Answer:
option-B
Step-by-step explanation:
we know that
Sum rule of logarithm:
which is same as
the log of a product (ab) is equal to the addition of log a nad log b
Subtraction rule of logarithm:
which is same as
the log of the quotient of a and b is equal to the log of a minus the log of b
Exponent rule of logarithm:
which is same as
the log of the quantity a raised to b is equal to the product of b and the log of a
so,
option-B is not correct
Answer:
Step-by-step explanation:
(x₁, y₁) is the 1st coordinate while (x₂, y₂) is the 2nd coordinate.
Gradient of the line
19
Step-by-step explanation:
when we add 9 and 10 we will get sum 19
Solution :
Let A = Economics, B = Mathematics
n(A) = 311, n(B) = 243, 
a). So, 
= 311 + 243 - 135
= 419
b). n(A only) = 311 - 135
= 176
n(B only) = 243 - 135
= 108
Exactly one of these two courses
= 0.568
c). Neither economics nor mathematics
= 0.162
The equation that must be true regarding the function is a. f(–3) = –5
<h3>
How to explain the information?</h3>
The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?
a. f(–3) = –5
b. f(–3, –5) = –8
c. f(–5) = –3
d. f(–5, –3) = –2
The question is what does the point (-3, -5) correspond to on the graph of the function.
If we have a point on a graph in the Cartesian coordinate system then that point consists of coordinates (x, y). In other words, y=f(x) and x so (x, f(x)) where x is a x-coordinate and y=f(x) is y-coordinate.
Hence if we have a point (-3, -5) the corresponding coordinates are x=-3 and y=f(x)=-5.
Therefore the correct answer is f(-3)=-5.
