No, there are lots of quadrilaterals. <span>Examples of other quadrilaterals
are rhombus, kite, trapezoid, parallelogram etc</span>
Can someone please help me answer this problem
Part a: i got 15 outcomes
part b: 4/15, about 26.7%
part c: 1/15, about 6.67%
hope this helps you :,)
Integrate both sides with respect to <em>x</em> :

On the right side, integrate by parts with


Then

Integrate both sides with respect to <em>x</em> by parts again, this time with


Then

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.
