What is the common difference for this arithmetic sequence?
31, 48, 65, 82, ...

Answers

Answer:

d = 17

Step-by-step explanation:

The given arithmetic sequence is :

31, 48, 65, 82, ...

We need to find the common difference for this sequence.

First term, a₁ = 31

Second term, a₂ = 48

Common difference = a₂-a₁

= 48-31

= 17

So, the common difference for this arithmetic sequence is equal to 17.

what Is the answer to 1/6 + 2/3

Answers

Answer:

5/6

Step-by-step explanation:

When adding fractions, you must ensure the denominator is the same in both fractions.

In this case, the 3 can be multiplied by 2 to equal 6, the other denominator.

When multiplying fractions to create a common denominator, you must multiply the both the numerator and the denominator by the same value, to ensure that the fraction is still equivalent.

2/3 × 2/2 = (2×2)/(3×2) = 4/6

Replace 2/3 with its equivalent 4/6.

Now you will add the numerators together.

1/6 + 4/6 = (1+4)/6 = 5/6

Your final answer is 5/6

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable. In mathematics and the physical sciences, functions are indispensable for formulating physical.

Thus, the table shows that the function is exponential rather than linear.

The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which is 40% of the total miles of their trip. How many total miles is the Jackson’s trip from Boston to New York?

Answers

The answer you are looking for is 210 miles.

To find this answer you must first make 40% into a decimal. To do so, simply divide 40 by 100. This will give you 0.4.

Next, you divide 84 by 0.4. You divide because the percentage of a number is found by multiplying said number by the decimal form of the percent. Since we arent looking for the percentage of a number, but rather the number from which the percentage came, we do the opposite operation.

84 ÷ 0.4 = 210. Thus meaning 210 miles is your answer.

I hope this helps!

The total number of miles that Jackson’s trip from Boston to New York will be 210 miles.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which are 40% of the total miles of their trip.

Let x be the total number of miles. Then the equation is given as,

0.40x = 84

Simplify the equation, then we have

x = 84 / 0.40

x = 210 miles

The total number of miles that Jackson’s trip from Boston to New York will be 210 miles.

If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y

(25m + 22) + (9m) = ?​

Answers

Answer:

Step-by-step explanation:

Simplifying

25m + 22 = 9m

Reorder the terms:

22 + 25m = 9m

Solving

22 + 25m = 9m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-9m' to each side of the equation.

22 + 25m + -9m = 9m + -9m

Combine like terms: 25m + -9m = 16m

22 + 16m = 9m + -9m

Combine like terms: 9m + -9m = 0

22 + 16m = 0

Add '-22' to each side of the equation.

22 + -22 + 16m = 0 + -22

Combine like terms: 22 + -22 = 0

0 + 16m = 0 + -22

16m = 0 + -22

Combine like terms: 0 + -22 = -22

16m = -22

Divide each side by '16'.

m = -1.375

Simplifying

m = -1.375

What is the inequality shown?

Answers

This type of graph is called a segment.

To write the solution set which represents the graph

of a segment, read the segment from left to right.

If you take a look at the segment shown here, we would start with the endpoint on the left which is a -4, our variable x would be in the middle, and we would finish things off with the endpoint on the right, which is 5.

Since we have an open dot at -4, we use a less than sign between the -4 and the x and since we have a closed dot at 5, we use a less tan or equal to sign between the x and the 5.

It's important to understand that when representing a segment by reading it from left to right, you will only use "less than" or "less than or equal to" between the parts, never "greater than" or "greater than or equal to."

So the solution for this graph is read {x: -4 < x ≤ 5}.

For the geometric sequence, find the sum of the specified number of terms.
The first 8 terms of 4, -12, 36, ...
S8=

Answers

Given:

The geometric sequence is

[tex]4, -12, 36,...[/tex]

To find:

The sum of first 8 terms of the given geometric sequence.

Solution:

We have,

[tex]4, -12, 36,...[/tex]

Here, the first term is 4 and the common ratio is

[tex]r=\dfrac{-12}{4}[/tex]

[tex]r=-3[/tex]

The sum of first n terms of a geometric sequence is

[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]

Where, a is the first term and r is the common ratio.

Putting n=8, a=4 and r=-3, we get

[tex]S_8=\dfrac{4((-3)^8-1)}{-3-1}[/tex]

[tex]S_8=\dfrac{4(6561-1)}{-4}[/tex]

[tex]S_8=-6560[/tex]

Therefore, the sum of first 8 terms is -6560.
