The parabola that open to right or left has y terms as squared term and the general equation with vertex (h, v) of such a parabola can be written as:

$x=a(y-v)^{2}+h$

The sign of a determines if the parabola opens right or left. For positive a, the direction of parabola is towards right and for negative a it is towards left.

So the correct answer is option B

Alexxx [7]

Since there is no number for the number of pounds for the polar bear, you would use p to represent polar bears. The expression would be: 1578 - p. Good luck

Moritz bought an ottoman that is cube shaped with side lengths of 2 feet. Its lid is removable for storing blankets and pillows.

jeka57 [31]

Answer: Statements that are true are: ()The amount of storage for pillows and blankets is measured in cubic feet and ()The volume of the cube is 8 ft3.

Step-by-step explanation: A cube is a box-shaped solid object that has 6 identical square faces. Volume is the amount of space a enclosed object occupies.

The volume of an ottoman is the amount of storage for pillows and blankets and since it's calculated, in this case, as:

V = length*width*depth, and the unit is in feet, Volume's Unit is in Cubic Feet. That statement is correct.

The lid is a square. The area is: A = 2*2 = 4 square ft, so this statement is incorrect.

The perimeter of the top is: P = 4*2 = 8 feet, but it's not the length of the child safety bumper, so this statement is false.

An ottoman is a cube of side lengths 2 feet, so its volume will be V=8ft3.

Therefore, the correct statements are:

The amount of storage for pillows and blankets is mesured in cubic feet;
The volume of the cube is 8ft3.

Sin97°cos43°+cos97°sin43°

kirza4 [7]

I added a screenshot with the head of the question

Answer:
sin (140°)

Explanation:
Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.

Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°

Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.

Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)

Hope this helps :)

A basketball team has won 50 games of 75

Alex73 [517]

Answer:

27 more games

Step-by-step explanation:

The team has played 75 games so far. Theyve won 50 out of 75 of those games. They still have 45 games left to play. That's 120 games in total. 60% of 120 is 72. They have to win 72 games in total. 72 - 45 = 27. They need to win 27 more games in order to have won 60% of all the games theyve played.
