Answer:

y = 8/(3√(3x -2))

x = 48 2/3

Step-by-step explanation:

x=34, the root is √(3·34 -2) = √100 = 10. So, we have ...

4/15 = k/10

k = 8/3

The equation is ...

y = 8/(3√(3x -2))

Solving for x, we get ...

3x -2 = (8/(3y))^2

3x = (64/(9y^2)) +2

x = 64/(27y^2) +2/3

For y = 2/9, this is ...

x = 64/(27(4/81)) +2/3 = 64·3/4 +2/3

x = 48 2/3

Jope it helps i did not copy :0 mark me brainliest pls i really need it :)

Cp ps unit 8A: Motion distance and displacement lab activity

bazaltina [42]

The difference from distance and displacement is <u>the direction</u>

<h3>Further explanation</h3>

Distance is a scalar quantity that indicates the length of the trajectory that is traveled by an object within a certain interval. Distance has no direction, only has magnitude

Can be simplified distance = total meters traveled

displacement is a vector quantity that shows changes in the position of objects in a certain interval of time. Displacement has magnitude and direction

Can be simplified displacement = distanced traveled from starting point to ending point

Some examples of distanced and displacement

1. first move: move 4 meters north

second move: move 2 meters south

Distanced: 6 meters

Displacement: 2 meters north

2. first move: move 2 meters east

second move: move 4 meters west

Distanced: 6 meters

Displacement: 2 meters west

etc

For the function y=-3+ cos (x + 4)], what is the minimum value?

Mrac [35]

Answer:

-4 is the mimumum of y=-3+cos(x+4)

Step-by-step explanation:

The minimum value of y=cos(x) is -1.

The minimum value of y=cos(x+4) is still -1; the +4 inside the cosine function only affected the horizontal shift.

The minimum value of y=-3+cos(x+4) is -3-1 which is -4. This brought the graph down 3 units so if the minimum was previously -1 and it got brought down 3 units then it's new minimum is -4.
