75 is the answer since the 6 is above 5.
Answer: 0.356, 3.65, 35.6, 35.63, 356.06, 356.6
Step-by-step explanation:
When dealing with inverse functions, I like to put them in terms of x and y to make it easier. y=3x-2 and y=-1/3x+2/3
to find the inverse of a function, one method is to switch the variables and then solve for the same variable as the first time, so the inverse of y=3x-2 is x=3y-2, which we now solve for y again.
x=3y-2 => x+2=3y => y=1/3x+2/3 which is not the same as y=-1/3x+2/3
Final answer:
No, f(x) and g(x) are not inverse functions.
Hope I could help :)
Answer:
312
Step-by-step explanation:
First we need to determine the width
A = l*w
6.2 * 10 ^3 = 1.55 * 10 ^2 * w
Divide each side by 1.55 * 10 ^2
6.2 ^ 10 ^3 /1.55 * 10 ^2 = 1.55 * 10 ^2 * w / 1.55 * 10 ^2
Changing from scientific notation to standard
6200/155 = w
40 = w
Then we need to determine the perimeter
P = 2(l+w)
P = 2( 155+40)
P =2( 195)
P = 390
Now multiply by the price
390 *.80

Answer:
steps below
Step-by-step explanation:
f(x) = x⁷ – 6x⁶ + 8x⁵
f'(x) = 7x⁶ - 36x⁵ + 40x⁴
= x⁴ (7x² - 36x + 40) ... (1)
Critical point (x,y): x = 0 , x = (36 ± √(-36)²-4*7*40) / (2*7) = (18±2√11) / 7
x = 0 or x = 3.5 or x = 1.6
plug into (1): y = 0 , y = -394.3 , y = 10.1
extreme : <u>maximum (1.6 , 10.1)</u> <u>minimum (3.5 , -394.3)</u> ... turning points
x⁷ – 6x⁶ + 8x⁵ = x⁵ (x² - 6x + 8) = x⁵ (x-2) (x-4) =0
<u>real zeros: x = 0, x=2, x=4</u>
