Find the 29th term in the arithmetic sequence: -13, -6, 1, 8........

Answers

Answer:

183

Step-by-step explanation:

a₁ = -13

common difference = a₂ - a₁

                                 = (-6) - (-13)

                                = -6 + 13

                               d = 7

nth term = a₁ + (n - 1)d

29th term = -13 + 28 * 7

               = -13 + 196

               = 183

I am thinking of a number i multiply by 11 and add 22 i get the same answer if i miltiply by 4 and add 113 whats my number

Answers

Answer: 13

Step-by-step explanation:

Let the number that in thinking of be represented by x.

I multiply by 11 and add 22 will give the same answer as multiplying by 4 and adding 113. This.csn be firmed into an equation as:

(11 × x) + 22 = (4 × x) + 113

11x + 22 = 4x + 113

Collect like terms

11x - 4x = 113 - 22

7x = 91

x = 91/7

x = 13.

The number is 13

Step-by-step explanation:

Given the function representing the number of customers on day x

f(x) = 3ˣ

Part A)

We need to determine the day when there are 243 customers.

so substitute f(x) = 243 in the function

[tex]f\left(x\right)\:=\:3^x[/tex]

Part B)

Solving the equation

[tex]f\left(x\right)\:=\:3^x[/tex]

[tex]243\:=\:3^x[/tex]

as 2⁵ = 243, so

[tex]\:2^5=3^x\:[/tex]

x = 5

The value of x = 5

Part C)

As the value of x = 5

Therefore, on the 5th day, there would be 243 customers.

m = [tex]\frac{13}{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{12}[/tex] = [tex]\frac{m-4}{4}[/tex] ( cross- multiply )

12(m - 4) = 4 ( divide both sides by 12 )

m - 4 = [tex]\frac{4}{12}[/tex] = [tex]\frac{1}{3}[/tex] ( add 4 to both sides )

The mattress can fit through the door.
The door is 78 inches tall and 38 inches wide. If you do the Pythagorean theorem with these numbers you get the hypotenuse of 86.76, which is larger than the width of the mattress.
38^2+78^2=c^2
