Answer:

98 $\pi$ /3

Step-by-step explanation:

The shaded area of the circle is 1/6 of the area of a circle.

The area of a circle is ( $\pi$ *r^2)/2

We are given that the diameter is 28 m. So the radius(r) is 14 m.

The area of the circle is ( $\pi$ *(14)^2)/2 = 196 $\pi$ .

Since the shaded area is 1/6 of the circle,

196 $\pi$ /6 = 98 $\pi$ /3.

Question 2 (2 points)

hoa [83]

Answer:

4) The limit does not exist.

General Formulas and Concepts:

Calculus

Limits

Right-Side Limit: $\displaystyle \lim_{x \to c^+} f(x)$
Left-Side Limit: $\displaystyle \lim_{x \to c^-} f(x)$

Limit Rule [Variable Direct Substitution]: $\displaystyle \lim_{x \to c} x = c$

Step-by-step explanation:

*Note:

For a limit to exist, the right-side and left-side limits must be equal to each other.

Step 1: Define

Identify

$\displaystyle f(x) = \left\{\begin{array}{ccc}5 - x ,\ x < 5\\8 ,\ x = 5\\x + 3 ,\ x > 5\end{array}$

Step 2: Find Left-Side Limit

Substitute in function [Left-Side Limit]: $\displaystyle \lim_{x \to 5^-} 5 - x$
Evaluate limit [Limit Rule - Variable Direct Substitution]: $\displaystyle \lim_{x \to 5^-} 5 - x = 5- 5 = 0$

Step 2: Find Left-Side Limit

Substitute in function [Right-Side Limit]: $\displaystyle \lim_{x \to 5^+} x + 3$
Evaluate limit [Limit Rule - Variable Direct Substitution]: $\displaystyle \lim_{x \to 5^+} x + 3 = 5 + 3 = 8$

∴ since $\displaystyle \lim_{x \to c^+} f(x) \neq \lim_{x \to c^-} f(x)$ , $\displaystyle \lim_{x \to 5} f(x) = \text{DNE}$

Maria-Jose is a math tutor. She charges a one-time introduction fee of $25.00 and the cost of the tutoring sessions is shown bel

Feliz [49]

Answer:

y=6x+25

Step-by-step explanation:

y will be the whole cost. 6 is how many sessions you have and x is the cost of each of those sessions. The one time introduction fee is 25. you would add 25 plus 6 times the cost of sessions (x) and you would get your answer (y).

3/4 of a cake is left and is divided equally among four people. How much of the remaining cake does each person get?

Naily [24]

Answer:

each person can get 3/12 if you split the 3.4 twice.

Step-by-step explanation:

make a circle

split one line down the middle and the other horizontal.

color is one of the corners. you will not use it. this is the part of the cake they already ate.

now you have three remaining parts.

split each one of the remaining heart down the middle.

now you have six remaining slices.

6 is not divisible by 4.

split the sixths down the middle one more time.

now you should have 12.

12 is divisable by 4.

give each person 3 out of 12 slices of cake.

it is just enough to feed all 4 people.
