Answer:

Graph A

Step-by-step explanation:

For a relation to be said to be a function, each x-value must have exactly one y-value assigned to it. That is, no domain value has two different range value assigned to it.

Therefore, graph A is a function, because exactly 1 range value is assigned to each domain value.

Consider the sequence 10, 2..

romanna [79]

Answer: see below

Step-by-step explanation:

1) 10, 2, 1.2, 1.12, 1.112, 1.1112

$t_n=\dfrac{t_{n-1}}{10}+1$

t₁ = 10

t₂ = 10/10 + 1 = 2

t₃ = 2/10 + 1 = 1.2

t₄ = 1.2/10 + 1 = 1.12

t₅ = 1.12/10 + 1 = 1.112

t₆ = 1.112/10 + 1 = 1.1112

2) 10, 2, -2, -4, -5, -5.5, ...

$t_n=\dfrac{t_{n-1}}{2}-3$

t₁ = 10

t₂ = 10/2 - 3 = 2

t₃ = 2/2 - 3 = -2

t₄ = -2/2 - 3 = -4

t₅ = -4/2 - 3 = -5

t₆ = -5/2 - 3 = -5.5

If an investment of $3000 grows to $4432.37 in eight years with interest compounded annually , what is the interest rate?

melamori03 [73]

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\to &\$4432.37\\
P=\textit{original amount deposited}\to &\$3000\\
r=rate\to r\%\to \frac{r}{100}\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{annually, thus once}
\end{array}\to &1\\
t=years\to &8
\end{cases}$

$\bf 4432.37=3000\left(1+\frac{r}{1}\right)^{1\cdot 8}\implies \cfrac{4432.37}{3000}=(1+r)^8
\\\\\\
\sqrt[8]{\cfrac{4432.37}{3000}}=1+r\implies \sqrt[8]{\cfrac{4432.37}{3000}}-1=r
\\\\\\
0.0500001086\approx r\qquad\qquad\cfrac{r\%}{100}\approx 0.0500001086
\\\\\\
r\%\approx 100\cdot 0.0500001086\implies r=\stackrel{\%}{5}$

Consider the numbers 4 and √5. Which operation(s) will result in an irrational number?

tekilochka [14]

Answer: D (both the sum and the product).

Step-by-step explanation:

Let's add: 4 + sqrt5 will still seem irrational.

Let's multiply: 4*sqrt5 = 4sqrt5, which is irrational.
