Answer:
[tex]a_{n}[/tex] = 10n - 5
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 15 - 5 = 25 - 15 = 10
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 10 , then
[tex]a_{n}[/tex] = 5 + 10(n - 1) = 5 + 10n - 10 = 10n - 5

a certain state the license plate has two digits, then two letters, and then two digits. How many different license plates are possible if letters and digits cannot be repeated?
Answers
Step-by-step explanation:
Choosing 4 digits out of 10 = 10C4 = 210.
Arranging the 4 digits in 4 places = 4!
Total number of ways to arrange digits
= 210 * 4! = 5040.
Choosing 2 letters out of 26 = 26C2 = 325
Arranging the 2 letters in 2 places = 2!
Total number of ways to arrange letters
= 325 * 2! = 650.
Total number of possible license plates
= 5040 * 650 = 3,276,000.
Answer:
3,276,000
Step-by-step explanation:
10 x 9 x 26 x 25 x 8 x 7 = 3,276,000
the numbers 10, 9, 8, 7 are the spaces available for a non-duplicated digit
the numbers 26 and 25 are for two non-duplicated letters

The scatterplot for number of enrollments, N, in a sports club, t years after the
year 2006. The equation of the line of the best fit is N = 62t + 35. Find the residual
for the number of enrollments in year 2020 if the actual enrollment is 885
students.
Answers
Answer:
13.7 years
Step-by-step explanation:
The equation of the line of the best fit is N = 62t + 35
where
N is the number of enrollments
t is years after the year 2006
If the actual enrollment is 885 students. Put N = 885 in the given equation.
885 = 62t + 35
or
885 -35 = 62t
850 = 62t
t = 13.7 years
So, the required answer is 13.7 years.

Solution
x is an angle hence we are gonna use the formula Sin
Sin 0 = opp/hyp
0 represents theta.
Sin 0 = opp/hyp
Sin 0 = 27/33
Put 27/33 in decimal form
= 0.8181
Transpose to make 0 the subject
Sin 0 = 0.8181
0 = Sin-1 0.8181
When adding Sin from one side to another it becomes Sin inverse.
0 = Sin-1 08181
Now we find the answer
0 = Sin-1 0.8181
= 54.89 degrees
Therefore x is equal to 54.9 to the nearest tenth.

The number of sunflowers (s) in the garden is one more
than twice the number of roses (r):
is it inequality it not
what's its inequality model—×??
Answers
Answer:
s = 2r + 1
Step-by-step explanation:
Number of sunflower (s) is 1 more than twice the number of roses (r)
Mathematically ;
Number of sunflower = 1 + 2 * number of roses
Sunflower = s ; roses = r
s = 2r + 1
We want to study the relation between the number of sunflowers and roses, we will see that it is an equation and the equation is:
s = 2*r + 1
So we know that the number of sunflowers is one more than twice the number of roses, notice that it represents an equation (so it is not an inequality)
And the equation can be written as:
s = 2*r + 1
The number of sunflowers is 2 times the number of roses, plus 1.

Patrick is riding his bike on a rectangular path around his city.
There is a rest area at each of the path's four corners.
• The city map shows the corners marked with coordinates of (2, 2), (1, 2), (1, -2), and (-2,-2).
Each unit represents 2.5 miles.
What is the perimeter of the path, in miles?
Answers
With the given coordinates it doesn't form a rectangle the correct set of the coordinates should be (2, 2), (1, 2), (1, -2), and (2,-2).
Answer:
The perimeter of the given rectangle that is formed by the given coordinates is 30miles.
Step-by-step explanation:
We are given the Rectangular coordinates such as
(2,2) , (1,2) ,(1,-2) (2,-2)
we will mark these point on the cartesian planes to understand the rectangle
We can apply the distance formula or we can just look on the cartesian plane to simply get the distance between two points
we get
[(2,2) ,(1,2) ] and [(1,-2) ,(2,-2) ] are two units apart each pair as they are parallel so our width is
W = 2 units
similarly
we now need the length
(1,2) and (1,-2) are four units apart
so our length will be four units
L= 4 units
we need the perimeter
Perimeter of the rectangle = 2( L+W)
= 2( 2 + 4)
= 2* 6 = 12units
Now we are given that 1 unit is equal to 2.5 miles so 12 units will be
= 12* 2.5 = 30 miles
Therefore The perimeter of the given rectangle that is formed by the given coordinates is 30miles.

3x²(x² - 5x + 2) + 2x(x² - 5x + 2) + 3(x² - 5x + 2) ← distribute parenthesis
= 3[tex]x^{4}[/tex] - 15x³ + 6x² + 2x³ - 10x² + 4x + 3x² - 15x + 6 ← collect like terms
