write 7x^2-4+6x^3-4x-x^4 in standard form
Answer:
8+24x^8
Step-by-step explanation:
Final answer:
The polynomial in standard form is –x⁴ + 6x³ + 7x² – 4x – 4, with terms ordered from the highest degree to the lowest degree.
Explanation:
To write the polynomial 7x²-4+6x³-4x-x⁴ in standard form, we need to arrange the terms in descending order of their exponents. The standard form for a polynomial is to start with the highest degree term and go down to the constant term.
So, the polynomial in standard form will be:
-x⁴ + 6x³ + 7x² - 4x - 4.
This polynomial is now in the proper order and ready to be used for further algebraic operations such as factoring or solving for specific values of x.

Find the volume. *
6) radius = 16 in; height = 27 in
Volume =
The volume of the cylinder is approximately 21727.938in^3.
The volume (V) of a cylinder is calculated using the formula:
V=πr^2 h
where:
π (pi) is a mathematical constant approximately equal to 3.14159,
r is the radius of the cylinder,
h is the height of the cylinder.
Given that the radius (r) is 16 inches and the height (h) is 27 inches, you can substitute these values into the formula:
V=π×(16in)^2 ×27in
Now, let's calculate the volume. Remember to use the value π as approximately 3.14159:
V≈3.14159×256×27
V≈3.14159×6912
V≈21727.938in^3
So, the volume of the cylinder is approximately 21727.938in^3.
What is the domain of y = log Subscript 4 Baseline (x + 3)?
all real numbers less than –3
all real numbers greater than –3
all real numbers less than 3
all real numbers greater than 3
Answer:
All real numbers greater than -3
Step-by-step explanation:
The domain of a log is the baseline is greater than 0.
Set x + 3 greater than zero and solve
x + 3 > 0
x > -3
The domain of the function y = log4(x + 3) is all real numbers greater than -3, as the argument of the logarithm must be positive.
The domain of the function y = log4(x + 3) is determined by the values of x for which the logarithmic expression is defined. Since the logarithm of a number is only defined for positive arguments, we need x + 3 to be greater than zero. Therefore, the domain is all real numbers greater than -3.
What this means is x must be any number such that when you add 3 to it, the result is a positive number. A simple inequality expresses this: x + 3 > 0, which simplifies to x > -3. Hence, the correct domain is all real numbers greater than -3.

Step-by-step explanation:
Your question is a bit unclear, so I'm going to assume you want the value of y or x:
(y+3)^2=-12(x-2)
-(y+3)^2/12=x-2
-(y+3)^2/12+2=x
(y+3)^2=-12(x-2)
y+3=sqrt(-12x+24)
y=sqrt(-12x+24)-3
Angle DXC and ________ are complementary angle?
Angle DXC and BXC are complementary angle.
Step-by-step explanation:
∠DXC complements with ∠BXC
Complementary angle means the sum of 2 angles that have a vein or form a right angle, which is 90°.
If we add ∠DXC with ∠BXC, it will form a right angle, 90°.
Hope it helpful and useful :)
We want to find the complementary angle to DXC.
We will see that the complementary angle is CXB
Let's start by defining what complementary angles are.
Two angles a and b are complementary if:
a + b = 90°.
This means that we must find another angle such that when we add it to DXC we get a right angle.
Let's look at the diagram.
We can see that we have the line AD, and there is a segment XB, such that the angle AXB is a right angle.
Then the angle DXB is also a right angle.
Now, you can see that the angle DXB is equivalent to DXC + CXB
Then we can see that the complementary angle to DXC is CXB.

