To find the last angle, add the 90 degree angle and 65 degree angle.(155)
Since a triangle has a total of 180 degrees, subtract 155 from 180 to get the third angle.(25 degrees)
To find the last side, use the pythagorean theorem(a^2 + b^2 = c^2)
a^2 + 77^2 = 85^2
solve, and you'll get the last side
.625
62.5%
to find decimal divide top # by bottom # and them move decimal 2 places to the right
Answer:
The object will hit the ground after 9 seconds.
Step-by-step explanation:
We are given the function:
Where <em>h</em> is the height of the object after time <em>t</em>, <em>v</em>₀ is the initial velocity, and <em>h₀</em> is the initial height.
An object is thrown upwards from a height of 720 feet and an initial velocity of 64ft/s. We can to determine how long it will take for the object to reach the ground.
Hence, <em>h₀ </em>= 720 and <em>v₀</em> = 64. Substitute:
When the object reaches the ground, its height <em>h</em> above the ground will be zero. In other words:
Solve for <em>t: </em>
<em /><em />
<em />
Since time cannot be negative, we can ignore the first solution.
In conclusion, the object will hit the ground after 9 seconds.
Since the population increases by 7 percent each year, we can multiply 850 by 1.07 seven times. In other words, we can do 850 • 1.07^7. This is equal to about 1365.
