Answer:
f(n) = 18 + 4n
Step-by-step explanation:
= 22 + 4(n-1)
= 22 + 4n - 4
= 18 + 4n
The formula used for the arithematic sequence will be f(n) = 18 + 4n
What is an arithmetic sequence?An arithmetic sequence is a series of numbers in which the difference between the next term to its previous term remains constant for the whole series. This difference is called a common difference.
Given that:-
A theater has 18 rows of seats. There are 22 seats in the first row, 26 seats in the second row, 30 seats in the third row, and so on
The formula will be given as follows:-
f(n)= 22 + 4(n-1)
f(n)= 22 + 4n - 4
f(n)= 18 + 4n
Therefore the formula used for the arithmetic sequence will be f(n) = 18 + 4n

Answer:
-9<x≤2
Step-by-step explanation:
The domain is the x values
If we look at the line, we see a closed circle when x=2, so x is less than or equal to 2
The other circle is open and is at -9, so x is greater than -9
-9<x≤2

The diameter of a circle is 10 m. Find its area to the nearest tenth.
Answer:
78.54 m^2
Step-by-step explanation:
The computation of the area of the circle is shown below:
As we know that
Area of the circle = πr^2
Also
Diameter = 2r
10 = 2r
r = 5
So, the area of the circle is
= 3.14 × 5^2
= 78.54 m^2

An airplane is observed to be approaching the air point. It is at a distance of 12 km from the point of observation and makes an
angle of elevation of 50 degree. Find the height above the ground.
Answer:
The height is 14.3 km
Step-by-step explanation:
Given
[tex]distance= 12km[/tex]
[tex]\theta= 50[/tex] --- angle of elevation
Required
Determine the height above the ground
The question is illustrated using the attached image.
To calculate the required height, we make use of:
[tex]tan(\theta) = \frac{AB}{BC}[/tex]
Where AB represents the height and BC, the distance.
So:
[tex]tan(50) = \frac{AB}{12}[/tex]
Make AB the subject
[tex]AB = 12 * tan(50)[/tex]
[tex]AB = 12 * 1.1918[/tex]
[tex]AB = 14.3016[/tex]
[tex]AB = 14.3km[/tex] --- approximated
The height of the airplane above the ground is 9.19 km.
Trigonometric ratioTrigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the airplane above the ground. Hence:
sin(50) = h / 12
h = 9.19 km
The height of the airplane above the ground is 9.19 km.

Write an equation of the parabola shown.
Answer:
y = 0.1(x + 5)² + 1.5
Step-by-step explanation:
Equation of a parabola having vertex at (h, k) is given by,
y = a(x - h)² + k
From the given graph, vertex of the parabola is (-5, 1.5)
Therefore, equation of the parabola will be,
y = a(x + 5)² + 1.5
Since, this parabola passes through a point (0, 4)
4 = a(0 + 5)² + 1.5
4 = 25a + 1.5
25a = 2.5
a = 0.1
By substituting the value of 'a' in the equation of the parabola,
y = 0.1(x + 5)² + 1.5
the actual weights of bags of pet food are normally distributed about the mean of 50.0 lb with a standard deviation of 0.2 lb.
1. About what percentage of bags of pet food weigh between 49.8 lb and 50.2 lb?
2. About what percentage of bags weigh less than 49.8 lb?
3. In a group of 250 bags, what percentage of bags would you expect to weigh more than 50.4?
9514 1404 393
Answer:
68%16%2.5%Step-by-step explanation:
1. The empirical rule tells you 68% of the distribution is within 1 standard deviation of the mean. The mean is 50 and the standard deviation is 0.2, so this means 68% of the bags weigh between 49.8 and 50.2 lb.
__
2. The other 32% is evenly split above and below the central part of the distribution. That is, about 16% of the bags will weigh less than 49.8 lb.
__
3. The percentage is independent of the size of the group. The empirical rule tells you 95% lie within 2 standard deviations of the mean. The other 5% will be evenly split between those weighing more than 50.4 and those weighing less than 49.6 lb. About 2.5% of the bags will weigh more than 50.4 lb.
_____
Additional comment
It is useful to remember the empirical rule numbers, 68%, 95%, 99.7% for the portion of the distribution between ±1, 2, 3 standard deviations of the mean. They are useful for answering questions like this one. (They are only approximations, so if more accuracy is needed, a table or app should be used to find the accurate value.)

Dan enlarged the size of a rectangle to a height of 22.4 in. What is the new width of the rectangle if it was originally 5.6 in tall and 1.4 in wide
Answer:
The new width is 5.6 in
Step-by-step explanation:
Given
New
[tex]H_2 = 22.4[/tex]
Old
[tex]H_1 = 5.6[/tex]
[tex]W_1 = 1.4[/tex]
Required
The new width
This is calculated using the following equivalent ratio
[tex]H_2 : W_2 = H_1 : W_1[/tex]
[tex]22.4 : W_2 = 5.6 : 1.4[/tex]
Express as fraction
[tex]W_2/22.4 = 1.4/5.6[/tex]
Multiply both sides by 22.4
[tex]W_2= 1.4/5.6 * 22.4[/tex]
[tex]W_2= 5.6[/tex]
