Answer:
You need 75 points.
Step-by-step explanation:
Giving the following information:
Total number of points= 510 + 100= 610 (100%)
Actual number of points= 493
<u>First, we need to determine the number of points required to reach 93%:</u>
Points required= 610*0.93
Points required= 567.3 = 568
<u>Now, the points needed in the final exam:</u>
Difference of points= 568 - 493
Difference of points= 75 points
You need 75 points.
Answer:
f(t) = 101,234
Step-by-step explanation:
First, use FV formula to find the rate ;r given PV=101,234 and FV=104,271.02 and time= 1 year

104,271.02 = 101,234
Divide both sides by 101,234 to get;
104,271.02 / 101,234 = 1+r
1.03 = 1+r
1.03 -1 =r
therefore r= 0.03 or 3%
Next, to get the function of FV of estate after t years; f(t) ;
Plug in the 3% rate found above into the FV formula with PV being the current value of 101,234 and it becomes;
f(t) = 101,234
Answer:
Its either 4 or 4.6
Step-by-step explanation:
I used multiplication.
His rate = d/t because d=rt
So r = 5/2 = 2.5 mi/hr
So d = 5/2•t
