can someone answer this 1/9÷4

9514 1404 393

Answer:

  n = 99

Step-by-step explanation:

The sum of logarithms is the log of a product. Here, the sum of terms is ...

  log(2/1) +log(3/2) +log(4/3) + ... +log((n+1)/n)

  = log((2/1)(3/2)(4/3)×...×((n+1)/n)) = log(n+1)

So, the question reduces to ...

  log(n+1) = 2

Taking antilogs, we have ...

  n +1 = 10^2 = 100

  n = 99

The value of n that makes the sum 2 is 99.

Answer:

Step-by-step explanation:

1)

(x-3)/18=12/9, cross multiply

9(x-3)=18(12)

9x-27=216, add 27 to each side

9x=243, divide each side by 9

x=27

2)

(x-16)/(x+6)=3/5, cross multiply

5(x-16)=3(x+6)

5x-80=3x+18, subtract 3x from each side

2x-80=18, add 80 to each side

2x=98, divide each side by 2

x=49

3)

Since the triangles are similar we can say that

25/(4x-1)=10/(x+5), cross multiply

25(x+5)=10(4x-1)

25x+125=40x-10, subtract 40x from each side

-15x+125=-10, subtract 125 from each side

-15x=-135, divide each side by -15

x=9

here are the answers!

Answer:

4 hours

Step-by-step explanation:

We can already assume that the freight train is 60 miles ahead of the express. If the freight is going at a constant of 30 mph and the express goes 50 mph then we can say that when the freight train has been gone for 6 and the express for 4 the express will have passed the freight. The reason as to why would be that 60 + 120 = 180 or 60 + (30 x 4) = 180 and 50 x 4 = 200 .

Sorry if that explanation doesn't make sense but I hope this helped.

Answer:

4th option

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then shift left by a units

• If a < 0 then shift right by a units

-------------------------------------------------

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Then

g(x) = [tex](\frac{1}{4}) ^{x-3}[/tex] + 5

is f(x) shifted 3 units right and 5 units up

Answer:

126 degrees

Step-by-step explanation:

Angle 4 is supplemnetary to angle 3..which means both of their angles add up to 180 degrees

We can take the angle of 3 whihc is 54 degrees and subtract that from 180 to determine angle 4:

180 - 54 = 126

Angle 4 is 126 degrees

Step-by-step explanation:

Answer: Since x2=6, the width of the rectangle is x-6.

Explanation: factor x^2-4x-12.

given that length=x+2 and area of rectangle = length * width

all you have to do is find the width

there are several way to do this, here is one:

Since one factor of x^2-4x-12 is x+2, x1=-2 is a solution to x62-4x-12=0 so in order to find the other solution, you can use the sum and product properties.

x1*x2= -12 with x1=-2, so x2=6.

Since x2=6, the width of the rectangle is x-6.

Answer:

D

Step-by-step explanation:

Given a quadratic function in standard form

f(x) = ax² + bx + c ( a ≠ 0 )

• If a > 0 then minimum value

• If a < 0 then minimum value

For

f(x) = x² + 16x + 3

a = 1 > 0 then f(x) has a minimum value

The minimum is the value of the y- coordinate of the vertex.

The x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

Here a = 1 and b = 16 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{16}{2}[/tex] = - 8

To find the y- coordinate of the vertex, substitute x = - 8 into f(x)

f(- 8) = (- 8)² + 16(- 8) + 3 = 64 - 128 + 3 = - 61

Thus the function has a minimum value of - 61 → D

Answer:

(0, 3 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = (- 4, 8) and (x₂, y₂ ) = (4, - 2) , then

midpoint = ( [tex]\frac{-4+4}{2}[/tex], [tex]\frac{8-2}{2}[/tex] ) = ( [tex]\frac{0}{2}[/tex], [tex]\frac{6}{2}[/tex] ) = (0, 3 )
