Answer:
Trigonometry can be used to measure the height of a building or mountains
Step-by-step explanation:
if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building. Similarly, if you have the value of one side and the angle of depression from the top of the building you can find and another side in the triangle, all you need to know is one side and angle of the triangle.
To answer this, we need to know the formula of the relationship between the work and the power rating and time.
The formula is:
E(J)<span> = </span>P(W) ×<span> t</span><span>(s)
</span>360000 = 200 * t
t = 360000 / 200
t = 1800 s
So, Emily will spend 1800 seconds in vacuuming. It is also equivalent to 30 minutes.
To find for the composite function of calories burned while
swimming flippers using the two given functions, all we have to do is to plug
in the function of c (t) to the function b (c). By doing this combination, we
can create a function in the form of b [c (t)].
We are given the 2 functions:
c
(t) = 704 t
b
(c) = 1.3 c
To
solve this, just simply combine the 2 but combine c (t) to b(c) since we are
looking for the composite function of calories burned while swimming with
flippers. Not b (c) to c (t).
b
[c (t)] = 1.3 (704 t)
b
[c (t)] = 915.2 t
Answer:
<span>b
[c (t)] = 915.2 t</span>
