Let {an} be a sequence that satisfies the recurrence relation an = an-1 + 3 for n = 1, 2, 3, ... , and suppose that a0 = 2. What are a1, a2, and a3? Show your solution.
Given:
[tex]a_n=a_{n-1}+3[/tex]
[tex]a_0=2[/tex]
To find:
The values [tex]a_1,a_2,a_3[/tex].
Solution:
We have,
[tex]a_n=a_{n-1}+3[/tex]
For [tex]n=1[/tex],
[tex]a_1=a_{1-1}+3[/tex]
[tex]a_1=a_{0}+3[/tex]
[tex]a_1=2+3[/tex]
[tex]a_1=5[/tex]
For [tex]n=2[/tex],
[tex]a_2=a_{2-1}+3[/tex]
[tex]a_2=a_{1}+3[/tex]
[tex]a_2=5+3[/tex]
[tex]a_2=8[/tex]
For [tex]n=3[/tex],
[tex]a_3=a_{3-1}+3[/tex]
[tex]a_3=a_{2}+3[/tex]
[tex]a_3=8+3[/tex]
[tex]a_3=11[/tex]
Therefore, [tex]a_1=5,a_2=8,a_3=11[/tex].
The value of [tex]\rm a_1=5[/tex], [tex]\rm a_2=8[/tex], and [tex]\rm a_3=11[/tex] and this can be determined by using the arithmetic operations and the given data.
Given :
Let {an} be a sequence that satisfies the recurrence relation [tex]\rm a_n=a_{n-1}+3[/tex] for n = 1, 2, 3,... and suppose that [tex]\rm a_0=2[/tex].
According to the given data, the recurrence relation is given below:
[tex]\rm a_n=a_{n-1}+3[/tex] --- (1)
Now, substitute the value of (n = 1) in the above expression.

Answer:
The first one is D and the second one is B
Step-by-step explanation:
The first is D because the volume of a cylinder is v = π (pi) times the radius squared times the height of the cylinder.
so (π)(16^2)(7) =5629.73 ft^3
Then 1 ft^3 is = 7.5 gallons of water, so you multiple 5629.73 by 7.5 and round. Which gets you 42223

A copper plate is in the shape of an isosceles triangle with a base of 34 inches. The perimeter of the plate is 110 inches. How long is each of the equal sides of the plate
Answer:
An isosceles triangle has 2 equal sides. If the perimeter is 110 inches, and your base is 34 inches, subtract the base from the total perimeter. 110-34= 76. If 2 sides have to be equal, the total length of the 2 sides is 76 inches, divide the 2 lengths by 2 to get the measure of each side individually. 76÷2=38.
Hence, your answer is each of the equal sides of the plate equals 38 inches.

number of hours sold = fraction of houses sold this year x number of houses built last year
4/7 x 210 = 120 houses

Answer:
B) 544in
Step-by-step explanation:
The area for the front triangle is 48in. So the back triangle is also 48in.
The area for the side rectangles are each 140in.
And the area for the bottom rectangle is 168in.
Add all the values together: 48+48+140+140+168=544

Find the coordinates of point P witch cuts line segment AB into two parts with a ratio of 3:8
point a : (-15,18) POint B (7,7)
Answer:
Step-by-step explanation:
So we'll take the ratio of 3:8 to mean 3 to 8 , which is 11 total parts.
since we know that part, and we can see that the x coordinate goes from -15 to 7, which is a total of 22 and that y goes from 18 to 7, which is a total of 11 then we know that we can just break up each into their 3:8 ratios
3:8=11 for the y component
6:16=22 for the x component
so subtract 3 from the B point for the y or add 3 to the A point , either works here, Let's go from B so y = 10 (7+3) and x = 1 (7-6)
So a point at (1,10) will be on the line and at a ratio of 3:8 :)

You and your friend are selling magazine subscriptions. You sell 8 fewer magazine subscriptions than your friend. Together you sell 42 magazine subscriptions. a. Write a system of linear equations that represent the situation.
b. How many magazine subscriptions did you sell?
c. How many magazine subscriptions did your friend sell.
Answer:
b. you sold 17
c. your friend sold 25
Step-by-step explanation:
you=y your friend=x
y=x-8
42=x +y
42=x+(x-8)
42=x+x-8
42=2x-8
50=2x
25=x
Use x to solve for y...
y=25-8

What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here: The linear equation is y=2x-4
Now the equation y=2x+9
equating both linear equations are
2x-4=2x+9
-4=9 which is not possible
Thus the incorrect equation that gives no solution is y=2x+9

Plz give the answer for 8th and 9th question
Answer:
8. 8/9 is not the multiplicative inverse of –1⅛
9. 0.3 is the multiplicative inverse of 3⅓
Step-by-step explanation:
To answer the above questions, we must understand the meaning of multiplicative inverse. This is illustrated below:
Let y be the number.
The multiplicative inverse of y denoted by y¯¹ (or 1/y) when multiplied with y will give an identity of 1 i.e
y × y¯¹ = 1
Or
y × 1/y = 1
Now, let us answer the questions given above by calculating the multiplicative inverse.
8. The number (y) = –1⅛ = –9/8
Multiplicative inverse (y¯¹) =?
y × y¯¹ = 1
–9/8 × y¯¹ = 1
Divide both side by –9/8
y¯¹ = 1 ÷ –9/8
y¯¹ = 1 × –8/9
y¯¹ = –8/9
Thus, 8/9 is not the multiplicative inverse of –1⅛
9. The number (y) = 3⅓ = 10/3
Multiplicative inverse (y¯¹) =?
y × y¯¹ = 1
10/3 × y¯¹ = 1
Divide both side by 10/3
y¯¹ = 1 ÷ 10/3
y¯¹ = 1 × 3/10
y¯¹ = 3/10
y¯¹ = 0.3
Thus, 0.3 is the multiplicative inverse of 3⅓.
