(1.5)*(2)*(10^(-3)*(10^4) = 3*10^(-3+4) = 3*10^1 = 3*10 = 30 (answer)
Answer:
Step-by-step explanation:
We want to find equation of a circle with center (-4,6) and radius 9cm.
The equation of a circle with center (h,k) and radius 
units is given by;
We substitute the radius and the center to obtain;
The required equation is:
Answer:
64+77=141
Step-by-step explanation:
The whole number times the denominator plus the numerator. Then, add and do the same thing again with the other number and you get 64 and 77 then add and you get 141
Answer:
total profit gained = 20%
Step-by-step explanation:
profit = SP - CP = 18 - 15 = 3 naira
total profit percentage =
- ( profit / CP ) × 100

- 20%
hence her total percentage gain was 20%
Answer:
-cos^4(x)
Step-by-step explanation:
Step 1: Use the Pythagorean identity : 1=cos^2(x) + sin^2(x)
1-sin^2(x) = cos^2(x)
-1+sin^2(x) = -cos^2(x)
cos^2(x) (-cos^2(x))
Step 2: Factor out common terms cos^2(x)
cos^2(x) (sin^2(x)-1)
Ans: -cos^4(x)
