Step-by-step explanation:
<h3>f(x) = x² + 2x - 2</h3><h3>f(-2) = (-2)² + 2 (-2) - 2</h3><h3> = 4 - 4 - 2</h3><h3> = - 2</h3><h3 />
Hope it will help :)
Probability of an event happening is given by:
probability of an event happening=number of ways it can happen/total number of outcomes
number of random selection=40
total number of patients who did not leave against medical advice=52,560
thus the probability that at random selection none of the 40 patients left the treatment center against medical advice will be:
40/52560
=0.00076
Answer:
The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.
Step-by-step explanation:
When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.
If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.
Answer:
and it's reciprocal is 
Step-by-step explanation:
4.5 is a number in between 4 and 5, as a fraction it is written as . To get the reciprocal you need to change it to an improper fraction so it becomes 
. The reciprocal will be 1 ÷ . This literally means the number will just invert and become
We know that
When we have
Here ,
a is the leading coefficient
c is the constant term
so, we can compare it with
so, we get
so,
leading coefficient is 5
constant term is 6......................Answer
