Answer:
The domain for given function is
Step-by-step explanation:
Given :
We have to find the domain of the given function.
Domain of a function is defined as a set of value for which the value of function is real and defined.
Consider the given function
Since there is no points for x where the function f(x) is non defined.
Hence, whole number line is the domain for the given function.
In interval form it is written as
Thus, the domain for given function is
The standard form of the equation is
.
See the solution below.
Answer:
Step-by-step explanation:
(a)
For the quadratic equation of the form ,
The discriminant is given as:
Simplifying the given quadratic equation:
[(x-7)^2] - 62 = 19
∴ (x^2) - 14x + 49 = 81
∴ (x^2) - 14x - 32 = 0
Comparing with the standard form of quadratic equation:
a = 1; b = -14; c = -32
∴ Discriminant = (b^2) - 4ac = 196 + 128 = 324
Since Discriminant > 0,
The roots will be real and distinct.
(b)
This equation can be factored as:
(x - 16)(x + 2) = 0;
∴ x = 16 ; x = -2, are the two roots of the equation.
Answer:
468
Step-by-step explanation:
Set it up like the following-
18
26
--------
108
360
--------
408
Take the right number (6) and multiply it with 18
6 x 18 = 108
Now do the same with 2, except put a 0 at the end
2 x 18 = 36
add 0
360
Add both numbers-
360 + 108 = 468
