Lets solve it
first multiply each term by x :-
x^2 - 7 = 6x
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
x = 7 and x = -1
It would have a greater slope and perhaps start higher on the y axis.
Answer:
120 m
Step-by-step explanation:
Let the length of the pole be a and the shadow be b at 58° and b+90 at 36°.
<u>Then, as the pole and its shadow form a right triangle, we have:</u>
<u>As,</u>
- tan (58°) ≈ 1.6
- tan (36°) ≈ 0.727
<u>The equations change to:</u>
<u>Comparing the two equations:</u>
- 1.6b = 0.727b + 0.727*90
- 1.6b - 0.727b = 65.43
- 0.873b = 65.43
- b = 65.43/0.873
- b ≈ 75
<u>Then </u>
- a = 1.6b = 1.6*75 = 120 m
17.4 ml is equivalent to 1.74e-5 kl.
