Answer:
n = 3.666 or (3 and 2/3)
Step-by-step explanation:
4.5n + 2.5 = 19
4.5n = 19 - 2.5
4.5n = 16.5
n = 16.5 / 4.5
n = 3.666 or (3 and 2/3)
Answer:
To find the inverse of:
Set the function to y:
Rearrange to make x the subject:
Swap x and y:
Change y to the inverse of the function sign:
Rewrite g(x) as a fraction:
Therefore, as the inverse of f(x) ≠ g(x), the functions are NOT inverses of each other
Answer:
Circumference of the circle = 100.53 in.
Step-by-step explanation:
Circumference of a circle is given by the formula,
Circumference = 2πr
Radius of the circle 'r' = 16 in.
Therefore, circumference of the circle with radius 16 in will be,
C = 2π(16)
C = 32π
C = 100.53 in.
Answer:
Difference of squares:
y^4−25
16x^2−81
Not difference of squares:
20m^2n^2−121
p^8−q^5
Step-by-step explanation:
y^4−25
(y²)² - 5²
16x^2−81
(4x)² - 9²
20m^2n^2−121
20 is not a perfect square
p^8−q^5
q⁵ is not a perfect square
