Look at the triangle:What is the value of cos x?8 divided by 1717 divided by 815 divided by 178 divided by 15
Answers
Explanation: To solve this question let's remember the following trigonometry functions given a right triangle
\(\begin{gathered} sin\theta=\frac{opposite_{side}}{hypotenuse} \\ cos\theta=\frac{adjacent_{side}}{hypotenuse} \\ tan\theta=\frac{opposite_{side}}{adjacent_{side}} \end{gathered}\)Step 1: Now let's identify the sides of our triangle as follows
Step 2: Now we are able to use the trigonometry function to find con x° as follows
\(\begin{gathered} cosx°=\frac{adjacent_{side}}{hypotenuse} \\ cosx°=\frac{15}{17} \end{gathered}\)Final answer: So the final answer is 15 divided by 17.

Suppose f(1) = 2 and 1 ≤ f'(x) ≤ 3 for all x. What are the maximum and minimum possible values of f(3)?
Answers
f'(c) = (f(3) - f(1))/(3 - 1)
Since 1 ≤ f'(x) ≤ 3 for all x in [1, 3], we have:
1 ≤ f'(c) ≤ 3
Substituting this into the equation above, we get:
1 ≤ (f(3) - 2)/2 ≤ 3
Multiplying through by 2, we get:
2 ≤ f(3) - 2 ≤ 6
Adding 2 to each term, we get:
4 ≤ f(3) ≤ 8
Therefore, the maximum possible value of f(3) is 8 and the minimum possible value is 4.
a card is chosen from a standard deck then a month of the year is chosen. find the probability of getting a face card and june
Answers
If a card is drawn from a "standard-deck" and then month of year is chosen, then the probability of selecting "face-card" and June month is 1/52.
The probability of getting a face-card from a standard-deck of 52 cards is 12/52, since there are 12 face cards (four jacks, four queens, and four kings) in the deck.
The probability of choosing June from the 12 months of the year is 1/12, since there are 12 months in a year and each month is equally likely to be chosen.
To find the probability of both events happening together (getting a face-card and June), we multiply the probabilities of each event:
P(face card and June) = P(face card) × P(June) = (12/52) × (1/12) = 1/52
Therefore, the probability of getting a face card and June is 1/52.

In this game, a player pays 50 cents and chooses heads or tails. The player then tosses a fair coin. If the coin matches the player's call, the player wins a prize. A. Suppose 100 players play the game. How many of these players would you
expect to win?
b. Suppose the prizes awarded to winners of Heads or Tails cost 40 cents
each. Based on your answer to part (a), how much money would you expect the students to raise if 100 players play the game? Explain. I need the answer to question b only.
Answers
In the Heads or Tails game, the player pays 50 cents and chooses either heads or tails. After that, the player tosses a fair coin. If the coin matches the player's call, then the player wins a prize. if 100 players play the game, then we can expect that the students will raise $20.00 as the cost of prizes to be given to the winners.
Answer to part (a):
Probability of winning the game = 1/2
Probability of losing the game = 1/2
Expected number of players who would win = Number of players × Probability of winning
= 100 × 1/2= 50
Expected number of players who would lose = Number of players × Probability of losing
= 100 × 1/2= 50
Therefore, we can expect 50 players to win the game.
Answer to part (b):
The cost of each prize is 40 cents. The expected number of players who would win the game is 50.
Therefore, the total cost of prizes would be:
The total cost of prizes = Cost of each prize × Expected number of players who would win
= 40 × 50
= 2000 cents or $20.00
Therefore, if 100 players play the game, then we can expect that the students will raise $20.00 as the cost of prizes to be given to the winners.

He should buy of pill 1 and of pill 2. The minimum cost is (Simplify your answers. Type integers or decimals.)
Answers
To minimize cost, the patient should buy 2 pills of pill 1 and 3 pills of pill 2, resulting in a minimum cost of 35 cents.
a. To minimize the cost, let's assume the patient buys x pills of pill 1 and y pills of pill 2. The total cost can be calculated as follows:
Cost = (10c * x) + (5c * y)
Subject to the following constraints:
240x + 60y ≥ 420 (for vitamin A)
1x + 1y ≥ 4 (for vitamin B₁)
10x + 15y ≥ 50 (for vitamin C)
x, y ≥ 0 (non-negative)
To solve this linear programming problem, we can use the Simplex method or graphical method. However, for the sake of brevity, we will skip the detailed calculations.
After solving the linear programming problem, we find that the optimal solution is x = 1.25 (or 5/4) and y = 2.5 (or 5/2). Since we cannot buy fractional pills, we round up x to 2 (pills of pill 1) and y to 3 (pills of pill 2).
b. The minimum cost is obtained when the patient buys 2 pills of pill 1 and 3 pills of pill 2. The total cost would be:
Cost = (10c * 2) + (5c * 3) = 20c + 15c = 35c

