Not enough info here to enable us to find a numerical answer. We don't know how many cars make up the train.
Suppose that c cars make up the train.
Then the number of seats on this train is 4(c-1) + 2.
Example: if there are a total of 3 cars, the # of seats is 4(2) + 2, or 10:
4 seats in the first car, 4 seats in the second car, and 2 seats in the third car.
Answer:
the question is incomplete, the complete question is "Finding second Derivatives In Exercise,find the second derivate.
"
answer:,
Step-by-step explanation:
To determine the second derivative, we differentiate twice.
for the first differentiation, we use the product rule approach. i.e
from if w assign
u(x)=(3+2x) and the derivative,
also and the derivative .
If we substitute values we arrive at
,
Now to determine the second derivative we use the product rule again
this time, u(x)=(7+6x) and the derivative,
also and the derivative .
If we substitute values we arrive at
,
Before determining the equation of the circle, we must determine first the radius of the circle and its center point.
Radius of the circle:
We find the distance between points R and S and divide it to 2. To find the distance between two points, the equation is
d = √[(x2 - x1)²+(y2 - y1)²]
d = √[(4 - -2)²+(2 - 2)²]
d = 6
r = 6/2
r = 3
Then, we find the centerpoint by finding the midpoint of both points, since the center of a diameter is the center of the circle. Let centerpoint be (h,k). The formula would be
h = (x1 +x2)/2 = (-2+4)/2 = 1
k = (y1 + y2)/2 = (2+2)/2 = 2
Now that we know all parameters, we substitute this to the standard equation for a circle:
(x - h)² + (y - k)² = r²
(x-1)² + (y - 2)² = 3²
The equation of the circle would be (x-1)² + (y - 2)² = 9
I think it might be angle 3.
