Answer:
25000m/s
Step-by-step explanation:
The following formula is used to calculate the speed or velocity of a wave.
V = f * w
Where V is the velocity (m/s)
f is the frequency (hz)
w is the wavelength (m)
First, determine the frequency.
Calculate the frequency of the wave.
Next, determine the wavelength.
Calculate the wavelength of the wave.
Finally, calculate the wave speed.
Using the formula above, calculate the wave speed.
Answer:-24
Step-by-step explanation:
6+(-5-7) ➗ 2-8(3)
6-12 ➗ 2-24
6-6-24
0-24=-24
Answer:
A
Step-by-step explanation:
A) J = (3/8)*(5/15 -6/15) = (3/8)*(-1/15) = (1/8)*(-1/5) = -1/40
.. K = (3/4)*(4/6 -5/6) = (3/4)*(-1/6) = (1/4)*(-1/2) = -1/8
B) (-1/40) +(-1/8) = -1/40 -5/40 = -6/40 = -3/20
C) The opposite of -3/20 is 3/20
D) Real world: I'm answering Brainly.com questions and one asks the opposite of -3/20.
This shows that both functions have the same y-intercept
<h3>Polynomial and exponential functions</h3>
Given the following functions as shown:
f(x) = -x^2 + 2x + 1
g(x) = 2^x
The y-intercept occurs at x = 0
For f(x) = -x^2 + 2x + 1
f(0) = -0^2 + 2(0) + 1
f(0) = 1
For the g(x), the y intercept is caculated as:
g(0) = 2^0
g(0) = 1
This shows that both functions have the same y-intercept
