What is the ninth term of the arithmetic sequence defined by the rule below?A(n)= -14+(n-1)(2)

Answers

Answer 1

Answer: We need to just plug in n = 9 into the rule to find out the 9th term.

A(9)= -14+(9-1)(2)

Subtract 9-1
A(9) = -14+(8)(2)

Multiply 8*2
A(9) = -14+16

Add -14+16, which is the same as 16-14
A(9) = 2

The 9th term is 2.

Answer 2

Answer: A(9) = -14 + (9-1)(2)
A(9) = -14 + (8)(2)
A(9) = -14 + 16
A(9) = 16 - 14

A(9) = 2

If an equation does not need the distributive property, what should you look for next?

Answers

Answer:

Proceed the next step, then. Whether it is sum/subtract the addends, whether it is subtract. Then isolate the variable, aiming to find out the quantity of x.

Step-by-step explanation:

If an equation whose product does not need the distributive property, then the factors have already been distributed. And

Visualizing it

Suppose the following equation:

$3(x+2)=4$

Now let's focus the following step, that point of the question, when the equation does not need the distibutive property:

3x +6=4

3x+6 -6=4-6

3x=-2

3x/3=-2/3

x=-2/3

S={-2/3}

I would say to look for any like terms to combine, looking at the range of different variables and terms on both sides of the equation.

How do I solve this??

Answers

Answer:

r = -1/2

Step-by-step explanation:

3(5 + 4r) = -18r

15 +12r = -18r by distributive property

15 = -12r - 18r

15 = -30r

r = - 1/2r

Answer: Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form:

r=−411

Decimal Form:

r=−0.¯¯¯¯36

Steve has a steel barrel with a diameter of 4 feet that can be filled to a depth of 4.3 feet with oil. What is the volume of the barrel?Use = 3.14

A.
54.008 cubic feet

B.
51.6 cubic feet

C.
78.128 cubic feet

D.
17.708 cubic feet

Answers

Answer:

Option A. 54.008 cubic feet

Step-by-step explanation:

we know that

The volume of the barrel is equal to

$V=\pi r^(2)h$ ----> volume of the cylinder

we have

$r=4/2=2\ ft$ ----> the radius is half the diameter

$h=4.3\ ft$ ---> is the depth

$\pi =3.14$

substitute

$V=(3.14)(2)^(2)(4.3)$

$V=54.008\ ft^(3)$
