12p + 15 - 13 - 12p
12p - 12p is cancelled
15 - 13 equals 2
Therefore the answer is 2
Answer:
The three zeros of the original function f(x) are {-1/2, -3, -5}.
Step-by-step explanation:
"Synthetic division" is the perfect tool for approaching this problem. Long div. would also "work."
Use -5 as the first divisor in synthetic division:
------------------------
-5 2 17 38 15
-10 -35 -15
--------------------------
2 7 3 0
Note that there's no remainder here. That tells us that -5 is indeed a zero of the given function. We can apply synthetic div. again to the remaining three coefficients, as follows:
-------------
-3 2 7 3
-6 -3
-----------------
2 1 0
Note that the '3' in 2 7 3 tells me that -3, 3, -1 or 1 may be an additional zero. As luck would have it, using -3 as a divisor (see above) results in no remainder, confirming that -3 is the second zero of the original function.
That leaves the coefficients 2 1. This corresponds to 2x + 1 = 0, which is easily solved for x:
If 2x + 1 = 0, then 2x = -1, and x = -1/2.
Thus, the three zeros of the original function f(x) are {-1/2, -3, -5}.
The answer is Demographic data
The researcher includes the following material in a research report: The seven males varied in age from 32 to 45 (M = 38), had a high school education (two had high school diplomas, one had an associate degree, three had an undergraduate degree, and one had a master's degree), and had yearly incomes ranging from $20,000 to $100,000 (M = $52,000). Demographic data refers to information on the characteristics of the individuals being investigated.
What is Demographic data?
- Demographic analysis is the examination of a population's characteristics such as age, ethnicity, and gender.
- Demographic data is a statistical representation of socioeconomic information such as employment, education, income, marriage rates, birth and death rates, and so on.
- Age, race, ethnicity, gender, marital status, income, education, and occupation are some examples of demographic information. With survey questions, you may quickly and efficiently collect this sort of information.

A circle is 360°. So 360/12= 30°. Hope that helps.
1/4 y = 13
y = 13 x 4
y = 52
answer is C. 52
