What is the completely factored form of 2x2 – 32?
Answer:
[tex]2(x+4)(x-4)[/tex]
Step-by-step explanation:
The given expression is [tex]2x^2-32[/tex]
The GCF of the expression is 2. Hence, we can factor out 2
[tex]2(x^2-16)[/tex]
Now, we can write 16 as a perfect square
[tex]2(x^2-4^2)[/tex]
Apply the difference of squares formula [tex]a^2-b^2=(a+b)(a-b)[/tex]
[tex]2(x+4)(x-4)[/tex]

Option b is correct
Lucas is applying to both Stanford and Cal-poly. The probability that he gets accepted to Stanford is 0.4. The probability that he gets accepted to Cal-Poly is 0.3. The probability that he is accepted to both schools is 0.15.
a) What is the probability that he is accepted to one of the two schools?
b) What is the probability that he does not get accepted at either school?
The probability that Lucas is accepted to at least one of the two schools is 55%, while the probability that he does not get into either school is 45%.
Explanation:The subject of the question is probability theory, which is a branch of mathematics. Lucas has a 0.4 chance of getting into Stanford, a 0.3 chance of getting into Cal-Poly, and a 0.15 chance of getting into both. These are independent probabilities because they do not affect each other.
a) To calculate the probability that he gets accepted to at least one of the schools, we add the probabilities of him getting into each school, and then subtract the probability of him getting into both (because we're double counting that scenario). So, that's 0.3 (for Cal-Poly) + 0.4 (for Stanford) - 0.15 (for both) = 0.55, or 55%.
b) In probability theory, the total probability of all possibilities is always 1. So, to find the probability that he doesn't get into EITHER school, we subtract the probability that he gets into at least one school from 1. So, 1 - 0.55 (the answer from part a) = 0.45, or 45%. So, there's a 45% chance that Lucas doesn't get accepted into either school.

Suzanne is going to rent a car while she is out of town. One car rental company offers a flat rate of $35 per day plus $0.10 per mile. Another car rental company offers the same car for $25 per day plus $0.25 per mile. She will need the car for 5 days. How many miles would she need to drive for the first rental company to be a better deal?
Answer:
She need to drive more than 2000 miles for the first rental company to be a better deal .
Step-by-step explanation:
Case 1) One car rental company offers a flat rate of $35 per day plus $0.10 per mile
Let m be the no. of miles
She will need the car for 5 days.
So, total cost = [tex]35 \times 5 +0.10m=175+0.10m[/tex]
Case 2) Another car rental company offers the same car for $25 per day plus $0.25 per mile.
Let m be the no. of miles
She will need the car for 5 days.
So, total cost = [tex]25 \times 5 +0.25m=125 +0.25m[/tex]
Now we are supposed to find How many miles would she need to drive for the first rental company to be a better deal?
So, [tex]175+0.10m <125 +0.25m [/tex]
[tex]175+125 <125 +0.25m-0.10m [/tex]
[tex]300 < 0.15m [/tex]
[tex]\frac{300}{0.15} < m [/tex]
[tex]2000 < m [/tex]
So, she need to drive more than 2000 miles for the first rental company to be a better deal

Ralph likes 25 but not 24; he likes 400 but not 300; he likes 144 but not 145. which does he like:
Ralph would choose any number that is a perfect square.
The pattern Ralph likes is that he prefers numbers that are perfect squares. A perfect square is an integer that is the square of an integer. For example, he likes 25 because it is 52, 400 because it is 202, and 144 because it is 122. Numbers like 24, 300, and 145 are not perfect squares and therefore are not liked by Ralph.
To determine which number Ralph would like from a given list, you should identify which numbers are perfect squares. For instance, between the numbers 146 and 144, Ralph would like 144 as it is a perfect square (122) whereas 146 is not a perfect square.

The real answer is C. $71,829. Just took the engenuity test.
Mike's total taxable income is $71,829.
Explanation:To calculate Mike's total taxable income, we need to subtract his deductions and exemptions from his adjusted gross income. According to the given information, his adjusted gross income is $85,643. He claims two exemptions, which are each worth $3,650, so the total exemption amount is $7,300. He can deduct $896 for state income tax, $2,145 for charitable donations, and $3,473 for medical expenses. Thus, the total deduction amount is $6,514. Therefore, Mike's total taxable income is:
Total taxable income = adjusted gross income - (deductions + exemptions)
Total taxable income = $85,643 - ($6,514 + $7,300)
Total taxable income = $85,643 - $13,814
Total taxable income = $71,829
So, the correct answer is c. $71,829

A linear model projects that the number of bachelor's degrees awarded in the United State will increase by 19,500 each year. In 2001, 1.28 million bachelor's degrees were awarded. Use the inverse function to predict the number of years after 2001 that 1.7 million bachelor's degrees will be awarded.
The linear model predicts that approximately 22 years after 2001 (around the year 2023), 1.7 million bachelor's degrees will be awarded annually in the U.S.
Explanation:The problem is related to the mathematical concept of linear modeling. This model is represented by the function f(x) = 19500x + 1.28 million, where x is the number of years after 2001 and f(x) is the number of bachelor's degrees awarded in that year. The objective is to calculate 'x' when f(x) is 1.7 million. To do this, we use the inverse function.
The inverse function of f(x) = 19500x + 1.28 million is the function x = (f(x) - 1.28 million) / 19500. Substituting the known value f(x) = 1.7 million into the equation, we get: x = (1.7 million - 1.28 million) / 19500 ≈ 21.54. Since we cannot have a fraction of a year, we round this up to the next whole number.
Therefore, according to the linear model, it will be approximately 22 years after 2001, i.e., in the year 2023, when the number of bachelor's degrees awarded is expected to reach 1.7 million.

Using the linear model, it is predicted that 1.7 million bachelor's degrees will be awarded approximately 22 years after 2001, which corresponds to the year 2023.
Explanation:To predict the number of years after 2001 that 1.7 million bachelor's degrees will be awarded using a linear model, we start with the initial number of degrees awarded in 2001, which is 1.28 million. According to the model, the number of bachelor's degrees increases by 19,500 each year. We set up the equation: 1.28 million + 19,500x = 1.7 million. Here, x represents the number of years after 2001.
Solving for x gives us:
1.7 million - 1.28 million = 19,500x
420,000 = 19,500x
x = 420,000 / 19,500
x ≈ 21.54
Thus, it will take approximately 22 years after 2001 for 1.7 million bachelor's degrees to be awarded, which means this is expected to occur in the year 2023 (since 2001 + 22 = 2023).

If after turning off a applications the download speed increase to 0.15gb min will you be able to download the entire game now
Final answer:
To determine if you can download an entire game with a download speed of 0.15GB per minute, divide the total game size by the download speed. For a 1.5GB game, it would take 10 minutes to download at this speed.
Explanation:
Calculating whether you can download an entire game based on the download speed and the game's size is a problem that falls under the subject of Mathematics. To determine if the game can be fully downloaded, you would need to know the total size of the game. For instance, if the game is 1.5GB and your download speed is 0.15GB per minute, you can calculate the time it would take to download the game by dividing the total size by the download speed. In this example:
Total game size: 1.5GB
Download speed: 0.15GB/min
Time to download = Total size / Download speed = 1.5GB / 0.15GB/min = 10 minutes
Therefore, with a download speed of 0.15GB per minute, you would be able to download a 1.5GB game in 10 minutes. If you have enough time before you need to use the game, you will be able to download the entire game now.
