9. Expand using identites.
1) (3/2 m - 5n) (3/2 m + 5n)
Answer:
(3/2 m)^2 -(5n)^2^
Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:
Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.

11ピースのスライスチーズが入ったパッケージの価格は2.97ドルです。
18スライスのパッケージは、スライスあたり同じ価格でいくらかかりますか?あなたの理由を説明または示してください。
Answer:
$4.86
Step-by-step explanation:
The package of cheese that cost $2.97 has 11 slices. To know how much each slice costs, we need to divide $2.97 by 11.
That is $2.97/11 = $0.27 per slice
Now we need to calculate how much would cost a package of 18 slices with the same price per slice.
As we now know that each slice costs $0.27, we just need to multiply 18 by $0.27 to know the total price.
That is 18*$0.27 = $4.86
A package with 18 slices would cost $4.86.
Solve the equation t − 3 = 17 for t.
−20
20
−14
14
The value of t = 20
This is the given Equation:
t - 3 = 17
Now we have to take (-3) from the left to right side to determine the value of t.
It will change the sign of 3.
t = 17 + 3
t = 20
So, the value of 't' in the given Equation is 20.

The table below represents the number of math problems Jana completed as a function of the number of minutes since she began doing her homework. Does this situation represent a linear or non-linear function, and why?
Answer:
D. The right side is not a linear function.
Step-by-step explanation:
In order for it to be linear. Both sides need to be linear meaning a constant rate of change.
Jaha has designed a rocket. She determines the initial velocity of her rocket is 36 meters per second. She uses the function h(t) = - 9.8t ^ 2 + 36t to find the height, h(t) based on time, t, in seconds. Jana wants to know approximately when her rocket will be at the following heights:
24 Meters
36 Meters
To find when the rocket will be at a certain height, we can set the equation for height, h(t), equal to the given height and solve for t.
For 24 meters:
-9.8t^2 + 36t = 24
-9.8t^2 + 36t - 24 = 0
We can solve for t using the quadratic formula:
t = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = -9.8, b = 36, and c = -24. Plugging in these values, we get:
t = (-36 ± sqrt(36^2 - 4(-9.8)(-24))) / 2(-9.8)
t ≈ 1.87 seconds or t ≈ 3.14 seconds
So the rocket will be at a height of 24 meters approximately 1.87 seconds after launch and again approximately 3.14 seconds after launch.
For 36 meters:
-9.8t^2 + 36t = 36
-9.8t^2 + 36t - 36 = 0
Using the quadratic formula again, we get:
t = (-36 ± sqrt(36^2 - 4(-9.8)(-36))) / 2(-9.8)
t ≈ 1.16 seconds or t ≈ 3.66 seconds
So the rocket will be at a height of 36 meters approximately 1.16 seconds after launch and again approximately 3.66 seconds after launch.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
