c
4 = -77/0 +c
-77/0 is math error which means that the points are not correct
35.5 ft is the width of the room
<span> 80/-40=-40/20=-2,
the sequence: 80, -40, 20 is a geometric sequence
its general formula is Vn+1 = q Vn, where q= -2,
if we put </span>Vn+1 = f(x)
<span> Vn = x
so we have f(x)= -2x so the graph that represents the sequence is graph of linear equation
</span>
