Answer: C
y=-5cos(x) is the graphed equation. Cos(x) starts at (0,0) and one period is 2pi or 6.28 and by cos(x) multiplied by -5 starts the cosine wave at (0,-5) and thus corresponds to the graphed equation shown.

Answer:
see explanation
Step-by-step explanation:
To find the second and fifth terms substitute n = 2 and n = 5 into the rule, that is
(a)
= 3(2)² - 1 = (3 × 4) - 1 = 12 - 1 = 11
(b)
= 3(5)² - 1 = (3 × 25) - 1 = 75 - 1 = 74
Thus the second term is 11 and the fifth term is 74
Answer:
(a) t = 1.6766
Step-by-step explanation:
n = 50
degree of freedom = n - 1 = 50 - 1 = 49
confidence level = 90%
The critical value corresponding to 90% confidence level and 49 degrees of freedom is obtained by interpolating between 48 and 50 degrees of freedom (df)
Let the critical value at 49 df be y
dof. critical value
48. 1.677
49. y
50. 1.676
(49 - 48)/(50 - 48) = (y - 1.677)/(1.676 - 1.677)
0.5 × -1×10^-3 = y - 1.677
y - 1.677 = -5×10^-4
y = -5×10^-4 + 1.677 = 1.6765
The closest option is (a)
The answer is Ten million.
Answer : y = -2x - 4
All you have to do is put y on one side and the 2x on the other side, just make sure to make it negative since you are subtracting it to go on the other side
