Answer:
n = 18 cycles
Step-by-step explanation:
To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:
(1)
f: frequency of the oscillation of the current
t: time = 0.30s
The frequency is the number of cycles per second, that is, f = 60 cycles/s
You replace the values of f and t in the equation (1):
In 0.30s the current oscillates 18 times
Answer:
The translation is right 4 units and up 4 units
Step-by-step explanation:
we know that
The rule of the translation of the point V to V' is equal to
(x,y) ----> (x+4,y+4)
That means ----> The translation is right 4 units and up 4 units
Verify
V(-2,3) -----> V'(-2+4,3+4)
V(-2,3) -----> V'(2,7)
Is correct
Answer:
your selected answer is correct
Answer:
x = -1
y = -5
Step-by-step explanation:
9(2y+9) - 8y = 31
18y + 81 - 8y = 31
10y + 81 = 31
10y = -50
y = -5
2(-5) + 9 = x
-10 + 9 = x
-1 = x
<span>9x2 + 2 = 10x= x=2
</span>i dont know the first one
