What is the range of the function g(x) = 3x2 - 6x + 3 when the domain is defined as the set of integers, x, such that 0<=x<=4? Show all work. I really need help y’all I have and f :(
Answers
Answer:
the domain of this function is [0, 27]
Step-by-step explanation:
One way of answering this question would be to make a table of x and y values. Your x-values would be [0, 4] (that is, all x values between 0 and 4, including end points.
x y = 3x² - 6x + 3
0 3
1 0
2 3
4 27
From this table, it appears highly likely that the smallest y value would be 0, at x = 1, and that the largest would be 27 at x = 4. Thus, the domain of this function is [0, 27].

Aunt Gwen is pricing cakes for a baby shower she is throwing. She wants one large cake shaped like a duckling and also some cupcakes in pastel colors. Hillsboro Bakery charges $4 for each cupcake, plus $28 for the large cake. Carson's Sweet Shoppe charges $55 for the large cake and $1 for each cupcake. If Aunt Gwen orders a certain number of cupcakes, the cost will be the same at either bakery. How many cupcakes would that include? What would the total cost be?
If Aunt Gwen orders ___ cupcakes, it will cost $ ___ at either shop.
Answers
Answer:
9 cupcakes and 64$
Step-by-step explanation:
try the math
So first, set up an equation for each shop, for the first one you can write 4x+28 (since it is 4 dollars for each cupcake and 28 dollars for the cake) and for the second shop you can write 55+x ( 55 dollars for cake and a dollar for each cupcake.) now you can set the 2 equations equal to each other because they want the number for cupcakes where the price will be equal. So 4x+28=55+x and then solve. I don’t want to completely tell you the answer but if you are stuck, you can tell me and I will gladly help.
The following set of coordinates represent which figure?(7,10) (4,7) (6,5) (9,8)
Answers
Answer: i think a diamond
Step-by-step explanation:
Let's assume these are the vertices in order and calculated the squared lengths of the sides. Let's calculate the vector for each side, which is the difference of the endpoints:
(7,10) - (4,7) = (3, 3)
(4,7) - (6,5) =(-2, 2)
(6,5) - (9,8) = (-3, -3)
(9,8) - (7,10) = (2, -2)
We see the pattern: (3,3) = -(-3,-3) and (-2,2) = -(2,-2)
We have two pairs of opposite vectors so we have a parallelogram.
Let's check the dot product of adjacent sides:
(3,3) . (-2, 2) = 3(-2) + 3(2) = 0
Zero dot product, we have perpendicularity. A parallelogram with one right angle is a

Simplify 8r+(-4r)+3 and then solve if r=5
Answers
Simplify= 4r+3
Because 8r plus -4r which is 4r and then 3 can’t be simplified so u keep it the same
Then the answer if r=5 is 23
Because the equation looks like 4(5)+3
5 times 4 is 20 plus 3 is 23
Final answer:
The expression 8r+(-4r)+3 simplifies to 4r + 3. Substituting r=5 into the simplified expression gives you 4(5) + 3, which equals 23.
Explanation:
To simplify the expression 8r+(-4r)+3, you combine the like terms which are 8r and -4r. They are like terms because they both contain the variable r.
Simplifying the like terms:
8r + (-4r) = 8r - 4r = 4r
So now the expression simplifies to 4r + 3. To solve for r = 5, you substitute the value of r into the simplified expression:
4r + 3 becomes 4(5) + 3,
20 + 3 = 23.
Therefore, when r = 5, the simplified expression evaluates to 23.

