Answer: 1 1/12 (aka 13/12)

Step-by-step explanation: First, I did 3 x 1/4 (3/4) and with 3/4, I used the denominator (4) and multiplied both the numerator and denominator (with this I used 1/3) and multiplied 3 x 4 and 1 x 4 and got 4/12. Now I take the denominator of 3 (from 1/3) and multiply the numerator and denominator from the 3/4, and 3 x 3 and 3 x 4 which got me 9/12. Lastly, I did 9/12 and 4/12 and got 13/12 which is just 1 1/12

ANEK [815]

Answer:

22123

Step-by-step explanation:

→ Find the multiplier

3% decrease = 0.97

→ Multiply the population by the multiplier which is to the power of years

30000 × 0.97¹⁰ = 22122.7 = 22123

First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20

Final answers:
First car=20 gallons
Second car=35 gallons

Find the absolute extrema of f(x) = e^{x^2+2x}f ( x ) = e x 2 + 2 x on the interval [-2,2][ − 2 , 2 ] first and then use the com

fredd [130]

$f(x)=e^{x^2+2x}\implies f'(x)=2(x+1)e^{x^2+2x}$

$f$ has critical points where the derivative is 0:

$2(x+1)e^{x^2+2x}=0\implies x+1=0\implies x=-1$

The second derivative is

$f''(x)=2e^{x^2+2x}+4(x+1)^2e^{x^2+2x}=2(2x^2+4x+3)e^{x^2+2x}$

and $f''(-1)=\frac2e>0$ , which indicates a local minimum at $x=-1$ with a value of $f(-1)=\frac1e$ .

At the endpoints of [-2, 2], we have $f(-2)=1$ and $f(2)=e^8$ , so that $f$ has an absolute minimum of $\frac1e$ and an absolute maximum of $e^8$ on [-2, 2].
