Answer:
$18
Step-by-step explanation:
Answer:
Step-by-step explanation:
- Initial amount = 2112 g
- Time = 188 days
- Half-life = 47 days
188 days / 47 days = 4 periods
<u>Mercury left after 188 days:</u>
- 2112 * (1/2)^4 =
- 2112* 1/16 =
- 2112/16 =
- 132 g
Answer:
Step-by-step explanation:
The line is parallel to the x axis, so its slope is 0
m = 0
the y intercept is -2.5
the line doesn’t intercept the x axis because is parallel to it
Answer:
1: n > -75
2: n < -12
Step-by-step explanation:
1: n/-3 - 8 < 17
n/-3 (- 8 + 8) < 17 + 8
n/-3 < 25
n/-3(-3) < 25(-3)
n < -75
n > -75 (switch symbol when you divide or multiply by a negative number)
2: n/-2 + 11 > 17
n/-2 (+ 11 - 11) > 17 - 11
n/-2 > 6
n/-2(-2) > 6(-2)
n > -12
n < -12 (switch symbol when you divide or multiply by a negative number)
Answer:
Step-by-step explanation:
A linear function is a polynomial function of the first degree that has the form:
f (x) = m*x + b or y=m*x + b
where y is the dependent variable, x is the independent variable, m is the slope of the line and b is the intercept with the Y axis.
The slope m measures the inclination of the line with respect to the abscissa axis, that is, the x axis. According to the value of the slope m, the linear function can be increasing if m> 0, decreasing if m <0 or constant if m = 0.
You know that the number of sea turtle deaths per year is modeled by f(x) = 13.42x + 109.118. Then the value of the slope is 13.42. In this scenario, the slope indicates that the number of deaths of sea turtles grows in a proportion of 13.42 with respect to the pollution index of the bay.
