Answer:
A) 0 ≤ x ≥ 5
B) Number line is attached
C) Interval notation is; (0,5)
Step-by-step explanation:
We are told that the number is greater than zero and less than or equal to 5. If the number is x, then we can write the inequality as;
i) 0 ≤ x ≥ 5
ii) The solution graphed on a number line is attached.
iii) Since 0 ≤ x or x ≥ 5, then the interval notation is; (0,5)
For this, just subtract both sides by 12x and <u>your answer will be </u>
Decreasing in quantity according to the law is the definition of exponential decay. but what are the choices you can chose from?
Answer:
multiply all the numbers
Step-by-step explanation:
Answer:
The depth of the reflector is 0.84 feet
Step-by-step explanation:
<em>(See the figure below)</em>
The equation of a parabola centered at the origin with an axis of symmetry on y-axis is:
(1)
With p the distance from the origin to the focus using p=6, the equation (1) of the parabola becomes:
(2)
Note that the point B is on the parabola, so this point should satisfy the parabola equation (2) that allow us to use the value x=4.5 to find the y value associated to it, that it is the depth (h) of the reflector:
, solving for y
