How do you do addition and subtraction in Scientific Notatation?

1 answer:

6 0

Once the numbers have the same base and exponents, we can add or subtract their coefficients. Determine the number by which to increase the smaller exponent by so it is equal to the bigger exponent.

I hope this helps!

Answer:

0.1187

Step-by-step explanation:

A = P (1 + k)^t

where A is the final amount,

P is the initial amount,

k is the monthly growth rate,

and t is the number of months.

70 = 50 (1 + k)^3

1.4 = (1 + k)^3

∛1.4 = 1 + k

k = -1 + ∛1.4

k = 0.1187

Here is a pattern made from sticks: a)How many sticks would be in pattern 6? b) How many sticks would be in pattern number n?

Wittaler [7]

Answer:

a) 26

b) 4n+2

Step-by-step explanation:

From the given figure it is clear that,

Number of sticks in pattern 1 = 6

Number of sticks in pattern 2 = 10

Number of sticks in pattern 3 = 14

Now,

6, 10, 14, ...

It is an AP.

Here, first term = 6

Common difference = 10 - 6 = 4

nth term of an AP is

$a_n=a_1+(n-1)d$

where, $a_1$ is first term and d is common difference.

So, nth term of given AP is

$a_n=6+(n-1)4$

$a_n=6+4n-4$

$a_n=4n+2$

Now, substitute n=6 in the above equation to find the number of sticks in pattern 6.

$a_n=4(6)+2=24+2=26$

Therefore, the number of sticks in pattern 6 is 26.

Since $a_n=4n+2$ , therefore, the number of sticks in pattern n is 4n+2.
