6.40 im not sure but i think

Answer:

224π

Step-by-step explanation:

2πrh+2π\(r^{2}\) is the formula for finding the surface area of a cylinder.

14 ft is the diameter, so 7 ft would be the radius (r).

9 ft is the height (h).

Substitute in your values.  2π x 7 x 9 + 2π\(7^{2}\)  = 703.717 or 224π

Answer:

number 3 (aka c)

Step-by-step explanation:

all other options have the same input twice but different outputs. that emans they arent functions

Answer:

B

Step-by-step explanation:

I'm really not sure how to explain this.

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answer:

#3 points are
(-4, 2)
(4, 2)

(-4, -2)

(4, 0)

#4 scale factor = 1/4

#5 scale factor = 1/2

Step-by-step explanation:

#3

take the given points and multiply the x and y by 2/3

#4 take any point and compare it to a similar point on the dilated graph. for example, you take a point from the original graph (-2, 4) and a point from the dilated graph (-1/2, 1) since you multiply -2 by 1/4 to get -1/2, that is your scale factor.

#5 same as #4 but with different points

Answer:

Step-by-step explanation:

I'm going to start off with three graphed points. (2 to answer, 1 to check)

I'll take (6,3),(8,4), and (10,5)

look at the relationship between the x and y values.

6/2=3

8/2=4

10/2=5

replace with x and y values.

x/2=y

so y=x/2 or 1/2x.

Step-by-step explanation:

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Step-by-step explanation:

b^2 = 6^2 + 11^2 - 2*6*11cos 109  =   199.97

b =  14.1  to nearest tenth.

now use sine rule to find the value of < A

14.14 / sin 109 = 6 /  sin A

<A =  24 degrees

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Answer:

2t³

Step-by-step explanation:

For this problem, we are dividing 16t⁴ by 8t. First, we should separate both of these terms into parts we can work with individually. So, we can easily divide 16 by 8, and we can also easily divide t⁴ by t. After solving each of these smaller problems we can get our solution.

First, 16 divided by 8 is 2. This is the first part of our answer. t⁴ divided by t is t³; this is because when dividing terms with the same base, we can subtract the exponents to get the final exponent. The exponent for t⁴ is 4, and the exponent for t is an invisible 1 (t = t¹). 4 - 1 = 3, so t⁴ divided by t is t³.

Putting those two answers together gives us 2t³.
