Answer:

n=10.

Step-by-step explanation:

[tex]\frac{45}{n^{2}-3n-4 }[/tex] - [tex]\frac{3}{n-4}[/tex] = [tex]\frac{2}{n+1 }[/tex]

[tex]\frac{45}{n^{2}-3n-4 }[/tex] -  [tex]\frac{3(n+1)}{(n+1)(n-4)}[/tex] = [tex]\frac{2(n-4)}{(n+1)(n-4) }[/tex]

[tex]\frac{45}{n^{2}-3n-4 }[/tex] -  [tex]\frac{3n+3}{n^{2} -3x-4}[/tex] = [tex]\frac{2n-8}{n^{2} -3x-4 }[/tex]

45-3n-3=2n-8

45-3+8=5n

n=50/5=10

Answers

Answer:

log Subscript 3 Baseline StartFraction z squared Over 4 EndFraction

Step-by-step explanation:

The single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]

Logarithm and indices

Given the logarithmic expression;

[tex]2(log_38+log_3z)-log_3(3^4-7^2)[/tex]

We are to write it as a single logarithm

Using the product and quotient law of logarithm;

[tex]2(log_38+log_3z)-log_3(3^4-7^2)\\=2(log_38+log_3z)-log_3(\frac{81}{49} )\\=2(log_38z)-log(\frac{81}{9})\\=log_364z^2-log(\frac{81}{9})[/tex]

Simplify the final result to have:

[tex]=log_364z^2-log(\frac{81}{9})\\=log_3(\frac{9(64z^2)}{81} )[/tex]

Hence the single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]

For the right triangles below, find the values of the side lengths d and a.
Round your answers to the nearest tenth.

Answers

Answer:

a = 1.4 and d = 6.9

Step-by-step explanation:

To get the value of d and a, we will use the SOH CAH TOA identity

For the first tringle;

Opposite = d ((opposite angle 60 degrees)

Adjacent = 4

Tan theta = opp/adj

Tan 60 = d/4

d  = 4tan60

d = 4(1.732)

d = 6.9

For the second triangle;

Opposite = a

Hypotenuse = 2

Since sin theta = opp/hyp

Sin45 = a/2

a = 2sin45

a = 2(0.7071)

a = 1.4

Hence a = 1.4 and d = 6.9

Step-by-step explanation:

Answer:

Linear, there is a constant rate of change

Step-by-step explanation:

In problem 8-94 you found that if you are given three lengths to build the sides of a triangle, then if a triangle can be formed, all the triangles you could make were the same. Suppose you start with two triangles knowing that their three pairs of corresponding sides are the same, as shown in the diagram below.

Triangle, A B C, where side, A C, has one hatch mark, side, C B, has 2 hatch marks, and side, A B, has 3 hatch marks.

Triangle, P Q R, where side, R P, has one hatch mark, side, P Q, has 2 hatch marks, and side, R Q, has 3 hatch marks.

Examine the diagram. What do you think the markings indicate? Name the pairs of corresponding sides.

What can you say about the two triangles and why? What can you say about their angles? Why?

If the surface areas of two spheres are in ratio 16:9, then their volumes will be in the ratio​

Answers

Answer:

64 : 27

Step-by-step explanation:

If linear ratio is a : b , then

area ratio = a² : b²

volume ratio = a³ : b³

Given area ratio = 16 : 9 , then

linear ratio = [tex]\sqrt{16}[/tex] : [tex]\sqrt{9}[/tex] = 4 : 3

volume ratio = 4³ : 3³ = 64 : 27

How do I make the graph or if anyone makes the graph for me WILL GET BRAINLIEST.

Answers

Answer:

Part A

The required inequality is;

y = 50 - 2 × x  ≥ 20

Please find attached the graph of the inequality created with Microsoft Excel

Part B

The number of weeks she can withdraw is less than or equal to 15 weeks

Step-by-step explanation:

The given parameters are;

The amount Kate has in her savings account at the beginning of the summer = $50

The least amount she wants to have in the account at the end of the summer = $20

The amount she withdraws each weak from the account = $2

Part A

Let 'x' represent the number of weeks she can withdraw money, we have;

The required inequality that gives the number of weeks she can withdraw money is given as follows

y = 50 - 2 × x

y ≥ 20

Therefore, the inequality is;

y = 50 - 2 × x  ≥ 20

The graph of the inequality created with Microsoft Excel is attached

Part B

The number of 'x' weeks she can withdraw is;

50 - 2 × x  ≥ 20

- 2 × x  ≥ 20 - 50 = -30

x ≤  -30/(-2) = 15

The number of weeks she can withdraw is x ≤ 15 weeks.
