Which of the following describes the zeroes of the graph of f(x) = –x5 + 9x4 – 18x3?
A. 0 with multiplicity 3, –3 with multiplicity 2, and –2 with multiplicity 1
B. 0 with multiplicity 3, 3 with multiplicity 1, and 6 with multiplicity 1
C. 0 with multiplicity 3, 3 with multiplicity 2, and 2 with multiplicity 1
D. 0 with multiplicity 3, –3 with multiplicity 1, and –6 with multiplicity 1
Answer:
B. 0 with multiplicity 3, 3 with multiplicity 2, and 2 with multiplicity 1
Step-by-step explanation:
Took a test
Factoring and solving the equation, it is found that the zeroes are:
B. 0 with multiplicity 3, 3 with multiplicity 1, and 6 with multiplicity 1.
The function is:
[tex]f(x) = -x^5 + 9x^4 - 18x^3[/tex]
Simplifying by [tex]-x^3[/tex]:
[tex]f(x) = -x^3(x^2 - 9x + 18)[/tex]
The zeroes are the values of x for which:
[tex]f(x) = 0[/tex]
[tex]-x^3 = 0 \rightarrow x = 0[/tex]
0 has multiplicity 3.
And:
[tex]x^2 - 9x + 18 = 0[/tex]
Quadratic equation with [tex]a = 1, b = -9, c = 18[/tex].
[tex]\Delta = (-9)^{2} - 4(1)(18) = 9[/tex]
[tex]x_{1} = \frac{-(-9) + \sqrt{9}}{2(1)} = 6[/tex]
[tex]x_{2} = \frac{-(-9) - \sqrt{9}}{2(1)} = 3[/tex]
6 and 3 with multiplicity 1, thus option B.

1,006 in scientific notation
Answer:
1.006 × 10³
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.
Follow the steps below to see how 1,006 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 1,006
New Number: 1.006
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 0 0 6
Decimal Count: 1 2 3
There are 3 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10^b
a = 1.006
b = 3
Now the whole thing:
1.006 x 10³
Step 4
Check your work:
10³ = 1,000 x 1.006 = 1,006
Hope this helped.

A grocery store sells 2 boxes of cereal for $4.95. Which method can be used to
find the total cost c of purchasing n boxes of cereal?
O Multiply n by the cost of one box.
O Multiply n by c.
O Divide n by the cost of one box.
Divide n by c.
Answer:
Multiply n by the cost of the box.
Step-by-step explanation:
hey there,
< For these kinds of problems I always like making ratio tables.
2 boxes → $4.95
n boxes → $?
To find the thing we don't know in any ratio table (marked by "?"), you have to multiply the two opposites and then divide by the last one standing. I know that sounds confusing so let me explain...
"Two opposites" means the two values that are right across from each other, but do not include the unknown ("?"). In this example, the two diagonally across from each other are "n" amd "4.95". "2" and "?" can't be right across from each other because one of those is a "?".
Multiply the two opposites. n × 4.95. Let's not actually simplify since this isn't what we are doing here in this question and leave it like this:
n × 4.95 = (n × 4.95)
Now that we found that, we have to divide it by the last number available. The last number available that we haven't used yet is "2" (it obbviously can't be the unkown number "?").
(n × 4.95)/2
Whatever the result of the above equation is, is the answer.
(n × 4.95)/2 = ?
In our situation, "?" means "c". This is how you would solve any ratio table, it might seem tricky at first but it's actually super easy.
In this question, we are not asked to divide by two because they want to know a method of solving using the cost of one box.
[tex]\frac{(n*4.95)}{2} / 2[/tex]
n × (4.95/2)
4.95/2 is the cost of one box. Multiply that by "n" and there is your final answer. >
I seriously hoped this help cause this question was kind of hard to explain. Feel free to ask anything else.
41 out of 50 women surveyed liked perfume. what percentage of women did NOT like perfume
Answer:
18%
Step-by-step explanation:
Long Version: 41/50 = 0.82 and when you move the decimal two places right, you will get 82%. 100%-82%= 18%
Short Version: 9/50 people didn't like perfume. 9/50= 0.18 then you move the decimal two places right and it becomes 18%.
Answer
18% of women do not like perfume.
Step-by-step explanation:
First do 50-41, which is 9 to find out how many women don't like perfume. Next you find the percentage by doing 9/50 = 0.18 then you multiply 0.18 by 100. Finally you get 18%.

