Answer:

31.5

Step-by-step explanation:

Area of a rectangle = lw

Substitute: 7*3 = 21

Area of a Triangle = 1/2*bh

Substitute: 1/2*(3)(7) = 10.5

Area = 21 + 10.5 = 31.5

Answer:

B. 600,000 (1.15)^{n-1}

Step-by-step explanation:

The n-th term of a geometric sequence with initial value a and common ratio r can be determined by multiplying the first term of the sequence (i.e. initial value a) by r^{n-1}.

The first term (i.e. initial value a) is 600,000.

The common ratio r can be calculated by dividing any two consecutive terms in the sequence:

r = 690,000/600,000 = 1.15 or r = 793,500/690,000 = 1.15

Thus, we get the answer:

the explicit rule that can be used to determine the value of the art collection n years after that is 600,000 (1.15)^{n-1}

Given a sequence is defined by the explicit definition tn=n^2+n.... (questions attached)

s2008m [1.1K]

Question 1: The correct answer is Option 3: 20

Question 2: The correct answer is Option 3: 27

Step-by-step explanation:

We put the term number as value of n in explicit formula to find the term.

Question 1:

Given

$t_n=n^2+n$

To find t4, we will put t=4 in explicit formula

$t_4=(4)^2+4\\t_4=16+4\\t_4=20$

The correct answer is Option 3: 20

Question 2:

Given, the explicit formula

$t_n=2^n-n$

We have to find the 5th term, putting n=5 in the explicit formula

$t_5=2^5-5\\=32-5\\=27$

The correct answer is Option 3: 27
