Solution Steps

Step 1: Substitute the value of \( x \) into the function

Substitute \( x = -5 \) into the function \( f(x) = x^{2} - 5x \): \[ f(-5) = (-5)^{2} - 5(-5) \]

Step 2: Calculate the squared term

Calculate \( (-5)^{2} \): \[ (-5)^{2} = 25 \]

Step 3: Calculate the product term

Calculate \( -5(-5) \): \[ -5(-5) = 25 \]

Step 4: Combine the results

Add the results from Step 2 and Step 3: \[ f(-5) = 25 + 25 = 50 \]

The value of the function when \( x = -5 \) is \( 50 \).

Final Answer

\(\boxed{50}\)

Let's eat: A fast-food restaurant chain has 604 outlets in the United States. The following table categorizes them by city population size and location, and presents the number of restaurants in each category. A restaurant is to be chosen at random from the 604 to test market a new menu. Round your answers to four decimal places. Population of City Region --- NE SE SW NW Under 50,000 - - - - 50,000-500,000 34 40 13 9 Over 500,000 56 88 70 33 (a) Given that the restaurant is located in a city with a population over 500,000, what is the probability that it is in the Northeast? (b) Given that the restaurant is located in the Southeast, what is the probability that it is in a city with a population under 50,000? (c) Given that the restaurant is located in the Southwest, what is the probability that it is in a city with a population of 500,000 or less?

Directional derivative: Problem 4 (1 point) The figure below shows some level curves of a differentiable function f(x, y). Based only on the information in the figure, estimate the directional derivative: fu(3,3) where u=(-i-j) / sqrt(2) fu(3,3) ≈ 0 (Hint to obtain the best estimate, find the average rate of change over equal increments in the u and -u directions, then find the mean of these two estimates.)
