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.

<u>Question 1:</u>

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

<u>Question 2:</u>

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

Keywords: Explicit formula, arithmetic sequence

Select the correct answer1 - quadratic, linear, exponential2 - 1.5, 18, 16, 123 - 16, 12, 20, 184 - 18, 6, 20, 12
Alexxandr [17]

1 - The equation is:

p(x)=-0.5x^2+6x

Since it has no variable on exponents and it has a term with x to the second power, this is a quadratic function.

2 - <em>x</em> represents the length of the tomato patch, so if we want the area of the bell pepper patch, we can input x = 8 into the function:

\begin{gathered} p(8)=-0.5\cdot8^2+6\cdot8 \\ p(8)=-0.5\cdot64+48 \\ p(8)=-32+48 \\ p(8)=16 \end{gathered}

Thus, the area is 16 square feet.

3 - Since the leading coefficient is negative, the vertex of the parabola gives the maximum value for the function.

The <em>x</em> value of the vertex is:

\begin{gathered} ax^2+bx+c \\ x_v=-\frac{b}{2a} \end{gathered}

So, in this case:

x_v=-\frac{6}{2\cdot(-0.5)}=-\frac{6}{-1}=6

And to find the value for the area, we need to input that into the function:

\begin{gathered} p(6)=-0.5\cdot6^2+6\cdot6 \\ p(6)=-0.5\cdot36+36 \\ p(6)=-18+36 \\ p(6)=18 \end{gathered}

Thus, the maximum area is 18 square feet.

4 - The value for the length of the tomato patch is just the corresponding <em>x</em> for this maximum, which we calculated as the vertex <em>x</em>:

x_v=6

Thus, the length of the tomato patch for this maximum value is 6 feet.

Use the formula to find the amount, A= P(1+rt), to find the indicated quantity A=$672; P=600; R=12%; T=? T=year(s)
IrinaVladis [17]
A=P(1+rt)
A=672, P=600, R=0.12
672=600(1+0.12t)
1+0.12t=672/600=1.12
0.12t=0.12
t=0.12/.12=1
Answer: T=1 year
