Answer:
First, we know that:
cot(x) = cos(x)/sin(x)
csc(x) = 1/sin(x)
I can't know for sure what is the exact equation, so I will assume two cases.
The first case is if the equation is:
[tex]\frac{cot(x)}{sin(x)} - csc(x)[/tex]
if we replace cot(x) and csc(x) we get:
[tex]\frac{cot(x)}{sin(x)} - csc(x) = \frac{cos(x)}{sin(x)} \frac{1}{sin(x)} - \frac{1}{sin(x)}[/tex]
Now let's we can rewrite this as:
[tex]\frac{cos(x)}{sin(x)} \frac{1}{sin(x)} - \frac{1}{sin(x)} =\frac{cos(x)}{sin^2(x)} - \frac{1}{sin(x)}[/tex]
[tex]\frac{cos(x)}{sin^2(x)} - \frac{sin(x)}{sin^2(x)} = \frac{cos(x) - sin(x)}{sin^2(x)}[/tex]
We can't simplify it more.
Second case:
If the initial equation was
[tex]\frac{cot(x)}{sin(x) - csc(x)}[/tex]
Then if we replace cot(x) and csc(x)
[tex]\frac{cos(x)}{sin(x)}*\frac{1}{sin(x) - 1/sin(x)} = \frac{cos(x)}{sin(x)}*\frac{1}{sin^2(x)/sin(x) - 1/sin(x)}[/tex]
This is equal to:
[tex]\frac{cos(x)}{sin(x)}*\frac{sin(x)}{sin^2(x) - 1}[/tex]
And we know that:
sin^2(x) + cos^2(x) = 1
Then:
sin^2(x) - 1 = -cos^2(x)
So we can replace that in our equation:
[tex]\frac{cos(x)}{sin(x)}*\frac{sin(x)}{sin^2(x) - 1} = \frac{cos(x)}{sin(x)}*\frac{sin(x)}{-cos^2(x)} = -\frac{cos(x)}{cos^2(x)}*\frac{sin(x)}{sin(x)} = - \frac{1}{cos(x)}[/tex]
A new field has a perimeter of 220 m and a width of 62 m. A bag of canola seed will cover 185 m2 of ground. How many bags of canola seed are needed to seed the new field?
52
16
53
17
Answer:
17
Step-by-step explanation:
Assuming the field is a rectangle, the perimeter is found through the equation:
[tex]P = 2l + 2w[/tex]
Since we know the perimeter and width, we can substitute and solve for the length.
[tex](220) = 2l + 2(62)\\220 = 2l + 124\\96 = 2l\\l = 48\\[/tex]
Using the length and width, we can find the area.
[tex]A = lw\\A = (48)(62)\\A = 2976[/tex]
The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.
[tex]n = 2976 / 185\\n = 16.09[/tex]
Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.

A credit card company advertises an APR of 17.2%, compounded daily. What is the effective interest rate
Answer:
18.76%
Step-by-step explanation:
effective interest rate = ( 1 + periodic interest rate)^m - 1
m = number of compounding = 365
Periodic interest rate = APR / number of compounding = 17.2 / 365 = 0.0471% = 0.000471
(1 + 0.000471) ^365 - 1 = 18.76%

a bag contains 10 marbles. Four of them are red, three blue, two white, and one yellow. A marble is drawn at random. What is the probability that it is red? Make sure to reduce your answer. 25 points if you answer help pls :/
Answer:
40% chance
Step-by-step explanation:
4 marbles out of 10 are red. 4/10= 0.4= 40%
Answer: 2/5
Step-by-step explanation: If there're 10 marbles and 4 of them are red, then the probability of it being red is 4/10.
To reduce or simplify it, you must divide both 4 and 10 by 2, leaving you with 2/5.

