Answer: 3.
Step-by-step explanation:
Answer:
B) As the age increases, the height increases.
Step-by-step explanation:
There is a clear trend that is shown with a positive slope. That means that the the <em>variables, here, the age and the height, are directly proportionate to each other</em>. That means our answer is <em>B or D</em>.
Another note is that in a situation like this, the y-variable is dependent on the x-variable. So, here, that means that <em>the height depends on the age</em>. So, the answer is B, since in a sentence structure like so indicates that the second variable is dependent on the first.
Answer:
a = -
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (105, 27 ) , thus
y = a(x - 105)² + 27
To find a substitute (109, 14 ) into the equation
14 = a(109 - 105)² + 27 ( subtract 27 from both sides )
- 13 = 16a ( divide both sides by 16 )
a = -
X is equal to 81 cuz you would subtract 14 from both sides then find out what multuplied by 4 is the square root of 18
