Answer:
2b²(8b²+15b-6)
Step-by-step explanation:
16+30b³-12b²
2b²(8b²+15b-6)
This is not further factorable. If you want to find the roots, you'd have to use the quadratic formula for the polynomial in the parentheses. Therefore that is our final answer.
Step-by-step explanation:
From the statement:
M: is total to be memorized
A(t): the amount memorized.
The key issue is translate this statement as equation "rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized"
memorizing rate is .
the amount that is left to be memorized can be expressed as the total minus the amount memorized, that is .
So we can write
And that would be the differential equation for A(t).
Answer:
60 degrees
Step-by-step explanation:
If each side of the triangle WRD is 3 inches long, then WRD is an equilateral triangle, meaning all angles are the same size. Since there are 180 degrees in a triangle, 180/3 = 60 degrees.
There is no single solution but there is a group of solutions also known as the interval.
This can be written with an interval.
Hope this helps.
