Answer:
$0.30 per ounce
Step-by-step explanation:
16 ounces per pound
16 x 2 = 32 ounces per 2 pounds
9.60/32 = $0.30 per ounce
Answer:
y=4/5x-5
Step-by-step explanation:
to find the slope intercept form (y=mx+b) we must find the slope(m) first. We take the two points given and use the slope formula (y2-y1/x2-x1) take the point (0,-5) as (x1,y1) and the point (5,-1) as (x2,y2).Using the slope formula {-1-(-5)/5-0}. We get the slope equal to 4/5. Now we have y= 4/5x+b.To find b we must choose one point from the given and substitute x and y in the formula we have(y=4/5x+b). I chose (0,-5) so substituting that, (-5=4/5(0)+b), and to finally get b=-5.Now substitute b in the equation y=4/5x+b to get y=4/5x-5.
Plug in 6 for x
3(6) + 4 = 22
The value if 22, or you can write it like:
f(6) = 22
Answer:
y-int= (0,2.5)
x-int= (3.5,0)
Step-by-step explanation:
Answer:
a) see attached
b) period = 1/f ≈ 3.822 ms
Step-by-step explanation:
Apparently the pressure formula is ...
__
a) A graph of this for f=261.63 is shown in the attachment.
__
b) The period is the time T required to change the sine function argument by 2π:
2πfT = 2π
T = 1/f . . . . . . divide by 2πf
The period is the reciprocal of the frequency.
The period of the tone is 1/(261.63 Hz) ≈ 3.822·10^-3 s
