Answer:
Sin A = 0.38462
Step-by-step explanation:
From the trigonometric function,
Sin A =
................... 1
So that, applying the Pythagoras theorem to determine the value of hypotenuse,
=
+ 
=
+ 
= 576 + 100
= 676
Hyp = 
= 26
The hypotenuse of the triangle is 26.
Thus, from equation 1;
Sin A = 
Sin A = 0.38462
The given data are:
A function that:
The domain is the set of all real numbers
One x-intercept
The amplitude is 4
The y-intercept is (0,0)
From the choices, the functions containing "cosine" can be eliminated since the described function passes through (0,0). So, we are left with two choices:
y = -4sin (x) and y = 4sin (x)
Given the amplitude of 4, the answer must be y = 4 sin(x)
Answer:
Are there any options?
and it's not A)
so B)
Step-by-step explanation:
A) 25 N / 10 KG = A, A=2.5 M/S^2
b) 25 N / 5 M/S^2 = M, M = 5 KG
