Answer:
First of all expand the terms
2x(1-x)³ = 2x( 1 - 3x + 3x² - x³)
Multiply by 2x
You will get
2x - 6x² + 6x³ -2x⁴
Differentiate each of the terms using differentiation rules
You will get
2 - 12x + 18x² - 8x³
So the final answer is
- 8x³ + 18x² - 12x + 2
Hope this helps.

All the values of a 12-sided die will be represented by two 6-sided die. The probability of rolling a 7 on the 12-sided die is 1/12 and rolling a sum of 7 on the two 6-sided dice will be 1/6.
The 12-sided die which is dodecahedral consists of numbers up to 12. The 6-sided die consists of numbers up to 6. The suggestion of using two 6-sided dice instead of a 12-sided die will make a difference in the probabilities of a specific outcome.
Although, using a pair of 6-sided dice and adding their scores will represent all the values or outcomes you can get in a 12-sided die but still there will be a difference in the probabilities.
If we find the probability of rolling 7 on the 12-sided die, then it will be 1/12.
But, in the case of two 6-sided dice, we will obtain the sum of 7 in 6 outcomes which are (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1). The total number of outcomes, in this case, is 36.
Therefore, the probability of rolling a sum of 7 on the two 6-sided dice will be 6/36 = 1/6.

Toula owns the Pita Pan restaurant. She needs to order supplies for the upcoming weekend rush. She needs 150 bags of pita bread. The bread come in crates of 50, and each crate costs $15.00. She also needs 65 containers of hummus dip. There are 5 containers in a box, and each box costs $20.00 What expressions can Toula use to determine how much the pita bread and hummus dips will cost? What will the total be?
The total cost of the pita bread and hummus dips will be $305.00.
To determine the cost of the pita bread and hummus dips, Toula can use the following expressions:
Cost of pita bread:
Number of crates needed = (150 bags) / (50 bags/crate) = 3 crates
Cost of each crate = $15.00
Total cost of pita bread = (Number of crates needed) × (Cost of each crate) = 3 crates × $15.00/crate = $45.00
Cost of hummus dips:
Number of boxes needed = (65 containers) / (5 containers/box) = 13 boxes
Cost of each box = $20.00
Total cost of hummus dips = (Number of boxes needed) × (Cost of each box) = 13 boxes × $20.00/box = $260.00
Therefore, the expressions Toula can use to determine the costs are:
Cost of pita bread = 3 crates × $15.00/crate
Cost of hummus dips = 13 boxes × $20.00/box
The total cost will be the sum of the costs of pita bread and hummus dips:
Total cost = Cost of pita bread + Cost of hummus dips
Total cost = $45.00 + $260.00
Total cost = $305.00
Therefore, the total cost of the pita bread and hummus dips will be $305.00.

The radius of a circle is 33 cm. What is the area of the circle? Give your answer to 1 d.p.
The area of the circle with radius 33 cm is 3419.5 square centimeters.
According to the question,
We have the following information:
Radius of the circle = 33 cm
We know that the following formula is used to find the area of the circle:
Area of the circle = π\(r^{2}\) where r is the radius of the circle
There are two approximate values of π which are 22/7 and 3.14. In this case, we will use the value of π as 3.14.
So, we have the following expression:
Area of the circle = 3.14*33*33
Area of the circle = 3419.46 square centimeters
Rounding it off to one decimal point:
3419.5 square centimeters
Hence, the area of the circle with radius 33 cm is 3419.5 square centimeters.

You are buying a used car which costs $10,200. You plan to sell the car after keeping it for 5 years. Research shows that this car will lose value at a rate of 8% per year. How much will the car be worth after 5 years?
Answer:
$6,722.63
Step-by-step explanation:
Now: $10,200
In 1 year: 0.92 × $10,200 = $9,384
In 2 years: 0.92 × $9,384 = $8,633.28
In 3 years: 0.92 × $8,633.28 = $7,942.6176
In 4 years: 0.92 × $7,942.6176 = $7,307.208192
In 5 years: 0.92 × $7,307.208192 = $6,722.63
Answer: $6,722.63
Answer:
$6,722.63
Step-by-step explanation:
Using this formula A=P(1-d/100)^n where
A = Amount
P = Principal
d = percent
n = number of year
A=P(1-d/100)^n
A = 10,200(1-8/100)⁵
A = 10,200(1-0.08)⁵
A = 10,200(0.92)⁵
A = 10,200(0.6591)
A= $6,722.63
Is the following sequence a geometric sequence? If so, find its common ratio. 6,24,96,384,1536,…
Answer:
The given sequence is a geometric sequence and the common ratio is 4
Step-by-step explanation:
A geometric sequence is a sequence in which the next term is obtained by multiplying the previous term with a ratio r.
Given sequence is:
6,24,96,384,1536,…
Here
a1 = 6
a2 = 24
a3 = 96
a4 = 384
a5 = 1536
The common ratio is the ratio between consecutive terms of a geometric sequence.
If the common ratio of a sequence is same, then the sequence is a geometric sequence.
So,
\(r = \frac{a_2}{a_1} = \frac{24}{6} = 4\\r = \frac{a_3}{a_2} = \frac{96}{24} = 4\\r = \frac{a_4}{a_3} = \frac{384}{96} = 4\\r = \frac{a_5}{a_4} = \frac{1536}{384}= 4\)
As the common ratio is same, the given sequence is a geometric sequence.
Hence,
The given sequence is a geometric sequence and the common ratio is 4

