Expand log 3x^4

1 answer:

5 0

In this case it's, log(u)^n = nlog(u)

so the answers are either 4 log (3x) or it could also be 4[log3 + log x]
There is no need for the solution to be shown because this is a simple rule of properties of logarithms

Where would (0.5,2) be potted ? Please answer this !!

NISA [10]

(0.5,2)

0.5 is x value

2 is y value

---------------

x value is on dashed line (0.5)

y value is on more separated line going up and down. (2)

To plot 0.5, you can put it as an equation. 0.5= 1/2. So to plot it, 0.5 is half of 1. So plot it as in between the 1 and 0.

To plot 2 go up to the two on the y axis and then go over 0.5 and plot a point.

That is you're plotted point for (0.5,2)

Hope it helps!

Answer:

2/5 hour is closest to 0 1/2 hours, 5/8 hour is closest to 1/2 hour. Therefore, the best estimate for the total time Maria spent with her sister is close to 1 hour

Step-by-step explanation:

We can represent the time Maria spends playing the game as 0.4, since 2/5 as a fraction is 0.4. This is closer to 1/2, which is 0.5 then it is to 0, because 4 is closer to 5 then 0. Then, we can represent the time Maria reads the book as 0.625, which is closer to 1/2 then it is to 1. Now we can add the estimated times. $1/2+1/2=1$ hour

Answer: 1.58 hours

Step-by-step explanation:

$5400=1800(2)^t\\\\3=2^t\\\\ln\ 3=ln\ 2^t\\\\ln\ 3=t\cdot ln\ 2\\\\\dfrac{ln\ 3}{ln\ 2}=t\\\\1.58=t$
