The other dude most likely attached a virus

The answer is 0.56464247339


Across from the right angle is the hypotenuse

Across from where the two long sides end is the opposite

And the other side is the adjacent

Sin (opposite/hypotenuse) cos(adjacent/hypotenuse) tan (opposite/adjacent)

What is a1 for the geometric sequence for which a8= -3584 and a3 = 112 ?
Kazeer [188]

Answer:

The first term is 28.

Step-by-step explanation:

Given: 8th term of Geometric sequence , a_8=-3584

and 3rd term of Geometric Sequence, a_3=112

We have to find First term of given geometric Sequence.

Let a be the first term of geometric sequence.

We know that,

a_n=ar^{n-1}

So,

\frac{a_8}{a_3}=\frac{ar^{8-1}}{ar^{3-1}}=\frac{-3584}{112}

\frac{r^{7}}{r^{2}}=-32

r^5=-32

r=-2

So, 3rd term = 112

a × (-2)² = 112

a = 112 / 4

a = 28

Therefore, The first term is 28.

Can someone please give me the answers to these 2 will add 40 points
Zielflug [23.3K]

Answer:

<h2>Q1. x = 17.1; y = 5.6</h2><h2>Q2. x = 9.7; y = 24.1</h2>

Step-by-step explanation:

Use sine and cosine.

sine=\dfrac{opposite}{hypotenuse}

cosine=\dfrac{adjacent}{hypotenuse}

Q8.

We have:

opposite=y\\\\adjacent=x\\\\hypotenuse=18\\\\\alpha=18^o\\\\\sin18^o\approx0.309\\\\\cos18^o\approx0.9511

Substitute:

\dfrac{y}{18}=0.309            <em>   multiply both sides by 18</em>

y=5.562\to y\approx5.6

\dfrac{x}{0.9511}=18             <em>multiply both sides by 0.9511</em>

x=17.1198\to x\approx17.1

Q9.

We have:

opposite=y\\\\adjacent=x\\\\hypotenuse=26\\\\\alpha=68^o\\\\\sin68^o\approx0.9272\\\\\cos68^o\approx0.3746

Substitute:

\dfrac{y}{26}=0.9272             <em>multiply both sides by 26</em>

y=24.1072\to y\approx24.1

\dfrac{x}{26}=0.3746          <em>multiply both sides by 26</em>

x=9.7396\to x\approx9.7
