Answer:
<h2>The domain for this function is
where
.</h2>
Step-by-step explanation:
The given function is
Where 
represents cars. This function models the profits they make.
Now, as you can deduct already, we can define to different domains, the mathematical one and the reasonable one.
The reasonable domain is about all the useful values to the problem. For example, as we are talking about car, they can't wash -5 cars, so negative numbers are excluded. Similarly, they can't wash 6.75 cars, because that would imply an incomplete job.
Therefore, the domain for this function is where .
(Notice that we specify that the independent valur can only use whole positive numbers only).
I believe that’s false, because for every x there should only be one y, and x(5) has two y’s (1 and 3)
<h3>
Answer: Choice A) 0.20</h3>
===================================================
Explanation:
Let's say there are 1000 students. The students must take math, science or they can take both simultaneously.
- 65% of them are in math. So there are 0.65*1000 = 650 math students.
- 43% are in science, leading to 0.43*1000 = 430 science students.
- 13% are in both so we have 0.13*1000 = 130 students who are in both.
Now onto the sentence that says "Suppose a high school student who is enrolled in a math class is selected at random"
This means we only focus on the 650 math students and ignore the 1000-650 = 350 students who aren't in math.
Of those 650 math students, 130 are also in science (since 130 are in both classes).
The probability we're after is therefore 130/650 = 0.20
Answer:
83 degrees
Step-by-step explanation:
Add together the magnitudes of the outdoor and indoor temperatures:
|-15 degrees| + |68 degrees| = 83 degree temperature difference (Answer C).
The equation is y = 250(0.89)^x and the decay rate is 11%.
<h3>How to calculate the values?</h3>
The initial value will be:
= 250(0.89)^x
= 250(0.89^0)
= 250
The decay rate will be:
= 1 - 0.89
= 0.11
= 11%
In conclusion, the equation is y = 250(0.89)^x and the decay rate is 11%.
