Answer:
Answer in terms of a trigonometric function :
Answer in figures

Step-by-step explanation:
Consider the sketch attached below to better understand the problem.
Let x be the distance between point B and the base of the water tower.


From equation 2,
substituting the value of x into equation 1, we get


cross multiplying,



The height of the tower is
in terms of the trig function "Tan"
The equation can simply be evaluated to get the answer in figures since the angles are given in the question
Answer:
13.18651685
13.9
Explain:
890-238=652
652/890=0.7325842697 (Find out the percentage)
We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.
0.7325842697x18=13.18651685
As you see 18/13.18651685 will equal to 18 (not exactly since it is rounded)
And of course we need to round it to nearest tenth. So the answer would be 13.9!
The absolute value of a number is always positive. It is the distance the number is away from zero.
|-22| = 22
Answer:
The slope is -2
Step-by-step explanation:
8.726 is rounded from the nearest whole number because if you subtract 42,900 from 24.4 and then rounded it it would be 8.726
