Answer:
<h2>2x² - 16x + 30</h2>
Step-by-step explanation:
p(x) = 2x² - 4x
g(x) = x - 3
To find (pog)(x) replace every x in p(x) by g(x)
That's
(pog)(x) = 2(x - 3)² - 4(x - 3)
= 2( x² - 6x + 9) - 4x + 12
= 2x² - 12x + 18 - 4x + 12
<h3>= 2x² - 16x + 30</h3>
Hope this helps you
Answer:
y = 4x + 4
Step-by-step explanation:
given :
y = 8 
, (1,8)
The equation for the tangent to the curve at the given point
y' = 8. ( 
next calculate the slope of the tangent (m) = y' at x = 1 = 4
hence the equation of the tangent is
y - y' = m( x - x1 )
y - 8 = 4 ( x - 1 )
y = 4x + 4
attached below is the sketch of the curve and the tangent together
Multiply everything by 2 then combine like terms
Answer:
- b = P - a - a - B
- b = P - 2a - B
Step-by-step explanation:
The perimeter is the sum of the lengths of the sides, so is ...
P = B + a + b + a
Subtracting the terms that are not "b" from both sides of the equation, you get
P - a - a - B = b
Swapping sides of the equal sign, this matches the first choice:
b = P - a - a - B
The two "-a" terms are "like terms" so can be added together. The result matches the second choice.
b = P - 2a - B
36 divided by 4 = 9
so then you take 3 times 9 which is 27 so the answer is
g=27
