Find all the zeroes of the polynomial function
[tex]f(x)=x^3 -5x^2+6x -30.[/tex] If you use synthetic division, show all three lines of numbers.
Answer:
(x -5)(x² + 6)
Step-by-step explanation:
f(x) = x³ - 5x² + 6x - 30
Synthetic division:
5 1 -5 6 -30
0 5 0 30
1 0 6 0
(x - 5) is a factor
f(x) = x³ - 5x² + 6x - 30 = (x -5)(x² + 6)

Work out 252% of 120.
Answer:
302.4
Step-by-step explanation:
252% × 120 =
(252 ÷ 100) × 120 =
(252 × 120) ÷ 100 =
30,240 ÷ 100 =
302.4
Answer: 302.4
Step-by-step explanation:
Write 252% as
252/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
252/100 of 120 = 252/100 x 120 =
Therefore, the answer is 302.4

At the beginning of the day the stock market points and stays at this level for most of the day. At the end of the day the stock market points from the at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Incomplete question. Here's the full question:
At the beginning of the day, the stock market goes up 30 1/2 points. At the end of the day, the stock market goes down 120 1/4 points. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
-15%
Step-by-step explanation:
First, we convert the fraction to a whole number;
At the beginning of the day: [tex]30\frac{1}{2}[/tex] = 15 (30*1 / 2)
At the end of the day: [tex]120\frac{1}{4}[/tex] = 30 (120 * 1 / 4)
Next, since we are told that at the end of the day, the stock market goes down, it means we will subtract any gain it had by the change;
[tex]15-30 = -15%[/tex]%
Hence, the total change in the stock market from the beginning of the day to the end of the day is -15%.

The exterior angle measure of a regular polygon Is 20 degrees. How many sides does the polygon have?
A. 20
B.18
C.9
D.16
Answer:
18 sides
Step-by-step explanation:
Exterior angle = 360° ÷ n
20° = 360°/n
n× 20 = 360/n ×n
20n = 360
n= 360/20
n = 18

Tracy wants to make 4 curtains. Each requires 54 yards of fabric. How
much fabric does she need?
Pls helpppp!!!!
Answer:
21 yards
Step-by-step explanation:
4*21/4
84/4
21
Answer:
21yards multiplication
Step-by-step explanation:
Given parameters:
Number of curtains = 4
Amount of fabric needed = [tex]5\frac{1}{4}[/tex]yards
Unknown:
How much of fabric is needed = ?
Solution:
A curtain requires [tex]5\frac{1}{4}[/tex]yards = [tex]\frac{21}{4}[/tex]yards
Now to make 4 curtains, we would need [tex]\frac{21}{4}[/tex] x 4 = 21yards.
Adult visitors to an amusement park pay $40 for admission, while children are charged $25. Yesterday, a total of 625 people visited the park paying a total of $19,000 for admission. Drag and drop numbers in the boxes to create an equation that models this situation if x = the number of adult admission tickets sold and y = the number of child admission tickets sold yesterday. 25, 30, 35, 40, 45 ____x+____y = 19,000
Answer:
[tex]40x+25y=19,000[/tex]
Step-by-step explanation:
[tex]x[/tex] denotes the number of adult admission tickets sold and [tex]y[/tex] denotes the number of child admission tickets sold.
Cost of an adult admission ticket = $40
Cost of [tex]x[/tex] adult admission tickets = $40[tex]x[/tex]
Cost of a child admission ticket = $25
Cost of [tex]y[/tex] child admission tickets = $25[tex]y[/tex]
Total amount paid by 625 people = $19,000
So,
[tex]40x+25y=19,000[/tex]