Identify the type of function that models the situation below: The cost of mailing a letter is $0.37 for the first ounce and $0.23 for each additional ounce or portion thereof. a. greatest integer function b. step function c. absolute value function
Answer: Option a.
Step-by-step explanation:
The data is:
The cost of mailing a letter is $0.37 for the first ounce.
$0.23 for each additional ounce or portion.
Then if we define the variable n, as the number of additional ounces, we can write this as:
F(n) = $0.37 + n*$0.27
This seems to be a linear relationship, but n only can take whole numbers, this means that if n is equal to 0.37, we should round it up (because we already have more than only one ounce).
Then we round up all the non-integers to the next integer.
for example, we round 1.45 to 2 and 1.876 to 2.
This means that F (1.45) = F(1.876) = F(2) = $0.37 + 2*$0.27
This is called a greastet integer function. then the correct option is a.

Zoey is trying to write an equation in slope intercept form. She knows slope intercept form is y=mx+b. She is given the slope is 3 and the y intercept is 10. When she plugs it in she gets 10=3x+b. What mistake did zoey make and how can she fix it?
Answer:
the mistake that zoey had made while writing the equation was putting the y-intercept in the wrong place.in the slope intercept from the equation is y=mx+b.y is the product or the line, m is the slope, b is the y-intercept, the actual equation should be y=3x+10,instead what zoey had which was 10=3x+b. she guessd by pairing the y-intercept with y instead of b.

If a square has a side length of x + 4 and a perimeter of 44 cm, what is
the value of x. *
Square are the same size all the way around, which means every side = x + 4
The perimeter of a square = 4 * side
the perimeter = 44 cm
Let's plug our values into the formula above.
44 cm = 4 * (x + 4)
Distribute the 4
44 cm = 4x + 16
Subtract 16 from both sides
28 cm = 4x
Divide both sides by 4
7 = x

A wheelchair ramp that is constructed to rise 1 foot off the ground must extend 12 feet along the ground. How long will the wheelchair ramp be? Round your answer to the NEAREST HUNDREDTH.
Answer:
Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade).
Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree angle; 12.5% grade).
Minimum width should be 36" (inside rails) - (48" is ideal).
The "deck" or surface of the ramp should be set down between a side-rail assembly such that there is about a 2" curb or lip along the edges of the ramp surface. Decking could consist of 1" X 6" pressure treated pine, (or 3/4" pressure treated plywood applied to a frame).
If possible, the end of the deck (where it meets the lower ground surface) should be beveled to provide a smooth transition from the ramp to level ground. Alternatively, a sheet of 10 Ga. steel at least 10" long and sized to fit the width of the ramp could be used to span the space between the deck surface and the walk or driveway surface at the end of the ramp. This piece should overlap the ramp deck by 2" and be fastened securely with 4 large countersunk flat-head wood screws.
A level platform of at least 5' X 5' should be at the top of ramp to allow for wheelchair maneuvering. If the entrance way opens outward, there should be 1' of surface area extending from the side of the door opening to allow motion to the side without backing the chair during door opening. This landing should not be considered part of the overall "run"/length of the ramp. Any turning point along the ramp needs a level landing. If the turn is a right angle (90 degrees), the landing should be a minimum of 5' by 4'. If a "switchback" of 180 degrees is constructed, the level landing should measure at least 5' X 8'. Ramps longer than 30' should provide a platform every 30' for purposes of safety and to create opportunity for rest
Step-by-step explanation:
The length of the ramp nearest to the hundredth will be 12.04 feet.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
A wheelchair slope that is developed to rise 1 foot off the ground should expand 12 feet along the ground.
The length of the ramp will be given as,
H² = P² + B²
H² = 12² + 1²
H² = 144 + 1
Simplify the equation further, then we have
H² = 145
H = √145
H = 12.04 feet
The length of the slope closest to the 100th will be 12.04 feet.