When the outliers are removed, how does the mean change? (2 points) dot plot with 1 on 50, 1 on 76, 1 on 78, 2 on 79, 1 on 80, 1 on 81, 2 on 82, 1 on 83
Answer:
Answer: The mean increases by 3
Step-by-step explanation:
The original data set is
{50, 76, 78, 79, 79, 80, 81, 82, 82, 83}
The outlier is 50 because it is not near the group of values from 76 to 83 which is where the main cluster is.
The original mean is M = (50+76+78+79+79+80+81+82+82+83)/10 = 77
If we take out the outlier 50, the new mean is N = (76+78+79+79+80+81+82+82+83)/9 = 80
So in summary so far
old mean = M = 77
new mean = N = 80
The difference in values is N-M = 80-77 = 3
So that's why the mean increases by 3
Answer:
The mean increases by 3 would be the correct answer

A 50 lb bag of flour costs $27. How much does 8 lbs of flour cost? Use a proportion to solve.
Answer:
$4.32
Step-by-step explanation:
We want to write a proportion to solve
50 lbs 8 lbs
----------- = --------- -----
27 dollars x dollars
Using cross products
50x = 8*27
50x=216
Divide each side by 50
50x/50 = 216/50
x=4.32
Answer:
$4.32
Step-by-step explanation:
Make a proportion using this setup:
pounds/cost=pounds/cost
A 50 pound bag costs $27, and a 8 pound bag costs $x
50 lb/$27=8 lb/$x
50/27=8/x
Cross multiply
50*x=27*8
50x=216
We want to find what a 8 pound bag, will cost (x). To do this, we need to get x by itself.
Since x and 50 are being multiplied, divide both sides by 50
50x/50=216/50
x=216/50
x=4.32
A 8 pound bag of flour will cost $4.32
Find the volume of the triangular prism 3cm 4 cm 5cm 11cm
To find the volume of a triangular prism, multiply the base area by the height. The formula for the volume of a prism is V = base area x height. In this case, the base is a triangle, so calculate the area using the formula for the area of a triangle. Substitute the values and multiply the base area by the height to find the volume.
Explanation:To find the volume of a triangular prism, we need to multiply the base area by the height. The formula for the volume of a prism is:
V = base area x height
In this case, the base of the prism is a triangle, so we calculate the area using the formula for the area of a triangle:
area = (base x height) / 2
Substituting the given measurements, we have:
base = 3 cm, height = 4 cm, height of prism = 11 cm
First, find the area of the triangle: area = (3 cm x 4 cm) / 2 = 6 cm².
Then, multiply the base area by the height of the prism: volume = 6 cm² x 11 cm = 66 cm³.
The dimensions of Kara’s bedroom floor are 8 3/4 feet by 10 2/3. What if the area of her bedroom floor
Answer:
[tex]93\frac{1}{3}[/tex]
Step-by-step explanation:
The area of a bedroom floor is the width multiplied by the length. We know that the length's is [tex]10\frac{2}{3}[/tex] feet and the width is [tex]8\frac{3}{4}[/tex] feet. We just multiply the 2 fractions to find the area of her bedroom floor in feet squared
[tex]10\frac{2}{3} * 8\frac{3}{4}[/tex]
→ There area various methods but I am going to use the improper fraction method. First convert the fractions into improper fractions
[tex]\frac{32}{3} *\frac{35}{4}[/tex]
→ We can cancel out 4 and 32 with 1 and 8
[tex]\frac{8}{3} *\frac{35}{1}[/tex]
→ Multiply like normal fractions
[tex]\frac{280}{3}[/tex]
→ Convert into mixed fraction
[tex]93\frac{1}{3}[/tex]
Final answer:
The area of Kara's bedroom floor is 93 1/3 square feet, which is calculated by converting the given dimensions into improper fractions, multiplying them, and then simplifying.
Explanation:
The area of Kara's bedroom floor is calculated by multiplying the room's length by its width. The dimensions of the room are given as 8 3/4 feet by 10 2/3 feet. We first convert these mixed numbers into improper fractions: 8 3/4 becomes 35/4 and 10 2/3 becomes 32/3. To find the area, we multiply these two fractions together:
Area = (35/4) × (32/3) feet2
Now, we find the product of the two fractions:
Area = (35 × 32) / (4 × 3) square feet
Area = 1120 / 12 square feet
Area = 93 1/3 square feet
Therefore, the area of the bedroom floor is 93 1/3 square feet. When purchasing carpet, Kara would need to round up to ensure she has enough carpet to cover the entire floor, which is typically sold by the whole square foot.

