What is the Turing point of f(x)=x^2-2x+8

Answers

Answer 1

Answer: method1:parabola
y = x^2 - 2x + 8
y-7 = (x-1)^2 ; parabola
turning point is (1,7)

method2:diff
y = x^2 - 2x + 8
y' = 2x -2 = 0 ==> x = 1,
y=7

Can someone help me with math?Come up with and describe two scenarios: one that models a direct variation situation and one that models an inverse variation situation. Do not state explicitly which scenario is which, but provide at least four data pairs for each situation. Your classmates will have to determine which of the scenarios is a direct variation and which is an inverse variation, and the value of k for each.

Answers

An example of a direct variation scenario is the increase in the income of a start-up bakeshop when the number of cakes sold increase. Example data are (4, $ 100), (5, $ 125), (6, $ 150), and (7, $ 175).

The example of indirect variation scenario is the decrease in time it takes to reach a destination when the speed of the mobile increases. This is shown in the data points: (10 kph, 10 mins), (12 kph, 8 mins), (14 kph, 6 mins), and (16 kph, 4 mins).

Katrina drinks 0.5 gallons of water per day which expression shows how to find the number of cups of water she drinks in a week or 16 cups in a gallon

Answers

Answer:

its B for Ed

Step-by-step explanation:

well we know that 1/2 a gallon (or 0.5 gallons) is equal to 8 cups. So one gallon is 16 cups. (keep this in the back of your mind)

Now to find how many cups she drinks in a day, find out how many gallons she drinks in a week.

So 0.5 (7) = 3.5

Now compute to see how many cups are in 3.5 gallons.

Answers

Answer:

Step-by-step explanation:

If f(x)=x*−81 and g(x)=(x−9)−1(x+9), find g(x)×f(x).

Answers

f(x) = x²-81

g(x) = (x-9) -1(x+9)

= (x-9) -x-9

g(x) • f(x)

= [x²-81 ] • [ (x-9) -x-9 ]

=[ x²-81 ] • [ (x-x -9-9) ]
= [ x²-81 ] •[0-18]
= [ x²-81] •[ -18]

= -18•x² +-81•-18
= -18x²+1458

The cost y (in dollars) to rent a pickup truck is proportional to the number x of hours that the pickup truck is rented. It costs $100 to rent the truck for 4 hours. Write an equation that represents the cost to rent a pickup truck for x hours?

Answers

Answer:

Step-by-step explanation:D∧M a\\

Final answer:

The cost to rent the truck is directly proportional to the number of hours it's rented for. We determine the constant of proportionality to be $25 per hour. Therefore, the equation representing the cost of renting the truck for 'x' hours is y = 25x.

Explanation:

The subject of your question pertains to Mathematics, specifically with relation to a concept called proportionality. In this particular case, the cost of renting a pickup truck (y in dollars) is proportional to the number of hours the truck is rented (x). Since we know that the truck costs $100 for 4 hours, we can use these values to establish a ratio which can be represented as an equation. The ratio of cost to hours is $100/4 hours which simplifies to $25/hour. This is the constant of proportionality. Therefore, the equation that represents the cost to rent the pickup truck for x hours is y = 25x. This equation delineates that for every hour the truck is rented, the cost increases by $25.
