Which shows a difference of squares?
10y^2−4x^2
16y^4−x^2
8x^2−40x+25
64x^2−48x+9
A difference of squares must be a binomial, so we want two terms. This rules out the third and fourth options.
If we look at the first two, we must check that both terms are perfect squares.
Look at the first one: [tex]4x^2[/tex] is a perfect square (it's [tex](2x)^2[/tex]), but [tex]10y^2[/tex] is not a perfect square, because 10 is not a perfect square.
On the other hand, if we look at the second option, [tex]16y^4[/tex] is the square of [tex]4y^2[/tex], and [tex]x^2[/tex] is clearly the square of [tex]x[/tex]. So, this is the difference of two squares.
Forty-two of the students in band own their instrument.
if this is $37.5% of the Students in the band, how many total
students are in the band?
Answer:
112 students
Step-by-step explanation:
Let T be the total number of students in the band.
From the question,
We were told that 37.5% of the total owns their individual instruments and this amount to 42 students
The total number of students can calculated for as follows:
37.5% x T = 42
37.5/100 x T = 42
Cross multiply to express in linear form
37.5 x T = 100 x 42
Divide both side by 37.5
T = (100 x 42) /37.5
T = 112
Therefore, there are 112 students in the band

The powers of 2 that are in the range 2 through 1,000 are 2, 4, 8, 16, 32, 64, 128, 256, and 512. Find all the powers of 3 that are in the range 3 through 1,000.
Final answer:
The powers of 3 that fall within the range of 3 through 1,000 are 3, 9, 27, 81, 243, and 729.
Explanation:
To find all the powers of 3 that are in the range 3 through 1,000, we need to calculate successive powers of 3 until the result exceeds 1,000. These calculations give us 31=3, 32=9, 33=27, 34=81, 35=243, 36=729, and 37=2187. However, since 2187 is greater than 1,000, we exclude it from our list. Therefore, the powers of 3 that fall within the specified range are 3, 9, 27, 81, 243, and 729.

Help me find the missing angles
Answer:
b) 105°
d) 130°
Step-by-step explanation:
An external angle has the same measure as the sum of the remote internal angles.
b) ? = 25° +80° = 105°
d) ? = 35° +95° = 130°
_____
This should be fairly obvious if you consider that the adjacent internal angle together with the external angle totals 180°, and the adjacent internal angle together with the other two internal angles totals 180°.
If the two "remote" angles are A and B, and the adjacent internal angle is C, then we have in symbols ...
A + B + C = 180° = ? + C
If we subtract C, then we find ...
A + B = ? . . . . . . the fact we used above

3. Which table is an example of exponential growth? (SEE PICTURE)
a. fun island
b. Great island
c. mystery island
4. How can you determine if a table is a linear function or an exponential function?
1.
Answer: D) rapid spread of diseaseChoice A is not exponential growth or decay because the cost will go up by the same amount ($2) each time. Choices B and C are exponential, but they aren't growth functions. Rather, they are decay functions. A disease spreads exponentially because one person infects two, and then each of those two people infect two others (making 4 additional people infected), and so on.
===============================
2.
Answer: C) number of cancer cells over time with treatmentAssuming the treatment works and it is effective, then the cancer cells will go away over time. One example would be that the population is cut in half each time. Choice A is not an answer because the balance will go down the same amount each time. This is assuming the bus company does not change its prices. Choices B and D are eliminated because they represent growth.

If the y values increase or decrease by the same amount, as x increases by some set amount, then you have a linear function. For example, if x increases by 1 pairs up with y increasing by 4, then the slope is 4/1 = 4 and we have a linear function.
--------
On the other hand, if x increases by 1 couples with the y values multiplying by some set amount, then you have an exponential function.
Example:
(x,y) = (1,2)(x,y) = (2,10)(x,y) = (3,50)Each time x increases by 1, y is multiplied by 5.

Find the MAD:
58, 38, 54, 48, 26, 36
Answer:
10.166666666667
Step-by-step explanation:
Answer:
(add up all the number and divide it by 6, cause there are about 6 numbers in the list)
58 + 38 + 54 + 48 + 26 + 36 = 260 ÷ 6 = 43.3
(subtract the mean {43.3} with the same listed numbers)
43.3 - 58 = 14.7
43.3 - 38 = 5.3
43.3 - 54 = 10.7
43.3 - 48 = 4.7
43.3 - 26 = 17.3
43.3 - 36 = 7.3
(add up all the difference and divide it with 6 again)
14.7 + 5.3 + 10.7 + 4.7 + 17.3 + 7.3 = 60 ÷ 6 = 10
so our MAD (mean absolute deviation) would be 10!

