Answer:
Here we have the function:
S(t) = 500 - 400*t^(-1)
Then the rate of change at the value t, will be:
S'(t) = dS(t)/dt
This differentiation will be:
S'(t) = -400/t^2
Then:
a) the rate of change at t = 1 is:
S'(1) = -400/1^2 = -400
The rate of change after one year is -400
b) t = 10
S'(10) = -400/10^2 = -400/100 = -4
The rate of change after 10 years is -4, it reduced as the years passed, as expected.
Answer: 2(12+8) +3
Step-by-step explanation: In the morning they made 12 + 8 airplanes = (12 + 8)
In the afternoon they doubled the number that they made in the morning = 2 (12 + 8)
Finally, you would add 3 to this for the ones that her brother made = 2 (12 + 8) + 3
The answer is 1,1500 because you ha e to subtract the lowest to highest number
This is the concept of transformation, ΔHJK=ΔLMN, from the diagram:
∠H=∠L
∠K=∠N
∠M=∠J
In order to map ΔHJK to ΔLMN, we need to translate K to N and rotate about K until HK lies on the same line containing LN.
