Answer:
4 a + 2 a^2 - 8 a^3 + 3 a^2 b - 12
Step-by-step explanation:
Simplify the following:
3 (b a^2 - 4) + a (-8 a^2 + 2 a + 4)
Hint: | Distribute a over -8 a^2 + 2 a + 4.
a (-8 a^2 + 2 a + 4) = -8 a^3 + 2 a^2 + 4 a:
-8 a^3 + 2 a^2 + 4 a + 3 (b a^2 - 4)
Hint: | Distribute 3 over a^2 b - 4.
3 (a^2 b - 4) = 3 a^2 b - 12:
Answer: 4 a + 2 a^2 - 8 a^3 + 3 a^2 b - 12
Z+k, when z=1 and k = 7
Answer:
8
Step-by-step explanation:
Replace the variables with numbers.
1+7=8
Answer:
8
Step-by-step explanation:
Since z equals 1 and k equals 7, we do 1 + 7 which is equal to 8. Therefore, the answer would be 8.
In ΔXYZ, z = 49 inches, ∠X=9° and ∠Y=108°. Find the area of ΔXYZ, to the nearest square inch.

Answer:
12 is your answer
Step-by-step explanation:
Heres how to find it:
How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
13+10+10+17+10=60
60/5=12

6
4.5
Answer:
4.5
Step-by-step explanation:
Answer:
4.5. Since you‘re dividing x by 4.5, multiply it by 4.5 to cancel the 4.5. Do the same with the other side.

Consider a student’s work in determining the solution set of x > 2(y – 1)^2 – 2.
Test point: (2.25, 1.25)
x > 2(y – 1)^2 – 2
2.25 > 2(1.25 – 1)^2 – 2
2.25 > 2(0.25)^2 – 2
2.25 > 2(0.0625) – 2
2.25 > 0.125 – 2
2.25 > –1.875
Conclusion: The point (2.25, 1.25) satisfies the given inequality.
Solution set:
Which element, if any, shows an error in the student’s work?
There are no errors.
The conclusion statement is incorrect.
The graph of the solution set is incorrect.
The substitution of x and y values is incorrect.
Answer:
C. The graph of the solution set is incorrect.Step-by-step explanation:
Solution is right, properly substituted x- and y-values, no mistakes. Conclusion is right, the point within the solution set. The only mistake is the graph, with > sign the line of the graph is not included into solution, therefore should be dotted.There are no errors.
Incorrect (the graph)The conclusion statement is incorrect.
IncorrectThe graph of the solution set is incorrect.
Correct (the line should be dotted)The substitution of x and y values is incorrect.

Find the volume of a right circular cone that has a height of 11.9 ft and a base with a radius of 16.3 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
3311.36ft^3
Step-by-step explanation:
Given data
Height h= 11.9ft
Radius=16.3ft
The expression for the volume of a cone is given as
Volume= 1/3πr^2h
substitute
Volume=1/3*3.142*16.3^2*11.9
Volume= 1/3*3.142*265.69*11.9
Volume= 1/3*9934.095962
Volume=3311.36ft^3
Hence the volume is 3311.36ft^3

how would i show work on this? A DATA set shows the number of minutes each of 153,477 students takes to complete a
reading test. The median completion time is 110 minutes. The interquartile range is 34. Which
statement about the completion times is most likely to be true?
Of these students, 25% complete the test in 110 minutes or less.
B. Of these students, 50% complete the test in 110 minutes or less.
C. Of these students, 75% complete the test in 127 minutes or less.
D. Of these students, 75% complete the test in 144 minutes or less.
Answer:
C
Step-by-step explanation:
half of IQR is 17
110 + 17 = 127 (this represents the 3rd quartile)
110 - 17 = 93 (this represents the 1st quartile)
The 3rd quartile represents 75% of the data so 75% of the students complete the test in 127 minutes or less

Which ordered pair is a solution of y = x - 4?
A: (3,-7)
B: (-3,-7)
C: (3,7)
D: (-3,7)
Answer:
The correct answer is (-3,-7). This is because you can plug it in and the two sides are equal to each other. When you plug -3 in for x, you subtract for from it and get -7 since the y term is -7 the answer is -7=-7, thus (-3, -7) is the answer.
