Answer:
-3 ≥ x ≥ 9
Step-by-step explanation:
The domain are the x-values of every point in your graph. Since it a continuous domain, it'll be represented with ≥. Your two extremities are -3 and 9. Therefore, your domain is -3 ≥ x ≥ 9.
The average rate of change over the interval is 2.17
Explanation:
Given that the cost of a floral bouquet after a discount is given by the function
We need to determine the average rate of change over the interval
The average rate of change can be determined using the formula,
where and
Substituting the value of a and b in the function, we get,
Hence, substituting these values in the formula, we get,
Simplifying, we get,
Dividing, we have,
Thus, the average rate of change over the interval is 2.17
Answer:
26
Step-by-step explanation:
here,
the lower angle when sumed,
it is like: 154+a=180 (let angle be a) being supplementary angle sum is 180
so value of a becomes 26
then,
the above angle x is corresponding to angle a (a=x)
So value x is 26
Answer:
D=221 m
Step-by-step explanation:
In order to solve this problem, we can start by drawing a diagram of the given situation. (see attached picture)
As you may see, we have a right triangle there, so we can use trigonometric functions to solve this. Specifically, the sine function.
in this case we need to find the hypotenuse, so we solve the equation above for the Hyp, so we get:
in this case, the opposite side (OS) is the heght of the helicopter, the angle is the 42° and the Hyp is the direct distance between the helicopter and Jackson, so we substitute the given data to get:
Which yields:
D=221m
