Answer:
Step-by-step explanation:
178.54-35.65=142.89
then you do 142.89/12.99=11

Answer:
C. x = 3.71
Step-by-step explanation:
4 + 9(ln x) = 15.8
Subtract 4 from both sides.
9(ln x) = 11.8
Divide both sides by 9.
ln x = 11.8/9
x = e^(11.8/9)
x = 3.71
We can use substitution or elimination
Let’s use substitution
Make slope intercept equation for the first equation
Y = -x + 5
Now plug in the y value for the second equation
-5x - 4(-x + 5) = -18
-5x + 4x - 20 = -18
-1x = 2, x = -2
There is one solution
Answer:
Step-by-step explanation:
Probability of any incidence can only be a rational number.
Porbability can never be less than zero. It is basically defined as the ratio of
chance of occurence of an event to the total possible ways of occurence of the event. So an event cannot occur and the probability can be zero but never negative.
being a irrational number cannot be a possibkle vlue for probability.
Hence values which cannot be possible are .
The relative maximum of sin(x) is 1. This is because the period is 2pi and the graph reaches the maximum at odd multiples of pi/2 and sine of those values is 1 so the answer is c.
