Answer:
Question 1:
A) Parallelogram
B) Right Angled Triangle
Question 2:
Using parallelogram to use properties of parallel lines. To find whether a quadrilateral is parallelogram, first we will write it's coordinates. After writing coordinates, we find slope of each line by slope formula. After this , we compare the slope of equal lines through which we come to know whether they are parallel to eachother or not. After that, if two pairs of lines are parallel, then the given quadrilateral is a parallelogram.
S is less than 15
s<15
{s|s<15}
B is answer
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.
Answer:
-203
Step-by-step explanation:
We know that by formula
p^3 – q^3 = (p – q) (p^2 + pq + q^2 ) -------(1)
(p-q)^2 = p^2 -2pq +q^2 --------(2)
Solving eq(1)
(-7)^2 = p^2 -2(-10) +q^2
49 = 10 +p^2 + q^2
p^2 + q^2 = 39--------(3)
Given:
p-q = -7
pq = -10
Put all given values and eq(3) in eq(1)
p^3 - q^3 = (-7) (39-10)
p^3 - q^3 = (-7) (29)
p^3 - q^3 = -203
