A = 0.3 recursive = 3/9

b = 0.5 recursive = 5/9

a + b = 3/9 + 5/9 = 8/9

Answer: 8/9

8/10 is the answer i think I"m right Because 0.3+0.5=0.8 so 8/10=0.8 so that's why i think 8/10 is the answer.

Marta Kellogg, a health care worker, has an hourly pay rate of $15.40

Zigmanuir [339]

Answer:

$685.30

Step-by-step explanation:

Her hourly pay is $15.40

Her overtime pay is 1.5 x $15.40 = $23.10

She works 37 normal hours = 37 x $ 15.40 = $569.80

She works 5 overtime hours = 5 x $23.10 = $115.50

Adding her normal + overtime = $569.80 + $115.50 = $685.30

Hope this helps! Let me know if you have any questions :)

If f(x) = ln(2), then limx--->2 (f(2)-f(x))/x-2

Blizzard [7]

Answer:

as written, -2
with denominator parentheses, 0
with f(x)=ln(x) and denominator parentheses, -1/2

Step-by-step explanation:

The problem as stated asks for the limit as x approaches 2 of (0/x) -2.

As written, the limit is (0/2) -2 = -2.

Explanation: f(x) is a constant, so the numerator is 0. The ratio 0/x -2 is defined as -2 everywhere except x=0. So, the value at x=2 is 0/2 -2 = -2.

If you mean (f(2) -f(x))/(x -2), that limit is the limit of 0/(x-2) = 0 as x approaches 2.

Explanation: f(x) is a constant, so the numerator is 0. The ratio 0/(x-2) is zero everywhere except at x=2. The left limit and right limit are both 0 as x approaches 2. Since these limits agree, the limit is said to be 0.

If you mean f(x) = ln(x) and you want the limit of (f(2) -f(x))/(x -2), that value will be -1/2.

Explanation: The value of the ratio is 0/0 at x=2, so we can find the limit using L'Hôpital's rule. Differentiating numerator and denominator, we have ...

lim = (-1/x)/(1)

The value is -1/2 at x=2.
