The graph of f(x) = |x| is vertically stretched by a factor of 3, shifted left 2 units, shifted down 4 units and reflected over the x-axis. What is the function equation of the resulting graph?
Answers
Answer:
The final transformed function becomes:
[tex]f(x)=-3\,|x-2|+4[/tex]
Step-by-step explanation:
The first transformation (vertically stretched by a factor of 3) means we multiply by 3 the original function:
[tex]f(x)= 3\,|x|[/tex]
second transformation (shifted left 2 units) means we add 2 units to "x":
[tex]f(x)=3\,|x+2|[/tex]
third transformation (shifted down 4 units) implies that we subtract 4 units to the full functional expression:
[tex]f(x)=3\,|x+2|-4[/tex]
fourth transformation (reflected over the x-axis) implies that we multiply the full functional expression by "-1":
[tex]f(x)=(-1)\,(3\,|x+2|-4)\\f(x)=-3\,|x-2|+4[/tex]
Step-by-step explanation:
Step 1: Add the vertical stretch
[tex]f(x) = |x|[/tex]
[tex]f(x) = 3|x|[/tex]
Step 2: Shift it to the left 2 units
[tex]f(x) = 3|x|[/tex]
[tex]f(x) = 3|x + 2|[/tex]
Step 3: Shift it down 4 units
[tex]f(x) = 3|x + 2|[/tex]
[tex]f(x) = 3|x + 2| - 4[/tex]
Step 4: Reflect it across the x-axis
[tex]f(x) = 3|x + 2| - 4[/tex]
[tex]f(x) = -3|x + 2| - 4[/tex]
Answer: [tex]f(x) = -3|x + 2| - 4[/tex]

The product of the given expressions will be 84x¹²
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, 4x(-3x⁸)(-7x³) we need to find the product of the same,
So, the product is =
4x(-3x⁸)(-7x³)
= 4x × (-3x⁸) × (-7x³)
= 4 · x · (-3) · x⁸ · (-7) · x³
= 4·21·x⁽¹⁺⁸⁺³⁾

Hannah is designing containers to hold 300 cm3 of juice. Which container is more efficient?

The cylinder has a........A)Smaller surface area B)bigger C)equal

Answers
Answer:
a) 2nd container is more efficient and contains the elements for a container.
b) The cylinder has a........A)Smaller surface area B)bigger C)equal
And will cost.....A)Less to produce B)more C)The same
Step-by-step explanation:
a) The 2nd container has these elements:
Width 20.5cm
Length 6.5cm
side 3.25cm
So, the volume in cubic cm is 20.5 x 6.5 x 3.25 = 433cm3.
This container can hold the 300cm3 of juice.
b) A cylinder is a geometric solid common in everyday life. Examples of a cylinder are soup cans, food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders. The two ends are called bases, and are usually circular. Though, they can take other shapes. When a cylinder is unrolled and flattened out, the side is actually a rectangle.
The surface area of a cylinder is the surface area of each end plus the surface area of the side. The mathematical formula is 2π * r2, where π is the pie and r is the radius of the end and r2 is r squared..

A sector with a radius of 15 cm has a central angle measure of 8pie/5
What is the area of the sector?
Answers
Answer:
The area of the sector is [tex]180\pi \ cm^2[/tex].
Step-by-step explanation:
We have,
Radius of circle is 15 cm
Central angle is [tex]\dfrac{8\pi}{5}\ \text{radian}[/tex]
It is required to find the area of the sector. The formula used to find the area of sector is given by :
[tex]A=\dfrac{1}{2}r^2\theta[/tex]
Plugging all the values in above formula as :
[tex]A=\dfrac{1}{2}\times 15^2\times \dfrac{8\pi}{5}\\A=180\pi \ cm^2[/tex]
So, the area of the sector is [tex]180\pi \ cm^2[/tex].

Marissa jumped 42 times in 7 hours. At that rate, how many times would she jump in 30 minutes?
Answers
Answer:
3
Step-by-step explanation:
Well first let's calculate how many times she jumped per hour. For that we need to divide 42 by 7 which is 6. Now we need to divide that by two because they are asking for every half hour, not every hour. So 6 divided by 2 is 3. So our answer is 3.

Find the sum of the numbers as a product of their GCF is 84 + 108
Answers
Hey there! :)
I believe the correct answer to your question is 12.
Find the prime factorization of 84
84 = 2 × 2 × 3 × 7
Find the prime factorization of 108
108 = 2 × 2 × 3 × 3 × 3
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 2 × 3
GCF = 12

Answer:The area is 14306. 625 cm.
Step-by-step explanation:
To find the area of the circle, we will need to find the diameter and find the radius.
So we know the circumference is 423.9 m and we know to get the circumference, you will need to multiply pie by the diameter .
so now we need divide the circumference by pie to find the diameter.
423.9/ 3.14 = 135 so 135 is the diameter.
To find the radius we need to divide the diameter by 2.
135/2 = 67.5
Now is time to find the area which uses the formula A= nr^2
A = 3.14 * 67.5^2
A = 14306. 625
Write an equation of the line in slope-intercept form. The points are (0,1) and (2,-5)
Answers
Your answer is y = -3x + 1
To find the equation of the line we need both the slope and where it intercepts the y-axis. We are given where it intercepts the y-axis because they tell us it goes through the point (0, 1) and this is a point where x = 0, so it must be on the y-axis.
The equation for finding the slope of a line given two points is [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] where [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are points on the line. Using this, we can substitute in the points we're given and get:
(-5 - 1)/(2 - 0) = -6/2 = -3
Therefore our slope is -3 and our intercept is 1, so the final answer is y = -3x + 1

1) Tanya is buying edging for a triangular flower garden she plans to build in her backyard. If the lengths of the three pieces of edging that she purchases are 13 feet, 10 feet, and 7 feet, will the flower garden be in the shape of a right triangle ?
Answers
Answer:
The Flower Garden is not in the shape of a right Δ
Step-by-step explanation:
~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~
Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;
a^2 + b^2 = c^2,
10^2 + 7^2 = 13^2,
100 + 49 = 169,
149 ≠ 169,
So the Flower Garden will not be in the shape of a right Δ
Use trigonometric functions and/or Pythagorean Theorem to find the missing variable round answer to 2 decimal place (hundredths)
