Answer: The answer is D

Step-by-step explanation:

Factor and set each set equal to zero to get x=0,2,-1,1

Answer:

D

Step-by-step explanation:

x¹³ - 2x¹² - x¹¹ + 2x¹⁰ = 0

x¹⁰(x³ - 2x² - x + 2) = 0

x¹⁰ [x²(x - 2) - (x - 2)] = 0

x¹⁰(x² - 1)(x - 2) = 0

x = 0 (multiplicity 10)

x = 1

x = -1

x = 2

The cans of paints and areas are illustrations of equivalent ratios.

5.5 cans are needed to paint an area of 2200 units square

The given parameter is:

[tex]\mathbf{Cans : Area = 1 : 400}[/tex]

Express as fraction

[tex]\mathbf{\frac{Cans }{ Area }= \frac{1 }{ 400}}[/tex]

Multiply both sides by Area

[tex]\mathbf{Cans= \frac{1 }{ 400} \times Area}[/tex]

When the area is 2200, we have:

[tex]\mathbf{Cans= \frac{1 }{ 400} \times 2200}[/tex]

[tex]\mathbf{Cans= 5.5}[/tex]

Hence, 5.5 cans are needed to paint an area of 2200 units square

5.5 cans of paint are required to cover an area of 2200 square units, but since you can't have half a can, you would actually need 6 cans of paint.

This problem can be solved using simple division, which is a common concept in Mathematics. Given that one can of paint covers 400 square units, to find out how many cans of paint are needed to cover an area of 2200 square units, we need to divide the total area by the area that one can covers. So, 2200 ÷ 400 = 5.5.

However, you cannot have half a paint can, so you would need 6 cans of paint to fully cover the area. Here, we apply the mathematical principle of rounding up because you can't use half a can of paint.

Answer:

  64 cm²

Step-by-step explanation:

Suppose the original paper was x cm on a side. Then the original perimeter was 4x.

When the square is folded in half, two of the sides are now x/2, so the perimeter is ...

  x + x/2 + x + x/2 = 3x

If 3x = 24 cm, then x = 8 cm.

The area of the original paper is ...

  A = x² = (8 cm)² = 64 cm²

Answer:

The correct answer to this problem is the second option: YZ is the longest side.

Step-by-step explanation:

In order to solve this problem, we need to understand the relationship between angle measure and side lengths in a triangle.  

In a triangle, the longest side is located across from the largest angle measure, the smallest side is located across from the smallest angle, and the middle length side is located across from the medium sized angle.

Using this knowledge, we can conclude that since XYZ is the smallest angle, XZ must be the smallest side.  We can also state that since YXZ is the largest angle, YZ is the longest side.  

Looking at the answer options, the only choice that aligns with this information is the second option: YZ is the longest side, and thus we can conclude that this is the correct answer.

Hope this helps!

Using the continuous compounding formula A = Pe^rt, Katie's account balance after 10 years will be approximately $103,204, with her initial investment of $33,750 at an annual interest rate of 11.17%.

To calculate what Katie's account balance will be in 10 years, with an investment of $33,750 at 11.17% compounded continuously, we use the formula for continuous compounding:

A = Pert

Where:

Plugging in the values we get:

A = $33,750 * e(0.1117 * 10)

Calculating the exponent:

A = $33,750 * e1.117

Calculating the future value:

A = $33,750 * 3.0579 (approximate value of e1.117)

A = $103,204

Katie's account balance after 10 years will be approximately $103,204.

17 pieces. She had two and she had to have 15 to give to the children. If each child got 3 and there is 5. This turns into 3*5=15. Then you would add 15+2 to get 17

Sara initially had 17 candies. This computation is based on the 2 pieces she kept for herself and the three pieces of candy each of her five children received.

The subject of this question is mathematics, specifically it deals with basic arithmetic and problem solving. According to the problem, Sara kept 2 pieces of candy for herself and then gave each of her 5 children 3 pieces. In mathematical terms, this can be represented as an equation: 2 (pieces Sara kept) + 5 (children) * 3 (pieces each child received) = Total pieces of candy Sara had initially.

To solve this equation, first multiply the number of children by the pieces each received: 5 * 3 = 15. Then add the pieces Sara kept: 2 + 15 = 17. Therefore, Sara initially had 17 pieces of candy.

Answer:

  D.  543.46

Step-by-step explanation:

The formula for the remaining balance on the loan is ...

  A = P(1 +r)^n +p((1 -(1 +r)^n)/r)

where P is the principal, p is the monthly payment, r is the monthly interest rate, and n is the number of months.

We have P=135,000, p = TBD, r = 3.6%/12 = .003, n = 20×12 = 240.

___

The monthly payment is given by the same formula by setting A=0. In this case, n is 25 years, or 300 payments. Solving for p, we get, ...

  p = Pr(1 +r)^n/((1 +r)^n -1) = Pr/(1 -(1 +r)^-n)

So, the monthly payment is ...

  p = 135,000×0.003/(1 -1.003^-300) = 683.10

Using this value in the formula for remaining balance, we get ...

