PLEASE HELP!!

madam [21]

Answer:

k=2/3

Step-by-step explanation:

Step 1:

Step 1 in solving the exponential equations is re-writing the base same as other side of the equation

so,

$25^{3k}=625\\=> 25^{3k}=25^2$

Step 2:

Second step is equating the exponents

The rule used is:

$If\ B^m=B^n\ then\ m=n$

So in this case

$3k=2\\k = \frac{2}{3}$

So the solution is:

k=2/3 ..

Need help on this! Please someone help!!!

This can be easily solved, especially with a calculator.
With the calculator, you can find that $\sqrt{42}$ is about 6.4807.
Multiply that by 2, you get about 13 inches.

If you can't use a calculator, then you can just estimate. Since we know that $\sqrt{36}$ is 6 and $\sqrt{49}$ is 7, $\sqrt{42}$ is in between them, so you can just say somewhere around 6.5.

Multiply 2 * 6.5 and you get 13 inches.

4x+8<-16

x<-6

x_>-1

(it's more and equal .so the circle has to be shaded and move to the right of -1)

How much would it cost to buy 3 $13 battery packs and 3 $22 copper wires

Makovka662 [10]

It would cost $105 because if you do 13+13+13= 39
22+22+22= 66
66+39= 105.
