Can someone help me with number 15

Mathematics
1 answer:
Shalnov [3]3 years ago
4 0

Answer:

Step-by-step explanation:

We will evaluate that with n values starting at 1 and ending at 5.  To do that, simply replace the exponent n with 1, then 2, then 3, then 4, then 5.

f(1)=(\frac{2}{3})^1  so

f(1)=\frac{2}{3}

Then f(2):

f(2)=(\frac{2}{3})^2 simplifies a bit so maybe it's easier to see how to handle this:

f(2)=(\frac{2^2}{3^2}) so

f(2)=\frac{4}{9}

Then f(3):

f(3)=(\frac{2^3}{3^3})=\frac{8}{27}

And f(4):

f(4)=(\frac{2^4}{3^4})=\frac{16}{81}

And finally, f(5):

f(5)=(\frac{2^5}{3^5})=\frac{32}{243}

The sum of 3 consecutive multiples of 4 is 120. Find the numbers.
Vesnalui [34]

Answer:

The required numbers are: 36, 40, 44

Step-by-step explanation:

Let first number = 4x

Second number = 4(x+1)

Third number = 4(x+2)

There sum = 120

We need to find the numbers

We can write:

4x+4(x+1)+4(x+2)=120\\4x+4x+4+4x+8=120\\12x+12=120\\12x=120-12\\12x=108\\x=\frac{108}{12}\\x=9

So, we get x = 9

Now, finding the numbers:

first number = 4x = 4(9) =36

Second number = 4(x+1) = 4(9+1) = 4(10) = 40

Third number = 4(x+2) = 4(9+2) = 4(11) = 44

So, The required numbers are: 36, 40, 44

The image represents a rectangular patio that has a length equal to 4 feet more than the width. What is the perimeter of the pat
IrinaK [193]

Answer:

  4w+8 feet

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of its sides. Since opposite sides are identical in length, it can be computed as double the sum of adjacent side lengths. Here, the lengths are in feet.

  P = 2(L+W)

  P = 2((w+4) +w)

  P = 4w +8

The perimeter of the patio is 4w+8 feet.
