a quadratic function given the roots (3,0) and (-1,0) and the point (-3,3)
when p and q are the roots then we use equation
y = a(x- p)(x-q)
We are given with roots 3 and -1
y = a(x- 3)(x-(-1))
y = a(x- 3)(x + 1)
Now we use the given point (-3,3) to find out 'a'
3 = a(-3- 3)(-3 + 1)
3= a(-6)(-2)
3= 12a
divide by 12 on both sides
Replace the value of 'a'
Because the absolute value of something can't be a negative number, there is no solution.
Answer:
102-105
Step-by-step explanation:
Median formula for a group data is expressed as shown;
Median = (N+1)/2 th value/interval
N is the total number of students
From the question N = 36
Median = (36+1)/2
Median = 37/2
Median = 18.5
Therefore we are to cumulate the value of the frequency up till the 18.5th value.
From the table
If we keep cummulating the frequency from the top;
Let's add:
1+3+5+5+8 = 21
Since the 18.5th values falls within the cumulative frequency value (i.e 21), the corresponding interval where we stopped cumulating will be our Median.
From the table, the interval with the frequency of 8 is 102 - 105. Hence the median is located at the interval 102 - 105
You need the total amount of how many animals
Answer:
∠1 only
Step-by-step explanation:
Complementary angles:
- sum to 90°
- form a right angle
The only angle (that's an answer choice) that helps form a right angle with angle 2 is angle 1, thus making it the correct answer.
