Answer:
we cant see the picture
Step-by-step explanation:
<span>In one million there are 420 positive numbers with the sum of their digits equal to 13 and with one digit equal to 9</span>
Find the stationary points.
<em>f(x)</em> = 3<em>x</em> ⁴ - 4<em>x</em> ³ - 12<em>x</em> ² + 1
<em>f '(x)</em> = 12<em>x</em> ³ - 12 <em>x</em> ² - 24<em>x</em>
Solve <em>f</em> <em>'(x)</em> = 0.
12<em>x</em> ³ - 12 <em>x</em> ² - 24<em>x</em> = 12<em>x</em> (<em>x</em> ² + <em>x</em> - 2) = 12<em>x</em> (<em>x</em> - 1) (<em>x</em> + 2) = 0
→ <em>x</em> = 0, <em>x</em> = 1, <em>x</em> = -2
Check the value of <em>f</em> at the stationary points.
<em>f</em> (0) = 1
<em>f</em> (1) = -12
<em>f</em> (-2) = 33
Check the value of <em>f</em> at the boundary of the domain.
<em>f</em> (3) = 28
(We've already checked <em>f </em>(-2).)
Then over [-2, 3], we have max(<em>f</em> ) = 33 and min(<em>f</em> ) = -12.
Answer:
The customer would pay $24,073 for Car R
Step-by-step explanation:
5% of 25,340 is 1267
so you subtract 1267 from 25,340 and get 24,073
