G(n)=3n^3-5 h(n)=2n-5 find(g+h)(2)

dlinn [17]

g(n) = 3n³ - 5 h(n) = 2n - 5 (g + h)(2) = g(2) + h(2)

g(2) = 3(2)³ - 5 = 3(8) - 5 = 24 - 5 = 19

h(2) = 2(2) - 5 = 4 - 5 = -1

g(2) + h(2) = 19 + -1 = 19 - 1 = 18

Answer: 18

PLEASE HELP, BEST ANSWER GETS BRAINIEST Each letter of the word "RESPONSIBLE" is written on a separate slip of paper and placed

Simora [160]

Answer:

1) 2/11

2) 2/121

Step-by-step explanation:

1. Because there are 2 E's, you have to chances out of your 11 changes, thus why the fraction 2/11 is the solution.

2. You know that 2/11 is the first fraction, so now find R. R has a 1/11 chance of getting chosen, so you multiply 2/11 and 1/11 to get 2/121.

While traveling in a car, the centrifugal force a passenger experiences as the car drives in a circle varies jointly as the mass

rjkz [21]

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,

$k = \frac{F_{1} }{m_{1}v_{1} ^{2} } = \frac{F_{2} }{m_{2}v_{2} ^{2} }\\ F_{2} = F_{1} \frac{m_{2} }{m_{1} }(\frac{v_{2} }{v_{1} }) ^{2} \\F_{2} = 226.8\frac{90 }{70 }(\frac{40 }{60 }) ^{2}\\F_{2} = 129.6 newtons$
