Answer:

Associative Property

Step-by-step explanation:

In your equation, you're adding three digits together.

When you're adding or multiplying, the order in which you it doesn't matter:

ex.  1 + 3 + 5  =  3 + 5 + 1   <- This is the commutative property (not associative)

Adding parentheses indicated the order in which you do an operation, but when adding, order doesn't matter, so you're able to move around the parentheses. When you move around the parentheses, that's an example of the associative property.

It's important to not confuse the associative property with the commutative property.

The associative property is moving around parentheses

While the commutative property is moving around the numbers.

Equation of a circle:

(x - h)^2 + (y - k)^2 = r^2


In this case:

<span>center (2,7) and radius 4 so h = 2, k = 7 and r = 4

</span>Equation:

(x - 2)^2 + (y - 7)^2 = 4^2

(x - 2)^2 + (y - 7)^2 = 16

T models the temperature (in degrees Celsius) in New York City when it's t hours after midnight on a given day. Match each state
Klio2033 [76]

Answer:

Please check explanation

Step-by-step explanation:

Here, we want to do a matching.

We shall be matching the given statements with the features we have on the graph

Hence we shall be looking closely at the graph to answer the questions.

The y-intercept is the point at which the graph touches the y-axis

And it was at -3 degrees celsius at the beginning of the day.

The temperature was above zero between 8am and 8pm. The matching statement is that it is increasing or decreasing interval

We can see that the graph rose from 8am before it finally comes to zero at 8pm

Positive or negative interval matches with it was getting warmer between 2am and 2pm.

While temperature was lowest at 2am, we can see a peak at 2pm.

The average annual income, I, in dollars, of a lawyer with an age of x years is modeled with the following function:
Eduardwww [97]
I = -425x^2 + 45500x - 650000
For I to be maximum, dI/dx = 0
dI/dx = -850x + 45500 = 0
x = 45500/850 = 53.53

Therefore, maximum I = -425(53.53)^2 + 45500(53.53) - 650000 = 567,794.11

Therefore, <span>the maximum average annual income, in dollars, a lawyer can earn</span>  is $567,794
