Show all work to multiply quantity 3 plus the square root of negative 16 end quantity times quantity 6 minus the square root of negative 64 end quantity (10 points)
Answer:
50Step-by-step explanation:
Quantity 3 plus the square root of negative 16 end quantity:
3 + √-16Quantity 6 minus the square root of negative 64 end quantity:
6 - √-64Multiply the two above:
(3 + √-16)(6 - √-64) = (3 + 4√-1)(6 - 8√-1) = (3 + 4i)(6 - 8i) = 3*6 - 3*8i + 6*4i - 4i*8i = 18 - 24i + 24i - 32i² = 18 - 32(-1) = 18 + 32 = 50Referring to the figure, is the transformation a
rotation about the origin?

The last one is the answer.
Step-by-step explanation:
Inverses are like opposites so [tex]\sqrt{x}[/tex] would be the inverse of [tex]x^{2}[/tex]. However don't be fooled by the second option because that is not the same although it seems like it. The true inverses are [tex]\sqrt[3]{27}[/tex] and [tex]3^{3}[/tex]. 3 cubed is 27 and the cube root of 27 is 3.

Gymnast Clothing manufactures expensive hockey jerseys for sale to college bookstores in runs of up to 150. Its cost (in dollars) for a run of x hockey jerseys is
C(x) = 1500 + 10x + 0.2x2 (0 ≤ x ≤ 150)
1. Gymnast Clothing sells the jerseys at $90 each. Find the revenue function.
2. Find the profit function.
3. How many should Gymnast Clothing manufacture to make a profit?
The Revenue function for the number of jerseys x sold is ; R(x) = 90x
The profit function from the sale of x jerseys is ; P(x) = - 0.2x² + 80x - 1500
The number of Jerseys to manufacture in other to make profit = 20
The revenue made is the total amount made from the sale of the hickey jerseys :
Sales price per jersey = $90
Hence, the revenue made, R(x) = 90x
The Cost function, C(x) = C(x) = 1500 + 10x + 0.2x²
Recall :
Profit = Revenue - Cost
Hence,
P(x) = R(x) - C(x)
P(x) = 90 - (0.2x² + 10x + 1500)
P(x) = 90 - 0.2x² - 10x - 1500
P(x) = - 0.2x² + 80x - 1500
To make profit, equate P(x) to 0 ;
0.2x² - 80x + 1500 = 0
Using a quadratic calculator :
x = 380.22 or x = 19.72
Hence, to make a profit, the number of jerseys that must be sold is 20.

A nurse mixes 40 cc of a 70% saline solution with a 20% saline solution to produce a 36% saline solution. How much of the 20% solution should he use?
00
The amount of 20% saline solution needed is
CC.
B
We will need 85cc of 20% saline solution for the mixture
Let the amount of 20% saline solution be "a"
If a nurse mixes 40 cc of a 70% saline solution with a 20% saline solution to produce a 36% saline solution, then the finished product will be 40 + a cc which containing 36% saline solution.
The saline content will therefore be expressed as:
(70% of 40)+20% of a = 36% of (40 + a)
0.7*40 + 0.2a = 0.36(40 +a)
28 + 0.2a = 14.4+0.36a
28 - 14.4 = 0.36a - 0.2a
13.6= 0.16a
a = 13.6/0.16
a = 85
This means that we will need 85cc of 20% saline solution for the mixture

The value of a car dropped from $23,600 to $21,900 over the last year. Determine the actual and relative change in this situation.
Actual Change: ? This car's value decreased by $
last year.
Round your answer to the nearest dollar.
Relative Change: ? This car's value decreased by
% last year.
Round your answer to the nearest tenth of a percent.
Answer:
The actual change in the car's value is $[tex]1700[/tex] and the relative change is [tex]7.20[/tex]%.
Step-by-step explanation:
It is given that the value of a car is dropped from $[tex]23600[/tex] to $[tex]21900[/tex].
So, the change in the value is the drop in the value of car, which is, [tex]23600-21900=1700[/tex].
So, the actual change in this car's value is $[tex]1700[/tex].
The relative change can be given by the expression,
[tex]\dfrac{\:\rm{Actual Change}}{\:\rm{Original Value}}\times100[/tex]
Substituting values, the relative change can be given by,
[tex]\begin{aligned}\dfrac{1700}{23600} \times 100&=\dfrac{1700}{236}\\&=7.20\end{aligned}[/tex]
If (5^4)m = 5^12, what is the value of m? (4 points)
A. 2
B. 3
C. 5
D. 8
Answer:
The value of m is 3
Step-by-step explanation:
(5^4)m =5^12
M = 3
(5^4)3 =5^4*3=12
(5^4)3 = 5^12
Answer:
(5 ^4)^m = (5)^12
625^m = (5)^12
Taking logs of both sides
log(625) *m = log (5) *12
m = log (5) *12 / log(625)
m = 0.69897000434 * 12 / log (625)
m = 0.69897000434 * 12 / 2.7958800173
m = 0.69897000434 * 12 / 2.7958800173

0.35 is hundredth, and since you always round 5 up, it makes 0.4
Answer:
0.4
Step-by-step explanation:
To figure out the answer, first we need to know how to round. Find the tenths place. That's the first 3 you come upon. Look at the number beside it. It is a five which means you would round up (this is because of the 5 or more raise the floor, four or less let it rest rule) The 3 would then turn into a 4.

Answer:
8: thousands place, 5,000
9: millions place, 6 million
Step-by-step explanation:
Place value is quite confusing at first, but it gets to be much easier. Basically, every time you add a place on a number, you are increasing its place value! Lets use number 9 for example. The one in this number is in the ones place. You know this because it is the last digit. The 4, is the tens place, since it is directly to the left of the ones place. You are increasing the place value to the left. The order of place value is:
Ones
Tens
Hundreds
Thousands
Ten thousands
Hundred thousands
Millions
Ten Millions
Hundred Millions
Billions
and so on. I hope this was helpful!
