Need help solving this limit problem.

Mathematics
1 answer:
evablogger [386]4 years ago

Answer:

c= -1.8

Step-by-step explanation:

A function is continuous at a point x if the limits at x from above and below coincide (are equal). Hence,

Limit from above: \lim_{x\rightarrow\-1^+}f(x)=4c(-1)=6 = -4c-6

Limit from below: \lim_{x\rightarrow\-1^-}f(x)=c(-1)^2+3=c+3

And so when these limits are equal we obtain

c+3=-4c-6\\5c=-9\\c=-1.8

Answer:

2 / 6

Step-by-step explanation:

Fraction of red beads on braid = 1/3

greatest number of braids = 12

Fraction of red beads = (1 /3) * 12 = 4 red beads

Kazeer [188]

Answer:

<h2>33k - 25</h2>

Step-by-step explanation:

-5(1 - 5k) - 4(2k + 5)      <em>use distributive property a(b + c) = ab + ac</em>

= (-5)(1) + (-5)(-5k) + (-4)(2k) + (-4)(5)

= -5 + 25k - 8k - 20           <em>combine like terms</em>

= (25k - 8k) + (-5 - 20)

= 33k - 25

Ivanshal [37]

Answer:

The exact number would be 26.66666667 but it would be 26.

Step-by-step explanation:

Usually when dealing with decimals anything 5 and up would be rounded up but since we are dealing with money we don't round up. Since his friends lunch cost $3 every lunch the most he will be able to buy is 26. He will have about $2.5 left over which he cannot buy a lunch with so thats why you dont round up.
