2005= 18,000
2010= 45,000
1) make 2005 year "0", and 2010 year "5"
2)in order to solve this problem and figure out the rate of change, we must use the equation for exponential functions y=ab^x
3) a= the y- value of y intercept ( what does y equal when x is zero) in this case a population number so, a= 18,000; b= the unknown rate of change; x= time and since we're finding b we can plug in 5 for the time in years; y= the value of y in terms of the x-value, so when x is 5, y is 45,000
4) you end up with something like this
45,000= 18,000b^5
5) in order to proceed to solve you must get b alone
6) divide both sides by 18,000
7) so you no have 2.5= b^5
8) take the fifth root of both sides
9) now you have your answer b=<span>1.20112443398</span>
Answer:
Building is 56.58 feet long.
Step-by-step explanation:
Consider the provided information.
An aerial photograph from a U-2 spy plane is taken of a building suspected of housing nuclear warheads.
When the photograph is taken, the angle of elevation of the sun is 30°.
By comparing the shadow cast by the building in question to the shadows of other objects of known size in the photograph, scientists determine that the shadow of the building in question is 98 feet long.
As we know: 
The value of tan 30 degrees is 
Hence, Building is 56.58 feet long.
-2x^2 + 11x - 4
To get this answer, you need to combine like terms. However, before this, remember that you are ADDING, so don’t accidentally subtract any numbers.
Then, just follow these steps:
2x^2 + (-4x^2) = -2x^2
5x + 6x = 11x
-7 + 3 = -4
And proceed to put them in the equation correctly.
Hope this helps!
Sorry I need to answer something so I can ask questions so I’m typing this
