Answer:

Step-by-step explanation:

Regular charge- $20                                      

Every hour of service cost- $40

Equation or slope intercept form-

C= 40h+20

Part 1-  20+40(8)=

40 multiplied by 8                320+20         = $340

Part 2-  20+40(10)=

40 multiplied by 10             400+20           = $420

Help me pleasseeeee!!! its about algebraic properties of limits!

\text{Hello there! :)}

3. \sqrt{2} \\\\\text{4.  0}\\\\\text{5.  dne}

\text{To find the overall limit, they must approach the same y-value from each side:}

\\\\3.  \lim_{x \to \frac{\pi }{4} } 2sinx ={\sqrt{2}

\text{Therefore:}\\\\3.  \lim_{x \to \frac{\pi }{4} } f(x)= {\sqrt{2} }

\text{For this question, evaluate the limit from the RIGHT-HAND side:}\\\\4.   \lim_{x \to \pi +} f(x)\\\\ \text{Use the equation tanx to evaluate since it involves values greater than \pi:}\\\\

\lim_{x \to \pi +} tanx = 0\\\\\text{So:}\\\\ \lim_{x \to \pi +} f(x) = 0

5.  \\\\\text{Evaluate the overall limit. Make sure both sides approach the same y=value:}\\\\ \lim_{x \to \pi } 2cosx= -2\\\\ \lim_{x \to \pi } tanx = 0\\\\ \text{ Therefore:}\\ \lim_{x \to \pi } f(x) = dne \text{ (Does not exist})

s344n2d4d5 [400]

Answer:

The first answer is correct.

(x + 1)^2 + (y - 2)^2 = 1

A circle with the midpoint M(Mx, My) and the radius r can be written as

(x - Mx)^2 + (y - My)^2 = r^2
