Step-by-step explanation:
Given the exponential function as
substitute both points in the equation above
point (-3,16) will be
point (-1,4) will be
make a the subject of the formula in both equations above
This means
Cross multiply as;
Divide by 4 both sides to get
Divide by b^-1 both sides
Find value of a
Hence
a=2 and b=1/2 thus write the equation as;
Given :
Ruben put an empty cup underneath a leaking faucet.
After 1 ½ hours, Ruben had collected ¼ cup of water.
To Find :
The rate, in cups per hour, at which the water is leaking from the faucet.
Solution :
Rate in which cup is filling with water.
Therefore, the rate is 0.167 cup/hour.
Answer:
Area of the trapezoid = 36√6 cm²
Step-by-step explanation:
Area of the trapezoid = height ( base1+ base2/2)
height = √36
base1= 3√6
base 2= 3√54
Putting the values in the formula
Area of the trapezoid = height ( base1+ base2/2)
= √36 ( 3√6+3√54/2)
= 6 ( 3√6+3√6*9/2) Factoring
= 6 ( 3√6+3*3√6/2) Multiplying
= 6 ( 3√6+9√6/2) adding
= 6 ( 12√6/2)
= 6 ( 6√6)
= 36√6 cm²
