Answer: C) Changing one or more properties of a sine wave in response to data.
Step-by-step explanation:
Modulation is primarily used in telecommunications sector. It the process by which data is transmitted via electrical signals. It is the process of imposing an input signal on to a wave carrier. It is the pillar of data communication that enables the use information carriers of signals that are electrical and optical. Altering the carrier/ periodic waveform results in Modulation. The amplitude frequency and phase are conveyed. There are different types of Modulation which includes: amplitude Modulation, frequency Modulation, and phase Modulation.
$4.55 Add 5.95 and 9.76. You should get 15.45. Then you do 20-15.45=4.55
Answer:
I think its 71
Step-by-step explanation:
Well the average between -3 -2 and -1 seems to be -2, so all i do is 95-24 and you get 71, either that or 65. I highly think its 71 though
Answer:
(a) The price for a revenue of $18,750 is $239.2.
(b) They sold 710 colonial houses and 2130 ranch houses
Step-by-step explanation:
(a) If the weekly revenue is defined as
![r=2p^2+400p](https://tex.z-dn.net/?f=r%3D2p%5E2%2B400p)
then the price must be calculated as:
![r=2p^2+400p=18750\\\\2p^2+400p-18750=0](https://tex.z-dn.net/?f=r%3D2p%5E2%2B400p%3D18750%5C%5C%5C%5C2p%5E2%2B400p-18750%3D0)
The roots of this function are
![x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}=\frac{-400 \pm \sqrt{400^2-4*2*(-18750)}}{2*2}\\ \\x=\frac{-400 \pm 556.78}{4}\\ \\x_1=-39.2\\x_2=239.2](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5Cpm%20%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D%3D%5Cfrac%7B-400%20%5Cpm%20%5Csqrt%7B400%5E2-4%2A2%2A%28-18750%29%7D%7D%7B2%2A2%7D%5C%5C%20%20%5C%5Cx%3D%5Cfrac%7B-400%20%5Cpm%20556.78%7D%7B4%7D%5C%5C%20%5C%5Cx_1%3D-39.2%5C%5Cx_2%3D239.2)
The first root is negative, so it is not a real solution. So the second root is the answer.
The price for a revenue of $18,750 is $239.2.
(b) Last year they sold three times as many ranch models (Hr) as they did colonial models (Hc):
![H_r=3*H_c](https://tex.z-dn.net/?f=H_r%3D3%2AH_c)
The total amount of houses sold (colonial + ranch) is 2840
![H_c+H_r=2840\\H_c+3*H_c=2840\\4*H_c=2840\\H_c=2840/4=710\\\\H_r = 3*H_c=3*710=2130](https://tex.z-dn.net/?f=H_c%2BH_r%3D2840%5C%5CH_c%2B3%2AH_c%3D2840%5C%5C4%2AH_c%3D2840%5C%5CH_c%3D2840%2F4%3D710%5C%5C%5C%5CH_r%20%3D%203%2AH_c%3D3%2A710%3D2130)
Answer: You plug in a value for one of the variables
Step-by-step explanation: For example f(x)=2x+2
x=6 2(6) +2=14
