Step-by-step explanation:

g(x) = f(2x), so g(x) is f(x) compressed by a factor of 2.

So if the domain of f(x) is [1, 5], then the domain of g(x) is [1/2, 5/2].

A company makes a profit of $50 per software program and $35 per video game. the company can produce at most 200 software progra
Neko [114]
Let x = software program
Let y = video game

x < 200 ; y < 300

x + y < 425

50x ; 35y

x = 200 ; y = 225
50(200) + 35(225) = 10,000 + 7,875 = 17,875

x = 125 ; y = 300
50(125) + 35(300) = 6,250 + 10,500 = 16,750

x = 175 ; y = 250
50(175)  + 35(250) = 8,750 + 8,750 = 17,500

It is more profitable to maximize production of software program when working within the limits provided.

Find the minimum value if f(x) = xe^x over [-2,0]
SashulF [63]

Given function:

f(x)=xe^x

The minimum value of the function can be found by setting the first derivative of the function to zero.

f^{\prime}(x)=xe^x+e^x\begin{gathered} xe^x+e^x\text{ = 0} \\ e^x(x\text{ + 1)  = 0} \end{gathered}

Solving for x:

\begin{gathered} x\text{ + 1 = 0} \\ x\text{ = -1} \end{gathered}\begin{gathered} e^x\text{ = 0} \\ \text{Does not exist} \end{gathered}

Substituting the value of x into the original function:

\begin{gathered} f(x=1)=-1\times e^{^{-1}}_{} \\ =\text{ -}0.368 \end{gathered}

Hence, the minimum value in the given range is (-1, -0.368)

Brian multiplied his average speed of 14.73 miles per hour by the amount of time he spent cross-country skiing. His product was
KonstantinChe [14]

Answer:

Brian's average speed: 14.73 mile/hour

The traveled distance by skiing he estimated: 11.0475 miles.

As the information provided in table, the time he spent for skiing is 0.75

=> The distance Brian traveled by skiing: 14.73 x 0.75 = 11.0475 (miles)

=> Brian's product is correct.

=> Rounding to the nearest whole number => 11.0475 = 11 (miles)

Rounding the Brian's average speed to the nearest whole number:

=> 14.73 = 15 mile/hour

Round the activity time to the nearest whole number:

=> T = 3 + 1.45 + 1.2 + 0.75 = 6.4 = 6 (hour)

Hope this helps!

What is the answer 5i/(2+3i)^2
Nataly_w [17]
Simplify the following:5 i/(3 i + 2)^2
(3 i + 2)^2 = 4 + 6 i + 6 i - 9 = -5 + 12 i:(5 i)/12 i - 5
Multiply numerator and denominator of (5 i)/(12 i - 5) by 5 + 12 i:(5 i (12 i + 5))/((12 i - 5) (12 i + 5))
(12 i - 5) (12 i + 5) = -5×5 - 5×12 i + 12 i×5 + 12 i×12 i = -25 - 60 i + 60 i - 144 = -169:(5 i (12 i + 5))/-169
i (12 i + 5) = -12 + 5 i:(5 5 i - 12)/(-169)
Multiply numerator and denominator of (5 (5 i - 12))/(-169) by -1:Answer: (-5 (5 i - 12))/169

Ram travels 200 km in 2 and a half hours by a car, how long would he take to travel 140
MrRissso [65]

Answer:

x=1.75 hour

Step-by-step explanation:

200km=2.5

140km=x

2.5 * 140=200x

350=200x

x=350/200

x=1.75

the time it will take is x=1.75 hour
