Weird. I think you just need to look if the point falls on the shaded area. But only (-5,5) does ...

Simple interest=prt
=688.88 (.0925)(1)
=63.72

Balance=investment + interest earned
=688.88+63.72=$752.60

Solve for the varible y: 2y+4=6

sattari [20]

2y+4=6

First, subtract the 4 from both sides:
2y+4-4=6-4
Simplify:
2y=2
Divide both sides by 2:
y=1

Given:An = [6 n/(-4 n + 9)]For both of the following answer blanks, decide whether the given sequence or series is convergent or

Mrrafil [7]

Answer:

The sequence is convergent and the serie is divergent.

Step-by-step explanation:

Sequence:

We calculate the limit when n tends to infinity to see if it is convergent or divergent:

$\lim_{n \to \infty} \frac{6n}{-4n+9} = \frac{6}{-4} = \frac{-3}{2} \neq 0$ then, the sequence is convergent.

Serie:

$\sum_{n=1}^{\infty} (\frac{6n}{-4n+9})$ . To know if it converges we are going to use the limit test:

$\lim_{n \to \infty} a_n$ . If this limit is non equal to 0 the serie diverges.

$\lim_{n \to \infty} \frac{6n}{-4n+9} = \frac{6}{-4} = \frac{-3}{2} \neq 0$ , then the serie diverges.

If cos theta=-2/3, which of the following are possible (Help asap)

alexgriva [62]

Answer:

The correct option is B) $sin\theta=\frac{\sqrt{5}}{3}$ and $tan\theta=\frac{\sqrt{5}}{2}$

Step-by-step explanation:

given $cos\theta=-\frac{2}{3}$

Since, $cos\theta=\frac{base}{hypoteneous}$

it means prependicular of right angled triangle can be calculated by pythagoras theorem as:

base² + prependicular² = hypoteneous²

2² + prependicular² = 3²

4 + prependicular² = 9

prependicular² = 9 - 4

prependicular² = 5

prependicular = √5

Since, $sin\theta=\frac{prependicular}{hypoteneous}$

$sin\theta=\frac{\sqrt{5}}{3}$

Since, $tan\theta=\frac{prependicular}{base}$

$tan\theta=\frac{\sqrt{5}}{2}$

Hence, the correct option is B) $sin\theta=\frac{\sqrt{5}}{3}$ and $tan\theta=\frac{\sqrt{5}}{2}$
