Three functions are given below: f(x), g(x), and h(x). Find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest). Show your work for OR explain how you found each axis of symmetry.
f(x) = -4(x − 8)2 + 3
g(x) = 2x2 − 16x + 15
h(x)= the picture
Answer:
Step-by-step explanation:
f(x)=-4(x-2)²+3
put x-2=0
axis of symmetry is x=2
g(x)=-2(x²+8x)+15
=-2(x²+8x+4²-4²)+15
=-2(x+4)²+32+15
=-2(x+4)²+47
put x+4=0
axis of symmetry is x=-4
h(x) is minimum at x=1
axis of symmetry is x=1

-8x is less than or equal to 32
What is the inequalities that are possible.
Answer:
We conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.
Step-by-step explanation:
Given the inequality
[tex]-8x\:\le 32[/tex]
Solving the inequality
[tex]-8x\:\le 32[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-8x\right)\left(-1\right)\ge \:32\left(-1\right)[/tex]
Simplify
[tex]8x\ge \:-32[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}\ge \frac{-32}{8}[/tex]
Simplify
[tex]x\ge \:-4[/tex]
Therefore, we conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.

A coin is flipped and a number cube is rolled.Use a tree diagram to find the probability of getting heads and a number greater than 2?
For the coin: 2 possibilities, either head or tail. So probability of head is 1/2.
For the cube (assuming numbers are 1 to 6): 6 possibilities (1 2 3 4 5 6). We have 3 odd numbers, so probability of odd number is 3/6=1/2.
You want both head and an odd number, so you multiply the 2 probabilities: 1/2×1/2=1/4.
So the answer is 1/4.
You can use a tree to better understand probabilities.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
2 + 1 = A
On simplifying the equation , we get
A = 3
Now , 3 + 5 = B
B = 8
And , D + 3 = 8
Subtracting 3 on both sides , we get
D = 5
And , 3 + C = 5
Subtracting 3 on both sides , we get
C = 2
Hence , the four digit code is A = 3 , B = 8 , C = 2 , D = 5

. Given that r satisfies the inequality 20.x > 33,
find the smallest value of x if .r is a prime number.
Answer: x = 2.
Step-by-step explanation:
By an online search, i found that the question is:
"Given that x satisfies the inequality 20*x > 33, find the smallest value of x if x is a prime number."
To find the smallest value of x we need to input different possible values of x (where we have the condition that x must be a prime number) and see which one is the first one that makes the inequality true.
The prime numbers are:
2, 3, 5, ....
Let's start with the smaller one, x = 2
So we input it in the inequality and get:
20*2 > 33
40 > 33
this is true.
Then we can have x = 2, which is the smaller prime number that satisfies the inequality.

For a large order, Mr. Magoo made 3/8 kg of fudge in his bakery. He then got 1/6 kg from his sister’s bakery. If he needs a total of 1 1/2 kg, how much more fudge does he need to make? Put your answer in fraction form. Example: Mr. Magoo needs to make #/# more fudge.
(PS: Please show your work)
Answer:
Amount fudge he needs = 23/24 kg
Step-by-step explanation:
Given:
Total fudge wants = 1[tex]\frac{1}{2}[/tex] = 3/2 kg
His sister gave = 1/6 kg
He make = 3/8 kg
Find:
Amount fudge he needs
Computation:
Amount fudge he needs = Total fudge wants - His sister gave - He make
Amount fudge he needs = 3/2 - 1/6 - 3/8
Amount fudge he needs = 23/24 kg

Answer:
I guess the answer is 4.4 cm or 22/5 cm
Step-by-step explanation:
AREA= 15cm^2
Let the Breadth be x
Length= 4x-7
Area = l×b
15 = 4x-7×x
15+7=4x+x
22=5x
22÷5=x
4.4=x

Bradley's Copiers sells and repairs photocopy machines. The manager needs weekly forecasts of service calls so that he can schedule service personnel. Use the actual demand in the first period for the forecast for the first week so error measurement begins in the second week. The manager uses exponential smoothing with a = 0.1. Forecast the number of calls for week 6, which is next week.

The forecast for week 6 is ________ service calls.
Answer:
28.86
Step-by-step explanation:
According to the scenario, computation of given data are as follows,
Exponential smoothing a = 0.1
we can calculate forecast for each week by using following formula,
Forecast for week = Forecast of last week + a × ( actual calls of last week - forecast of last week)
