Answer:
Sound requires a material medium to travel , the sound through each medium through its molecules and particles present in it .Sound travels with some speed and it's speed depends upon the nature of the medium through which it travels i.e. upon density and transparently. Speed of increases with the increase in density and decreases with the increases in temperature . Speed if sound us maximum for solid then for liquid and minimum in gases because of it's large intermolecular spaces and low density.
The equation is already is slope intercept form where you can easily point out the gradient, or the slope, and the y intercept.
y=mx+b where m is the gradient, and b is the y intercept.
Since there is no m, the gradient is 1.
The y intercept had x=0 and y=b
b in this case is 6
the y intercept= (0,6)
Answer:
18
Step-by-step explanation:
Since he does 90 cars-----5 days
x cars--------1 day
we multiply 90 by 1 then over 5
A² + b² = c²
5² + 8² = x²
x² = 25 + 64
x² = 89
x = √89
x = 9.43
Answer:
option b
Step-by-step explanation:
the denominator is in the surd form, so it must be rationalized
