Answer:
$11,714
Step-by-step explanation:
C(x) = 0.7x² - 462x + 87,944
this is a quadratic equation that opens up
the vertex will be the minimum
From the quadratic formula the x coordinate of the vertex is
x = -b/2a
x = 462/(2 * 0.7)
x = 330
Plug in
c(330) = 0.7(330²) - 462(330) + 87,944
c(330) = 11,714
$11,714
youll get 2and 3/4 then divide by 2 and you get 1.0375=2 and 3/80
hope this helps!
the line-of-sight distance from the television camera to the base of the stadium is 1449.28 m .
<u>Step-by-step explanation:</u>
A blimp provides aerial television views of a baseball game. The television camera sights the stadium at a 12° angle of depression. The altitude of the blimp is 300 m. We need to find What is the line-of-sight distance from the television camera to the base of the stadium . Let's find out:
According to question , given scenario is in a right angle triangle where
, where x is angle of depression.
We know that 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , the line-of-sight distance from the television camera to the base of the stadium is 1449.28 m .