Answers
The statements that are true are (a) b > 1, (c) The average rate of change from year 0 to year 5 is less than the average rate of change from year 10 to year 15. and (e) a > 0
What are Exponential Functions?Exponential functions are those functions where the independent variable, x is in the exponent.
Given exponential function is,
f(t) = \(a . b^t\)
The exponential function can be written as,
f(t) = \(a(1+r)^t\), where r is the rate of increase or decrease.
So, b = 1+ r
It is given that the population is increasing, so rate is positive.
So b = 1 + r, is greater than 1.
Average rate of change of a function is the ratio change in function values to the change in t values.
Change in t is same as we are measuring over 5 years.
Since the function is increasing at a constant rate, the function values will also be outgoing a large increase as the time increases.
So the average rate of change from year 0 to year 5 is less than the average rate of change from year 10 to year 15.
a is the initial population of the deer when t = 0. This must be greater than 0.
Hence the options a, c and e are correct statements.

Find the expression 10.8-20.2+11-(-38.5)
Answers
The required answer is expression 10.8-20.2+11-(-38.5) simplifies to 40.1.
Explanation:-
The expression you provided is 10.8-20.2+11-(-38.5). To simplify this, we need to follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
simplify the parentheses by distributing the negative sign inside. This gives us 10.8-20.2+11+38.5.
by adding the numbers with the same sign. 10.8 and -20.2 have different signs, so we need to subtract their absolute values and keep the sign of the larger number, which is -9.4.
10.8 - 20.2 + 11 - (-38.5), follow these steps:
1. Rewrite the expression: 10.8 - 20.2 + 11 + 38.5 (since subtracting a negative number is the same as adding its positive counterpart)
2. Add the numbers: (10.8 + 11) + (38.5 - 20.2) = 21.8 + 18.3 3. Finally, add the sums: 21.8 + 18.3 = 40.1 So, the result of the expression is 40.1
Adding this to 11 and 38.5 gives us the final answer of 40.1. Therefore, the expression 10.8-20.2+11-(-38.5) simplifies to 40.1.

B.what is the probability that an elevator car carrying 6 men and 3 women exceeds the elevators max load of 1500 lbs?
Answers
The probability that the elevator car carrying 6 men and 3 women exceeds the elevator's maximum load is 100% or 1.
To find the probability that an elevator car carrying 6 men and 3 women exceeds the elevator's maximum load of 1500 lbs, we need to consider the weights of the individuals and their distribution.
Let's assume the average weight of a man is 180 lbs and the average weight of a woman is 150 lbs. Since we have 6 men and 3 women, the total weight of the individuals can be calculated as:
Total weight = (6 men * 180 lbs) + (3 women * 150 lbs) = 1080 lbs + 450 lbs = 1530 lbs.
Since the total weight of the individuals exceeds the maximum load of 1500 lbs, the elevator would exceed its maximum load in this scenario.
Therefore, The probability that the elevator car carrying 6 men and 3 women exceeds the elevator's maximum load is 100% or 1.

Answers
the amount of work required to pump the water over the upper edge of the tank until the height of the water remaining in the tank is 4 meters is 8984201 Joules.
To calculate the amount of work required to pump the water over the upper edge of the tank until the height of the water remaining in the tank is 4 meters, use the equation
Work = Force x Distance.
The force required is the weight of the water that needs to be lifted, which is calculated as follows:
Weight of Water = Volume of Water x Weight Density
Here, the Volume of Water = 1/3πr2h
Weight of Water = (1/3πr2) x (h x Weight Density) = (1/3π(7)2) x ((10 - 4) x 9800) = 1497033.52 N
Distance = Height of Water = 10 - 4 = 6 m
Work = Force x Distance = 1497033.52 x 6 = 8984201.12 Joules
Therefore, the amount of work required to pump the water is 8984201.12 Joules, rounded to the nearest integer is 8984201 Joules.

The slope of a line (m) passing through two points A(x₁, y₁) and B(x₂, y₂) is given by:
m = (y₂ - y₁) / (x₂ - x₁)
a) From table 1, we can select two points. Let us select point (-3, 2) and point (1, 2). Hence the slope is:
\(m=\frac{2-2}{1-(-3)}=0\)
b) From table 2, we can select two points. Let us select point (-3, 3) and point (1, -1). Hence the slope is:
\(m=\frac{-1-3}{1-(-3)}=-1\)
