Answer:
420,000 J/Kg
Step-by-step explanation:
energy= temperature change* mass* specific heat capacity
energy= 20*5*4200
energy= 420,000
Answer:
so to find the weight of this years model we do this
645*0.8=516
so the answer is 516
Hope This Helps!!!
The correct structure of the question is as follows:
The function f(x) = x^3 describes a cube's volume, f(x) in cubic inches, whose length, width, and height each measures x inches. If x is changing, find the (instantaneous) rate of change of the volume with respect to x at the moment when x = 3 inches.
Answer:
Step-by-step explanation:
Given that:
f(x) = x^3
Then;
V = x^3
The rate whereby V is changing with respect to time is can be determined by taking the differentiation of V
dV/dx = 3x^2
Now, at the moment when x = 3;
dV/dx = 3(3)^2
dV/dx = 3(9)
dV/dx = 27 cubic inch per inch
Suppose it is at the moment when x = 9
Then;
dV/dx = 3(9)^2
dV/dx = 3(81)
dV/dx = 243 cubic inch per inch
29 degrees. You can just add 12 and 17 to find this, since the 12 is negative
40 hundreds flats. 400 tens = 4,000. 40 hundreds also equals 4,000.
