Answer:
-8x^2+3x-6
Step-by-step explanation:
(-4x^2+ 3x + 3) - (4x^2 +9)
Distribute the minus sign
(-4x^2+ 3x + 3) - 4x^2 -9
Combine like terms
-8x^2+3x-6

03.05 Inequalitie
Think of an activity that you enjoy or are interested in. Some examples are reading, swimming, or leveling up your gaming character. Use your activity to work through the following problems:
Create a scenario that leads to an inequality of the form ax + b > c. You can use any of the inequality symbols (>, ≥, <, ≤) in your inequality. For this step, just write the word problem.
Write the inequality and show all work to solve the inequality.
Graph the solution to your inequality on a number line.
Explain what your solution means in the context of the problem.
Answer:
Kinetic energy = 135 kJ
Potential energy = 73.5 kJ
Explanation:
Mass of sky diver = 75 kg
Velocity = 60 m/s
Height = 100 m
Kinetic energy is given by the expression, 
, where m is the mass and v is the velocity.
So Kinetic energy = 
Potential energy is given by the expression, PE =mgh, m is the mass, g is the acceleration due to gravity value and h is the height.
So, Potential energy = 75*9.8*100 = 73500J = 73.5 kJ
Answer:
ans=13.59%
Step-by-step explanation:
The 68-95-99.7 rule states that, when X is an observation from a random bell-shaped (normally distributed) value with mean 
and standard deviation 
, we have these following probabilities
In our problem, we have that:
The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 53 months and a standard deviation of 11 months
So 
So:
-----------
-----
What is the approximate percentage of cars that remain in service between 64 and 75 months?
Between 64 and 75 minutes is between one and two standard deviations above the mean.
We have 
subtracted by is the percentage of cars that remain in service between one and two standard deviation, both above and below the mean.
To find just the percentage above the mean, we divide this value by 2
So:
The approximate percentage of cars that remain in service between 64 and 75 months is 13.59%.
the correct question is
Compute the total cost per year of the following pair of expenses. Then complete the sentence: On an annual basis, the first set of expenses is _% of the second set of expenses.Sheryl spends $17 every week on cigarettes and spends $24 a month on dry cleaning.
we know that
1 year is equal to 52 weeks
1 year is equal to 12 months
To calculate:
$17 * 52 = $884
$24 * 12 = $288
then
884/288 = 3.0694
* 100 = 306.94%

the answer is
<span>306.94%</span>