A line, y = mx + b, passes through the point (10, 3) and is parallel to the line 2x+5y=12.
What is the y-intercept
We have been given that a line [tex]y=mx+b[/tex] passes through the point (10, 3) and is parallel to the line [tex]2x+5y=12[/tex]. We are asked to find the y-intercept of the line.
First of all we will rewrite our given equation in slope-intercept form as:
[tex]2x-2x+5y=12-2x[/tex]
[tex]5y=-2x+12[/tex]
[tex]\frac{5y}{5}=-\frac{2}{5}x+\frac{12}{5}[/tex]
[tex]y=-\frac{2}{5}x+\frac{12}{5}[/tex]
We know that slope of parallel lines is equal, so slope of parallel line to our given line would be [tex]-\frac{2}{5}[/tex].
Now we will use slope-intercept form of equation to find y-intercept.
[tex]y=mx+b[/tex], where,
m = Slope,
b = The y-intercept.
Let us substitute [tex]m=-\frac{2}{5}[/tex] and coordinates of point [tex](10,3)[/tex] in above equation as:
[tex]3=-\frac{2}{5}(10)+b[/tex]
[tex]3=-2(2)+b[/tex]
[tex]3=-4+b[/tex]
[tex]3+4=-4+4+b[/tex]
[tex]7=b[/tex]
Therefore, the y-intercept is 7 and our required equation would be [tex]y=-\frac{2}{5}x+7[/tex].

A jar contains 5 red, 4 blue, and 3 yellow marbles. What is the probability of pulling a red marble, then pulling a blue marble, without replacement? Calculate to the nearest tenth.
Final answer:
The probability of pulling a red marble, then pulling a blue marble without replacement is approximately 0.114.
Explanation:
To calculate the probability of pulling a red marble, then pulling a blue marble without replacement, we need to determine the number of favorable outcomes and the total number of possible outcomes.
The number of red marbles is 5, and the number of blue marbles is 4. When the first marble is pulled, there are a total of 12 marbles. So, the probability of pulling a red marble on the first draw is 5/12.
After pulling out a red marble, the number of blue marbles becomes 3. So, the probability of pulling a blue marble on the second draw is 3/11.
To calculate the overall probability, we multiply the probabilities of each event:
P(Red and then Blue) = P(Red) × P(Blue | Red) = 5/12 × 3/11 ≈ 0.114
Final answer:
The probability of drawing a yellow marble and then a green marble without replacement is 0.1.
Explanation:
The probability of drawing a yellow marble and then a green marble without replacement is calculated as follows:
Calculate the probability of drawing a yellow marble first: 2/9 (2 yellow marbles out of a total of 9 marbles).
Now, after drawing a yellow marble, there are 8 marbles left. Calculate the probability of drawing a green marble next: 4/8 (4 green marbles out of the remaining 8).
Multiply the two probabilities: (2/9) * (4/8) = 1/9 = 0.1111 (rounded to the nearest tenth).

An animal shelter houses cats, rabbits, and ferrets. There are 108 animals at the shelter. Of the animals, one third are cats. Three fourths of the remaining animals are rabbits. How many of the animals are ferrets?
Answer:
18 ferrets
Step-by-step explanation:
From the statement you can write the following:
c+r+f= 108
c=cats
r= rabbits
f= ferrets
Then, you have that one third of the animals are cats:
c= 108*(1/3)= 36
Next, three fourths of the remaining animals are rabbits:
r= (108-36)*(3/4)= 72*(3/4)= 54
Now, as you have determine the amount of cats and rabbits, you can isolate f and find the amount of ferrets:
f=108-c-r
f=108-36-54
f= 18
According to this, the answer is that there are 18 ferrets.
