As modeled by the function below: t=0.007x^2+0.003x. The time it will take the computer to sort 15 objects is 1.62sec
What is Time?
Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.
Given:
t = 0.007x^2+0.003x
x = 15
Substituting the value in the equation we get,
t = 0.007(15)^2+0.003(15)
t = 0.007(225) + 0.045
t = 1.575 + 0.045
t = 1.62sec
Hence, It will take 1.65sec to sort 15 objects

If y =18 and x=60 what is the constant of proportionality
Final answer:
The constant of proportionality when y = 18 and x = 60 is calculated by dividing y by x, which results in a constant of 0.3.
Explanation:
To find the constant of proportionality when y = 18 and x = 60, we must assume that the relationship between y and x is directly proportional. This means that as x increases, y increases at a constant rate, and vice versa. If the relationship is directly proportional, we can write y = kx, where k is the constant of proportionality.
To calculate k, we simply divide y by x. So we have:
k = y / x
k = 18 / 60
k = 0.3
Therefore, the constant of proportionality is 0.3.
Choose the constant term that completes the perfect square trinomial x 2 - 18x
The correct answer should be +18

A different species of cockroach has weights that follow a normal distribution with a mean of 50 grams. after measuring the weights of many of these cockroaches, a lab assistant reports that 14% of the cockroaches weigh more than 55 grams. based on this report,what is the approximate standard deviation of the weights for this species of cockroaches?
To find the standard deviation of the weights of a species of cockroach when it is known that 14% weigh more than 55 grams, you can use the Empirical Rule of a normal distribution and solve using the given mean and the equivalent standard deviation for the 14% threshold. The estimated standard deviation in this case is around 4.63 grams.
Explanation:Your question is about using statistical information about a normally distributed population - in this case, the weights of a certain species of cockroach - to estimate the standard deviation of that population.
One thing we know about normally distributed data is that approximately 68% of all measurements fall within one standard deviation (either above or below) of the mean, about 95% fall within two standard deviations, and about 99.7% fall within three standard deviations. This is often referred to as the Empirical Rule or 68-95-99.7 rule.
According to the information provided, 14% of the cockroaches in the studied population weigh more than 55 grams. On a standard normal distribution, 14% represents approximately 1.08 standard deviations above the mean (you can find this value on a standard normal distribution table). Since we know that the mean weight is 50 grams, we can set up the following equation to solve for the standard deviation:
50 (mean weight) + 1.08 (standard deviation equivalents for 14%) * σ (standard deviation) = 55
Solving for σ we find that the standard deviation σ for the population of these cockroaches is approximately 4.63 grams.

Which fraction is equivalent to 4 over negative 9?
A.) -4 over 9
B) 4 over 9
C) -4 over -9
D) 9 over 4
Answer:
A) -4 over 9
Step-by-step explanation:
We have the fraction [tex]\frac{4}{-9}[/tex] the equivalent of this fraction is [tex]\frac{-4}{9}[/tex]
[tex]\frac{4}{-9}= \frac{-4}{9} =-\frac{4}{9}[/tex]
Both fractions are the same and equivalent, the negative sign makes the whole fraction negative regardless of whether it is in the numerator or denominator.

A machine laying underground cable can place 125 meters of cable in 5 minutes
The machine lays cable at a rate of 25 meters per minute. This is calculated by dividing 125 meters by 5 minutes.
To determine how quickly the machine can lay underground cable, we need to calculate the rate of cable it places per minute. We start by noting that the machine can lay 125 meters of cable in 5 minutes.
We calculate the rate as follows:
Divide the total length of cable by the total time: 125 meters / 5 minutes = 25 meters per minute.This means the machine lays cable at a rate of 25 meters per minute.
Complete Question: A machine laying underground cable can place 125 meters of cable in 5 minutes. What is the rate per minute?

Graph the line for y+1=−35(x−4) on the coordinate plane.
Just write what the coordinates would be
Answer:
(0, 139) and (139/35, 0)
Step-by-step explanation:
To graph a line, two points are needed. Taking x = 0 and replacing this value in the equation, we get:
y+1=−35(0−4)
y = 140 - 1
y = 139
Then, the point (0, 139) is on the line.
Taking y = 0 and replacing this value in the equation, we get:
0+1=−35(x−4)
1/(-35) = x -4
1/(-35) + 4 = x
139/35 = x
3.971 = x
Then, the point (139/35, 0) is on the line.

Scott bought three bags of candy with 75 pieces in each one. He plans to divide all the candy evenly among seven friends. How many pieces of candy will Scott have left for himself?
Answer:
The answer is only one piece of candy
Step-by-step explanation:
Firstly, we have to determine the total amount of pieces of candy:
There are three bags with 75 pieces in each one, so the total is:
[tex]75+75+75=225[/tex]
Then, in order to determine the amount of pieces of candy for every friend,
we have to divide the total amount by 7, where the remainder of the division is the answer.
[tex]\frac{225}{7}=32*7+1[/tex]
Remainder=1
Finally, every friend of Scott receive 32 pieces of candy evenly and Scott is left with only one piece of candy.

A pair of shoes is on sale for $29.95. What will the sales tax on the shoes be if the sales tax rate is
7 1/2%?
$1.99
$2.10
$2.25
$2.99
Option C)The sales tax will be $2.25.
Convert the sales tax rate from a percentage to a decimal,
7.5% becomes 0.075.
Multiply the decimal by the total cost of the shoes,
0.075 × 29.95
= 2.24625.
$2.25.
Therefore, the sales tax on the shoes will be $2.25,Option C

Find the solution of the differential equation 3e^(3x)dy/dx=â9x/y^2
To solve the given differential equation, variables need to be separated, followed by integration of both sides. Since the equation involves both exponential and inverse square terms, separation of variables and integration are key steps. A specific solution also requires substituting a given function of y into the found general solution to determine any integration constants.
Explanation:The question involves solving a differential equation 3e^(3x)dy/dx = -9x/y^2. First, we need to recognize this as a separable differential equation, which can be solved by isolating all terms involving y on one side and all terms involving x on the other side. After separation, we integrate both sides with respect to their respective variables.
Step 1: Separate the variables. We get dy/y^2 = -3x e^(-3x) dx.
Step 2: Integrate both sides. The integration of dy/y^2 with respect to y is -1/y, and the integration of -3x e^(-3x) with respect to x requires integration by parts or a table of integrals.
Step 3: Upon integration, we would find an implicit solution involving y and x, combined with an integration constant that needs to be determined based on initial conditions or additional information. Since specific initial conditions are not provided in the initial question, we'd include a constant C in our final expression.
For a specific solution when y(x) = cos(3x), additional steps are required to substitute this y expression into our general solution and solve for the constant.
