Need help evaluating the limits for this problem.

Mathematics
1 answer:
TEA [102]3 years ago
4 0

Answer:

  • a)  c
  • b)  c
  • c)  c
  • d)  DNE

Step-by-step explanation:

There is nothing about the definition of q(x) that keeps you from evaluating the limit by substituting the value b for x in the appropriate definition.

a) from the left: lim = a(b -b)^3 +c = 0 + c = c

b) from the right: lim = a(b -b) +c = 0 + c = c

c) the limit from the left is equal to the limit from the right, so the limit exists and is that value: c.

d) the function is undefined at x=b, so q(b) does not exist. (The graph has a hole at that point.)

Which is the slope of the line that passes through the points (3,17)(3,17) and (7,25)(7,25)?
PilotLPTM [1.2K]
The slope is 2, because you subtract the points 3,17 from 7,25 to get 8/4/ Simplify that into 2.

Martha is carrying her biology, science, and math textbooks. Her books weigh a total of 9 pounds. Her biology textbook weighs 3
Nata [24]
1 pound = 16 oz
Her books weigh 9 pounds or (9)(16)= 144 oz
Math Textbook= 40 oz
Biology textbook= 3 pounds or (3)(16)= 48 oz

Total weight of books - math textbook - biology textbook = science textbook
144-40-48 = 56oz
science textbook = 56oz

Solve for X. Geometry
kozerog [31]
So since they are similar
AC/BC=CD/CE

so
(66-x)/30=(x+4)/5
times both sides by 5
(66-x)/6=x+4
times both sides by 6
66-x=6(x+4)
distribute
66-x=6x+24
add x to both sides
66=7x+24
minus 24 from both sides
42=7x
divide both sides by 7
6=x
x=6 units
