Choose the English sentence that expresses the contrapositive of this statement: "If the computer crashes, the software needs to be re-installed" If the computer crashes, the software does not need to
Answers
The contrapositive of the statement "If the computer crashes, the software needs to be re-installed" is "If the software does not need to be re-installed, the computer did not crash."
The contrapositive of a statement is formed by negating both the hypothesis and conclusion, and then reversing the order of the two statements. In this case, the hypothesis is "the computer crashes" and the conclusion is "the software needs to be re-installed."
To form the contrapositive, we negate both of these statements and reverse the order:
Negated hypothesis: The computer does not crash.
Negated conclusion: The software does not need to be re-installed.
Putting these two statements together, we get the contrapositive:
If the software does not need to be re-installed, the computer did not crash.
In other words, if the software is working properly, then the computer must not have crashed.

Step-by-step explanation:
the second option 1/(125n¹²)
why ?
when we have the exponent of an exponent, we can multiply the exponents.
so, 4×-3 = -12
a negative exponent means 1/... (with the corresponding positive exponent in the denominator).
and an exponent of the multiplication of factors means that the exponent is to be used for every factor in the multiplication.
so, the exponent -3 has to be applied to 5 and to n⁴.
this gives us 5^‐3 and n^-12 as factors.
the result is 1/(5³) × 1/(n¹²).
and that is the mentioned result above.

Answers
It is possible to add another data point that would be reasonable, even though no measurements were made. This data point could be an estimate or a prediction based on the existing data points. For example, if the existing data points show a linear relationship between acceleration and force, it would be reasonable to add a data point that falls along the same line.
One possible data point that could be added is (3m/s2, 4n). This data point falls between the existing data points (2m/s2, 3n) and (5m/s2, 5n), and would be a reasonable estimate based on the existing data.
Another possible data point that could be added is (7m/s2, 6n). This data point falls along the same line as the existing data points, and would be a reasonable prediction based on the existing data.
Overall, it is possible to add another data point that would be reasonable, even though no measurements were made, as long as the data point is based on the existing data and follows the same pattern or relationship.

A computer monitor has a width of 14.60 inches and a height of 10.95 inches. What is the area of the monitor display in square meters? area How many significant figures should there be in the answer? 2 3 4 5
Answers
The area of the computer monitor display is approximately 0.103 square meters, with three significant figures.
The area of the monitor display in square meters is found by converting the measurements from inches to meters and then calculate the area.
The conversion factor from inches to meters is 0.0254 meters per inch.
Width in meters = 14.60 inches * 0.0254 meters/inch
Height in meters = 10.95 inches * 0.0254 meters/inch
Area = Width in meters * Height in meters
We calculate the area:
Width in meters = 14.60 inches * 0.0254 meters/inch = 0.37084 meters
Height in meters = 10.95 inches * 0.0254 meters/inch = 0.27813 meters
Area = 0.37084 meters * 0.27813 meters = 0.1030881672 square meters
Now, we determine the number of significant figures.
The measurements provided have four significant figures (14.60 and 10.95). However, in the final answer, we should retain the least number of significant figures from the original measurements, which is three (10.95). Therefore, the answer should have three significant figures.
Thus, the area of the monitor display in square meters is approximately 0.103 square meters, with three significant figures.

Answers
Part A: The two factors are 4 and (8 - 3x).
Part B: The first factor has one term, and the second factor has two terms.
We have,
Part A:
The expression 4(8 - 3x) consists of two factors.
The first factor is coefficient 4, which multiplies the entire expression within the parentheses.
The second factor is (8 - 3x), which represents the expression inside the parentheses.
Part B:
To determine the number of terms in each factor, we need to identify the terms within the parentheses and the term created by the coefficient.
Within the parentheses, we have two terms: 8 and -3x.
The term 8 is a constant, while -3x is a variable term with a coefficient of -3 and the variable x.
Therefore, there are two terms within the second factor.
The coefficient 4 is considered a single term in itself because it is a constant value.
Thus, there is one term in the first factor.
Thus,
Part A: The two factors are 4 and (8 - 3x).
Part B: The first factor has one term, and the second factor has two terms.

