Answer:

The equation in point-slope form of the line is:

y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)

Step-by-step explanation:

Given the points

  • (-1, -5)
  • (3, 2)

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(3,\:2\right)

m=\frac{2-\left(-5\right)}{3-\left(-1\right)}

m=\frac{7}{4}

As the point-slope form is defined as

y-y_1=m\left(x-x_1\right)

where m is the slope.

substituting the values m=7/4 and the first point (-1, -5)

y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)

Therefore, the equation in point-slope form of the line is:

y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)

A system for tracking ships indicated that a ship lies on a hyperbolic path described by 5x2 - y2 = 20. the process is repeated
malfutka [58]
Answer:
The ship is located at (3,5)

Explanation:
In the first test, the equation of the position was:
5x² - y² = 20 ...........> equation I
In the second test, the equation of the position was:
y² - 2x² = 7 ..............> equation II
This equation can be rewritten as:
y² = 2x² + 7 ............> equation III

Since the ship did not move in the duration between the two tests, therefore, the position of the ship is the same in the two tests which means that:
equation I = equation II

To get the position of the ship, we will simply need to solve equation I and equation II simultaneously and get their solution.

Substitute with equation III in equation I to solve for x as follows:
5x²-y² = 20
5x² - (2x²+7) = 20
5x² - 2y² - 7 = 20
3x² = 27
x² = 9
x = <span>± </span>√9

We are given that the ship lies in the first quadrant. This means that both its x and y coordinates are positive. This means that:
x = √9 = 3

Substitute with x in equation III to get y as follows:
y² = 2x² + 7
y² = 2(3)² + 7
y = 18 + 7
y = 25
y = +√25
y = 5

Based on the above, the position of the ship is (3,5).

Hope this helps :)
