Answer:
all real numbers greater can or equal to -1
Step-by-step explanation:
Given the function: f(x) = (x - 4)(x - 2)
=> its root: x =4 and x = 2
We convert the factored form into standard form: f(x) = 
As can be seen, the parameter a in the function is positive => the graph of it open up over its domain.
and then we convert the factored form into vertex form: f(x) = 
- 1
<=> when x =3 we have f(x) =1 and f(x) =-1 is the lowest point of the function
=> the range of the function: all real numbers greater can or equal to -1
Hope it will find you well.
Answer: D. 0.981
Step-by-step explanation:
Step 1: For the given data table on x^2
We square all values given to us
Step 2: we repeat Same for Y^2 table too.
Step 3: XY table we multiply x and y
Step 4: we make a summation of them all
Step 5: we input our summer value into our formula.
Step 6 : we arrive at our answer which is 0.981
We are given with the function summation of 16*(5) ^(I-1) from 1 to infinity. As we assume in the calculator that infinity is equal to a very large number, the result that can be obtained is undefined. This means the number is very large. This is because the ratio (15) is large too. The series is divergent since the number in the infinite geometric series is ever increasing. Answer is B.
The answers you have for each of them are right
Answer:
5/12
Step-by-step explanation:
15 students went to hear the doctor speak and 21 students went to other sessions
How many students are there? 15 + 21 = 36 students
Therefore, the probability to randomly select a student that went to hear the doctor is 
, then simplifying it by 3 is 
.
If we want to express it in percentage it would be 41.6%
