An arithmetic sequence is represented by the recursive formula A(n) = A(n-1) + 8. If the first term in the sequence is 4, write the explicit formula
Answer:
A(n) = 4 + 8(n-1)
Step-by-step explanation:
A(n) = A(n-1) + 8
A(1) = 4
So A(2) = A(1) + 8 = 4 + 8
A(3) = A(2) + 8 = A(1) + 8 + 8 = 4 + 8 + 8
A(n) = 4 + 8(n-1)
The explicit formula for the arithmetic sequence with the given recursive formula A(n) = A(n-1) + 8 and the first term A(1) = 4 is A(n) = 8n - 4.
Given that the first term (A(1)) is 4, we can observe that each subsequent term is obtained by adding 8 to the previous term.
The general formula for an arithmetic sequence is A(n) = A(1) + (n-1)d, where A(n) represents the nth term, A(1) is the first term, n is the term number, and d is the common difference.
The first term (A(1)) is 4, and the common difference (d) is 8.
Plugging these values into the general formula, we have:
A(n) = 4 + (n-1)×8
A(n) = 4 + 8n - 8
A(n) = 8n - 4

Which representation does NOT show Y as a function of X?
Answer:
D
Step-by-step explanation:
A function is valid if each x input has a different y counterpart
In picture D both 3 and 5 repeat --> (3,2)(2,6) and (5,6)(5,8)
This would create an undefined line that would fail the vertical line test (multiple x values on one y value)
What is the vertex for the equation f (x) = 6(x – 10)2 – 4?
Answer:
(10, -4)Step-by-step explanation:
The vertex form of the equation of quadratic function with vertex (h, k) is:
f(x) = a(x - h)² + q
f(x) = 6(x - 10)² - 4 - given function
so:
a = 6, h = 10, q = -4

A restaurant has 26 tables in its dining room. It takes the waitstaff 10 minutes to clear and set 4 tables. At this rate, how long will it take the waitstaff to clear and set all the tables in the dining room? please hurry
Answer: 65 minutes

6.5 tables per 10 minutes so 6.5 x 10 = 65 min
Answer:
1 hr and 5 minutes
Step-by-step explanation:
here's why... because 4 goes into 26 6 times with a remainder of 2 and there is 5 mins for every 2 tables and 6 times 10 is 60 which equals a hour and that will be a hour and 5 mins

two customers went to a dry cleaners to get clean their shirts and pants. Each shirt cleaning costs the same amount, and each pants cleaning costs the same amount. The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning. The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning. What was the cost, in dollars, of each shirt cleaning?
Answer:
$3.00
Step-by-step explanation:
5x + 3y = 30 - - - - - 1 x 4
3x + 4y =29 - - - - - -2 x 3
--------------------------------------------
20x +12y = 120 - - - - 3
9x + 12y = 87 - - - - - 4
--------------------------------------------
3-4
20x - 9x= 120 - 87
11x = 33
X= 33
11
X = 3
The cost of cleaning each shirt is 3 dollars.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Assuming the cost of cleaning 1 shirt is x and the cost of cleaning 1 pant is y.
The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning.
∴ 5x + 3y = 30...(i)
The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning.
∴ 3x + 4y = 29...(ii)
Now to cancel out 'x' in both equations we multiply eqn(i) by 3 and eqn(ii) by 5.
So, 15x + 9y = 90...(iii) and 15x + 20y = 145...(iv)
Now subtracting (iii) from (iv) we get 11y = 55 ⇒ y = 5 and substituting the value of y in eqn(iv) we get x = 3.
The cost of cleaning each shirt is 3 dollars.

Step-by-step explanation:
Step one:
given
the scale of the map
[tex]2 cm: 8 km.[/tex]
Step two:
so if a scale of 2 cm represents 8 km.
then let xcm be 64km
cross multiply we have

8x= 128
divide both sides by 8

Which types of triangles can have three angles that measure less than 90°?
acute triangle
equilateral triangle
a right triangle
isosceles triangle
Answer:
acute angle
Step-by-step explanation:
acute = angles that are less than 90⁰
The triangles which have three angles that measure less than 90° are:
acute triangle, equilateral triangle
What is acute triangle?"An acute triangle is a triangle with three acute angles that means each angle measures less than 90°."
What is an equilateral triangle?"An equilateral triangle is a triangle where all sides and angles are equal. Each angle of an equilateral triangle measures 60°. "
What is a right triangle?"A right triangle is a triangle where one of the angle measures 90°. "
What is an isosceles triangle?"A triangle that has two sides of equal length is called as an isosceles triangle. Also, two angles that are opposite to equal sides are always equal and measures less than 90°. "
For given question,
As one of the angle of right triangle measures 90°, it is not a required triangle.
Also, for isosceles triangle, although two equal angles measure less than 90°, the third angle can be 90°. So, an isosceles triangle is not a required triangle.
Therefore, the triangles that have three angles that measure less than 90° are:
1) acute triangle
2) equilateral triangle

Molly read 50 out of the 200 pages in her fiction book. Joel is also reading a fiction book, but his book has 280 pages in total. If Joel reads x pages such as the ratio of pages he read is a equivalent to the ratio of pages molly has read, find the value of x.
Answer:
[tex]x = 70[/tex]
Step-by-step explanation:
Given
Molly: 50 out of 200
Joel: x out of 280
Required
Find x
Start by representing the giving parameters as ration
Molly= 50 : 200
Joel = x : 280
From the question, the ratios are equivalent. So,
[tex]50 : 200 = x : 280[/tex]
Convert to fractions
[tex]\frac{50}{200} = \frac{x}{280}[/tex]
Solve for x
[tex]x = \frac{50}{200} * 280[/tex]
[tex]x = \frac{1}{4} * 280[/tex]
[tex]x = \frac{280}{4}[/tex]
