The cosine function repeats its pattern every 2π radians (or 360 degrees), we can say that the period of y = cos(x) is 2π.
The period of the function y = cos(x) is 2π.
To understand the period of the cosine function, we need to examine its graph. The cosine function is a periodic function that oscillates between -1 and 1 as x varies. It repeats its pattern over regular intervals.
The cosine function completes one full cycle from 0 to 2π radians (or 0 to 360 degrees). This means that within this interval, the cosine function goes through one complete oscillation, starting from its maximum value of 1, then going through its minimum value of -1, and returning back to 1.
Since the cosine function repeats its pattern every 2π radians (or 360 degrees), we can say that the period of y = cos(x) is 2π.
This means that for any value of x, the value of cos(x) will repeat after an interval of 2π.

Roger can run one mile in 9 minutes. Jeff can run one mile in 6 minutes. If Jeff gives Roger a 1 minute head start, how
long will it take before Jeff catches up to Roger? How far will each have run?
They each will have run of a mile.
It will take approximately 5.33 minutes for Jeff to catch up to Roger. Both Jeff and Roger will have run a distance of 1 mile.
Let's calculate the time it takes for Jeff to catch up to Roger and the distance each will have run.
First, we need to determine how much distance Roger covers during the 1-minute head start. Since Roger runs one mile in 9 minutes, in 1 minute, he would cover 1/9 of a mile.
Now, let's set up an equation to represent the time it takes for Jeff to catch up to Roger:
Distance covered by Jeff = Distance covered by Roger + Distance covered during the head start
Let's denote the time it takes for Jeff to catch up as t minutes. During this time, Jeff runs a distance of 1 mile, while Roger runs a distance of 1/9 of a mile (from the head start).
Distance covered by Jeff = Distance covered by Roger + Distance covered during the head start
1 mile = (1/9) mile + (6 minutes) × t × (1 mile/6 minutes)
Now, let's solve this equation to find the time it takes for Jeff to catch up:
1 = (1/9) + (1/6)t
Multiplying the equation by the least common multiple (LCM) of 9 and 6, which is 18, to clear the fractions:
18 = 2 + 3t
Subtracting 2 from both sides:
16 = 3t
Dividing by 3:
t = 16/3 = 5.33 minutes (rounded to two decimal places)
Therefore, it will take approximately 5.33 minutes for Jeff to catch up to Roger. Both Jeff and Roger will have run a distance of 1 mile.

A total of 90 groom's guests and 85 bride's guests attended a wedding. The bride's guests used 100 tissues. The groom's guests used 180 tissues. Calculate approximately how many tissues each groom's guest used.
Approximately 2 tissues were used by each groom's guest at the wedding.
The calculation is as follows:
180 tissues ÷ 90 guests = 2 tissues per guest.
To determine how many tissues each groom's guest used, we need to find the average number of tissues per guest. We start by adding up the number of tissues used by the groom's guests, which is 180.
Then, we divide this total by the number of groom's guests, which is 90. This division gives us an average of 2 tissues per guest.
By dividing the total number of tissues used by the total number of guests, we can find the average number of tissues per guest. In this case, each groom's guest used approximately 2 tissues.
It's important to note that this calculation assumes an equal distribution of tissues among all the groom's guests.

The veterinarian has prescribed carprofen 2.2 mg/kg BID x30d. Weight of patient is 34kg. Concentration is 75mg tablet. What is the amount of medication needed for 30 days?
The amount of medication needed for 30 days is approximately 59.84 tablets of carprofen.
To calculate the amount of carprofen medication needed for 30 days, we need to consider the prescribed dosage, the weight of the patient, and the concentration of the tablets.
The prescribed dosage is 2.2 mg/kg BID x 30d. This means that the patient should take 2.2 milligrams of carprofen per kilogram of body weight, twice a day, for 30 days.
The weight of the patient is 34 kilograms. So, we need to calculate the total amount of carprofen needed for the entire treatment period.
First, we calculate the daily dosage by multiplying the weight of the patient (34 kg) by the prescribed dosage (2.2 mg/kg).
Daily dosage = 34 kg * 2.2 mg/kg = 74.8 mg/day.
Since the medication is prescribed twice a day, we multiply the daily dosage by 2 to get the total dosage per day.
Total dosage per day = 74.8 mg/day * 2 = 149.6 mg/day.
Finally, to find the total amount of medication needed for 30 days, we multiply the total dosage per day by the number of days.
Total medication needed = 149.6 mg/day * 30 days = 4488 mg.
Since the concentration of the tablets is 75 mg, we divide the total medication needed by the tablet concentration to find the number of tablets required.
Number of tablets needed = 4488 mg / 75 mg = 59.84.

