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}

Answer:

40

Step-by-step explanation:

Angle Formed by Tangent and Secant = 1/2 (DIFFERENCE of Intercepted Arcs)

< WVT = 1/2 ( WT - UW)

3x+4    = 1/2 (( 14x +7) - (7x+11))

Distribute

3x+4    = 1/2 ( 14x +7 - 7x-11)

Combine like terms

3x+4    = 1/2 ( 7x -4 )

Multiply each side by 2

6x +8 = 7x-4

Subtract 6x from each side

+8 = x-4

Add 4 to each side

12 =x

WVT = 3x+4

        = 3*12 +4

       = 36+4

       = 40

An animal shelter spends $3.00 per day to care for each cat and $6.50 per day to care for each dog. Amelia noticed that the shel
Ede4ka [16]

Answer:

There were 15 cats at the shelter on Friday.

Step-by-step explanation:

Cost of caring each cat = $3.00

Cost for caring each dog = $6.50

Total money spent by shelter = $84.00

Total Cats and Dogs in the shelter = 21

Let the number of cats in the shelter = k

So, the number of dogs in shelter =  21 -k

Also according to the question:

Total expenditure on cats + total expenditure on dogs = $84.00

or, k ($3.00) + (21-k)($6.50)  = $84.00

or, 3k + 136.5 - 6.5 k = 84

or, -3.5 k = 84 - 136.5 = -52.5

⇒3.5 k = 52.5  or k = 52.5/3.5 = 15

⇒  k = 15

Hence, the number of cats in the shelter was 15 on Friday.
