Answer:
x = 4
Step-by-step explanation:
110ₓ = 40₅ --------- change all to base ten.
<u>the system called binary</u>
1x²+1x ¹+0x⁰ = 45¹+0*5⁰
x² + x + 0 = 20
x² + x – 20 = 0
solve x using Quadratic equation
-1 ±
x = ------------------------------------
2 * 1
x = -5; x = 4
therefore, x = 4
1. There is no "h" in f(x) = log(x). The question is nonsense.
2. The log function is defined for arguments greater than zero. You're probably expected to select D, though A and B could also be correct.
3. Same deal. The log function is defined for x > -2, but the domain could be restricted to x > 2. You're expected to select FALSE.
4. Same deal. Choose B, though D is also correct.
5. C is the proper choice. (See discussion of the log function, above.)
Answer:
Since the square root of 25 = 5 and the square root of 36 is 6 it is known that the square root of 33 is between 5 and 6.
Step-by-step explanation:
The key to this is to think about perfect squares, specifically the ones closest to 33. These are 25 and 36, which have square roots of 5 and 6 respectively. Because 33 is between these numbers, you know for certain that its square root is between <em>their</em> square roots too.

Answer:
I am writing this in order of least to greatest. [-2] [-1][0][1] [2]
Step-by-step explanation:
We are given with a total money of Jamie equal to five dollars and a total cost of purchase of one dollar and fifteen cents. This purchase is equal to 1.15. The difference is the change that Jamie gets back is 5-1.15 equal to 3.85 dollars in total
