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}

p is inversely proportional to 3q-1. The difference in the values of p when q = 1 and q=2 respectively is 3. Find the value of p
Vsevolod [243]

Step-by-step explanation:

3q - 1 = 3(1) - 1 = 2

3q -1 = 3(2)- 1= 5

10/p = 2 10/p = 5

p= 5 p= 2 (5-2=3, so 10/p is correct)

q=5, 3(5) -1 = 14

10/p = 14

p = 0.71??
