First derivative is e^x(x^2-7x+13)+e^x(2x-7)
Which can be simplified to e^x(x^2-7x+13+2x-7)
Second derivative is e^x(x^2-5x+6)+e^x(2x-5)
Which then can be simplified to e^x(x^2-3x+1)

Answer:

20%

Step-by-step explanation:

Well, it's actually relatively simple.

The first thing to do would be to write this in a fraction form. You payed 72,000 out of 360,000.

72,000/360,000.

now you take that fraction, and convert it's to its decimal form which will give you a 0.2.

0.2 in decimal form is converted to 20.0% (when you convert a decimal to a fraction, you multiply by 100, or move the decimal two places to the right).

Another way to do this is simplifying the fraction.

take 72,000/360,000 and find what X is when

72,000/360,000 = x/100

you will find that 72,000/360,000 Is equal to 20/100. since percents are calculated as out of a hundred. your answer would still come out as 20%

Answer:

324°

Step-by-step explanation:

Totak angles in a 7 sided polygon = 900°

Side A = 3

Side B = 1

Side C = 4

Side D = 1

Side E = 5

Side F = 9

Side G = 2

Total = 25

The largest angle has the largest ratio which is side F

Angle in side F = Ratio of side F / total ratio × 900°

= 9/25 × 900°

= 0.36 × 900°

= 324°

The largest angle = 324°

The smallest angles are angles with the lowest ratio which are side B and side D

Angle in side B = Ratio of side F / total ratio × 900°

= 1/25 × 900°

= 0.04 × 900°

= 36°

The smallest angles are angles 36°

A fruit stand has 28 apples, 20 oranges, and 12 pears. What is the ratio of apples to the total pieces of fruit?
ruslelena [56]
Data:
Apples = 28
Oranges = 20
Pears = 12

<span>What is the ratio of apples to the total pieces of fruit?
Solving:
</span>\frac{apples}{apples+oranges+pears} =  \frac{28}{28+20+12} =  \frac{28}{60} \frac{\div4}{\div4} \to\:\boxed{\boxed{ratio = \frac{7}{15}}}\end{array}}\qquad\quad\checkmark<span>

Answer:

B

Step-by-step explanation:

Comparing like terms on both sides

x^{6} → x²

Note that x² = \sqrt[3]{x^{6} }

y^{12} → y^{4}

Note that y^{4} = \sqrt[3]{y^{12} }

Also

54 → 3

Note that 54 = 3³ × 2

and \sqrt[3]{54} = \sqrt[3]{3^{3}(2) } = 3\sqrt[3]{2}

Hence

\sqrt[3]{54x^{6}y^{12}  } = 3x²y^{4}\sqrt[3]{2}

Hence n = 3 → B
