Based on the pattern, what are the next two terms of the sequence? 9, 95, 925, 9125 , 9625, ... 9630, 93130 93125,915625 9630.96
likoan [24]

It appears that the digit 9 is prepended to each term of the sequence 5^(n-1).

The next two terms will be 5^5 and 5^6, each with 9 prepended: 93125 and 915625.

If 0 is an angle in standard position and its terminal side passes through the point
liraira [26]

Answer:

\frac {  5\sqrt{21} }{ - 7}

Step-by-step explanation:

Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r

{7}^{2}  +  {24}^{2}  =  {r}^{2}

49+576=

{c}^{2}

525=c^2

\sqrt{525}  = 5 \sqrt{21}

So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals

\frac{x}{r}

cos=

\frac{ - 7}{5 \sqrt{21} }

then we find secant which is the reciprocal of cos so we flip the numbers and that equals

\frac{5 \sqrt{21} }{ - 7}