-18x < -54
Divide both sides of the inequality by -18, remembering to flip the inequality sign:
x > (-54) / (-18)

A total of 60% of the customers of a fast food chain order a hamburger, french fries, and a drink. if a random sample of 15 cash register receipts is selected, what is the probability that less than 10 will show that the above three food items were ordered?
The probability that less than 10 out of 15 cash register receipts will show the three food items ordered is approximately 0.166.
To calculate the probability that less than 10 out of 15 cash register receipts show that the hamburger, french fries, and a drink were ordered, we can use the binomial probability formula. The formula for the probability of obtaining exactly k successes in n trials is:
P(X = k) = (nCk) * p^k * (1 - p)^(n - k)
where:
P(X = k) is the probability of obtaining k successes,
n is the number of trials,
p is the probability of success in a single trial, and
(nCk) is the binomial coefficient, which represents the number of ways to choose k successes out of n trials.
In this case, we want to find the probability of less than 10 out of 15 receipts showing the three food items ordered. We need to calculate the probabilities for k = 0, 1, 2, ..., 9, and sum them up.
Let's calculate the probabilities using the formula:
P(X < 10) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 9)
where:
n = 15 (number of trials),
p = 0.60 (probability of success, i.e., ordering hamburger, french fries, and a drink).
Using a binomial calculator or a statistical software, we can calculate each individual probability and then sum them up. The result will be the probability that less than 10 out of 15 receipts show the three food items ordered.
The probability that less than 10 out of 15 cash register receipts will show the three food items ordered is approximately 0.166.

The equation of the new function after shifting 6 units right and 4 units down is f(x) = (x + 6)² - 4.
If we are to apply the changes below to the quadratic parent function, F(x) = x², what is the equation of the new function, given that we are to shift 6 units to the right and 4 units down? We will approach this question by following the steps outlined below.
Step 1: Identify the parent function F(x) = x² and its transformations
Step 2: Write the equation of the new function
Step 3: Simplify the new equation of the function.Step 1: Identify the parent function F(x) = x² and its transformations
Here, we are given the quadratic parent function F(x) = x² and two transformations: shift 6 units right and shift 4 units down.
The general equation for the horizontal and vertical shifts of a quadratic function is given by:f(x) = a(x - h)² + k, where a, h, and k are constants.
The value of a determines the direction of opening of the parabola, while (h, k) represents the vertex of the parabola.
If a > 0, the parabola opens upwards, while a < 0, the parabola opens downwards. If the values of (h, k) are positive, the parabola is shifted right and up, respectively. On the other hand, if the values of (h, k) are negative, the parabola is shifted left and down, respectively.
Therefore, given the quadratic parent function F(x) = x² and two transformations: shift 6 units right and shift 4 units down, we can represent these changes by the following:
a = 1 (since the parabola opens upwards)h = -6 (since we are shifting the parabola 6 units to the right)k = -4 (since we are shifting the parabola 4 units down)
Step 2: Write the equation of the new function Now that we have identified the constants a, h, and k, we can write the equation of the new function as follows:f(x) = a(x - h)² + kf(x) = 1(x - (-6))² + (-4)Replacing the constants a, h, and k in the equation, we have:f(x) = (x + 6)² - 4
Step 3: Simplify the new equation of the function.f(x) = (x + 6)² - 4= (x + 6)(x + 6) - 4= x² + 12x + 36 - 4= x² + 12x + 32Therefore, the equation of the new function after shifting 6 units right and 4 units down is f(x) = x² + 12x + 32.

12y + 4y = 2016
16y = 2016
Divide both sides of the equation by 16
16y/16 = 2016/16
y = 126
Substitute y = 126 to equation 1
x = 2y
x = 2(126)

The arithmetic mean is calculated by summing all the values in the series and dividing by the total number of values. In this case, the sum of all the values is nx, and since there are n values, the arithmetic mean is (nx) / n = x. So, A.M = x.
Geometric Mean (G.M):
The geometric mean is calculated by taking the nth root of the product of all the values in the series. In this case, the product of all the values is x^n, and since there are n values, the nth root of x^n is x. So, G.M = x.
Harmonic Mean (H.M):
The harmonic mean is calculated by taking the reciprocal of the arithmetic mean of the reciprocals of all the values in the series. Since all the values are the same, the reciprocal of each value is 1/x. The arithmetic mean of the reciprocals is (1/x + 1/x + ... + 1/x) / n = (n/x) / n = 1/x. Taking the reciprocal of 1/x gives x. So, H.M = x.

