What is the nth term for 7,11,15,19
Murrr4er [49]

Answer:

a_{n} = 4n + 3

Step-by-step explanation:

Note there is a common difference d between consecutive terms, that is

d = 11 - 7 = 15 - 11 = 19 - 15 = 4

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 4, thus

a_{n} = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

vovikov84 [41]

Answer:

D. 25% decrease

Step-by-step explanation:

Since it's clear that they read less books to find how much it decreased we multiply 100 with 15 then divide it by 20

100 × 15 ÷ 20 = 75 this result shows a 25% decrease.

Pls help<br> Enter the equation for the graph.
prisoha [69]

Answer:

y=[1]cos([\frac{2\pi }{3}]x)

Step-by-step explanation:

Looking at the graph, we can see the domain to be from (0 , 2π).

Now we have to find one period that corresponds to cos(x).

The half-period of cos(x) for this graph appears to be pi/3 and adding another pi/3 gets us 2pi/3 to be our cosine period.

b = 2pi/3

a is the same range as cos(x). Range: (0,0)

y = [a] * cos ([b]*x)

y = [1] * cos([2pi/3]x)
