Answer:

77.112

Step-by-step explanation:

circle area A=pirsquared so A= 3.142×6×6= 113.112

rectangle area A= 6×6=36

shaded area= 113.112-36=77.112

Which equation is true for the three pairs of x- and y- values in the table

gizmo_the_mogwai [7]

Answer:

1. -2+2x=y

Step-by-step explanation:

You only need to try the first two lines of the table to determine which equation works.

Only equations 1 and 4 work for the first line of the table (x=0).

1. -2 +2·0 = -2 . . . . . . . this works
2. 2 -2·0 = 2 ≠ -2
3. 2 +2·0 = 2 ≠ -2
4. -2 +0 = -2 . . . . . . . this works

Of those, only equation 1 works for the second line of the table (x=1).

1. -2 +2·1 = 0 . . . . . . . this works
4. -2 +1 = -1 ≠ 0

The equation that is true for the table values is ...

-2 +2x = y

How is the behavior of food coloring in the cool and

madreJ [45]

Answer:

Food color mixes faster in warm water than in cold water.

Molecules in a liquid have enough energy to move around and pass each other. This is why water can flow and take the shape of the container you pour it into.

Warm water has more heat energy than cold water, which makes the molecules in warm water move faster than molecules in cold water. The food coloring you add to the water is pushed around by the water molecules. Since the molecules in warm water move around faster, the food coloring spreads out quicker in the warm water than in the cold water.

adelina 88 [10]

Answer:

2 miles = 3,520 yards

first we need to find how many yards she's walked already :

400×5=2,000 yards

now subtract :

3,520-2,000= 1,520 yards

Keisha needs to walk 1,520 more yards to complete 2 miles

hope this helped

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