At 1:00 the water level in a pool is 13 inches at 2:30 in the water level is 28 inches what is the rate of change

1 answer:

4 0

Let x = time, hours, from 1:00
Let y = water level, inches

Note that from 1:00 to 2:30, x = 2.5 - 1.0 = 1.5 hours.

The given data is
x: 0 1.5
y: 13 28.0

The change in x is 1.5 - 0 = 1.5 hours
he change in y is 28 - 13 = 15 inches

The rate of change is (15 inches)/(1.5 hours) = 10 inches/hour

Answer: 10 inches per hour

Each step subtracts 3 from the previous number.

11 - 3 = 8

The sequence will continue:

8 - 3 = 5

5 - 3 = 2

2 - 3 = -1

Etc.

What is the output, or y-value, when you input x = 1 into the function:

Aleksandr [31]

Answer: $y=-6$

Step-by-step explanation:

By definition, a relation is a function if and only if each input value has one and only one output value.

For this exercise it is important to remember that thw "Input values" are the values of the variable "x"and the "Output values" are the values of the variable"y".

In this case you have the following function provided in the exercise:

$y = x^4 - 2x^3 + x^2 + 4x - 10$

Then, to solve this exercise, you need to follow these steps:

Step 1. You have to substitute $x=1$ into the function given.

Step 2. Finally, you must evaluate in order to find the corresponding output value (or the value of the variable "y")

You get that this is:

$y = (1)^4 - 2(1)^3 + (1)^2 + 4(1) - 10\\\\y=-6$

Aloiza [94]

Because it is a question asking for ppl playing either soccer OR basketball, we add the two fractions together. Thus, Part A becomes 3/10 + 4/10, which is 7/10 (since the denominators are the same, you only add the numerators).
