Answer:
Quotient = 70
Remainder = 50
Step-by-step explanation:
The greatest number you can make is 9210, the smallest 3-digit number is = 129.
9210 / 129 = 71 with 50 left
so:
70 is the quotient and 50 is the remainder
Given that Cos0=5/13,find a)Tan0,b)Sin0,c)Sec0,d)Co sec0,e)Cot0,
cos θ = Adjacent/ hypotenuse
cosθ= 5/13
a²+b²= c²
a² + 5² = 13²
a² = 13² - 5²
a² = 144
a=√144

a is the opposite = 12
b is the Adjacent = 5
c is the hypotenuse = 13
a) tan θ= opposite/Adjacent
tan θ = 12/5
b) sin θ= opposite/ hypotenuse

Solve for x using "Completing the Square"
Answer:
[tex]x=-7,-3[/tex]
Step-by-step explanation:
Completing the square means you are changing the polynomial so that it is a perfect square trinomial. Since the middle term is 10, we need the last term to be 25 since 5+5=10, thus, 5*5=25:
[tex]x^2+10x+21=0\\x^2+10x+21+4=0+4\\x^2+10x+25=4\\(x+5)^2=4\\x+5=\pm2\\x=-7,-3[/tex]
As you can see, because we change [tex]x^2+10x+21[/tex] to [tex]x^2+10x+25[/tex] by adding 4 to both sides, we were able to reduce it to [tex](x+5)^2[/tex], a perfect square, and solve the rest of the problem.

Charles decided that his old car could not make a 1200 mile trip; it might break down. Rather than take a chance on a big repair bill, and breaking down on the road, he decided to rent a car. The rental is $99 for a special three day weekend rate, with unlimited miles. If the rental car gets 30 miles per gallon and Charles has to pay $3.85 per gallon for gas, what is the total cost of gasoline and rental for the trip
Using proportions, it is found that the total cost of gasoline and rental for the trip is of $253.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the total cost is composed by:
The rental fee of $99.The gasoline cost, of $3.85 per gallon, considering that 1200/30 = 40 gallons were used.Hence, the total cost is given by:
C = $3.85 x 40 + $99 = $253.

1. Suppose three companies A, B and C dominate the market for a certain product and are
competing against each other for a large share of the market. Currently company A has 2/9 of the
market, company B has 4/0 of the market and company C has 1/3 of the market. The market
survey indicates that every 6 months Company A retains of its customer and loss 1/6 to
company B and 1/12 to company C. Company B retains 12 of its customers and loss 1/3 to
company A and 1/6 to company C. Company C retains 3/8 of its customers and loss A to
company A and 3/8 to company B. Find the market share of each company in the long run is
about
The market share of the companies is an illustration of fractions.
The market share of each company in the long run (i.e. after 6 months) is 37/108, 35/216 and 1/108, respectively
How to determine the market shares in the long runThe current market shares are:
Company A = 2/9Company B = 4/9Company C = 1/3After 6 months, we have:
Company A:
Retains 3/4Losses 1/6 to BLosses 1/12 to CCompany B:
Retains 1/2Losses 1/3 to ALosses 1/6 to CCompany C:
Retains 3/8Losses 1/4 to ALosses 3/8 to BThe amount of customers lost by each company is
Lost = Market share * [Share retained - Share lost to the other two companies].
So, we have:
A = 2/9 * [3/4 - 1/6 - 1/12] = 1/9
B = 4/9 * [1/2 - 1/3 - 1/6] = 0
C = 1/3 * [3/8 - 1/4 - 3/8] = -1/12
The amount of customers gained by each company is
Gain = Market share of company gained from * Share gained
So, we have:
A = 1/3 * 4/9 + 1/4 * 1/3 = 25/108
B = 1/6 * 2/9 + 3/8 * 1/3 = 35/216
C = 1/12 * 2/9 + 1/6 * 4/9 = 5/54
The total gain in 6 months is:
Total Gain = Gain + Loss.
This gives
A = 25/108 + 1/9 = 37/108
B = 35/216 + 0 = 35/216
C = 5/54 - 1/12 = 1/108
Hence, the market share of each company in the long run (i.e. after 6 months) is 37/108, 35/216 and 1/108, respectively

Find the volume please help I don't understand.
By dividing the figure into a rectangular prism and a pyramid, we will see that the total volume is 2,400 ft^3
How to find the volume?
We can divide the given figure into two simpler ones.
A rectangular prism of 20 ft by 10 ft by 10 ft, whose volume is the product of these dimensions:
V = 20ft*10ft*10ft = 2,000 ft^3
And a pyramid of 4 sides, with a height of 6ft and a base of 20ft by 10ft, and we know that the volume of the pyramid is one-third of the product between the base and the height.
V' = (1/3)*6ft*(20ft*10ft) = 400ft^3
Then the total volume of the given figure is:
volume = V + V' = 2,000ft^3 + 400ft^3 = 2,400 ft^3

Julia has 2 chemistry books and 3 math books. In her rush to get to class, she grabs two books without stopping to look. What is the probability that she pulls out a math book and a chemistry book?
Answer:
P(M &C) = 0.24
Step-by-step explanation:
Chemistry book will be denoted by C
Mathematics book will be denoted by M
5C2 = 10
There are 10 possible ways in which she can choose two books from the 5 books.
The probability of choosing a chemistry book:
P(C) = 2/5
The probability of choosing a mathematics book:
P(M) = 3/5
Probability of choosing a chemistry book and a mathematics book:
P(M &C) = (2/5) × (3/5)
P(M &C) = 0.24 or 24%
The probability that she pulls out a math book and a chemistry book will be 0.24.
What is mean by Probability?The term probability refers to the likelihood of an event occurring
Given that;
Julia has 2 chemistry books and 3 math books.
Now,
Since, Julia has 2 chemistry books and 3 math books.
Hence, Total number of books = 2 + 3 = 5
So, The probability to choosing a chemistry book = 2/5
And, The probability to choosing a math book = 3/5
Thus, The probability that she pulls out a math book and a chemistry book is,
⇒ 2/5 × 3/5

Step-by-step explanation:
The domain of any polynomial is "all real numbers." The domain of any rational function excludes any values of the variable that result in the denominator being 0. The function is "undefined" there.

The values x=-5 and x=-3/2 make the denominator of v(x) become 0, so those values are excluded from the domain of v(x). The function is "undefined" when its denominator is zero.

Additional comment
The numerator and denominator factors (x+5) cancel each other, so there is no vertical asymptote at x=-5. Rather, the function has a "hole" there, where it is undefined. The limit as the function approaches x=-5 from either direction is v(x) = 10/7.

You can get an idea of what the 90° rotation looks like by printing the figure and turning it 1/4 turn counterclockwise. The points will have the same relative locations with respect to the axes. Effectively, you are relabeling the x-axis to y, and the -y axis to x. (That is what the 90° CCW transformation formula is telling you.)
Alternatively, you can turn your head sideways when you look at the computer screen.
In the attachment, the black arrow represents the translation vector, 7 left and 8 down.
