You have to go past the decimal point in since the first number in the tenths place is a zero you can't really round here so you go to the hundreds place and not so three you round down because 3 is closer to 0 then it is 10 so it would be 1. 4

How many times larger is 4x10^7 than 5x10^5

irina1246 [14]

Answer:

8 times larger

Step-by-step explanation:

4 · $10^{7}$ = 4 · 10 · 10 · 10 · 10 · 10 · 10 · 10

4 · 100 · 100 · 100 · 10

400 · 10000 · 10

= 40000000

5 · $10^{5}$ = 5 · 10 · 10 · 10 · 10 · 10

50 · 100 · 100 · 10

5000 · 1000

= 5000000

40000000 ÷ 5000000 = 8

What are the solutions of 3(2m − 1) ≤ 6m − 2?

kaheart [24]

Hello from MrBillDoesMath!

Answer:

The solution set is the set all all real number m

Discussion:

3(2m-1) <= 6m-2 =>

3*2m - 3*1 <= 6m-2 =>

6m - 3 <.= 6m-2 => (Subtract 6m from both sides)

0-3 <= -2 =>

-3 < = -2

As -3 <=-2 is always true the solution set is the set all all real number m

Define the function

miss Akunina [59]

Given that

$g(x) = x^3 + x$

the inverse $g^{-1}(x)$ is such that

$g\left(g^{-1}(x)\right) = g^{-1}(x)^3 + g^{-1}(x) = x$

$g\left(f(x)\right) = f(x)^3 + f(x) = x$

Differentiating both sides using the chain rule gives

$3f(x)^2f'(x) + f'(x) = 1 \\\\ f'(x) \left(3f(x)^2+1\right) = 1 \\\\ f'(x) = \dfrac1{3f(x)^2+1}$

Then the derivative of f at 2 is

$f'(2) = \dfrac1{3f(2)^2+1} = \boxed{\dfrac14}$
