Answer:
The answer is 4 and -5.
Step-by-step explanation:
Working under the assumption that the first term is not 2x, but 2x², you can find the zero values by factoring the expression:
With it factored we can see that x being equal to -5 or 4 will give a zero value
Let's also see it plotted, as the question said to use a graphing calculator:
Answer:
10 minutes would be 120 candy bars.
1 minute would be 12 candy bars.
7 minutes would be 84 candy bars.
Step-by-step explanation:
For 10 minutes you multiply 60 times 2, which would be 120 candy bars.
For 1 minute you divide 60 by 5, which would be 12 candy bars.
For 7 minutes you would add 60 and 24, which would be 84 candy bars.
Answer:
42
Step-by-step explanation:
Note that if
, then
, and so we can collapse the system of ODEs into a linear ODE:
which is a pretty standard linear ODE with constant coefficients. We have characteristic equation
so that the characteristic solution is
Now let's suppose the particular solution is
. Then
and so
Thus the general solution for
is
and you can find the solution
by simply differentiating
.
1. (The base on top is 15 ft.
To find the base on the bottom you have to first find the length of the right side of the triangle. 7 - 4 = 3. Then, square both sides of the triangle and add them together. 15^2 + 3^2 = 234
Next take 234 and find its square root = 15.3. The bases of the trapezoid are 15 and 15.3)
2. (Both bases and the height.)
3. (2l + 2w does not belong, all of the equations are formulas for area but that one is perimeter)
