Urgent please help with finding rate of change

Mathematics
1 answer:
boyakko [2]3 years ago
5 0

When working with functions (of all types), the average rate of change is expressed using function notation:

\dfrac{f(b)-f(a)}{b-a}.

For the interval from x=7 to x=8,

1. find f(7) and f(8):

  • f(7)=729\cdot 3=2187;
  • f(8)=2187\cdot 3=6561;

2. use given formula:

\dfrac{f(8)-f(7)}{8-7}=\dfrac{6561-2187}{8-7}=4374.

Answer: the average rate of change for the interval from x=7 to x=8 is 4374.

Answer:

2,4,6 and 8 are all 40degrees that means 1,3,5 and 7 are 140 degrees. 2,4,6, and 8 are at a diagonal that allows them to equal eachother. because 2 is given 40degrees as the angle 4,6 and 8 must also be 40 degrees. a flat line is 180 degrees. 180-40=140

you have vertical angles alternate interior, alternate exterior

Step-by-step explanation:

Vertical Angles: a pair of opposite congruent non-adjacent angles formed by intersecting lines; share a vertex

Alternate Interior: when a transversal intersects two lines, alternate interior angles are on opposite sides of the transversal and on the inside of the given lines

Alternate Exterior: when a transversal intersects two lines, alternate exterior angles are on opposite sides of the transversal and on the outside of the given lines  They are congruent.

For first pound it is = $2.41
For next six, = 0.41 * 6 = $2.46

Remaining = 7.99 - (2.41 + 2.46) = 7.99 - 4.87 = 3.12

Now, additional pounds = 3.12 / 0.39 = 8
Total weight = 1 + 6 + 8 = 15

In short, Your Answer would be 15 pounds

Hope this helps!
