Which of the following could be an example of a function with a domain
2 answers:
Answer:
B. y= - (0.25)^x+ 4
C. y= - (3)^x+4
Step-by-step explanation:
There is no impediment in an exponential function, so all of the have the domain (-infinity, infinity).
In an exponential function in the following format:
The range is (-infinity, b).
So these following functions apply:
B. y= - (0.25)^x+ 4
C. y= - (3)^x+4
A and D have ranges from negative infinity to negative four.

Answer:
≈ 7.6
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (6, 2)
d =
=
=
= ≈ 7.6 ( to the nearest tenth )
Answer:
x = 5.2
Step-by-step explanation:
See the diagram first.
We know that in a triangle if we draw a line parallel to the baseline then it will divide the other two lines of the triangle in the same ratio.
Therefore, from the given figure it is clear that
⇒ 3x = 26 - 2x
⇒ 5x = 26
⇒ x = 5.2 (Answer)
