Answer:
3.84x10^14Hz
Step-by-step explanation:
From the question, the following were obtained:
Velocity = 3x10^8m/s
Wavelength = 7.80x10^-7
Frequency =?
Frequency = Velocity /wavelength
Frequency = 3x10^8/7.80x10^-7
Frequency = 3.84x10^14Hz
Answer:
see explanation
Step-by-step explanation:
Find AC
AC = AD + DC = 3y + 4x
(i)
AE = 
AC = (3y + 4x) = 
y + 2x
(ii)
CB = - AD = - 3y
Answer:
Where the grid?
Step-by-step explanation:
Answer: figure 1). x = 36 2). x = 123
Explanation:
Figure 1:
Angle x = angle 1
And angle 4 = 4x
Angle 4 + angle 1 = 180
4x + x = 180
5x = 180
x = 36
Figure 2:
Angle 1 = 68 degree
Angle 2 = 55 degree
Find angle 3:
180 - (68 + 55)
= 180 - 123
= 57 degree
But angle 3 = angle 4 = 57 degree
But: angle 4 + x = 180
57 + x = 180
x = 180 - 57
x = 123
The range of the function given the domain x > -2 is; Range; y < -8.
<h3>What is the range of the function?</h3>
The range of a function is the set of all possible outcomes of the function. In this scenario, since the domain of the function is given as X > -2. It follows from the function that at all times, the range of the function is given by; y < -8 from; y < 5(-2) +2; y< -8.
