Explanation:
<u>Equation:</u>
This is a decaying exponential function, because the exponent is negative.
Then, the larger the value of t (number of months), the smaller A (the number of hectares).
The factor 1,562.5 is the initial number of hecares, when t = 0.
You must find the value of t when A equals 500, thus solve the equation:
Divide both sides by 1,562.5
Take base-10 logarithms on both sides:
Note that the logarithm of a number decimal number is negative number, thus t will be positive. When you compute that, it is about 4.9 months.

Answer:
-3ad/2 -2bd = c
Step-by-step explanation:
3a + 4b = 1 - 2c/d
⇒3ad + 4bd = d - 2c [multiply d on both sides]
⇒3ad + 4bd - d = -2c [subtract d on both sides]
⇒3ad/(-2) + 4bd/(-2) = c [divide -2 on both sides]
⇒-3ad/2 -2bd = c
Answer:
Q= 8
The amount emptied is 8 gallons of water
Step-by-step explanation:
First we need to create the equation for the above statement.
Q is directly proportional to the square of d
Q= kd²
Q= 50
d= 5
50= k5²
50 = k25
K = 50/25
K = 2
K is the constant of proportionality.
Now our equation is
Q= 2d²
Where Q = volume in gallons
d = pipe diameters in inch
For a pipe of diameter 2 inch
The amount of gallons of water emptied assuming the same kinf of flow is
Q= 2d²
Q= 2(2)²
Q= 2(4)
Q= 8
The amount emptied is 8 gallons of water
