What is the intermediate step in the form (x + a)2 = b as a result of completing the square for the following equation? x² + 4x = 12
The equation in the form (x + a)² = b is (x + 2)² = 16
How to determine the intermediate step?The equation is given as:
x² + 4x = 12
Take the coefficient of x
k = 4
Divide by 2
k/2 = 2
Square both sides
(k/2)² = 4
Add this result to both sides of x² + 4x = 12
x² + 4x + 4 = 12 + 4
Evaluate the sum
x² + 4x + 4 = 16
Express as a perfect square
(x + 2)² = 16
Hence, the equation in the form (x + a)² = b is (x + 2)² = 16

Given the function f(x) = 2(3)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.
Part A: Find the average rate of change of each section.
Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other.
Answer:
Given function:
[tex]f(x)=2(3)^x[/tex]
Part AThe average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
[tex]\begin{aligned}\textsf{Average rate of change - Section A} & =\dfrac{f(1)-f(0)}{1-0}\\\\& =\dfrac{2(3)^1-2(3)^0}{1-0}\\\\& =\dfrac{6-2}{1}\\\\& =4 \end{aligned}[/tex]
[tex]\begin{aligned}\textsf{Average rate of change - Section B} & =\dfrac{f(3)-f(2)}{3-2}\\\\& =\dfrac{2(3)^3-2(3)^2}{3-2}\\\\& =\dfrac{54-18}{1}\\\\& =36 \end{aligned}[/tex]
Part B[tex]\dfrac{\textsf{Average rate of change of Section B}}{\textsf{Average rate of change of Section A}}=\dfrac{36}{4}=9[/tex]
Therefore, the average rate of change of Section B is 9 times greater than Section A.
The function is an exponential function (with 3 as the growth factor) so the rate of change increases over time.
Solve the equation
3(2x + 2) = 3x - 15
A. X = -7
B. X = -17/3
C. X = 3
D. X = 7
When starting a problem, almost every single problem needs to be understood by the person answering so they can see what needs to be done. In this example, we are given an expression and told to solve the equation which means that we need to solve for the unknown, in this case x.
Now that we know what we must do, we can start to solve the problem. Looking at the problem we can see that the step that we must take is to distribute 3 into the parenthesis.
Distribute
[tex]3(2x + 2) = 3x - 15[/tex][tex](3*2x) +(3* 2) = 3x - 15[/tex][tex](6x) +(6) = 3x - 15[/tex][tex]6x+6 = 3x - 15[/tex]Now that we distributed the values inside of the parenthesis we can move onto the next step which is to help isolate x. What we should do is subtract 6 from both sides which will help leave x with its coefficient alone.
Subtract 6 from both sides
[tex]6x+(6 - 6 )= 3x +(- 15 - 6)[/tex][tex]6x= 3x +(- 15 - 6)[/tex][tex]6x= 3x - 21[/tex]The next step that we should take to help solve for the unknown is to subtract 3x from both sides.
Subtract 3x from both sides
[tex](6x - 3x)= (3x - 3x) - 21[/tex][tex](6x - 3x)= - 21[/tex][tex]3x = - 21[/tex]The final step that we must take to help isolate the unknown would be to divide both sides by 3. This would remove the coefficient from x and we would get -21 divided by 3.
Divide both sides by 3
[tex]\frac{3x}{3} = \frac{- 21}{3}[/tex][tex]x = \frac{- 21}{3}[/tex][tex]x = -7[/tex]Therefore, after simplifying the expression that was given to solve for the unknown we were able to determine that the option that would best match the solution is option A, x = -7.
Answer:
a) x = -7
Step-by-step explanation:
Given: 3(2x + 2) = 3x - 15
1. Distribute:
3(2x) + 3(2) = 3x - 15
⟹ 6x + 6 = 3x - 15
2. Subtract 3x from both sides:
6x - 3x + 6 = 3x - 3x - 15
⟹ 3x + 6 = -15
3. Subtract 6 from both sides:
3x + 6 - 6 = -15 - 6
⟹ 3x = -21
4. Divide both sides by 3:
3x ÷ 3 = -21 ÷ 3
⟹ x = -7
5. Check your work:
3(2x + 2) = 3x - 15
3(2(-7) + 2) = 3(-7) - 15
3(-14 + 2) = -21 - 15
3(-12) = -21 - 15
⟹ -36 = -36 ✔