Kara rolled a number cube 10 times. The results of her rolls are shown
below.
1, 3, 3, 4, 6, 2, 2, 5, 3, 4
Based on Kara's results, what is the probability that her next roll
is either a 3 or 6?
Final answer:
The probability that Kara's next roll is either a 3 or a 6 is 1/3.
Explanation:
The question asks about the probability of rolling either a 3 or a 6 on a six-sided die based on previous rolls. The previous rolls are as follows: 1, 3, 3, 4, 6, 2, 2, 5, 3, 4. It is important to understand that each roll of a die is an independent event, meaning the outcome of one roll does not affect the outcomes of any other rolls.
Therefore, the results of Kara's previous rolls do not impact the probability of future rolls.
To determine the probability of rolling either a 3 or a 6, we consider that a six-sided die has six equally likely outcomes.
The probability of rolling a specific number, like a 3 or a 6, is therefore 1/6.
Since these are two separate outcomes, we add their individual probabilities to determine the probability of rolling either a 3 or a 6:
Probability of rolling a 3 = 1/6
Probability of rolling a 6 = 1/6
Total probability of either a 3 or 6 = 1/6 + 1/6 = 2/6 or 1/3.
Thus, the probability that Kara's next roll is either a 3 or a 6 is 1/3.

The following table shows the number of goals that the Texas Sharpshooters scored in each of their 8 hockey games this season.
Based on this data, what is a reasonable estimate of the probability that the Texas Sharpshooters score exactly 1 goal next hockey game?
3, 4, 1, 4, 1, 1, 2, 1
Answer:
The probability that the Texas Sharpshooters score exactly 1 goal next hockey game is 0.5
Step-by-step explanation:
The topic in question is Experimental probability;
Experimental probabilities deal with the probability of an event happening based on past experiments.
Given
Number of observation, n = 8
To calculate an estimate of the probability that the Texas Sharpshooters score exactly 1 goal next hockey game, we need to count the total occurrence of 1 in the given data
Let p = total occurrence of 1
p = 4
The probability is then calculated as [tex]\frac{p}{n}[/tex]

Probability = 0.5
Hence, The probability that the Texas Sharpshooters score exactly 1 goal next hockey game is 0.5
Why does (x-2)^2+9=0 have no real solutions?
Answer:
see explanation
Step-by-step explanation:
Given
(x - 2)² + 9 = 0 ( subtract 9 from both sides )
(x - 2)² = - 9 ( take the square root of both sides )
x - 2 = ± [tex]\sqrt{-9}[/tex]
[tex]\sqrt{-9}[/tex] yields no real solutions
There is no real number when multiplied by itself gives - 9
In fact the solutions to [tex]\sqrt{-9}[/tex] are said to be imaginary, that is ± 3i
where i = [tex]\sqrt{-1}[/tex]

Joe will go to the swimming pool on 20 different days this month.
• A one-day pass to the pool is $2.25.
• A monthly pass to the pool is $30.00.
How much money will Joe save by buying a monthly pass?
Answer:
He will save $15.00
Step-by-step explanation:
You multiply $2.25 by 20 days and that is equal to 45
So $45.00 - $30.00 that would be $15.00
If Joe buys a one-day pass for each of the 20 days he goes to the swimming pool this month, it will cost him $45.00. However, if he buys a monthly pass for $30.00, he will spend less money. Joe can save $15.00 by buying a monthly pass instead of a one-day pass each day.
Explanation:The subject of this question is mathematics as it involves arithmetic calculations to compare the cost of two possible options.
If Joe goes to the swimming pool 20 different days this month and buys a one-day pass for $2.25 every day, it would cost him 20 * $2.25 which equals to $45.00.
However, if Joe buys the monthly pass for $30.00, he would spend less money compared to buying a one-day pass every day. To find out how much Joe will save by buying the monthly pass, subtract the cost of the monthly pass from the total cost of buying one-day passes for 20 days. Therefore, $45.00 - $30.00 equals to $15.00.
So, Joe will save $15.00 by buying the monthly pass instead of a one-day pass each day he goes to the swimming pool.

111 = 14a This part is for the extra characters
The value of a = 7.93 or left as the fraction 111/14.
The question asks us to solve an algebraic equation for a single variable, specifically, solving 111 = 14a. This involves isolating the variable on one side of the equation to find its value. To do this, we divide both sides of the equation by 14, the coefficient of a.
Dividing both sides by 14, we get a = 111 / 14.
Thus, a = 7.928571429. However, for simplicity, we could round this to a = 7.93 or left as 111/14.
a car travels 90 miles in the same amount of time that a car traveling 10 mph slower travels 60 miles. find the speed of each car
Speed of the first car is 30 mph and that of the second car is 20 mph.
Step-by-step explanation:
Step 1: Let the speed of the first car be x mph. Then the speed of the second car = x - 10 mph. Distance traveled by the second car = 60 miles. Find the time taken by the second car to travel this distance.Time = Distance/Speed
= 60/x - 10 ------ (1)
Step 2: Find the time taken by the first car to travel given distance of 90 miles.Time = 90/x ------- (2)
Step 3: Given that both cars take the same amount of time, equate the 2 equations. (1) = (2)⇒ 60/x - 10 = 90/x
⇒ 60x = 90(x-10)
⇒ 2x = 3(x - 10)
⇒ 2x = 3x - 30
⇒ -x = -30
∴ x = 30 mph
⇒ x - 10 = 30 - 10 = 20 mph
