1 3/4 = 7/4....u take ur whole number (1) and multiply it by ur denominator (4)...which gives u 4...then add that to ur numerator (3), giving u 7...then put that over ur original denominator (4)....so it becomes 7/4
Answer:
sin⁴x - sin²x
sin²x(sin²x - 1)
(1 - cos²x)(1 - cos²x - 1)
(1 - cos²x)(-cos²x)
-cos²x + cos⁴x
cos⁴x - cos²x
Answer:
See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h)^2 - k = 0, the vertex is (h, -k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2)^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1)^2 = 2
(x - 1)^2 - 2 = 0
The vertex is (1, -2)
<span>f(x)= x^2+3x+5
</span><span>y-intercept when x = 0, so f(0) = 5
answer
</span><span>y-intercept </span>(0,5)
In order to know how much time will David and
Armando take, you need to write down the given and solve them with the given
solution.
David – 15 reports
Armando – 37 reports
Total Reports = 52 reports in total
Total Reports in an hour = 52
Overall total reports = 400
Time to finish = ?
If you try to evaluate, if you have 50 reports in
an hour with a total of 400 reports, you could have gain 8 hours by doing the
reports.
So to expand more, 52 reports will be divided
into 400, giving a total of 7.6
<span>So the answer is that they will take 7 hours
and a half in doing the reports.</span>
