for parallelograms:
area = b(h)
so basically, the length times the height. just like how you would find the area of a square.
perimeter: just add all of the sides together.
for triangles:
area = 1/2(b) x h
so half the length multiplied by the height. for example, if the length was 4, you have to use half of that. so that means 2 times whatever the height is.
perimeter: again, just add all three sides together
F(1) = 45
f(n) = f(n-1) * 4/5
Step-by-step explanation:
f(n) = 45 x (4/5)ⁿ⁻¹
f(1) = 45 x (4/5)¹⁻¹ = 45 x (4/5)⁰ = 45 x 1 = 45
f (n-1) = 45 x (4/5)ⁿ⁻¹⁻¹ = 45 x (4/5)ⁿ⁻²
f(n) = f(n-1) * (4/5)¹ = 45 x (4/5) ⁿ⁻²⁺¹ = 45 x (4/5)ⁿ⁻¹
Answer:yk i’m looking for the answer too, i can’t find it
Step-by-step explanation:
Answer:
4800$
Step-by-step explanation:
1 day = 600
7 years = 600 x 2 = 1200$
14 years = 1200 x 2 = 2400$
21 years = 2400 x 2 = 4800$
