Ответ:
La corredora correría 9 kilómetros y 24 pies.
Step-by-step explanation:
multiplique la longitud de una vuelta (1.54) por cuántos de ellos corrieron (6) para obtener cuántos kilómetros corrieron (9.24)
Ответ:
We are given the following data in tabulated form:
time (minute), x distance from surface (m), y
0 63
1 105
2 147
3 189
We can see that for every 1 minute increase in time, there is a constant 42 m increase in distance from the surface. Therefore the equation relating the two variables is linear in the form:
y = m x + b
where m is the slope and b is the y-intercept
Part A.
We can use the similar triangles to explain why the slope at points A and B is similar as the slope at points A and C by calculating for the slope in each case. The formula for slope m is:
m = (y2 – y1) / (x2 – x1)
Slope between A (2, 147) and B (1, 105):
mAB = (147 - 105) / (2 – 1) = 42
Slope between A (2, 147) and C (0, 63):
mAC = (147 - 63) / (2 – 0) = 42
Hence mAB = mAC
Part B.
The intial value is the value of y intercept (b). The value of b is the value of y when x = 0, hence:
initial value = b = 63
The slope of the graph is m = 42 and it tells us that there is 42 m change in distance per 1 minute of time.
