Step-by-step explanation:
(2b-3)^2 = (2b-3)(2b-3) = 4b^2-12b+9
Answer:
The tank will contain 202 Ib of salt when it's full.
Step-by-step explanation
To find the amount of salt in the tank at time <em>t= x(t)</em>
If <em>x</em>(0)= 90Ib
To find the volume of the tank at time t
V(t)= 90+(4-3)t=90+t gal

Answer:
C= 5/9 * (F -32)
Move 5/9 to the left which makes it 9/5
9/5 * C = (F -32)
Move the -32 to the left
9/5 * C +32 = F or to make it read left to right
Fahrenheit = 9/5 * Celsius + 32
Step-by-step explanation:
Factor the equation out into (x-5)(x+3)
(x-5)=0
x=5
(x+3)=0
x=-3
x=5, -3
Answer:
<u>h = V/r²</u>
Step-by-step explanation:
The formula is :
- V = r²h (actually 1/3πr²h in real life)
Solving :
- Dividing both sides by r²
- V/r² = r²h/r²
- <u>h = V/r²</u>
