The height of the office building is 99.2 meters
The given parameters are:
The above parameters can be represented using the following equivalent ratio
Express as fraction
So, we have:
Multiply both sides by 170
Rewrite as:
Hence, the building is 99.2 meters tall

Answer:
99.17m
Step-by-step explanation:
In the diagram, Marquis is at Point A and the flag pole is length DE, the building is of length BC.
Triangles ADE and ABC are therefore similar right triangles.
Applying this,
[TeX]\frac{|DE|}{|AE|}=\frac{|BC|}{|AC|}[/TeX]
[TeX]\frac{35}{60}=\frac{|BC|}{170}[/TeX]
|BC|=170*35÷60
|BC|=99.17m
On Monday at 1pm, when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
What was the net change in the elevation of the ocean’s surface from 1 p.m. to 7 p.m.?
Answer:
-4.6 ft
Step-by-step explanation:
The question is asking for the net change in the ocean's surface elevation, so we can ignore the parts of the question that mention his own elevation at the time of the measuring. We can see at 1, the elevation was 2.2, and at 7, the elevation was -2.4. The net change is the whole change over the period of time, so we just need to find the difference between the two. Adding them together gives you the distance from each elevation the sea's surface was, which is -4.6 ft as the elevation decreased

Answer:
y = -2
Step-by-step explanation:
-5y - 9 = -(y - 1)
-5y - 9 = -y + 1
-5y + y = 1 + 9
-4y = 10
=
y = -2 Simplify
y = -2
Step-by-step explanation:
since f'(x) = 2f(x) and f(3) has no term of x (so, there must be a constant that eliminates x for x = 3), we get
f(x) = x²/9 × c
c = m×e^n
f(1) = 1/9 × m×e^n = 5
=> m×e^n = 45
f(3) = 9/9 × m×e^n = 45
m = 45
n = 0