41.25 because you divide the cost into the profit and that equals 41.25
Answer:
$41.25
Step-by-step explanation:
recall that the formula for percent markup is
% Markup = [ (price - cost) / cost ] x 100% (also see attached for reference)
we are given:
% Markup = 65%
Cost = $25
Simply substitute the known values into the formula above
% Markup = [ (price - cost) / cost ] x 100%
65 = [ (price - 25) / 25] x 100
65/100 = (price - 25) / 25
0.65 = (price - 25 ) / 25
0.65 (25) = price - 25
price - 25 = 16.25
price = 25 + 16.25
price = $41.25
What the solution for x is in 14+x=3a+ab?
Answer: a= x+14 /b+3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Simplifying
14 + x = 3a + ab
Solving
14 + x = 3a + ab
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14' to each side of the equation.
14 + -14 + x = 3a + -14 + ab
Combine like terms: 14 + -14 = 0
0 + x = 3a + -14 + ab
x = 3a + -14 + ab
Reorder the terms:
x = -14 + 3a + ab
Simplifying
x = -14 + 3a + ab

which form most quickly reveals the vertex?
choose 1 answer:
a. g(x)=-2x^2-16x-14
b. g(x)=-2(x+4)^2+18
c. g(x)=-2(x+1)(x+7)
what is the vertex?
vertext= (___,___)
Answer:
The most quickly reveals the vertex is g(x) = -2(x + 4)² + 18 ⇒ b
The vertex = (-4, 18)
Step-by-step explanation:
The vertex form of the quadratic function f(x) is:
f(x) = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of the vertex pointThe most quickly reveals to find the vertex is the vertex form above
Look at the answer and try to find a similar form to the vertex form above
∵ g(x) = -2(x + 4)² + 18
∴ a = -2
∴ h = -4
∴ k = 18
⇒ That means this form is similar to the form above
∴ The most quickly reveals the vertex is g(x) = -2(x + 4)² + 18
∴ The vertex = (-4, 18)

Tyler bought a jacket regularly priced $35.00.
With a 30% markdown and a sales tax of 6%, approximately what is the cost of Tyler's jacket?
Answer:
$25.97
Step-by-step explanation:
You want to find 70% of $35.00 because there is a 30% markdown meaning 70% of the original price. 70% is the same as 7/10.
to get the price after markdown multiply $35.00 by 7/10 which equals $24.5
Multiply $24.5 by .06 to get the sales tax which is $1.47
So the sales tax is $1.47 and the price after markdown is $24.5 so take the sum of both. $1.47 + $24.5 = $25.97
The cost of Tyler's jacket is $23.03.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Tyler bought a jacket regularly priced $35.00.
With a 30% markdown, the cost of jacket is
30% of 35
= 30/100 ×35
= 0.3×35
= 10.5
So, the cost of jacket is 35-10.5=$24.5
Now, sales tax on $24.5
That is, 6% of $24.5
= 6/100 ×24.5
= 0.06×24.5
= 1.47
Cost of jacket is 24.5-1.47
= $23.03
Therefore, the cost of Tyler's jacket is $23.03.

This diagram of a rectangular city park was drawn using a scale of 1 centimeter to 20 meters
(In the diagram shown, assume each square on the grid is 1 centimeter in length.)
What is the area, in square meters, of the actual park?
What is the scale factor?
Answer:
Scale factor for the drawing from actual park = [tex]\frac{1}{20}[/tex]
Area of the actual park = 1200 cm²
Step-by-step explanation:
Length of the rectangular city park = 5 cm
Width of the rectangular park = 6 cm
Using scale factor 1 cm = 20 meters
Scale factor = [tex]\frac{\text{length of the park in drawing}}{\text{Actual length of park}}=\frac{1}{20}[/tex]
[tex]\frac{5}{\text{Actual length of park}}=\frac{1}{20}[/tex]
Actual length = 5 × 20 = 100 meters
Actual width = 6 × 20 = 120 meters
Area of the rectangular park = length × width
= 100 × 120
= 1200 square meters
Therefore, Scale factor from actual length to the length in drawing = 1 : 20
Area of the rectangular park = 1200 square feet
