Answer:

Your answer for F will be 13.

Step-by-step explanation:

Take 11.2 and add it to 1.8, and you will get 13 and 13 will be the variable (f). So, f (13) - 1.8 = 11.2

Hope this helps! :D

find the value of "a" and "b" for which the limit exists both as x approaches 1 and as x approaches 2:
lbvjy [14]

Answer:

a = 4

b = -2

Step-by-step explanation:

If the given function is continuous at x = 1

\lim_{x \to 1^{-}} f(x)=(x+1)

                     =2

\lim_{x \to 1^{+}} f(x)=ax+b

                     =a+b

\lim_{x \to 1} f(x)=ax+b

                   =a+b

And for the continuity of the function at x = 1,

\lim_{x \to 1^{-}} f(x)=\lim_{x \to 1^{+}} f(x)=\lim_{x \to 1} f(x)

Therefore, (a + b) = 2 -------(1)

If the function 'f' is continuous at x = 2,

\lim_{x \to 2^{-}} f(x)=ax+b

                     =2a+b

\lim_{x \to 2^{+}} f(x)=3x

                     =6

\lim_{x \to 2} f(x)=3x

                   =6

Therefore, \lim_{x \to 2^{-}} f(x)=\lim_{x \to 2^{+}} f(x)=\lim_{x \to 2} f(x)

2a + b = 6 -----(2)

Subtract equation (1) from (2),

(2a + b) - (a + b) = 6 - 2

a = 4

From equation (1),

4 + b = 2

b = -2

The Hydro water department has a monthly service charge of $10.10 and a volume charge of $1.58 for every 100 cubic feet of water
cluponka [151]

Answer:

B. a decrease in their water bill of $3.16.

Step-by-step explanation:

Monthly service charge =$10.10

Volume charge = $1.58 for every 100 cubic feet of water.

Total monthly cost = 1.58x + 10.10

If the Johnson family used 200ft^3 less water this month than last month, then they can expect a reduction in their bill by the Volume charge for  200ft^3.

Volume Charge per 100ft^3 of water = $1.58

Therefore: Volume Charge for 200ft^3 of water = 2 X $1.58=$3.16

Therefore, the Johnson family can expect a decrease in their water bill of $3.16.
