Answer:
x=20
Step-by-step explanation:
Well just cross multiply if its easier
x(3)=3x
12*5=60
60=3x
x=20
Take the second equation already set to y and substitute it into the first equation for y...
3x + (6 - 4x) = 1 ... now we simplify
3x + 6 - 4x = 1 .....now combine like terms
-x + 6 = 1 .....
Answer:
The correct option is;
d(t) = 6·cos(π/3·t) + 28
Step-by-step explanation:
The general form of a cosine function is given as follows;
y = A·cos(B·x - C) + D
Where;
A = The amplitude = The distance from the peak to the midline = 1/2×(Maximum - minimum)
The amplitude = 1/2 × (34 - 22) = 6 inches
B = 2·π/P = 2·π/6 = π/3
P = The period = 6 seconds
C/B = The phase shift
D = The midline = Minimum + Amplitude = 22 + 6 = 28 inches
x = The independent variable
Therefore, to model the function of the wave can be given as follows;
d(t) = 6·cos(π/3·t) + 28
All of those numbers have nothing but ones digits, that is, they're all single digits. j=4, k=5, and n=6.
Answer:
The answer is 8/25. This is because 32% is equal to 32/100, when you simplify this it equals 8/25.