f(x)= |x|-5
A vertical shift of 4 up.
A horizontal shift of 4 to the right.
A vertical shift of 5 down.
A horizontal shift of 4 to the left.
Question 4
Answer: Choice B
A horizontal shift of 4 to the right.
========================================================
Reason:
Replacing x with x-4 basically means we're decreasing each input by 4 units.
What this does is move the xy axis 4 units to the left. If we held the function curve fixed in place as the xy axis moved like this, then it would give the illusion the function is moving 4 units to the right.

28. sylvia researched changes in the deer population in her state's parks during her lifetime

she wrote the equation 4800(8) { = 600 and plans to solve fort to determine in how
many years it will take for the current population of 4800 deer to reduce to 600.
Using an exponential function, it is found that it will take 24 years for the current population of 4800 deer to reduce to 600.
What is an exponential function?An exponential function is modeled by:
[tex]y = ab^x[/tex]
In which:
a is the initial value.b is the rate of change, as a decimal.In this problem, considering the initial value of 4800, and that the population halves every 8 years, the equation is given by:
[tex]A(t) = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}[/tex]
The population will be of 600 when A(t) = 600, hence:
[tex]A(t) = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}[/tex]
[tex]600 = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}[/tex]
[tex]\left(\frac{1}{2}\right)^{\frac{t}{8}} = \frac{600}{4800}[/tex]
[tex]\left(\frac{1}{2}\right)^{\frac{t}{8}} = \frac{1}{8}[/tex]
[tex]\left(\frac{1}{2}\right)^{\frac{t}{8}} = \left(\frac{1}{2}\right)^3[/tex]
Hence:
t/8 = 3.
t = 24.
It will take 24 years for the current population of 4800 deer to reduce to 600.

Compare the equations represented in the table, equation, and graph over
the interval
[-5, 3]. Which function is increasing the fastest?
Answer:
Tabled Function
Step-by-step explanation:
To determine which function is increasing the fastest over the interval [-5, 3], we need to calculate and compare each function's average rate of change over the given interval.
The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Given interval: -5 ≤ x ≤ 3
Therefore, a = -5 and b = 3
Tabled function[tex]f(3)=7[/tex]
[tex]f(-5)=-17[/tex]
[tex]\implies \textsf{Average rate of change}=\dfrac{f(3)-f(-5)}{3-(-5)}=\dfrac{7-(-17)}{3+5}=3[/tex]
Equation: y = x² - 2[tex]f(3)=(3)^2-2=7[/tex]
[tex]f(-5)=(-5)^2-2=23[/tex]
[tex]\implies \textsf{Average rate of change}=\dfrac{f(3)-f(-5)}{3-(-5)}=\dfrac{7-23}{3-(-5)}=-2[/tex]
Graphed functionFrom inspection of the graph:
[tex]f(3)\approx8[/tex]
[tex]f(-5) \approx 0[/tex]
[tex]\implies \textsf{Average rate of change}=\dfrac{f(3)-f(-5)}{3-(-5)} \approx \dfrac{8-0}{3-(-5)}=1[/tex]
Therefore, the Tabled Function has the greatest average rate of change in the interval [-5, 3] and so it is increasing the fastest.

How to calculate the maximum height of an object?The maximum height of an object the point where the velocity of the object is zero.
Given the function that represents the height of the airplane is expressed as h(t) = -(t-10)² + 95
The maximum height is the point where h'(t) = 0
h'(t) = -2(t-10)
0 = -2t + 10
2t = 10
t = 5secs
Substitute t =10 into the function
h(5) = -(10-10)² + 95