Answer:
BC ≈ 17.0 (neither Crow nor Toad is correct)
Step-by-step explanation:
The left-side ratio of (2+4)/4 = 3/2 suggests BC is 3/2 times the length DE. If that were the case, BC = (3/2)(11) = 16.5, as Crow says.
The right-side ratio of (5+9)/9 = 14/9 suggests that BC 9 is 14/9 times the length DE. If that were the case, BC = (14/9)(11) = 154/9 = 17 1/9 ≈ 17.1, as Toad says.
The different ratios of the two sides (3/2 vs 14/9) tell you that the triangles are NOT similar, so the length of BC cannot be found by referring to the ratios of the given sides.
Rather, the Law of Cosines must be invoked, first to find angle A (109.471°), then to use that angle to compute the length of BC given the side lengths AB and AC. That computation gives BC ≈ 16.971. (See the second attachment.)
ANSWER NOW PLEASE: Tom is having his car repaired. The cost of the parts is $260
and 4 hours of work are required. Tom needs to keep the
entire cost of the repair under $400. Which inequality
expresses the relationship between hourly cost (x), parts,
and the $400 limit?
Answer:
260 + 4x < 400
Step-by-step explanation:
To make our inequality, let's list out the separate costs we have, all of which combined should be less than 400.
First, we have the cost for the parts, which is $260. The other cost we have is the hourly rate for the work. The repair will take a certain amount of money for every hour worked. The rate must be low enough that it doesn't exceed $400 when combined with the $260 from the parts.
To construct our inequality, we can begin with the estalished $260.
Then, add to this the hourly rate, (x) times the number of hours worked, 4.
So we have-
260 + 4x
The total of this cost must be less than $400 dollars, so we will use the less than ( < ) sign in front of the 400.
260 + 4x < 400
The answer is 260 + 4x < 400. I hope this was helpful :] Good luck ^^
Nolan has some nickels and some dimes he has no more than 19 coins worth no less than $1.30 combined if Nolan has 5 nickels determine all possible values for the number of dimes that he could have
Answer:
10.5 ≤ y ≤ 14
Step-by-step explanation:
A nickel is worth 5 pennies. Changing over to dollars, it becomes
5/100 = $0.05
A dime is worth dime. Changing over to dollars, it becomes
10/100 = $0.1
Allow x to address the number if nickels.
Allow y to address the quantity of dimes.
He has close to 19 coins. This implies that
x + y ≤ 19
He has no under $1.30 joined. This implies that
0.05x + 0.1y ≥ 1.3
On the off chance that Nolan has 5 nickels, subbing x = 5 into x + y ≤ 19, it becomes
5 + y ≤ 19
y ≤ 19 - 5
y ≤ 14
subbing x = 5 into 0.05x + 0.1y ≥ 1.3, it becomes
0.05 × 5 + 0.1y ≥ 1.3
0.25 + 0.1y ≥ 1.3
0.1y ≥ 1.3 - 0.25
0.1y ≥ 1.05
y ≥ 1.05/0.1
y ≥ 10.5
Along these lines, all potential qualities for the quantity of dimes that he could have would be
10.5 ≤ y ≤ 14

9000 is perfect square number?
Step-by-step explanation:
no it's not.....
........
Answer:
no
Step-by-step explanation:
there should always be even number of 0 if it wants to be a perfect square.
3 * 3 =9
30 * 30 =900. .......(2 0's)
300 * 300 = 9000...(4 0's and so on)
9000 does not meet this criteria so it isn't a perfect square.

Meredith has two different-sized bags of trail mix. The larger bag contains 6.18 ounces of trail mix. The smaller bag contains more trail mix? Why
Answer:
The answer is "smaller bag ".
Step-by-step explanation:
Please find the complete question in the attached file.
There are more trail mixes in the smaller pack.
It's because in the smaller bag (6.8 ounces) the trail mix is more than in the bigger bag (6.18 ounces).
It was reasonable because the capacity of the bag is not stated, and both bags will contain far more than 6,8 ounces.

Answer:
1: The highest score is 98, the lowest score is 74.
2: 55% of the scores are greater than 84
Step-by-step explanation:
Solution 1-1:
Starting from the top left and going from left to right row by row we compare the largest number we come across with the current number we are inspecting.
Starting with 92 then we look at 88, 92 is greater than 88 so we keep 92, next is 95, 95 is greater than 92 so we keep 95, next is 74, 95 is greater than 74 so we keep 95 and so on until we have compared all of the numbers. We are left with 98
Solution 1-2:
Using a similar method to finding the greatest number we go through the list of numbers in search of the smallest number. Starting with 92 we then look at 88, 88 is less than 92 so we keep 88. Next is 95, 88 is less than 95 so we keep 88. Then 74, 74 is less than 88 so we keep 74 and so on. We are left with 74
Solution 2:
There is a total of 20 numbers in the table. By comparing the numbers in the table to 84, we can determine that 11 numbers are greater than 84.
By dividing 11 by 20 we get 0.55 which is equal to 55%
