Answer:cot t = 1.875
[tex]sin t=\frac{-8}{17}[/tex] but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t
⇔cos t = [tex]\sqrt{1-sin^{2}t }=\sqrt{1-(\frac{-8}{17})^{2} }=|\frac{15}{17}|[/tex]
but t is a quadrant III angle => cos t = [tex]\frac{-15}{17}[/tex]
=> cot t = [tex]\frac{-15}{17}:\frac{-8}{17}=\frac{15}{8}=1.875[/tex]

My book is 79 pages. I have been reading 10 pages each day. There are 9 pages left to read. How many days have I been reading the book? Draw a model to show your thinking. Justify your answer.
Answers
Answer:
7 days
Step-by-step explanation:
If there are 9 pages left, that means you have already read 70 pages.
Since you read 10 pages a day, we can find how many days you have been reading the book by dividing 70 by 10:
70/10
= 7
This means you have been reading the book for 7 days
Answer:
7 days
Step-by-step explanation:
With 9 pages left take 79-9 to get 70 pages.
70 pages at 10 pages a day is 70/10 and you get 7 or 7 days.

Answers
Question is not very clear, however answers will reflect numbers seen(with some assumptions since some questions are not entirely complete)
Answer and explanation:
1. If a rectangle has an area of 35 meters and width of 78 meters, what is the length
Given that area of rectangle is length *width
Let's call length x
We have the equation
78*x=35
78x=35/78
x= 0.449
Therefore length =0.449 meters
2. Greg wants to divide a 712 yard long ribbon into pieces of 14 yard long each.
How many pieces can he make?
Let's assume the ribbon is a square then it's area is 712*712= 506944
To find number of 14 yard long pieces from the 712 yard long ribbon, we first find area for 14 yard long ribbons= 14*14= 196
number of 14 yard long pieces from the 712 yard long ribbon= 506944/196
= 2586.449 pieces
3. Olivia has 23 minutes an hour to write thank you notes. It takes her 12 minutes of an hour per thank you note. How many can she write?
Since it takes Olivia 12 minutes to write thank you notes but she has 23 minutes to write one, in one hour(1 hour =60minutes) she would be able to write
60 minutes /12 minutes = 5 thank you notes instead of
60 minutes /23 minutes= 2.609 or 2 thank you notes
4. Jim has 14 cups of nuts. How much of the recipe can he make?
If recipe requires 7 cups of nuts for instance, Jim would be able to make 14/7 = 2 of the recipe

Simplify this expression using the distributive property
Answers
Answer:
When you use the distributive property, you multiply the two numbers together, just like simplifying any product. You will also see another example where the expression in parentheses is subtraction, rather than addition. You will need to be careful to change the sign of your product.
Step-by-step explanation:
[tex]\huge\boxed{\bold{\mathfrak{Hello\;there!}}}}}[/tex]
The Distributive Property states that
[tex]\dashrightarrow[/tex] [tex]\bold{a(b+c)=ab+ac}[/tex]
[tex]\dashrightarrow[/tex] We multiply a by b and c, and then add the two products.
Example:
[tex]\dashrightarrow[/tex] [tex]\bold{10(x-3)}[/tex]

A golf ball is hit with an initial velocity of 80 ft/sec.Use the equation h(t)=80t-16t^2 where h(t) is the height of the object in feet and t is the time in seconds. How long will it take for the ball to hit the ground?
Answers
Answer:
The ball takes 5 seconds to hit the ground
Step-by-step explanation:
The equation to model the height of a golf ball in time t is:
[tex]h(t)=80t-16t^2[/tex]
There are two moments when the height is zero: At launch time and when it hits the ground. To find the last time, we equate:
[tex]80t-16t^2=0[/tex]
Factoring out t:
[tex]t(80-16t)=0[/tex]
It gives us two solutions:
t=0
[tex]80-16t=0[/tex]
Solving:
[tex]-16t=-80[/tex]
[tex]t=-80/(-16)=5[/tex]
t = 5 sec
Thus, the ball takes 5 seconds to hit the ground
The gross domestic product (GDP) of France is about $2.00 × 10 12 12 , and the GDP of Tuvalu is about $4.00 × 10 7 7 . How many times larger is the GDP of France than the GDP of Tuvalu?
Answers
Answer:
France's GDP is 50 000 times larger than Tuvalu's GDP.
Step-by-step explanation:
Given: Gross Domestic Product (GDP) of France = $2.0 x [tex]10^{12}[/tex]
Gross Domestic Product (GDP) of Tuvalu = $4.0 x [tex]10^{7}[/tex]
To determine the number of times in which the GDP of France is greater than that of Tuvalu, divide the GDP of France by the GDP of Tuvalu.
[tex]\frac{2.0*10^{12} }{4.0*10^{7} }[/tex] = [tex]\frac{2000000000000}{40000000}[/tex]
= [tex]\frac{200000}{4}[/tex]
= 50000
Therefore, France's GDP is 50 000 times larger than Tuvalu's GDP.

Look at the multiples of four that have an even number in the tens place. What value do they have in the one's place do you think this pattern? Would continue with multiples of four that larger than 100?
Answers
The multiples of 4 in the tens place are:
12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, . . .
The ones with even number in the tens place are:
20, 24, 28, 40, 44, 48, 60, 64, 68, 80, 84, 88, ...
In the ones value we see the pattern 0, 4, 8
Repeating itself.
And if you should continue for multiples of 4 greater than 100, this pattern will still continue.

Evan is going to the county fair this weekend. The admission to the fair is $5 and the cost per ride is $.50. Write and solve a linear equation to find out how many rides he can go on.
Answers
Answer:
Evan can go on 30 rides (based on the assumption that Evan's parent gave him $20)
Step-by-step explanation:
Given that:
The admission to the fair = $5
The cost per ride = $0.50
Let assume that the number of ride Evan can go = x
So if The cost per ride = $0.50
x ride = $0.50x
We are not told that he is given money by anybody, but let assume his parent gave him $20,
Then, if Evan pays $5 for admission into the fair. Then he will have $(20-5) = $15 left
The relation expressing how many rides Evan can go is:
0.5x = 15
Since the cost per ride = $0.5
x rides cost $15/0.5
x = 15/0.5
x = 30
Hence, Evan can go on 30 rides

Answer:
[tex]\left(g/f\right)\left(x\right)=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}[/tex]
Step-by-step explanation:
[tex]f(x)=4x+1[/tex]
[tex]g\left(x\right)=x^2\:-\:5[/tex]
As
(g/f)(x) = g(x) / f(x)
[tex]=\:\frac{x^2\:-\:5}{4x+1}\:\:\:\:\:\:[/tex]
[tex]=\frac{x}{4}+\frac{-\frac{x}{4}-5}{4x+1}[/tex]
[tex]=\frac{x}{4}-\frac{1}{16}+\frac{-\frac{79}{16}}{4x+1}[/tex]
[tex]=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}[/tex]
Therefore,
[tex]\left(g/f\right)\left(x\right)=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}[/tex]
