Suppose the depth of the diver is d at time time t, rate is given by r=12 1/3 ft/ min. The equation representing the depth of the diver at time t will be:
f(t)=200-(12 1/3)t
Therefore the depth of the diver after t=4.5 min will be:
f(4.5)=200-(12 1/3)*4.5
f(4.5)=200-55.5
f(4.5)=144.5 ft
This means that after 4.5 minutes the diver will be 144.5 ft deep.
The value of angle a will be 33°.
It should be noted that when we've parallel lines, then the angles will be equal. In this case, the value of angle a will be equal to that of angle b and this will be:
5x + 8 = 8x - 7.
Collect like terms .
8x - 5x = 8 + 7
3x = 15
Divide both side by 3
3x/3 = 15/3
x = 5
Therefore, the value of angle a will be:
= 5x + 8
= 5(5) + 8
= 25° + 8°
= 33°
The measure of angle a is 33°.

Answer:
Absolute error = 39
Percent Error = 6.10%
Step-by-step explanation:
Actual value = 639 pounds
Observed Value = 600 pounds
The formula to find absolute error is:
Absolute Error = Actual value - Observed Value
= 639 - 600
= 39
The formula to find Percent error is:
Percent Error = (Actual value - Observed Value / Actual value)*100
= (639 - 600/639)*100
= 6.10%