Answers
For this you have to make two proportions that are [tex]\frac{part}{whole}[/tex] and set them equal to each other.
The first proportion represents the percent of people who like silver as their favorite car color
Since this is a circle graph the whole will always be 100 because percents are always taken out of 100
The part would be 10 because only 10% out of the 100% like silver
The second proportion is the people that represent the response.
350 would be the whole because that is the total amount of people surveyed
The part is unknown and what you are solving for.
Here is how the proportion should look like:
[tex]\frac{10}{100} = \frac{x}{350}[/tex]
Cross multiply (If you don't know what this is look at the image below to see my work)
The cross multiplication will give you:
3500 = 100x
Isolate x by dividing 100 to both sides
3500/100 = 100x/100
35 = x
This means that 35 people out of the 350 surveyed like silver cars

given the functiom y=x^4 -8x^2+16. on which intervals is the function increasing
Answers
Answer:
[tex]x\in (-2,0)\cup (2,\infty)[/tex]
Step-by-step explanation:
Find the derivative of the function [tex]y=x^4 -8x^2 +16:[/tex]
[tex]y'=4x^3 -8\cdot 2x\\ \\y'=4x^3 -16x[/tex]
The function is increasing when [tex]y'>0,[/tex] so solve the inequality
[tex]4x^3-16x>0\\ \\4x(x^2-4)>0\\ \\4x(x-2)(x+2)>0\\ \\x\in (-2,0)\cup (2,\infty)[/tex]
You can see from the graph that the function increases for [tex]x\in (-2,0)\cup (2,\infty)[/tex]
Final answer:
To determine the intervals where the function y = x⁴ - 8x² + 16 is increasing, calculate the first derivative, find its critical points, and analyze the sign changes. The function is increasing on the intervals (-∞, -2), (0, 2), and (2, ∞).
Explanation:
Intervals Where the Function is Increasing
To determine on which intervals the function y = x⁴ - 8x² + 16 is increasing, we need to analyze the function's first derivative. The first derivative, y', indicates the slope of the tangent to the function at any point. When y' > 0, the function is increasing. Let's find the first derivative of the given function:
Take the derivative of the function y with respect to x: y' = 4x³ - 16x.
Set the derivative equal to zero to find critical points: 4x³ - 16x = 0.
Factor out the common term (4x): 4x(x² - 4) = 4x(x + 2)(x - 2) = 0.
Solve for x to find critical points: x = 0, x = -2, and x = 2.
Analyze the sign of y' around these points to determine where the function is increasing and decreasing.
Through analyzing the signs, you will find that the function is increasing on the intervals (-∞, -2), (0, 2), and (2, ∞).
Note that these intervals are determined by looking at the sign changes of the first derivative around the critical points and selecting the intervals where the derivative is positive.

Answer:
AREA:

CIRCUMFERENCE:

Step-by-step explanation:
The formula that is used to calculate the area of a circle is:
[tex]A=\pi r^2[/tex]
Where "r" is the radius of the circle.
The formula for calculate the circumference of a circle is:
[tex]C=2\pi r[/tex]
Where "r" is the radius of the circle.
Then, you need to find the radius. This is:
[tex]r=\frac{16.6m}{2}=8.3m[/tex]
Substituting the radius, you get that the area and the circumference are:
AREA:
[tex]A=\pi (8.3m)^2=216.42m^2[/tex]
CIRCUMFERENCE:
[tex]C=2\pi (8.3m)=52.15m[/tex]
Answer with step-by-step explanation:
We are given a circle which is divided into two halves and has a diameter of 16.6 meter. We are to find the area and circumference of the circle to the right.
It means that our radius will be the half of the given diameter.
Radius = 16.6/2 = 8.3 m
Area = [tex]\pi r^2[/tex] = [tex]\frac{\pi \times (8.3)^2}{2}[/tex] = 216.4 m^2
Circumference = [tex]2 \pi r[/tex] = [tex]2 \times \pi \times 8.3[/tex] = 52.2 m

Answers
Final answer:
The surface area of the rectangular prism is 376 square inches.
Explanation:
To find the surface area of an object, we need to calculate the sum of the areas of all its faces. Given the dimensions 10 in., 6 in., 8 in., and 7 in., we can assume that these are the lengths of the sides of a rectangular prism. The formula to find the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively.
Using the given values, we can substitute 10 in. for l, 6 in. for w, and 8 in. for h to find the surface area:
Surface Area = 2(10 in.)(6 in.) + 2(10 in.)(8 in.) + 2(6 in.)(8 in.)
Surface Area = 120 in² + 160 in² + 96 in²
Surface Area = 376 in²
