Answer:
22in²
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Circumference = 25 (1/7)
As we know,
Circumference of a circle = 2πr
By solving this we get
Radius (r) = 4in
Now. we can calculate the area by using following formula,
Area = πr²
By putting the value, we get
Area = (22/7) × 4²
= 22/7 × 16
= 352÷16
Area = 22in²
Answer:3

Answer:
7
Step-by-step explanation:
Answer:
Its 1 million
Step-by-step explanation:
Answer: To find the inverse of the function, we need to make x as a function of y and at the final step make a switch between x and y (i.e. make x as y and y as x)
y = x² + 4x + 4 ⇒⇒⇒ factor the quadratic equation
y = (x+2)(x+2)
y = (x+2)² ⇒⇒⇒ take the square root to both sides
√y = x+2
x = √y - 2 ⇒⇒⇒ x becomes a function of y
final step:
∴ y = √x - 2 ⇒⇒⇒ the inverse of the given function
So, as a conclusion:
f(x) = y = x² + 4x + 4 ⇒⇒⇒ the given function
f⁻¹(x) = y = √x - 2 ⇒⇒⇒ the inverse of the given function
