Answer:
(-67/3, -13/3)
Step-by-step explanation:
In this question, it is given that
The population of a particular village can be modeled by the equation
where x is the number of years since 1990.
And we have to find in what year were there 1706 people living in the village?
So we put 1706 for y and solve for x. That is
Subtracting 56 from both sides.
And 1990 +15=2005
Therefore in 2005, there were 1706 people living in the village
Answer:
1. Yes
2. No
3. Yes
4. Yes
Step-by-step explanation:
#1
Yes, this is a function.
None of the x-values have more than one possible value for y. None of the x-values are repeated in this table.
#2
No, this is not a function.
For each and every value of x, there can only be one y. The x-value 13 has two possible values of y, 4 and -4. This is represented in the coordinates (13, 4) and (13, -4).
#3
Yes, this is a function.
The graph passes the vertical line test. If you were the pass a vertical line through the graph, it would only be touching the graph once, wherever the vertical line is placed.
#4
Yes, this is a function.
The equation given is a quadratic equation for an original parabola. All parabolas, when not inverse, are functions. This parabola opens down, so it will pass the vertical line test.
Answer:
sin θ = 24/25.
Step-by-step explanation:
Cos θ = 7/25 so we have a right triangle with adjacent side = 7 and hypotenuse = 25.
So the opposite side = sqrt ( 25^2 - 7^2) ( By Pythagoras)
= sqrt 576
= 24 .
Therefore sin θ = 24/25.
