Answer:
4 2/15
Step-by-step explanation:
okay so let's first change 1/3 and 1/5 into the same fraction,
the common denominator, is 15
3 times 5, to get to fifteen,
so
5/15 and 3/15
minus eachother
2/15
6-2 is 4
4 2/15
Answer:
The school C shows the greatest rate of change between male and female students
Step-by-step explanation:
Let
x -----> the number of female students
y ----> the number of male students
we know that
The ratio of male students to female students is
we have
<em>School A</em>
<em>School B</em>
----> the slope of the linear equation
<em>School C</em>
so
therefore
The school C shows the greatest rate of change between male and female students
Answer:
One thousand five hundred
The object reaches the lowest height at 5 seconds
<h3>How to determine the time?</h3>
The function is given as:
f(t) = -2t² +22t + 6
Differentiate the function
f'(t) = -4t +22
Set to 0
-4t +22 = 0
Subtract 22 from both sides
-4t = -22
Divide both sides by -4
t = 5.5
Remove decimal points
t = 5
Hence, the object reaches the lowest height at 5 seconds

Only x-intercept because if you want to know about x-intercepts so y will be zero (y=0)
then 0 =4x^2 -12x + 9
0=(2x-3)(2x-3)
0=2x-3
so x=3/2 that is x-intercept
