Answer:
The weight of the block of ice after 1 day is of 4.81 pounds.
Step-by-step explanation:
Equation for exponential decay:
The equation that models an amount after t hours, subject to exponential decay, is given by:
In which A(0) is the initial amount and r is the decay rate, as a decimal.
A 10-pound block of ice melts at a rate of 3% per hour.
This means that 
So
Find the weight of the block of ice after 1 day.
One day has 24 hours, so this is A(24).
The weight of the block of ice after 1 day is of 4.81 pounds.
Radius = 1/2 * diameter = 5
Equation is (x - (-4))^2 + (y - 9)^2 = 5^2
(x + 4)^2 + (y - 9)^2 = 25 is the answer
F(-5) = 2(-5) + 1 = -9
g(-5) = (-5)^2 = 25
(f*g)(-5) = -9(25) = -225
Answer:
375 gallons in 25 minutes
Step-by-step explanation:
first decide how many gallons in one minute
300/20 = 15 gallons in one minute
next multiply 15 x 25 minutes. You get 375 gallons in 25 minutes
Answer:
D) The third side could be 4 meters long.
Step-by-step explanation:
The third side of a triangle must be greater than the difference and less than the sum of the other two sides.
5-4=1
5+4=9
So the third side must be GREATER THAN 1 and LESS THAN 9. (1<x<9)
Therefore, the answer can't be A or C. The second one <em>could </em>be correct, depending on how much less than 4 it is. But the last one is definitely correct.
