Answer:
Step-by-step explanation:
(0,2\5)
Slope=4\5
X(4\5)=y-2\5
Y=(4\5)x +2\5
One of the product rules for exponents was used.

Or, you can consider that the definition of an exponent and the associative and commutative properties of multiplication were used.
Answer:
(x+2)^2 +(y-3)^2 = 9
Step-by-step explanation:
(x-h)^2 +(y-k)^2 = r^2
Where (h, k) is the center of the circle
And r is the radius of the circle.
Hope this helps.
Answer:
Initial temperature;
432.76
Common ratio;
-0.067
Equation;

Step-by-step explanation:
In this scenario, the time in minutes represents the independent variable x while the temperature of the pizza represents the dependent variable y.
The analysis is performed in Ms. Excel. The first step is to obtain a scatter plot of the data then finally inserting an exponential trend line to obtain the required equation.
The Ms. Excel output is shown in the attachment below. To obtain the initial temperature we substitute x = 0 in the equation. On the other hand, the common ratio is the exponent in the equation.
The answer would be 15h+25 because h isthe variable representing hours and they charge $15 for every hour. And also, the plus 25 is for the setup fee.
