An hour and 15 minutes I believe which would be 1 and 1/4
Answer: y=-0.6x^3- 1
Step-by-step explanation:
In the graph, first we must see the points where the line intersects the axis.
We can see that it goes throug the point (0, -1)
Now, of the given options the only two that are 0 when x is -1, are:
f1(x) =y = 0.6*x^2 - 1
f2(x) =y = -0.6x^3 - 1
We also can see that for all the positive values of x, y has a negative value, so let's value bot functions in x = 2, and see what happens.
f1(2) = 0.6*4 - 1 = 1.4
f2(2) = -0.6*8 - 1 = -5.8
so the correct option is
y=-0.6x^3- 1
Power = Current *Voltage
You already have the current, but not the voltage.
But you are given resistance, and you know that
Voltage=Current*Resistance
Therefore
V=I*R=4*12=48V
So you have 48V
Now you can figure out the Power
P=I*V=4*48=192W
Therefore you have 192W.
hope this helps
Let's rewrite the system of equations:
y = three over four times x squared minus 3
y = (3/4) x ^ 2 - 3
y = negative three over four times x squared plus 3
y = (-3/4) x ^ 2 + 3
The system of equations is:
y = (3/4) x ^ 2 - 3
y = (-3/4) x ^ 2 + 3
The solutions are:
(-2, 0)
(2, 0)

Answer: C. 2n+1
Step-by-step explanation:
The sequence of numbers is
3,5,7,9
The terms are increasing at a linear rate. This means that it is an arithmetic progression. The difference between two successive terms is constant. This is the common difference. The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
Tn is the nth term of the arithmetic sequence.
d is the common difference of the arithmetic sequence.
n is the number of terms in the arithmetic sequence.
From the information given
a = 3
d = 5 - 3 = 7 - 5 = 9 - 7 = 2
Tn = 3 + 2(n - 1)
Tn = 3 + 2n - 2
Tn = 3 - 2 + 2n
Tn = 2n + 1