Zoe placed colored blocks on a scale in science class. Each block weighed 0.8 ounces. The total weight of all the colored blocks was 12.8 ounces. How many blocks did Zoe place on the scale? Write and solve an equation to find the answer.
Answer:
16 blocks
Step-by-step explanation:
equation: 0.8x = 12.8
if each block is 0.8oz and the total weight is 12.8oz then divide 12.8 by 0.8 and get 16! in other words, 0.8oz goes into 12.8oz 16 times, meaning there are 16 blocks that each weigh 0.8oz

Hello!
We have all angles of the triangle:
We will use the law of cosines. This relation is valid for all sides of any t
We have:
angle A = 12°
côté a = 10
angle B = 150°
This is therefore the first case of application of the sine law.
So:
\(\sf \dfrac{b}{sin~B} = \dfrac{a}{sin~A}\)
\(\sf b =\dfrac{sin~B~*~a}{sin~A} = \dfrac{sin~150~*~10cm}{sin~12} = \dfrac{arcsin~0.5~*~10cm}{arcsin~0.2079116908} = \dfrac{30~*~10cm}{12} = \dfrac{300cm}{12} = \boxed{\sf25cm}\)
b = 25cmA piece of land is shaped like a right triangle. Two people start at the right angle at the same time, and walk at the same speed along different legs of the triangle while spraying the land. If the area covered is changing at
5 m2/s, how fast are the people moving when they are 5 m from the right angle? (Round approximations to two decimal places.)
Answer:
1 m/s
Step-by-step explanation:
the area of the triangle = A = ¹/₂ab
where a is the distance covered by the first person and b is the distance covered by the second person. since they walk at the same speed, then a = b, so our formula can be changed to A = ¹/₂x²
now we find the derivative of both sides:
dA/dt = ¹/₂ ⋅ dx²/dt
dA/dt = ¹/₂ ⋅ 2x ⋅ dx/dt
dA/dt = x ⋅ dx/dt = x ⋅ velocity
we are told that x = 5 m, and dA/dt = 5 m²/s
velocity = dA/dt / x
velocity = 5 m²/s / 5 m = 1 m/s

Solve the equation for w.
4w + 2 + 0.6w = −3.4w − 6
No solution
w = 0
w = 1
w = −1
Answer:
w = -1
Step-by-step explanation:
Given equation:
\(4w + 2 + 0.6w=-3.4w-6\)
Add 3.4w to both sides:
\(\implies 4w + 2 + 0.6w+3.4w=-3.4w-6+3.4w\)
\(\implies 4w + 2 + 0.6w+3.4w=-6\)
Subtract 2 from both sides:
\(\implies 4w + 2 + 0.6w+3.4w-2=-6-2\)
\(\implies 4w +0.6w+3.4w=-6-2\)
Combine the terms in w on the left side of the equation and subtract the numbers on the right side of the equation:
\(\implies 8w=-8\)
Divide both sides by 8:
\(\implies \dfrac{8w}{8}=\dfrac{-8}{8}\)
\(\implies w=-1\)
Therefore, the solution to the given equation is:
\(\boxed{w=-1}\)
Given that,
→ 4w + 2 + 0.6w = -3.4w - 6
Now the value of w will be,
→ 4w + 2 + 0.6w = -3.4w - 6
→ 4.6w + 2 = -3.4w - 6
→ 4.6w + 3.4w = -6 - 2
→ 8w = -8
→ w = -8/8
→ [ w = -1 ]
Hence, the value of w is -1.
A mutual fund pays 15% compounded monthly. How much should I invest now so that 22 months from now I will have $4700 in the account?
To solve this problem, we will use the formula for compound interest:
\(P_N=P_0\cdot(1+\frac{r}{k})^{N\cdot k}.\)Where:
• P_N is the amount of money after N years,
,• P_0 is the initial amount of money,
,• r is the interest in decimals,
,• k is the number of compounded periods.
In this case, we have:
• P_N = $4700,
,• r = 15% = 0.15,
,• k = 12 (because the interest is compounded monthly),
,• N = 22/12 (we divide the # of months by the # of months in a year).
Replacing these data in the formula above, we have:
\(\begin{gathered} 4700=P_0\cdot(1+\frac{0.15}{12})^{\frac{22}{12}\cdot12}, \\ 4700=P_0\cdot(1+\frac{0.15}{12})^{22}.^{} \end{gathered}\)Solving for P_0 the last equation, we get:
\(P_0=\frac{4700}{(1+\frac{0.15}{12})^{22}}\cong3576.08.\)We found that the initial amount of money must be $3576.08.
Answer
I must invest $3576.08 now so that 22 months from now I will have $4700 in the account.
