The period of the given function is π/5. The option 4 is the correct option.
What is the period of the cosine function?
The cosine function is the trigonometric function, hence it is known as the periodic function.
The period of a function is the total interval in which the function repeats itself over and over again the of the function for a complete cycle. If,
[tex]f(x)=A\cos(Bx+C)+D[/tex]
Then the period of the cosine function can be given as,
[tex]I=\dfrac{2\pi}{|B|}[/tex]
Given information-
The given function in the problem is,
[tex]f(x)=\cos(10x)[/tex]
The above function is the cosine function. Let a cosine function of in with values of [tex]x[/tex] 0 to 2π.
Now the period of the periodic function is the interval of [tex]x[/tex] values in which the the cycle of graph repeats itself in both directions.
Compare the given function with above equation we get,
[tex]B=10[/tex]
Thus the period of the [tex]\cos (10x)[/tex] is,
[tex]I=\dfrac{2\pi}{|10|}\\I=\dfrac{\pi}{|5|}\\I=\dfrac{\pi}{5}\\[/tex]
Hence the period of the given function is π/5. Thus the option 4 is the correct option.

11. A surveyor is 100 meters from a bridge. The angle of elevation to the top of the bridge is 35º. The
surveyor's instrument is 1.45 meters above the ground. Find the height of the bridge.
Answer:
The height of the bridge is 71.47 m.
Step-by-step explanation:
Since the eye of the surveyor is 1.45m creating the horizontal distance, we must add the 1.45 m to the 70.02 m to determine the total height of the bridge.
70.02 m + 1.45 m = 71.47 m
The height of the bridge is 71.47 m.
At an advertising agency that employs 256 people, 113 employees receive 2 weeks of paid vacation each year. What is the ratio of those who receive 2 weeks of paid vacation to the total number employees?
Answer: 113 : 256
Step-by-step explanation:
There are 113 people to receive a paid vacation every year against a total number of 256 employees.
The ratio is therefore:
113 : 256
113 is a prime number so this is the lowest form this ratio can take.
Simplify the expression:
a (-8a^2 + 2a + 4) +3 (ba^2 - 4)
Answer:
4 a + 2 a^2 - 8 a^3 + 3 a^2 b - 12
Step-by-step explanation:
Simplify the following:
3 (b a^2 - 4) + a (-8 a^2 + 2 a + 4)
Hint: | Distribute a over -8 a^2 + 2 a + 4.
a (-8 a^2 + 2 a + 4) = -8 a^3 + 2 a^2 + 4 a:
-8 a^3 + 2 a^2 + 4 a + 3 (b a^2 - 4)
Hint: | Distribute 3 over a^2 b - 4.
3 (a^2 b - 4) = 3 a^2 b - 12:
Answer: 4 a + 2 a^2 - 8 a^3 + 3 a^2 b - 12

There were 874 tickets sold for a school event. Student tickets were $3 and non-student
tickets were $7. If the total amount of ticket sales was $3,786, how many student
tickets were sold? (Use only the digits 0-9 to enter a number.)
This questions weird
Answer:
583 student tickets
Step-by-step explanation:
This question is likely asking us to set up a system of equations. Let us say that:
x represents the number of student tickets
y represents the number of non-student tickets
We know that there were a total of 874 tickets sold, so:
x + y = 874
We also know that every student ticket was sold for $3 and every non-student ticket was sold for $7. We also know the total sales, so:
3x + 7y = 3786
These are our two equations. We can use substitution to solve for the number of student tickets, x:
x + y = 874
y = 874 - x
3x + 7y = 3786
3x + 7(874 - x) = 3786
3x + 6118 - 7x = 3786
-4x = -2332
x = 583 student tickets

A group of friends were working on a student film that had a budget of $1200. They spent all their budget on costumes and equipment. They used 33% of their budget on equipment. How much money did they spend on costumes?
Answer:
$804
Step-by-step explanation:
33%=0.33----Covert the percentage as a decimal.
0.33*1200=396----Multiply the decimal by the price of budget. This is the cost of equipment.
$1200-$396=$804----Subtract the cost of equipment ($396) by the cost of budget($1200). You get $804!
Hope this helped.

804

Which of the following reveals the minimum value for the equation 2x2 + 12x − 14 = 0? 2(x + 6)2 = 26 2(x + 6)2 = 20 2(x + 3)2 = 32
Answer:
The equation which reveals the minimum value for the equation is 2·x² + 12·x - 14 = 0 is the option;
2·(x + 3)² = 32
Step-by-step explanation:
The given function can be presented as follows;
2·x² + 12·x - 14 = 0
The quadratic equation in standard form is a·(x - h)² + k
Where;
(h, k) is the vertex of the parabola
Given that the coefficient of the x² is positive, the graph is U-shaped and the lowest point is given by the vertex of the graph as follows;
2·x² + 12·x - 14 = 2·x² + 12·x - 14 = 2·(x² + 6·x - 7) = 0
2·(x² + 6·x - 7) = 2·(x² + 6·x + 9 - 7 - 9) = 2·((x + 3)² - 16)
2·((x + 3)² - 16) = 2·(x + 3)² - 32 = 0
∴ 2·x² + 12·x - 14 = 2·(x + 3)² - 32 in vertex form
The minimum value (vertex, (h, k)) for the equation = (-3, -32)
Therefore, the equation which reveals the minimum value for the equation is 2·(x + 3)² = 32
Answer:
2(x + 3)2 = 32

Answer:
JM = 20
Step-by-step explanation:
Find the value of JM
Using similar triangles;
MJ/HN = GJ/HK
GJ+JM/HN = GJ/HK
15+JM/12+16 = 15/12
15+JM/28 = 15/12
Cross multiply
12(15+JM) = 15*28
180+12JM = 420
12JM = 420 - 180
12JM = 240
JM = 240/12
JM = 20
Hence the length of JM is 20

Answer: $6,400
Step-by-step explanation:
First, let's take the given numbers
Starts the account with $1600
Deposits $200 each week after opening it
25 weeks
We can't count the first week because it says "thereafter"
So we need to do 24x200
which is 4,800
Now we must add the original amount deposited and the amount of money added in 25 weeks
1,600+4,800
$6,400
