36 cm²s⁻¹ is the rate at which the area of the square is increasing.
Given each side of the square is increasing at a rate of 6cm/s
Area, A = s², s is the side length
=>
{chain rule of differentiation}
= 6 cm/s
When A = 9 cm² => 9 = s²
=> s = √(9) => s = 3 cm
Hence,
= 2 × 3 × 6 = 36 cm²s⁻¹
Hence, 36 cm²s⁻¹ is the rate at which the area of the square increases

Step-by-step explanation:
180-90-48=42
Answer:
y = 4 cosx
Step-by-step explanation:
The standard form of cosine is
y = acos(bx)
where amplitude = | a |
with maximum value a and minimum value - a
The only expression in this form is
y = 4cosx
'is' in mathematics means equal
'of' in mathematics means multiplication
Translating 8 is 50% of what number into an equation, we get:
8 = 50% * x
50%, or 50 percent, is nothing but 50 over 100 or 50/100, which is the same as 1/2.
8 = 1/2 * x
Multiply 2 on both sides.
8 * 2 = 1/2 * 2 * x
16 = x
x = 16
8 is 50% of 16.
