Answer:

It is fuzzy but it looks like ∠A is 35°. If that's correct, then:

∠D = 35°

(if ∠A is 36°, then ∠D is 36°)

Step-by-step explanation:

It is indicated that ∠C and ∠F are 90°.

It is also indicated that ∠B and ∠E are equal.

Therefore, ∠A = ∠D

Answer:

the correct answer is <D is 72 degrees

Step-by-step explanation:

x + 36=180°

x= 180-36

x=144°

To find angle d divide your answer by 2

therefore angle d is 72°

Lim (n/3n-1)^(n-1) n → ∞

n200080 [17]

Looks like the given limit is

$\displaystyle \lim_{n\to\infty} \left(\frac n{3n-1}\right)^{n-1}$

With some simple algebra, we can rewrite

$\dfrac n{3n-1} = \dfrac13 \cdot \dfrac n{n-9} = \dfrac13 \cdot \dfrac{(n-9)+9}{n-9} = \dfrac13 \cdot \left(1 + \dfrac9{n-9}\right)$

then distribute the limit over the product,

$\displaystyle \lim_{n\to\infty} \left(\frac n{3n-1}\right)^{n-1} = \lim_{n\to\infty}\left(\dfrac13\right)^{n-1} \cdot \lim_{n\to\infty}\left(1+\dfrac9{n-9}\right)^{n-1}$

The first limit is 0, since 1/3ⁿ is a positive, decreasing sequence. But before claiming the overall limit is also 0, we need to show that the second limit is also finite.

For the second limit, recall the definition of the constant, e :

$\displaystyle e = \lim_{n\to\infty} \left(1+\frac1n\right)^n$

To make our limit resemble this one more closely, make a substitution; replace 9/(n - 9) with 1/m, so that

$\dfrac{9}{n-9} = \dfrac1m \implies 9m = n-9 \implies 9m+8 = n-1$

From the relation 9m = n - 9, we see that m also approaches infinity as n approaches infinity. So, the second limit is rewritten as

$\displaystyle\lim_{n\to\infty}\left(1+\dfrac9{n-9}\right)^{n-1} = \lim_{m\to\infty}\left(1+\dfrac1m\right)^{9m+8}$

Now we apply some more properties of multiplication and limits:

$\displaystyle \lim_{m\to\infty}\left(1+\dfrac1m\right)^{9m+8} = \lim_{m\to\infty}\left(1+\dfrac1m\right)^{9m} \cdot \lim_{m\to\infty}\left(1+\dfrac1m\right)^8 \\\\ = \lim_{m\to\infty}\left(\left(1+\dfrac1m\right)^m\right)^9 \cdot \left(\lim_{m\to\infty}\left(1+\dfrac1m\right)\right)^8 \\\\ = \left(\lim_{m\to\infty}\left(1+\dfrac1m\right)^m\right)^9 \cdot \left(\lim_{m\to\infty}\left(1+\dfrac1m\right)\right)^8 \\\\ = e^9 \cdot 1^8 = e^9$

So, the overall limit is indeed 0:

$\displaystyle \lim_{n\to\infty} \left(\frac n{3n-1}\right)^{n-1} = \underbrace{\lim_{n\to\infty}\left(\dfrac13\right)^{n-1}}_0 \cdot \underbrace{\lim_{n\to\infty}\left(1+\dfrac9{n-9}\right)^{n-1}}_{e^9} = \boxed{0}$

C. neither. the roof and walls are the same shade of green

Step-by-step explanation:

The first batch:

Some white and some green

The second batch:

Triple amount of white and triple amount of green

As we see the ratio of white to green has not changed

Therefore there won't be any difference in painting

Correct answer choice is C.

Plz help me plz I need help I will mark brainlest for the answer

Alexxx [7]

Answer:

2/3

Step-by-step explanation:

Simplifying the Complex Fraction

Convert Mixed Numbers to Fractions

56114=5654

Method 1 : LCD Multiplication

The LCD for 6 and 4 is 12

Multiply top and bottom by the LCD

12×5612×54=1015

convert to mixed numbers and

reduce fractions where possible

=1015=23

Method 2 : Fraction Division

Divide the top fraction by the bottom

(multiply top by reciprocal of bottom)

56÷54

=56×45

=2030

convert to mixed numbers and

reduce fractions where possible

=2030=23

How can N+4/3=1/3,What is the value of N

ivann1987 [24]

N + 4 / 3 = 1 / 3

Multiply both sides by 3 :

3* ( N + 4 / 3 ) = 3 * ( 1 / 3 )

∴

N + 4 = 1

Subtract 4 from both sides:

N + 4 - 4 = 1 - 4

N = - 3

hope this helps !.
