Answer:

$204.11

Step-by-step explanation:

He is paying 70% of the original cost, so he is paying

269.99(0.7) = $188.99

He has to pay 8% sales tax on that discount price, so he pays

$188.99(0.08) = $15.12 tax

for a total of

$188.99 + $15.12 = $204.11

Use the information to answer the following question.

trasher [3.6K]

Answer:

D is the answer

Step-by-step explanation:

For a: g(x) = 1 when x = 1, for f(x) 1^2 - 2(1) + 2 = 1, a is true.

For b: Both functions do have all real numbers for their domain, b is true

For c: the y-intercept of g(x) is x = 0, for f(x), it is 0^2 - 2(0) + 2 = 2, c is true

For d: g(3) = 7, f(3) = 3^2 - 2(3) + 2 = 5, d is false.

An object has a Mass of 5 kg what force is needed to accelerate it at 6/ms2

Ostrovityanka [42]

Answer:

Step-by-step explanation:

It can be solved by applying formula for Force.

Force = mass * acceleration

Unit of force is N(newton)

one newton is the force applied on body when a body of mass one kg, accelerate at 1/ms^2 under the influence of force.

________________________

given

Mass = 5 kg

acceleration = 6/ms2

plug in the value of mass and acceleration in formula for for we have

$force = mass * acceleration\\=>force = 5 * 6\\=>force = 30$

Thus 30 N(newton) force is required to accelerate at 6m/s^2
