Find the average rate of change of the tree over time. In 1965 the tree has a diameter of 135 in. And in 2005 it has a diameter of 139 in. B)Predict the diameter in 2035.
Answer:
0.1 in per year ; 142 in
Step-by-step explanation:
Giveb that :
Diameter of tree in 1965 = 135 inches
Diameter of tree in 2005 = 139 inches
Average rate of change:
Change in diameter / change in time
(139 - 135) / (2005 - 1965)
4 / 40
= 0.1 in per year
Predict diameter in 2035;
Initial diameter + (average rate of change * (Number of years from initial)).
135 in + (0. 1 * (2035 - 1965))
135 in + (0.1 * 70)
135 in + 7 in
= 142 in

The statement supported the graph is
The axis of symmetry is x = 3
The coordinates of the y-intercept are (0,7)
What is axis of symmetry?A line that divides an object into two equal halves and produces a mirror-like reflection of each side of the object is known as an axis of symmetry.
1. The axis of symmetry is x = 3
The axis of symmetry is the central axis of the graph, which signifies the middle point of the graph. It is evident that this graph is centered on x = 3.
2. The coordinates of the y-intercept are (0,7)
The y intercept is the point where the graph meets the y-axis, that is, the value of y on the graph when x=0.
From the graph, the coordinates of the y-intercept is (0, 7)
3. The X-intercept is located at (-3,0)
The x intercept is the point where the graph meets the x-axis, that is, the value of x on the graph when y=0.
From the graph the curve x axis at x= 1.5 and x= 4.5
So, the x-intercept is truly located at (1.5, 0) and (4.5,0)

Answer:
a) [tex]( -[/tex]∞[tex], -\frac{4}{3}[/tex][tex])[/tex] ∪ [tex](-\frac{4}{3}[/tex] , ∞[tex])[/tex]
b) [tex][-\frac{5}{2} ,[/tex] ∞)
Step-by-step explanation:
The domain of a function is known as the input. We need to find whatever set of numbers can be plugged into every x of a function so that the result is a real number.
a) This problem is a fraction alone, so we need to find out what input of x will make the denominator zero - that will be the number we "skip" when writing out the domain. This is because if the denominator were zero, then it would be 1 divided by 0, which would be undefined and therefore not a real number.
To find this number, we can just take the denominator and solve for x:
[tex]3x + 4 = 0[/tex]
[tex]3x = -4\\x = -\frac{4}{3}[/tex]
Therefore [tex](-[/tex]∞, [tex]-\frac{4}{3}[/tex]) ∪ [tex](-\frac{4}{3},[/tex] ∞[tex])[/tex] is our answer.
b) This problem is just a square root alone, so we need to find out what input of x will make the number inside the square root negative - that number, and the numbers less than it, will be the numbers that we "skip." This is because if the number inside the square root was negative, then it would produce an imaginary answer and not a real one.
A simple trick to find the domain would be to set the terms inside the square root greater than or equal to 0 then solve for x:
[tex]2x + 5\geq 0 \\2x \geq -5\\\\x \geq \frac{-5}{2}[/tex]
Thus, the domain would be any number greater than or equal to [tex]-\frac{5}{2}[/tex], which in interval notation would be written [tex][-\frac{5}{2} ,[/tex] ∞).

Iced tea and lemonade sell for different prices per gallon at Chicken-Fill-Up. Two gallons of iced tea and 3 gallons of lemonade cost a total of $23.25. Five gallons of iced tea and 4 gallons of lemonade cost a total of $41.50. What is the price per gallon for each drink at Chicken-Fill-Up?
Answer:
the price per gallon for each drink is $4.5 and $4.75 respectively
Step-by-step explanation:
The computation of the price per gallon for each drink is as follows;
Let us assume the ice tea be x
And, lemonade be y
So the equations are
2x + 3y = $23.25 .......(i)
5x + 4y = $41.50 ................(ii)
Now multiplied by 5 and 2 in equation 1 and 2
10x + 15y = $116.25
10x + 8y = $83
7y = 33.25
y = $4.75
Now put the y value in any of the equation
2x + 3($4.75) = $23.25
x = $4.5
So, the price per gallon for each drink is $4.5 and $4.75 respectively
