In order to find this, we need to count exactly how many times each of them blinks within 60 seconds. Then, we find which numbers are the same.

4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60

6, 12, 18, 24, 30, 36, 42, 48, 54, 60

Now, I will bold the numbers that are the same.

4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60

6, 12, 18, 24, 30, 36, 42, 48, 54, 60

Now, we have our answer.

Answer: The two neon lights will blink on the 12, 24, 36, 48, and 60 second marks.

Hope I helped!

How is this written in an expanded version?

Yuri [45]

Powers distribute over multiplications:

$(ab)^c = a^c\cdot b^c$

So, you have

$(3k^5)^2 = 3^2 \cdot (k^5)^2$

Now, $3^2$ is simply 9.

As for $(k^5)^2$ , we have to use the rule

$(a^b)^c = a^{bc}$

to get

$(k^5)^2=k^{5\cdot 2}=k^{10}$

So, the final answer is

$(3k^5)^2 =9k^{10}$

3.) Write the equation of a quadratic function that is shifted down 4 and horizontally compressed by 1/5

sashaice [31]

Answer:

$5x^2 - 4$

Step-by-step explanation:

For shifted down a function you have to follow the next structured:

$f(x) - c$

In our case is:

$x^2 - 4$

Now for compressed or shrink a graph you have to multiply by a factor in the input something like this:

$f(cx)$

In our case is:

$5x^2$

Maybe you can think, why 5 and not $\frac{1}{5}$ instead?. Well, when you multiply by $\frac{1}{5}$ this dilate or stretch the graft because the output of each value is smaller, example:

$f(x) = x^2\\g(x) = \frac{1}{5} x^2$

Then evaluate for a number, for example 5:

$f(5) = 25\\g(5) = 5$

the output of $g(x)$ is 5 steps a far from the answer of $f(x)$ this in a graph is illustrate as a stretching.

So the opposite happen when you multiply by a integer number, the graph is compressed because the output take the "faster steps".

So combine the two transformation and get $5x^2 - 4$

Convert 15/20 to a percent

Shtirlitz [24]

Hello from MrBillDoesMath!

Answer: 75 %

Discussion:

15/20 = 3/4 = 0.75 = 75 * (1/100) = 75%

Thank you,
