Answer:

2) \displaystyle -9a^3b^5

1) \displaystyle \frac{x^8}{3}

Step-by-step explanation:

2) \displaystyle \frac{(27a^3b^3)(-2ab^4)}{6ab^2} \Rightarrow \frac{(3ab)^3(-2ab^4)}{6ab^2} \\ \\ \boxed{-9a^3b^5} \rightarrow \frac{-54a^4b^7}{6ab^2}

1) \displaystyle \frac{16x^{10}y^2}{48x^2y^2} \Rightarrow \frac{(-4x^5y)^2}{48x^2y^2} \\ \\ \boxed{\frac{x^8}{3}}

The Quotient-to-Power Rule states that whenever you are dividng like-terms, you <em>keep</em> the coefficients and deduct the exponents.

Use the figure to find the angle m
nordsb [41]

Answer:

Measure of angle M = 41°

Step-by-step explanation:

From the figure attached,

NM ≅ NO [Given]

Therefore, ∠O ≅ ∠M [Opposite angle of the equal sides]

By triangle sum theorem,

m∠O + m∠N + m∠M = 180°

m∠O + m∠N + m∠O = 180° [Since, ∠M ≅ ∠O]

By substituting the values of the given angles,

(4y - 15)° + (7y)° + (4y - 15)° = 180°

(15y - 30) = 180

15y = 210

y = 14

Therefore, m∠M = (4y - 15)°

                           = 4(14) - 15

                           = 56 - 15

                           = 41°

Find a particular solution to y" - y' + 9y = 3 sin 3x
Dima020 [189]

Answer:

cos3x

Step-by-step explanation:

y" - y' + 9y = 3 sin 3x

D^{2}y-Dy+9y=3 sin3x

y=\frac{3 sin 3x}{(D^{2} -D+9}=3 sin 3x

here D^2 will be replaced by  \alpha^2 where \alpha is coefficient of x

y=\frac{3 sin 3x}{-3^{2} -D+9}

y=-3\frac{sin 3x}{D}

y=-3\int\ {sin 3x} \, dx

y=-3\frac{cos3x}{-3}

y=cos3x

hence Particular solution is cos3x

Michael was 1.0 metres tall, and could
Artist 52 [7]

Answer:

Lucy must walk up 80 steps to reach the 6th floor.

Step-by-step explanation:

Since Michael was 1.0 meters tall, and could only reach up to the 1st floor lift button, and from the 1st floor, he had to walk up 100 steps to reach the 6th floor; while Vinh was 1.4 meters tall, and could reach the 5th floor button, and he had to walk up 20 steps to reach the 6th floor; If Lucy was 1.1 meters tall, to determine how many steps did she have to walk up to reach the 6th floor, the following calculation must be performed:

1 = 100

1.4 = 20

1.4 - 1 = 100 - 20

0.4 = 80

0.1 = X

0.1 x 80 / 0.4 = X

20 = X

100 - 20 = 80

Therefore, Lucy must walk up 80 steps to reach the 6th floor.

Here are some (simulated) data on the maximum age distribution in rabbits:
bogdanovich [222]

Let Y denote the maximum age of rabbit.

To calculate probability for Y=a from given table, we need to divide frequency corresponding to y=a with sum of frequencies.

For example P(Y=0) = \frac{37}{37+232+429+388+225+99+58+10+6+0} =\frac{37}{1484} = 0.02493

Like that P(y=1) = 0.1563, P(Y=2) = 0.2891, P(y=3) = 0.2615, P(Y=4) = 0.1516,

P(Y=5) = 0.0667, P(Y=6) = 0.0391,P(Y=7) = 0.0067, P(Y=8)=0.004 and P(Y=9) =0.

a) P(Y>5) = P(Y=6)+P(Y=7)+P(Y=8)+P(Y=9)

              = 0.0391+0.0067+0.004+0 = 0.0498

b) P(2<Y<6) = 0.2615+0.1516+0.0667 = 0.4798

c) P(Y≥3) = 0.2615+0.1516+0.0667+0.0391+0.0067+0.004+0= 0.5296

d)P(Y<6) = 0.02493+0.1563+0.2891+0.2615+0.1516+0.0667 =0.95013

e)If we add (a) and (d), we will get 0.0498+0.95013 = 0.99993≈1

Not surprised,since this is nothing but addition of probabilities for all Y values.

That's we got 1 since numerator and denominator are same.
