7.(WorkPad, must figure out yourself)
8. (essay question, must figure out yourself)
----------->Number 7
y = 4 Since there is no slope,
the input will just be the same as the output
----------->Number 8
a) At the end of 3 years the amount in the account = Principal + Interest
Amount = 4000 + 960 = 4960
Amount at the end of 3 years = $4960
b) Formula for Rate , R = 100I/(PT)
Where I = Interest = 960, P = Principal = 4000, T= Time = 3 years
R = (100 × 960) / ( 4000 × 3)
R = 8
Rate, R = 8% per annum.
c) If the rate was 1% more, R = 8 + 1 = 9% per annum
Interest, I = PRT/100
Interest, I = 4000 × 9 × 3 /100 = 1080
Amount in her account would have been = $4000 + $1080 = $5080
Amount more = $5080 - $4960 = $120
She would have had $120 more should the rate were 1% greater
@Mrs. Elana acting like you're a teacher lol. If you were a teacher you'd know the difference between "your" and "you're".
Cutie pie is 100% correct
1. graph iv
2. b, left side is 25 and right side is 14
3. 105.00
4. b
5. 643.15
6. plan b, 1040.00
7. The graph shows a zero slope since the equation of this graph is y = 4. No matter what the input is, it will just give you the same output. The input doesn't really give a care to the output because the output is just the same all through out.
Thank you Cutie Pie you are the best
could some one plz put the last few questions plz i need them
thanks cutie pie!
