Liana started to evaluate the function f(x) = 2x2 – 3x + 7 for the input value 2.f(x) = 2(2)2 – 3(2) + 7

= 2(4) – 3(2) + 7

What is the value of the function when x = 2?

Answers

Answer 1
Answer: f(x) = 2x² - 3x + 7

x = 2

f(2) = 2(2²) - 3(2) + 7
f(2) = 2(4) - 6 + 7
f(2) = 8 - 6 + 7
f(2) = 15 - 6
f(2) = 9

The value of the function when x = 2 is 9.
Answer 2
Answer: If you would like to know the value of the function when x = 2, you can calculate this using the following steps:

f(x) = 2 * x^2 - 3 * x + 7
x = 2
f(2) = 2 * 2^2 - 3 * 2 + 7 = 2 * 4 - 6 +7 = 8 - 6 + 7 = 9

The correct result would be 9.

Can you go to grandmas estate and measures 8 inches across by 2 inches high if the actual stadium measures 500 feet across which equation can be used to find ex the height of the stadium in feet

Answers

Answer:

Step-by-step explanation:

Given that,

The estate is estimated as 8in across and the actual measure across is 500 ft

Then, this shows that

8in represent 500ft on scale

Then, divide both sides by 8

1in will represent 62.5ft

Now, we are told that the height of the stadium is estimated as 2inches, so what is the real value in ft

Since, 1in =62.5ft

Then, multiply both sides by 2

Therefore, 2in=125ft.

The height of the stadium in feet is 125ft

The price of an item has dropped to $102 today. Yesterday it was $120. Find the percentage decrease.

Answers

Using cross multiplication, 102/120=x/100 ---> 120x=10200 divide the entire problem by 120 ---> 85. 102 is 85% of 120, so the item has dropped in price by 15%

Final answer:

The decrease in price is $18. The percentage decrease is calculated by dividing the decrease by the original price and multiplying by 100, which results in a 15% decrease.

Explanation:

The problem involves finding the percentage decrease of a price from $120 to $102. The first step is to find out how much the price decreased. This involves subtracting the new price ($102) from the original price ($120), which gives us an amount of $18. Now, the percentage decrease is computed by dividing this decrease ($18) by the original price ($120) and multiplying the result by 100. Hence, Percentage decrease = ($18 / $120) * 100% = 15%.

Therefore, the price has decreased by 15% from yesterday to today.

A snowbank that is 6 inches deep is melting at a rate of 0.5 inch per hour. Write a linear function to model the scenario and identify the domain and range of the function.

Answers

Answer:

y = -0.5x + 6, Domain [0,12] and Range [0, 6]

Step-by-step explanation:

The slope in a linear function represents the rate of change. Since the amount of snow is decreasing (indicating a negative slope) at 0.5 inches an hour, our slope would be -0.5.

Our y intercept, 6, would be the starting amount of snow. At 0 hours, no snow has been melted.

Our domain is [0,12] these are the x values from where at zero there is 6 inches of snow and at 12 there is 0 inches of snow.

Finally, our range is [0,6]. Since there cannot be no more than 6 or less than 0 inches of snow, our range is [0,6]

Hope this helped!
