Answer:

the average rate of change rc is 13 , 12.1 and 12.01 for h=1 , 0.1 and 0.01 respectively

Step-by-step explanation:

for

R(t) = 30*t − 3*t² ; t = 3

the average rate of change of R(t) over the time interval [t, t + h] is

rc= [R(t+h)-R(t)] / [(t+h) -t) = [R(t+h)-R(t)] /h = 1/h * [ 30*(t+h) − 3*(t+h)²  - (  30*t − 3*t² ) ] =  (1/h) * ( 30*h - (3*t² + 6*t*h + t²) +3*t² ) = 30 - 6*t + h

then

rc= 30 - 6*t + h

for t=3 and h=1

rc= 30 - 6*3 + 1 = 13

for t=3 and h=0.1

rc= 30 - 6*3 + 0.1 = 12.1

for t=3 and h=0.01

rc= 30 - 6*3 + 0.01 = 12.01

for t=3 and h=0.001

rc= 30 - 6*3 + 0.01 = 12.001

when h goes smaller , the average rate of change gets closer to the instantaneous rate of change of R(t) in t=3 (the derivative of R in t=3) , that is

R'(t)= 30 - 6*t

A mother is three times as old as her daughter, and the sum of their ages
garri49 [273]

Answer:

33

Step-by-step explanation:

If m = Mother's age and d = daughter's age, we can make the following equations

m = 3d

m + d = 44

Now, using substitution, we can substitute m for 3d in the second equation:

3d + d = 44, 4d = 44, d = 11

Then, we can plug d into the first equation: m = 3(11) = 33

Chloe and tino have a combined age of 48. three years ago chloe was double the age tino is now. find tinos age
jeka94

As  given Chole and Tinos age , the present age of Tino is equal to 15 years.

As given,

Let x and y be the present age of Chole and Tino. respectively.

Combined age = 48

Given condition,

x + y = 48 _______(1)

Three years ago

x - 3 = 2y

⇒x =2y +3 _______(2)

Substitute the value of x in (1),

2y+3 +y =48

⇒ 3y = 45

⇒ y = 15years

Therefore , as given Chole and Tinos age , the present age of Tino is equal to 15 years.
