Answer:
1: C, ten from each class
2: 27
3: the numbers are counted incorrectly.
4: 5.5 hours
5: 6 hours
Step-by-step explanation:
A = e; b = 2 f; n = 10.
The fourth term is:
T 4 = T (3+1) = ( 10 * 9 * 8 ) / ( 3 * 2 * 1 ) * e^7 * ( 2 f ) ^3 =
= 120 * e^7 * 2^3 * b^3 =
= 120 * 8 * e^7 * b^3 =
= 960 * e^7 * b^3
Answer:
C
Step-by-step explanation:
the factor of x in the equation is the slope, which is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
going from the left point to the right point x changes by +3 units, and y changes by -1 unit.
so, the slope (and factor of x in the equation) is -1/3.
and the constant term in the equation is the y (axis) intercept of the line.
this is the y value, when x = 0 (intercepting the y axis).
and we see in the graph, when x = 0, the line goes through y = 2.
so, the equation has to be
y = -1/3 × x + 2
therefore, C is the right answer.
v= 3.14r^2 x h
