Step-by-step explanation:
Answer:
Smart phone sales since 1990:- linear function
Half life of a pesticide :- exponential function
Step-by-step explanation:
Linear function can be applicable in almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit, therefore smart phone sales since 1990 can be model with linear function
Exponential functions can be applicable in social, scientific, or personal finance situations such as population growth, radioactive decay and half life, therefore half life of pesticide can be model with exponential function.
Answer:

Step-by-step explanation:
From the question we are told that:
Exponential distribution mean 
Distance 
Generally the equation for Exponential distribution is mathematically given by


Therefore
Possion Y


Generally the equation for The probability that there are no major cracks in a 10 mile stretch of the highway is mathematically given by



Answer: y=9x + 26
Step-by-step explanation:
Notice that for two lines to be parallel they must have the same slopes but different y intercept.
So the equation y =9x + 2 has a slope of 9 and y-intercept of 2 so using the points we can determine the y intercept of the line parallel to it to find the.
Using the slope intercept form formula which is y = mx + b we can plot in the slope and the given coordinates to solve for b.
The coordinate is (-2,8) which the y value is 8 and the x value is -2
so 8 = 9(-2) +b solve for b
8 = -18 + b
+18 +18
b = 26
The y intercept is 26 so the equation will be y=9x + 26
Answer:
Step-by-step explanation:
Theyre basically telling you that x = (a + 2)
All you have to do is replace x with a + 2

Next you have to simplify, 2+5 = 7 to get 3(a+7). Apply the distributive property to get 3a + 21. Your new equation is now:

Now here's the issue, you cant add those two terms yet because we need a common denominator. Multiply the numerator and denominator of 3a + 21 by a+2 to get:

You gotta now apply FOIL to get:

There is your answer
