If you do cross multiplication and multiply 90 by 2 then divide that answer with 30, your answer should be 6

What is the difference between rates and proportions???

frez [133]

A rate often involves time: e. g., 33 feet per second; also, we are finding the ratio of one type of measurement with respect to another: distance and time.

A proportion is often the ratio of different measures of the same thing:

e. g. 5 apples
------------
7 apples

Question: State whether each table of values represents a function

Mashcka [7]

Answer:

Please check the explanation.

Step-by-step explanation:

As we know that the values in the table represent a function only if there there is only 1 input for every output.

Given the table 1

x y

-12 2

-10 10

0 -2

5 -6

8 -11

15 -15

From the table, it is clear that for each input there exists a unique output.

i.e.

According to the given table,

y = 2 at x=-12

y = 10 at x=-1 0

y = -1 at x=0

y = -11 at x=8

y = -15 at x=15

From the table, it is clear that for each input x, it has a unique output y.

Hence, table 1 is a function.

Given the table 2

x y

9 -18

-20 0

-6 1

-17 16

9 17

11 19

This table does not produce a function, because the input x=9 produces two outputs.

i.e.

at x = 9, the y = -18

at x = 9, the y = 17

Therefore, the table 2 does not represent a function.

Find the area of a regular hexagon with a 48- inch perimeter

solmaris [256]

First, you must find the side length. It is a hexagon so there are 6 sides. You take the perimeter by 6 48/6 and get 8. Then plug it into formula (3 sqrt 3)/2 a^2 where a is side length. Plug into formula and get an answer of 166.28 in^2

Answer:

- time = 1second

- maximum height = 16m

Step-by-step explanation:

Given the height of a pumpkin t seconds after it is launched from a catapult modelled by the equation

f(t)=-16t²+32t... (1)

The pumpkin reaches its maximum height when the velocity is zero.

Velocity = {d(f(x)}/dt = -32t+32

Since v = 0m/s (at maximum height)

-32t+32 = 0

-32t = -32

t = -32/-32

t = 1sec

The pumpkin reaches its maximum height after 1second.

Maximum height of the pumpkin is gotten by substituting t = 1sec into equation (1)

f(1) = -16(1)²+32(1)

f(1) = -16+32

f(1) = 16m

The maximum height of the pumpkin is 16m
