By cross,
$by \: cross \: \frac{10 - 3x}{5} = \frac{22}{5x} = 50x15x ^{2} = 110x = 50x - 110x + 15x ^{2} = - 60x + 15x ^{2} = by \: 15x \: - 4 + x = x = 4$

faltersainse [42]

Answer:

0.395 kilometers

Step-by-step explanation:

Please consider the complete question.

On Martin's first stroke, his golf ball traveled 4/5 of the distance to the hole. On his second stroke, the ball went into the hole. Martin was standing 79 meters from the hole as he took his second stroke. How many kilometers from the hole was Martin when he started?

Let x represent the distance between hole and start point.

In 1st stroke ball traveled 4/5 of the distance, so 1/5 of the distance was remaining from 2nd stroke to hole. This means the 1/5 of whole distance between start point and hole is equal to 79 meters.

We can represent this information in an equation as:

$\frac{1}{5}x=79$

$\frac{1}{5}x\cdot 5=79\cdot 5$

$x=395$

Since our distance is in meters, so we will convert 395 meters into kilometers by dividing by 1000.

$395\text{ meters}=\frac{395}{1000}\text{ km}=0.395\text{ km}$

Therefore, Martin was 0.395 kilometers from the hole, when he started.

The cartesian coordinates of a point are given. find polar coordinares of the point where r<0 and

Ad libitum [116K]

Find the polar coordinates in the usual way, then negate r and add 180° to θ.

You know that

... r = √(x² + y²)

... θ = arctan(y/x) . . . . . taking quadrant into account

The coordinates (r, θ) and (-r, θ+180°) specify the same point.
