Answer:
No. The reciprocal of a function is rarely the same as the inverse of the function.
Step-by-step explanation:
tan^1(a) signifies the arctangent function, the function that returns the angle for a given tangent value of a.
tan(a)^-1 signifies the reciprocal of the tangent function, which is the definition of the cotangent function.
The attached graph compares the two functions.
Answer:
A quadratic function whose zeros are 2 and 7 is f(x) = x^2 - 9x + 14
If the zeros of a quadratic function are a and b, the quadratic function will be given as:
f(x) = (x - a)(x - b)
For the function f(x) whose zeros are 2 and 7:
f(x) = (x - 2)(x - 7)
Expand the equation
f(x)= x^2 - 7x - 2x + 14
f(x) = x^2 - 9x + 14
Therefore, a quadratic function whose zeros are 2 and 7 is
f(x) = x^2 - 9x + 14
Area = pi x radius squared... so
a = pi x 10in^2
a = 314.159
5y + 7 = 52
5y = 52 - 7
5y = 45
y = 9

=
3(x+12) = 2 x 42
3x + 36 = 84
3x = 84 - 36
3x = 48
x = 16
Angle H = 180 - 52 - 36 = 92
Answer:
£3,543.54
Step-by-step explanation:
Amount after 2 years = Principal + interest
Get the interest
Interest = PRT/100
Interest = 3003 * 9 * 2/100
Interest = 3003 * 18/100
Interest = 30.03 * 18
Interest = 540.54
Amount after 2 years = 3003 + 540.54
Amount after 2 years = £3,543.54
