Answer:
C. x ≈ 0.28
Step-by-step explanation:
A graphing calculator solution is attached. It shows ...
x ≈ 0.28
__
You can divide both sides of the given equation by 5, then take natural logs and divide by 5 again.
5e^(5x) = 20 . . . . . . given
e^(5x) = 4 . . . . . . . . divide by 5
5x = ln(4) . . . . . . . . take natural logs
x = ln(4)/5 . . . . . . . divide by 5
x ≈ 0.277259 ≈ 0.28
Answer:
Option (C) Miguel's daily wage=$70
Step-by-step explanation:
This can be expressed as;
Total amount a week=Amount he earns per day×number of days he works in a week
where;
Total amount a week=$490
Amount her earns per day=x
Number of days in a week=7 days, since wages are paid weekly even on days that Miguel does not go to work, like weekends.
replacing;
490=x×7
x=490/7
x=70
Miguel's daily wage=$70

Answer:
5 in
Step-by-step explanation:
12 3/4 x 2= 25 1/2
35 1/2- 25 1/2= 10
10/2=5
The line y = -2 is a horizontal line through -2 on the y axis.
Anything perpendicular to this horizontal line will be a vertical line. All vertical lines are of the form x = k where k is some fixed value.
In this case, the answer is x = 4 because want the vertical line to go through (4,-2). In other words, we want all points on the vertical line to have x coordinate of 4.
Side Note: the slope of y = -2 is 0 while the slope of x = 4 is undefined.
