2. algebra
calculus, just take the deritivive and find wher it is 0
y=-0.2x+10
at x=50
sub 50 for x in original
y=250
algebra
for
y=a(x-h)²+k
(h,k) is vertex
k is maximum value
complete the square
y=(-0.1x²+10x)
y=-0.1(x²-100x)
take 1/2 of -100 and square it and add negative and positive inside
-100/2=-50, (-50)²=2500
y=-0.1(x²-100x+2500-2500)
factor perfect square
y=-0.1((x-50)²-2500)
exand
y=-0.1(x-50)²+250
vertex at (50,250)
producing 50 units yeilds a sale price of $250
max price is $250
The gross pay would be $348.75
hope this helps
Answer:
From the given graph , The equation y = x² - 3 x has x-intercept of 3 , 0
Step-by-step explanation:
Given as :
Let The standard equation of line
y = m x + c
where m is the slope of line and c is y-intercept
For, x-intercept , put y = 0
For y-intercept , put x = 0
A) y = x + 3
for x-intercept , y = 0
So, 0 = x + 3
i.e x = - 3
B) y = x² + 3 x
for x-intercept , y = 0
So, 0 = x² + 3 x
i.e 0 = x² + 3 x
Or, x ( x + 3) = 0
Or, x = 0 , x = - 3
C) y = x² - 3 x
for x-intercept , y = 0
So, 0 = x² - 3 x
i.e 0 = x² - 3 x
Or, x ( x - 3) = 0
Or, x = 0 , x = 3
D) x = y² - 3 y
for x-intercept , y = 0
So, x = 0 - 0
i.e x = 0
Hence, From the given graph , The equation y = x² - 3 x has x-intercept of 3 , 0 Answer
