Answer:
A- 129.6 N
Step-by-step explanation:
Since the centrifugal force on the passenger, F varies jointly as the mass of the passenger, m and the square of the speed of the car,v. In mathematical notation, F ∝ mv² ⇒ F = kmv².
If F₁ = 226.8 Newtons, m₁ = 70 kilograms and speed v₁ = 60 kilometers per hour. From F= kmv², k = F/mv² the proportionality constant. If F₂ is the force on the passenger of mass m₂ = 90 kilograms and speed of car ,v₂ = 40 kilometers per hour. Then,
Answer:
Interest earned= $6,060
Step-by-step explanation:
Giving the following formula:
Principal (P)= $12,625
Interest (r)= 4%= 0.04
Period of time (t)= 12 years
<u>To calculate the interest earned after twelve years, we need to use the following formula:</u>
I= P*r*t
I= (12,625*0.04*12)
I= $6,060
Interest earned= $6,060
Answer:
D
Step-by-step explanation:
Multiply by 3
4 x 3 = 12
9 x 3 = 27
Step-by-step explanation:
by deleting
9y = -9
y = -1
6x - 4 = -10
6x = -6 then x = -1
C, because the graph titles.
