Answer:

D. 1.4*10^-1 seconds

Step-by-step explanation:

We know that distance = rate * time

We know the rate = 3.00 • 10^8 meters per second

and the distance =4.2*10^7 meters


distance = rate * time

4.2*10^7 meters =  3.00 • 10^8 meters per second * time

Divide each side by  3.00*10^8

4.2*10^7 /3*10^8 =  3.00 • 10^8/3*10^8  * time

4.2*10^7 /3*10^8 =    * time

4.2/3  * 10^7/10^8 = time

When we divide exponents of the same base, we subtract the exponents keeping the base

1.4 * 10^(7-8) = time

1.4 * 10^-1 seconds = time

A. Plot the data for the functions f(x) and g(x) on a grid and connect the points.
labwork [276]

Answer:

  a) see the plots below

  b) f(x) is exponential; g(x) is linear (see below for explanation)

  c) the function values are never equal

Step-by-step explanation:

a) a graph of the two function values is attached

__

b) Adjacent values of f(x) have a common ratio of 3, so f(x) is exponential (with a base of 3). Adjacent values of g(x) have a common difference of 2, so g(x) is linear (with a slope of 2).

__

c) At x ≥ 1, the slope of f(x) is greater than the slope of g(x), and the value of f(x) is greater than the value of g(x), so the curves can never cross for x > 1. Similarly, for x ≤ 0, the slope of f(x) is less than the slope of g(x). Once again, f(0) is greater than g(0), so the curves can never cross.

In the region between x=0 and x=1, f(x) remains greater than g(x). The smallest difference is about 0.73, near x = 0.545, where the slopes of the two functions are equal.

Question 1
MAVERICK [17]
Question 1:
x - Tim`s age,  y - Coach Johnson`s age:
x + 10 = y
2 * ( x - 3 ) = y - 3
-----------------------
2 x - 6 = x + 10 - 3
2 x - x = 7 + 6
x = 13
Tim is 13 years old.
Question 2:
x - 62,500 = 0.25 * 125,000
x - 62,500 = 31,250
x = 31,250 + 62,500
x = 93,750

Karl and Mark are walking through the woods dropping breadcrumbs to help them find their way home. After ten minutes, their brea
musickatia [10]

In that three minute window (13 min - 10 min = 3 min), they used 24 bread crumbs (120 - 96 = 24).

So they're using 24 bread crumbs / 3 minutes or 8 crumbs/min.

The rate of change is a decrease of 8 crumbs/min from their basket.
