Answer:
-17.5 degrees Celsius in 5 hours
Step-by-step explanation:
0(current temp)-3.5x(temp decrease)=5(hours)
then simplify
-17.5℃
Current temperature = 0 ℃
Rate of falling per hour = -3.5 ℃
Temperature in 5 hours = -3.5 * 5 = -17.5 ℃
(2x + 4)^2 = -35200

, so
Recall that
for all , and knowing that we have
105
Divide 735 by 7
radius ( r) = 1 cm
The volume (V) of a sphere is calculated using the formula
V = πr³
here V is given as V = π
Equating gives
V = πr³ = π
dividing both sides by π, gives
r³ = 1 ( take the cube root of both sides )
r = ∛1 = 1
