What is the axis of symmetry for y=-x^2+2x+1

Answers

Answer 1

Answer: y = -x² + 2x + 1

$x = (-b)/(2a)$
$x = (-2)/(2(-1))$
$x = (-2)/(-2)$
$x = 1$

y = -x² + 2x + 1
y = -(1)² + 2(1) + 1
y = -1 + 2 + 1
y = 1 + 1
y = 2
(x, y) = (1, 2)

You buy a 24 pack of 591mL bottles of water. How many Liters is that?

Answers

24 bottles x 591 mL/bottle = 14,184 mL

Since 1L = 1000 mL,

14,184 mL x 1L/1000mL = 14,184/1000 = 14.184L (14 whole liters)

Final answer:

The total volume of 24 bottles of 591 milliliters of water is 14.184 liters.

Explanation:

If you have 24 bottles of water each containing 591 milliliters, we first need to convert the volume of one bottle to liters.
Since 1 liter corresponds to 1000 milliliters, one bottle contains 0.591 liters.
Multiplying this value by the number of bottles, which is 24, results in the total volume in liters: 14.184 liters.

Which of the following best describes how the x-axis should be labeled?

From 0 to 6 at intervals of 3

From 0 to 8 at intervals of 4

From 0 to 3 at intervals of 1

From 0 to 5 at intervals of 1

Answers

Based on the given above, the values of the x's are 1, 2, 3, 4. It is best to draw the x-axis and label them from 0 to 5 with an interval of 1 to allow the better plotting of the points. In addition, all the values of the x may be found in the labels of the x-axis.
