The sum of the interior angle of the triangle is 180 degrees. Then by the sine rule, angle E can be determined. Then the correct option is A.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
For triangle DEF, the length of side e and the measures of angles D and F are known.
We know that the sum of the interior angle of the triangle is 180 degrees. Then the angle E can be determined.
Hence the sine rule is easy to apply.

Evaluate f(-2): SHOW ALL WORK
f(x) = 3/2x -4?
Answer:
-7
Step-by-step explanation:
f(-2) = 3/2(-2) - 4
f(-2) = -3 - 4
f(-2) = -7
Answer:
f(-2) = -7
Step-by-step explanation:
f(-2) means that for every x given in the equation, -2 would be substituted in it's place. Therefore;
[tex]f(-2)=\frac{3}{2} (-2) - 4[/tex]
f(-2) = -3 - 4

Answer:
True, false, true
Step-by-step explanation:
Because the minimum value of f(x) is -1, and the minimum value of g(x) us -25. It comes only once.
Roots are the points on the x - axis or when the x is 0. The roots of f(x) are positive.
f(0) means when x is 0, so f(0) = 3 or 5, and g(0) = -24

assume f is a one to one function of f(x)= 4-6x find f^-1(-32)
Answer:
f^-1(-32)=6
Step-by-step explanation:
Find the inverse of the function f(x)=4-6x:
f(x)=4-6x
y=4-6x
x=4-6y
x-4=-6y
(x-4)/-6=y
-1/6x+2/3=y
y=-1/6x+2/3
f^-1(x)=-1/6x+2/3
Plug in f^-1(-32) for f^-1(x) and simplify:
f^-1(-32)=-1/6(-32)+2/3
f^-1(-32)=16/3+2/3
f^-1(-32)=18/3
f^-1(-32)=6

O x | x is a real number}
Answer:
c
Step-by-step explanation:
hi
The domain of f(x) = 5x - 7 is {x | x is a real number} and this can be denoted as (-∞, ∞) for all x ∈ R.
What is domain?The domain is the set of all the input values given to a function.
Given is an expression f(x) = 5x - 7, we need to find the domain,
We know that,
The domain of any expression is set to all the real numbers, except where the expression is undefined.
Therefore, the domain is all real numbers.
Also,
The graph of the function will be a straight line without discontinuities.
Hence the domain of f(x) = 5x - 7 is {x | x is a real number} and this can be denoted as (-∞, ∞) for all x ∈ R.
