1) $2\cdot 3=6;$

2) $10+2\cdot 3=10+6=16;$

3) $(10+2\cdot 3)^2=16^2=256;$

4) $(10+2\cdot 3)^2-2=256-2=254.$

Answer: $(10+2\cdot 3)^2-2=254.$

An artist cuts the bottom 4 inches from an empty sphere with a radius of 12 inches to make a bowl. How long, to the nearest tent

Zolol [24]

We have been given that an artist cuts the bottom 4 inches from an empty sphere with a radius of 12 inches to make a bowl. We are asked to find the length of the rim of the bowl.

The rim of the bowl will be equal to the perimeter of circle with radius of 12 inches.

$\text{Perimeter of circle}=2\pi r$ , where r represents radius of circle.

$\text{Perimeter of circle}=2\pi (12\text{ inches})$

$\text{Perimeter of circle}=24\pi \text{ inches}$

$\text{Perimeter of circle}=75.39822 \text{ inches}$

$\text{Perimeter of circle}\approx 75.4 \text{ inches}$

Therefore, the rim of the bowl is approximately 75.4 inches.

Determine if the following table represents a quadratic function.

snow_tiger [21]

Answer:

The options are not visible enough (See Explanation)

Step-by-step explanation:

Given

x:- 1 || 2 || 3 || 4 || 5

y:- 13 || 22 || 37 || 58 || 85

Required

Determine if the function is quadratic

Calculate the difference between the values of y

$Difference = 22 - 13 = 9$

$Difference = 37 - 22 = 15$

$Difference = 58 - 37 = 21$

$Difference = 85 - 58 = 27$

The resulting difference are: 9 || 15 || 21 || 27

Next; Calculate the difference between the difference of values of y

$Difference = 15 - 9 = 6$

$Difference = 21 - 15 = 6$

$Difference = 27 - 21 = 6$

The resulting difference are: 6 || 6 || 6

For the function to be quadratic, the above difference must be the same and since they are the same (6), then the function represents a quadratic function.