  A = 135000(1.003^240) +683.10((1 -1.003^240)/0.003) = 37,459.20

[tex]W=|F|*|r|cos(\theta)[/tex]

In this case

[tex]\theta=30\°[/tex]

|F|=180 pound force

The magnitude of vector AB is:

[tex]|r|= \sqrt{5^2 + 2^2}\\\\|r|= \sqrt{29}\ fr[/tex]

Finally the work is:

[tex]W=180*\sqrt{29}*cos(30\°)[/tex]

[tex]W=839.464\ ft*lbf[/tex]

Answer:

the answer is option 1, A

Step-by-step explanation:

The answer is:

[tex]t_1=3.60s\\t_2=7.94s[/tex]

Time equal to 3.30 seconds when the arrow was going up.

Time time equal to 7.94 seconds when the arrow was going down.

To solve the problem, we need to solve the quadratic equation and find the value of values of time where the height of the arrow is 420 feet.

Also, we are given some information, we need to substitute it and then use the quadratic equation.

The equation is:

[tex]h=-16t^{2}+vot\\\\-16t^{2}+vot-h=0[/tex]

Substituting the given information we have:

[tex]-16t^{2}+vot-h=0[/tex]

[tex]-16t^{2}+180\frac{ft}{s} t-420=0[/tex]

We have a quadratic equation where:

[tex]a=-16\\b=180\\c=-420[/tex]

Now, using the quadratic equation to find the value or values of "t", we have:

[tex]\frac{-b+-\sqrt{b^{2}-4ac } }{2a}[/tex]

[tex]\frac{-180+-\sqrt{180^{2}-4*-16*-420 } }{2*-16}=\frac{-180+-\sqrt{32400-26880 } }{-32}\\\\\frac{-180+-\sqrt{32400-26880}}{-32}=\frac{-180+-\sqrt{5520}}{-32} \\\\\frac{-180+-\sqrt{5520}}{-32}=\frac{-180+-(74.29)}{-32}\\\\t_1=\frac{-180+(74.29)}{-32}=3.30\\\\t_2=\frac{-180-(74.29)}{-32}=7.94[/tex]

Hence, we have two positive values of time, it means that there are two moments of time where the height of the arrow is equal to 420 feet, those times are:

[tex]t_1=3.60s\\t_2=7.94s[/tex]

Time equal to 3.30 seconds when the arrow was going up.

Time equal to 7.94 seconds when the arrow was going down.

Have a nice day!

Answer:

3.3secs, 7.9secs

Step-by-step explanation:

We are looking for the number of seconds it takes the arrow to reach a height of 420ft. We are given the projectile formula h=−16t2+v0t, where h is the height, in feet, and t is the time, in seconds. We can substitute the initial velocity v0=180 and desired height h=420 to find

420=−16t2+180t

Rewriting this quadratic equation in standard form, we have

16t2−180t+420=0

Now that the equation is in standard form, at2+bt+c=0, we can identify the coefficients a=16, b=−180, and c=420. Substituting these into the quadratic formula, we have

t=−b±b2−4ac‾‾‾‾‾‾‾‾√2a=−(−180)±(−180)2−4(16)(420)‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√2(16)=180±5520‾‾‾‾‾√32

The approximate values for t are

t=≈180+5520‾‾‾‾‾√327.9andt=≈180−5520‾‾‾‾‾√323.3

The arrow will go up and then fall down. As the arrow goes up, it will reach 420ft after approximately 3.3s. It will also pass that height on the way down at approximately 7.9s.

Answer:

  $48.97

Step-by-step explanation:

Let p represent the marked price of the mower. Then the price with tax is ...

  with tax = p + 7.3%×p = 1.073p

The amount Flicka paid is the amount tendered less the change she received, so is ...

  3×$20 - 7.45 = with tax = 1.073p

To find p, we can divide by its coefficient:

  (3 × $20 - 7.45)/1.073 = p ≈ $48.97

The selling price before taxes was $48.97.

_____

Comment on the problem

If you check the answer, you find the amount with tax is ...

  $48.97 × 1.073 ≈ $52.54481 ≈ $52.54

so the change Flicka would have received would have been $7.46, not $7.45. If the price were $48.98, then the change would have been $7.44. There is no price at which the mower can be marked that will make the total with tax come to $52.55. There is no solution to this problem.

Answer:

$48.97

Step-by-step explanation:

She paid three $20 bills

3 × 20 = $60

She received $7.45 change

60 - 7.45 = $52.55

The mower was for $52.55 with sales tax.

The sales tax is 7.3%.

Before the sales tax (reduce tax).

Answer:

Unusual

Step-by-step explanation:

we know that

The z-score is a measure of how close the given data point is to the mean of the values given with the standard deviation

so

if its z-score is greater than or equal to -2, or less than or equal to 2., then the data value is considered ordinary

if its z-score is less than -2 or greater than 2, then the data value is considered unusual

A data value is considered an outlier if its z-score is less than -2 or greater than 2.

Z-scores are a statistical measure that standardizes data, enabling comparisons across different datasets.

A z-score tells us how many standard deviations a data point is from the mean.

When a z-score is below -2 or above 2, it suggests that the data point is significantly distant from the mean of the dataset.

This indicates that the data point is an extreme observation, differing substantially from the rest of the data.

Outliers can be caused by various factors, such as measurement errors, data entry mistakes, or genuine anomalies in the underlying data. Identifying and handling outliers is crucial for robust statistical analysis and modeling.
