Answer:
dy/dt = - (1/5) ft/s = - 0.2 ft/s
Step-by-step explanation:
Given
L = 5 ft
Qin = 25 ft³/s
Qout = 30 ft³/s
h = 10 ft
dy/dt = ?
We can apply the relation
ΔQ = Qint - Qout = 25 ft³/s - 30 ft³/s
⇒ ΔQ = - 5 ft³/s
Then we use the formula
Q = v*A
where Q = ΔQ, A = L² is the area of square base and v = dy/dt is the rate of change in the depth of the solution in the tank
⇒ ΔQ = (dy/dt)*L²
⇒ dy/dt = ΔQ/L²
⇒ dy/dt = (- 5 ft³/s)/(5 ft)²
⇒ dy/dt = - (1/5) ft/s = - 0.2 ft/s

Answer:
b = 3 or -3 i suppose
Step-by-step explanation:
Hello,
2.3 x 10^9 = ( 1 x 10^3) ( 2.3 x 10^n)
Solution:
Take the logarithm of both sides of the equation to remove the variable from the exponent.

Answer:
5/9
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator. GCD of 10 and 18 is 2.
10 ÷ 218 ÷ 2.
Reduced fraction: 59. Therefore, 10/18 simplified to lowest terms is 5/9.
