A computer can sort x objects in t seconds, as modeled by the function
below:
t=0.003.x² +0.001.x
How long, in seconds, will it take the computer to sort 12 objects?
Round your answer to the nearest hundredth of a second.
We are given that, a computer can sort x objects in t seconds, and the below relations is satisfied for each x and t
t = 0.003 x² + 0.001 xFor 12 objects, we can substitute x = 12
⇒ t = (3/1000) (12)² + (1/1000) 12
⇒ t = (12/1000) (3 × 12 + 1)
⇒ t = (12×37/1000)
⇒ t = 444/1000
⇒ t = 0.444
⇒ t ≈ 0.40 seconds (2 dp)
x+5= 3(x-4) + 5
What is the answer
Step-by-step explanation:
x + 5 = 3x -12 + 5
x + 5 = 3x - 7
Subtract 5 from both sides....
x + 5-5 = 3x -7 - 5
x = 3x - 12
Change the sign ...
12 = 3x - x
12 = 2x
12/2 = x
x = 6
hence 6 is the answer.......
[tex]\large\textsf{\textbf{Answer\::}}[/tex]
x=6
[tex]\large\textsf{\textbf{Calculations\::}}[/tex]
First , use the Distributive Property :
x+5=3(x-4)+5
x+5=3x-12+5
x+5=3x-7
subtract 3x on both sides :
x-3x+5=-7
-2x+5=-7
Subtract 5 on both sides :
-2x=-7-5
-2x=-12
divide by -2 on both sides :
x=6
We've found the value of x : x = 6 .

Show that the equation x^3 + x - 3 = 0 has a solution between 1 and 2
When x = 1:
1³ + 1 - 3 = -1
When x = 2:
2³ + 2 - 3 = 7
Since f(x) = x³ + x - 3 is continuous, it follows from the intermediate value theorem that for some c in the interval (1, 2), we have f(c) = 0, since f(1) < 0 < f(2).

A sample of restaurants in a city shows that the average cost of an appetizer is $6.32 with a standard deviation of $0.47. A brand new restaurant wants to get noticed by offering appetizers for a much lower price. To determine the lower price, should the formula use a z-value that is greater than or less than -1?
I couldn't figure out how to answer a specific question on the site, but the answer is "Less than -1" because they are looking for a price that is lower then the average, or mean price. It should be -1 standard deviation or lower.
Hope this helps someone
To determine the lower price, the formula should use a z-value that is less than -1.
How to utilize the z-value?We are given;
Mean; x' = $6.32
Standard deviation; s = $0.47
A positive z-score indicates the raw score is higher than the mean average while a negative z-score indicates the raw score is below the mean average.
Now, we want to find out the lower price from the definition above, we have to use a negative z-score which in this case will be -1.

Celine hosts a podcast about computers, and Paul hosts a podcast about parenting. Both podcasts have a set duration for each episode. Last year, Celine released 39 episodes and Paul released 42 episodes, for a total of 7,869 minutes of content. This year, Celine released 14 episodes and Paul released 41 episodes, which lasted a total of 6,117 minutes. How long is each episode?
Using a system of equations, it is found that each Celine episode is 65 minutes long and each Paul episode is 127 minutes long.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given by:
Variable x: Length of a Celine episode.Variable y: Length of a Paul episode.Last year, Celine released 39 episodes and Paul released 42 episodes, for a total of 7,869 minutes of content, hence:
39x + 42y = 7869
Then:
[tex]y = \frac{7869 - 39x}{42}[/tex]
This year, Celine released 14 episodes and Paul released 41 episodes, which lasted a total of 6,117 minutes, hence:
14x + 41y = 6117.
Since [tex]y = \frac{7869 - 39x}{42}[/tex]:
[tex]14x + 41\frac{7869 - 39x}{42} = 6117[/tex]
14x - 38.07x = -1564.64.
x = 1564.64/24.07
x = 65.
[tex]y = \frac{7869 - 39 \times 65}{42} = 127[/tex]
Hence, each Celine episode is 65 minutes long and each Paul episode is 127 minutes long.
