Find a formula for geometric series that begins with 28, 98, 343,...​

Mathematics
1 answer:
otez555 [7]3 years ago
6 0

Answer:

Step-by-step explanation:

In a geometric series, the successive terms differ by a common ratio which is determined by dividing a term by the preceding term.

The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio between successive terms in the sequence.

n represents the number of terms in the sequence.

From the seies shown,

a = 28

r = 98/28 = 343/98 = 3.5

The formula representing the nth term of the given sequence would be expressed as

Tn = 28 × (3.5)^(n - 1)

Write which place to use when comparing the numbers 3,176 & 3,472
bulgar [2K]

Answer:

Step-by-step explanation:

To compare 3,176 and 3,472 using the number line, remember how numbers appear on a number line:

Smaller numbers are to the left, and larger numbers are to the right.

but since both is in the 3,000 just make sure one is on the left and find out where the bigger one goes on the right

Find the equation of the line that is parallel to 3x-4y=6 and passes through the point (-12,10)
horsena [70]
Answer:

y = 3/4x + 19

Explanation:

First we need to write the equation in the form y=mx+c:

3x-4y=6
-4y=-3x+6
y=3/4x-3/2

Because the lines are parallel, we can deduce that the gradients (m) are equal. That means that the gradient of our new equation will also be 3/4.

We will now use the following equation:

y - y1 = m(x - x1)

We will substitute in the new line’s gradient as well as the coordinates we were given:

y - 10 = 3/4(x + 12)

Now we solve this equation into the form y=mx+c:

y - 10 = 3/4x + 9
y = 3/4x + 19

Given the function y-4=5/6(x-2), complete the table of values by entering the missing value.
mylen [45]
The first thing you do is substitute 9 for y in the function, which is,

9 - 4 = 5/6 (x - 2)

Then, you subtract on the left side

5 = 5/6 (x - 2)

Then, you multiply by 6 on both sides

30 = 5 (x - 2)

Then, divide both sides by 5

6 = x - 2

Then, at 2 on both sides to isolate x
& your final answer is

x = 8 (this would be the missing value)
