26+6b greater than or equal to 2(3b+4)?

1 answer:

4 0

Greater than because no matter what variable b is equal to your equation will always look like this:

26+6b = 6b+4 ; which is false.
thus it is greater than

Is 7 to the 8th power times 7 equivalent to 7 to the the third power times 7 to third power equivalent?

Akimi4 [234]

Answer:

They are not equivalent.

Step-by-step explanation:

Before we solve the question, we need to know that from the laws of indices:

A^x x A^y = A^(x+y).

7 to the power of 8th power means 7^8

7^8 times 7 means 7^8 x 7. From the laws of indices we have 7^8 x 7 = 7^9.

7 to the power of 3rd power means 7^3

7^3 times 7 to the power of 3rd power means 7^3 x 7^3. From the laws of indices we have 7^3 x 7^3 = 7^6.

Obviously, 7^9 ≠ 7^3 therefore, they are not equivalent.

A city was founded at the beginning of 1990 with a population of 55,000, and since then, the growth in its population has been e

andrew-mc [135]

You can solve this analytically to get
.. 55000*(1 +x/100)^10 = 108193
.. (1 +x/100)^10 = 108193/55000
.. 1 +x/100 = (108193/55000)^(1/10)
.. x = 100*((108193/55000)^(1/10) -1) ≈ 7.00

but I find it just as fast to have a graphing calculator do it.

The city's population is increasing 7% per year.
