Answer:
x and x+4
Step-by-step explanation:
since area is product of length and breadth for a rectangle . if we factorise the area given , take x as common the other expression comes out to be x+4 . hence dimensions are x and x+4

(1) To solve for h, we manipulate the variable such that it becomes,
h = √(v / 8)
Substituting the given,
h = √ (96 / 8) = √12 ft
(2) To solve for P in this problem, we raise both sides of the equation to exponent 2,
P = I²R
Substituting,
P = (2.5 amps)² x (16 ohms)
P = 100 watts
Final answer:
To find the distance fallen, substitute the given velocity into the equation and solve for h. To find the power being used, substitute the given current and resistance into the equation and solve for P.
Explanation:
1. To find the distance that an object has fallen if its velocity is 96 feet per second, we need to use the given equation v = 8h^(1/2). We'll substitute 96 for v in the equation and solve for h:
96 = 8h^(1/2)
To isolate h, we'll divide both sides of the equation by 8:
12 = h^(1/2)
To get rid of the exponent, we'll square both sides of the equation:
144 = h
Therefore, the object has fallen a distance of 144 feet.
2. The equation IR^(1/2) = √P represents the relationship between current (I), power (P), and resistance (R). We're given that I = 2.5 amps and R = 16 ohms. We'll substitute these values into the equation and solve for P:
(2.5)(16)^(1/2) = √P
(2.5)(4) = √P
10 = √P
To isolate P, we'll square both sides of the equation:
100 = P
Therefore, the appliance is using 100 watts of power.

Answer:
1.75 inches
Step-by-step explanation:
d=2r
Substitute 2.5 in for diameter
3.5=2r
Divide by 2 on both sides
r=1.75 inches
Hope this helps! :)
Answer:
1.75
Step-by-step explanation:
radius is always half of what the diameter is
3.5 divided by 2 = 1.75
