The easiest way to do this is to put each term in the numerator over the denominator and do the division/reducing for each one. Like this:
. The first term reduces to
, the second to
, and the third to 3. Putting them all together with the signs in between we have
Answer:
d. y = (x +2)(x -3)
Step-by-step explanation:
When p is a zero of the function (an x-intercept), the function has (x -p) as a factor.
Here, the x-intercepts are x = -2 and x = 3. This means the factors of the function are (x -(-2)) = (x +2) and (x -3).
y = (x +2)(x -3)
first to find average age add all the ages divide by number of ages 4
5+4=9
9+6=15
15+39=54
54/4=13.5
For standard deviation find the mean/average
13.5
then subtract the mean from each number/age
5-13.5=-8.5
4-13.5=-9.5
6-13.5=-7.5
39-13.5=25.5
then square each number
-8.5^2=-72.25
-9.5^2=-90.25
-7.5^2=-56.25
25.5^2=650.25
then find the mean/average of the new numbers
-72.25+-90.25+-56.25+650.25=431.5
431.5/4=107.85
then take the square root of the new mean/average
(2,2), you can verify this by doing the midpoint formula (which i forgot) or drawing a graph
Answer: 3.83m^3
Step-by-step explanation:
Use formula for volume of a triangular prism (Area of triangle times length of the figure)
