Answer:
67.3°C
Step-by-step explanation:
A = 25, T(0) = 100, T(1) = 90, find T(4)
dT/dt = -k(T - A)
d(T - A)/dt = -k(T - A)
d(T - A)/(T - A) = -k dt
ln(T - A) = lnC - kt
Answer:
8 ft.
Step-by-step explanation:
V = Bh B = area of the base h = height
The base is a circle, so
320π =
r = 4
d = 8 ft.
The ends of the graph go in different directions so this is an polynomial of the odd degree. As the domain values approach negative infinity, the range values approach infinity. As the domain values approach positive infinity, the range values approach negative infinity. This must be an odd degree polynomial with a negative leading coefficient. The answer is B. F(x) = -x^7 + 4x^3 - 2x^2
The formula for the volume of a cube is V = a³ when a = the length of one side.
So, if we say a = 5xy, then...
V = (5xy)³
V = 125x³y³
The volume of the cube is 125x³y³ centimeters³
You are doing an experiment in science and you need to add exactly 250 mL to a beaker. But the markings on the container have rubbed off from so much use. But you have a ruler. By figuring out the volume of the cylinder, you can figure out where the 250 mL line is. :)
