There is little context to go off of but the answer should be variable
Answer:
Coefficients:
7g = 7
2t = 2
Step-by-step explanation:
Coefficients are the multiplicative numbers that preceed the variable. If a variable has no coefficient written, then that coefficient is 1 (symbol carried over).
Answer:
the both lines are perpendicular so their slope product is -1
so slope of 2nd perpendicular line is 3
so equ is y-2=3(x-4) so y=3x-10
Answer:
b is 10
Step-by-step explanation:
Answer:
The apparent displacement of the coin is 2.5 cm
Step-by-step explanation:
Mathematically;
shift = real depth * (1-1/refractive index)
From the question;
real depth = 7.5 cm and refractive index = 1.5
Thus, substituting this, we have;
shift = 7.5 * (1-1/1.5)
shift = 7.5 * (1/3)
shift = 7.5/3 = 2.5 cm
