Answer:
[tex]b=\frac{1}{6}[/tex]
Step-by-step explanation:
In [tex]f(x)=a\cos(b(x-c))+d[/tex], [tex]b[/tex] represents a constant related to the period of the function. Here's how it's related:
[tex]b=\frac{2\pi}{T}[/tex], where [tex]T[/tex] is the period of the function.
We're given [tex]T=12\pi[/tex], so solving for [tex]b[/tex]:
[tex]b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}[/tex]

Find the Area of the shape
(Area of Composite Shapes)
Answer:
130 inches
Step-by-step explanation:
Area = Length · Width
Solve for the Right Triangle
6 · 11 = 66 inches
Area = Length · Width
Solve for the square
Since the width isn't fully given, we must add 5 + 3 = 8 inches
5 · 8 = 40 inches
Area = Length · Width
Solve for the Rectangle
8 · 3 = 24 inches
Now add the results: 66 + 40 + 24 = 130 in^2

Step-by-step explanation:
A parachutist's speed during a free fall reaches 50 meters per second. What is this speed in feet per second? At this speed, how many feet will the parachutist
fall during 5 seconds of free fall? In your computations, assume that 1 meter is equal to 3.3 feet. Do not round your answers.
Answer:
speed of parachutists will be 50×3.3= 165 feet per second.
Step-by-step explanation:
hence distance traveled = speed × time taken
=165×5
=825 feet

D) Sum of the two adjacent angles is 140°. If the second angle is 7 less than six times the first angle, find the two angles. (2 Marks)
Answer:
FIRST ANGLE = 21 degree
SECOND ANGLE = 119 degree
Step-by-step explanation:
140 = 6x - 7 + x
140 = 7x - 7
combine like terms
140 + 7 = 7x
147 = 7x
x = 21
second angle = 6(21) - 7 = 119
determine the equation of the circle graphed below .
( help please )
Answer:
(x + 5)² + (y - 4)² = 17
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 5, 4 ) , then
(x - (- 5) )² + (y - 4)² = r² , that is
(x + 5)² + (y - 4)² = r²
r is the distance from the centre to a point on the circle
Calculate r using the distance formula
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 5, 4) and (x₂, y₂ ) = (- 1, 5)
r = [tex]\sqrt{(-1+5)^2+(5-4)^2}[/tex]
= [tex]\sqrt{4^2+1^2}[/tex]
= [tex]\sqrt{16+1}[/tex]
= [tex]\sqrt{17}[/tex] ⇒ r² = ([tex]\sqrt{17}[/tex] )² = 17
Then
(x + 5)² + (y - 4)² = 17 ← equation of circle
Answer:
x² + y² + 10x - 8y + 24 = 0
Step-by-step explanation:
equation of a circle :-
equation of a circle :-(x - h)² + (y - k)² = r²
(h, k) is the center of the circle R is the radius of the circlefor this circle :-
h = -5k = 4R = ?finding radius of the circle
we've been given a point ( -1, 5) that lies on the circle and hence should satisfy the equation of the circle
putting x = -1 and y = 5
=> (-1 - (-5))² + (5 - 4)² = r²
=> (-1 + 5)² + 1² = r²
=> 4² + 1 = r²
=> 17 = r²
[tex] = > r = \sqrt{17} [/tex]
the radius if the circle is √17 units
__________________________________
finding the equation of the circle
=> (x + 5)² + (y - 4)² = (√17)²
=> x² + 25 + 10x + y² + 16 - 8y = 17
as for any two variables a and b, (a + b)² = a² + b² + 2ab=> x² + y² + 10x - 8y + 24 = 0

