Help me on my review quiz. 10 point btw
arsen [322]

Answer:

96.8 percent

Step-by-step explanation:

You can cut off two zeros from both numbers to compare 1000 to 32.

The difference is 968, and the original is 1000.

So you divide 968 by 1000 to get 0.968 which is equal to 96.8 percent.

Given the exponential equation 4x = 64, what is the logarithmic form of the equation in base 10?
krok68 [10]
4^{x} = 64

By taking <span>logarithmic of base 10

∴ </span><span>log 4^{x} = log 64

∴ x log 4 = log 64

∴ x =  \frac{log \ 64}{log \ 4}

∴ The correct choice is
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>

Find the rule and the graph of the function whose graph can be obtained by performing the translation 3 units left and 2 units d
ahrayia [7]

Answer: Option b.

Step-by-step explanation:

 1. You have the following parent function given in the problem above:

f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)

2. If you take the parent function and make y=f(x+3), then you have:

y=f(x+3)=(x+3)^{3} (The function is shifted 3 units left on the x-axis).

3. Then you if you make y=f(x+3)-2, as following, you obtain:

y=f(x+3)-2=(x+3)^{3}-2  (The function is shifted 2 units down on the y-axis).

4. Therefore, that is how you obtain the final function.

The answer is the graph shown in the option b.
