Answer:
Step-by-step explanation:
Since log is defined by all positive real numbers
therefore domain is all positive real number that is ( 0,∞)
Range is given by real numbers
inverse of the given function is (10^x)/7
Whose domain is all real numbers and range is all positive real number
And since we know that domain of function and range of its inverse
& range of a function and domain of its inverse is same
which we are getting in the problem
so answer is justified
Answer:
47 degrees
Step-by-step explanation:
The two angles shown are "vertical angles" and thus are equal.
Thus, 2x + 3 = x + 50
Combining like terms, we get:
x = 47 degrees
Answer:
150 in

Answer:
The answer is (30, 109)
Step-by-step explanation:
In this problem we need to find the intersection point between the lines
y = 4x-11
and
y = 3.2x+13
We can easily solve this problem by plotting both lines in a graphing calculator and finding the intersection point.
Please see attached picture.
The answer is (30, 109)