Write your answer as a whole number, fraction, or mixed number. Simplify any fractions.
Answers
Answer:
3 times.
Step-by-step explanation:
She has 1 1/2 hour to spend in the gym.
1 hr = 60 minutes.
1/2 of an hour= 1/2 * 60= 30 minutes.
In total, she spends 90 minutes in the gym.
If 1/3 of an hour is meant in running, it translates into: 1/3 * 60 = 20 minutes.
If 1/6 of an hour is spent in weight-lifting, it translates into: 1/6 * 60 = 10 minutes.
In total, she spends, 20 minutes + 10 minutes = 30 minutes for both activities.
To obtain the number of times she would perform both activities, we divide the total amount of time spent in the gym by the amount of time spent for both activities.
90 minutes/30 minutes= 3 times for each cycle.

Answers
The amount of work needed to stretch the spring 18 in. from its natural position is 3.75 ft-lb.
According to the Hooke's Law, the work done on the spring is:
W = 1/2. k . x²
Where:
k = spring constant
x = displacement.
Notice that the work done is directly proportional to x².

W₁ : W₂ = x₁² : x₂²
Parameters given:
W₁ = 15 ft-lb
x₁ = 3 ft
x₂ = 18 in. = 1.5 ft
Plug the above parameters into the ratio equation:

Jack and charlie each deposit $17,250 into accounts that earn 6% interest for 6.5 years. Jacks account earns annual compound interest. Who will earn more interest after 6 years, and how much more interest will they earn?
Answers
From the amounts found using simple and compound interest formulas, we found that Carlie earns more interest than Jack by $1009.45.
What is the difference between simple and compound interests?
Simple interest is based on the principal amount, which is the main distinction between it and compound interest. Contrarily, compound interest is calculated using the principle sum and interest that has been compounded over the course of a period. Simple interest is a predetermined proportion of the principal amount borrowed or lent that is paid or received over a set period of time. Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.
The complete question is given below.
Given,
The principal amount deposited by both Jack and Carlie P = $17,250
The rate of interest r = 6% = 0.06
The time period = 6.5
Jack's account earns annual simple interest and Carlie's account earns annual compound interest.
So the amount in each person's account after a time period of t = 6 years.
Jack:
Amount = P(1+rt) = 17250 ( 1 + 0.06*6) = $23,460
Carlie:
number of times compounded in a year n = 1
Amount = \(P(1 + \frac{r}{n})^{nt}\) = 17250 ( 1+0.06)⁶ = $24,469.45
Therefore from the amounts found using simple and compound interest formulas, we found that Carlie earns more interest than Jack by $1009.45.

Paul hits a baseball straight up in the air. The baseball is hit with an initial velocity of 70 feet per second when it is 3. 5ft off the ground. Write the quadratic function models the height h of the ball after t seconds in flight
Answers
The quadratic function that models the height h of the ball after t seconds in flight is h(t) = -16t² + 70t + 3.5.
When a ball is thrown straight up in the air, its height above the ground can be modeled by a quadratic function. The standard form of a quadratic function is h(t) = at² + bt + c, where a, b, and c are constants. In this case, the ball is thrown with an initial velocity of 70 feet per second, which means that its initial height is 3.5 feet (the height of the person throwing the ball).
The acceleration due to gravity is -32 feet per second squared (assuming the positive direction is upward), so the coefficient of the t² term is -16 (½ of -32). The coefficient of the t term is 70, since the initial velocity is 70 feet per second. The constant term is 3.5, since that is the initial height of the ball.
Therefore, the quadratic function that models the height h of the ball after t seconds in flight is h(t) = -16t² + 70t + 3.5. This function can be used to find the height of the ball at any time t after it is thrown.