Need the question answered it's urgent?
Answer:
x =5
Step-by-step explanation:
2x+x-5 =x+5
Combine like terms
3x - 5 = x+5
Subtract x from each side
3x-x-5 = x+5-x
2x -5 =5
Add 5 to each side
2x-5+5 = 5+5
2x = 10
Divide by 2
2x/2 = 10/2
x =5
Answer:
x = 5
Step-by-step explanation:
2x + x - 5 = x + 5
combine like term
3 x - 5 = x + 5
subtract x from 3x
3x - x - 5 = 5
2x - 5 = 5
add 5 to 5 , we get
2x = 5 + 5
2x = 10
divide ➗ 10 by 2
x = 10/ 2
x = 5

74 + -28 =[find the difference and put the sign of big number]
Answer:
It should be 74+(-28) as 2 signs can bit be put together.
74+(-28)
=74-28 (sign only changes when there is (minus) before it
=48
We are not putting a minius (-) as 74 is digger that 28 and it has plus (+) before it.

Using the tables as experimental data, determine whether it is more likely for a new food establishment to succeed and earn up to $25,000, or whether it is more likely for a new financial establishment to succeed and earn profits in either the $25,000-50,000 range or the $50,000-75,000 range, and how much more likely the one situation is than the other. Express all probabilities as percentages to two decimal places, and express differences by number of percentage points (for example, 23% is 5 percentage points greater than 18%). a. The situation involving the financial establishment has a probability 11.14 percentage points higher than the situation involving the food establishment. b. The situation involving the financial establishment has a probability 12.03 percentage points higher than the situation involving the food establishment. c. The situation involving the food establishment has a probability 2.08 percentage points higher than the situation involving the financial establishment. d. The situation involving the food establishment has a probability 2.36 percentage points higher than the situation involving the financial establishment.
The situation involving the food establishment has a probability of "2.08 % " points higher than the situation involving the financial establishment
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The question is incomplete, as the required table which is not given.
we have the following parameters:
The probability that the establishment earns up to $25k = 10.59%
The probability that the establishment earns between $25k - $50k or $50k - $75k = 8.56%
Using the above values, the difference in the probabilities are;
d = 10.59% - 8.56
d = 2.03%
Hence, the true statement about the probability is option (d)

The number of children studying in different schools of kanpur is 6,45,55,587 . If the number of boys is 4,55,25,400, find the number of girls.
Answer:
19030187 girls
Step-by-step explanation:
Total number of children = 6,45,55,587
number of boys =4,55,25,400
Number of girls= (Total number of children ) - (number of boys )
= (6,45,55,587)-(4,55,25,400)
= 19030187 girls
The number of girls. Is 19030187

1. -9
2. -1
3. 8
4. 15
The value of a₄ is -9
What is recursively defined sequence?Recursively defined sequence is the sequence where every term is calculated by the use of the one or more previous term given.
In this given problem
a₁ = 5
given relation between term is [tex]a_{n+1}[/tex] = 2aₙ -7
using this relation
take n=1
a₂ = 2a₁-7 =(2*5)-7=3
then by taking n=2
a₃ = 2a₂-7 =(2*3)-7=-1
then taking n=3
a₄= 2a₃-7 =(2*(-1))-7= -9
so the final answer will be a₄ = -9

HELP WITH THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
B., E.
Step-by-step explanation:
what was the difficulty ? this is just to understand the movement of a thrown rock.
what happens, when you throw a rock through the air ? it will first move up a little bit, reaches a maximum height, and then drops down again.
that is what the graphic shows.
so, can A. be correct ? no. as we move from 0 seconds to the right (time passes) the height of the rock increases first (before decreasing again later on).
can C. be correct ? no, it would mean that the function would look the same on both sides of the x-axis. this is clearly impossible.
can D. be correct ? no, nowhere in the graph is the height (= the functional value, the y to the x) negative.
can F. be correct ? no, we clearly see the maximum height at 1.5 seconds. at 3 seconds the height is actually at its minimum.
help quickly pls area of a triangle: sine formula
Answer:
If you were to use the sine formula you would have to use the cosine formula to get one of the opposite sides and then use the sine formula.
For the area why not use 1/2 * 20 to get the base.
Then the height would be 24 * sin 63 = 21.38
That would give an area of 213.8