Answer:
A. (2, 18, -19)
Step-by-step explanation:
To solve:
Z is the most suitable variable to remove first
Add the first equation to the second equation: (this conveniently removes both y and z)
(x+y-z) + (4x-y+z) = 1+9
Simplify
5x = 10
Solve
x = 2
Multiply the second equation by 2 and minus it to the third equation: (Solve for y)
2(4x-y+z) - (x-3y+2z) = 2(9) - (-14)
Simplify
8x-2y+2z-x+3y-2z=18+14
7x+y=32
Substitute using x=2
7(2) + y = 32
y = 32 - 14
y = 18
Now substitute x and y for their respective values into Equation 1
2 + (-18) - z = 1
Simplify
-z = 19
z = -19
So :
x = 2, y = 18 , z = -19

find surface area and volume
The surface area and volume of the composite solid is are 1720ft² and 3563.33 ft³ respectively.
What is volume and surface area of composite solid?The area occupied by a three-dimensional object by its outer surface is called the surface area.
The surface area of the solid = lateral area of pyramid + surface area of cuboid
lateral area of pyramid = 4 × 1/2 bh
= 4 × 1/2 × 10× 12
= 120×2 = 240 ft²
Surface area of the cuboid = 2( 100+ 320+ 320)
= 2( 740)
= 1480 ft²
Surface area of the composite solid = 240 + 1480
= 1720 ft²
Volume of the composite solid = volume of cuboid + volume of pyramid
volume of cuboid = 10×10×32 = 3200ft²
volume of pyramid = 1/3base area × height
height of the pyramid is calculated as;
diagonal of base = √ 10²+10²
= √200
= 14.14
h² = 13²-7.07²
h² = 169 - 49.98
h² = 119.02
h = 10.9 ft
Volume of pyramid = 1/3 × 100 × 10.9
= 363.33 ft³
Volume of the composite solid = 3200+363.33
= 3563.33 ft³

G
F
73° E
195°
The measure of the outside angle F indicated in the figure is 61 degrees,
What is the measure of angle GFE?The external angle theorem states that "the measure of an angle formed by two secant lines, two tangent lines, or a secant line and a tangent line from a point outside the circle is half the difference of the measures of the intercepted arcs.
Expressed as:
Outside angle = 1/2 × ( major arc - minor arc )
From the figure:
Major arc = 195 degrees
Minor arc = 73 degrees
Outside angle F = ?
Plug the value of the minor and major arc into the above formula and solve for the outside angle F:
Outside angle = 1/2 × ( major arc - minor arc )
Outside angle = 1/2 × ( 195 - 73 )
Outside angle = 1/2 × ( 122 )
Outside angle = 122/2
Outside angle = 61°
Therefore, the outside angle measures 61 degrees.
Option C) 61° is the correct answer.

The diagonal distance from home plate to third base is approximately √16,200 feet.
The correct answers are:
B. 90 feet
C. √16,200 feet
D. 180 feet.
In baseball, the bases are arranged in a square shape.
The distance between each base is 90 feet.
Therefore, the correct answer for the distance a player at first base has to throw to a player at third base is 90 feet (option B).
To find the diagonal distance from home plate to third base, we can use the Pythagorean theorem.
Since the area of the baseball field is a square, the diagonal distance represents the hypotenuse of a right triangles.
The two legs of the right triangle are the sides of the square, which are 90 feet each.
Using the Pythagorean theorem [tex](a^2 + b^2 = c^2),[/tex] we can calculate the diagonal distance:
a = b = 90 feet
[tex]c^2 = 90^2 + 90^2[/tex]
[tex]c^2 = 8,100 + 8,100[/tex]
[tex]c^2 = 16,200[/tex]
c = √16,200 feet (option C)
Therefore, the diagonal distance from home plate to third base is approximately √16,200 feet.
The options A, √180 feet, and 180 feet are incorrect because they do not represent the correct distances in the given scenario.

Identify the algebraic rule that would translate a figure 3 units left and 2 units up.
The algebraic rule for translating the figure 3 units left and 2 units up is (x-3, y+2). Option B.
To translate a figure 3 units to the left and 2 units up, we need to adjust the coordinates of the figure accordingly. The algebraic rule that represents this translation can be determined by examining the changes in the x and y coordinates.
When we move a figure to the left, we subtract a certain value from the x coordinates. In this case, we want to move the figure 3 units to the left, so we subtract 3 from the x coordinates.
Similarly, when we move a figure up, we add a certain value to the y coordinates. In this case, we want to move the figure 2 units up, so we add 2 to the y coordinates.
Taking these changes into account, we can conclude that the algebraic rule for translating the figure 3 units left and 2 units up is (x-3, y+2). The x coordinates are shifted by subtracting 3, and the y coordinates are shifted by adding 2. SO Option B is correct.
