First 4 terms for 5 - 2n
vlabodo [156]

Answer:

3 , 1 , -1 , -3

Step-by-step explanation:

5 - 2n

n = 1 ;  5 - 2n = 5 - 2*1 = 5 - 2 = 3

n = 2;  5 - 2n = 5 - 2*2 = 5 - 4 = 1

n = 3;  5 - 2n = 5 - 2*3 = 5 - 6 = -1

n = 4;  5 -2n = 5 - 2*4 = 5 - 8 = -3

First 4 terms are :  3 , 1 , -1 , -3

Given the ordered pair P, determine the requested sin, cos, or tan of angle . P(4, 5) sin = (4√41)/41 (5√41)/41 4/5 5/4 what is
Viefleur [7K]
Ok <span>One side would have a length of 4, another side would have a length of 5, and then we can use the Pythagorean Theorem to find the length of the hypotenuse. a^2 + b^2 = c^2 </span>

<span>a=4; b=5; </span>

<span>4^2 + 5^2 = c^2 </span>
<span>16 + 25 = c^2 </span>
<span>41 = c^2 </span>
<span>c = √41 </span>

<span>Therefore, the hypotenuse has a length of √41. </span>

<span>To find the sinθ, you take the opposite over the hypotenuse. </span>

<span>Remember when you drew out the triangle? θ is the angle connected to the origin. The opposite side is b, which is 5. </span>

<span>Your answer is 5/√41. </span>

<span>This answer must be simplified since there is a radical in the denominator. To simplify, you can just multiply the numerator and the denominator by √41/√41 (since this is equivalent to 1). </span>

<span>This gives you the answer
