Or 7n-4 (that’s an example) if it’s correct I’ll mark u brainiest.

Can Someone Help Me Find Out Whats The Nth Formula Equation An Example Is Where It Should Look Like 65^n-1Or

Answers

Answer 1

Part (a)

This sequence is arithmetic because we are adding 4 to each term to get the next term. Nice work on getting the correct answer here.

To get the nth term of an arithmetic sequence, we'll use the formula below

an = a + d(n-1)

In this case, a = 14 is the first term and d = 4 is the common difference

So we have these steps

an = a + d(n-1)

an = 14 + 4(n-1)

an = 14 + 4n - 4

an = 4n + 10

Answer: 4n + 10

============================================

Part (b)

This sequence is geometric since we multiply each term by 4

The common ratio is r = 4 and the start term is a = 2.

So the nth term is....

an = a*(r)^(n-1)

an = 2*(4)^(n-1)

Answer: 2*(4)^(n-1)

Determine if the side lengths given form a triangle. Justify your response. 6.4 mm, 12.9 mm, 14.2 mm

Answers

Answer:

Step-by-step explanation: Yes I think since if you add 12.4 and 6.4 your answer is more then 14.2 so yes it is possible

Answer:

Yes, it does form a triangle

Step-by-step explanation:

According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that the given side lengths DO form a triangle. 6.4+12.9=19.3 which is more than 14.2.

PLS HELP The width of Ben's rectangular family
room is 3 feet less than the length.
The perimeter is 70 feet. What is the
length of the family room?

Answers

Answer:

19 feet

Step-by-step explanation:

The perimeter is calculated by multiplying the sum of length and width by 2

width is 3 less than length so if we call the width x the length would be x + 3

2×(x + x + 3) = 4x + 6 and

4x + 6 = 70 subtract 6 from both sides

4x = 64 divide both sides by 4

x = 16

The length is x + 3 so the answer is 19 feet

What is the standard form equation for a 1/2 line that passes though (-3,-3) and (4,2)

Answers

Answer:

y= 5/7x -2.7

Step-by-step explanation:

Y= mx + c                             (-3,-3)   (4,2)

                                           x1  , y1     x2, y2

to find m (gradient)

y^2 - y^1 / x^2 - x^1

2-(-3) / 4 - (-3)

5/7                               m = 5/7

take (4,2)  and gradient and substitute

2=5/7(4) + c

2=4.7+ c

2-4.7 = c

-2.7 = c

now we have c and m so just put it in the equation

y= 5/7x -2.7
