A. What iS the slope of the line that passes through (-2, 3) and (4, -5)?

Thepotemich [5.8K]

Answer:

slope = - $\frac{4}{3}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 2, 3 ) and (x₂, y₂ ) = (4, - 5 )

m = $\frac{-5-3}{4-(-2)}$ = $\frac{-8}{4+2}$ = $\frac{-8}{6}$ = - $\frac{4}{3}$

Answer:

The angle between the two sides of the right triangle is aproximately 31.003º.

Step-by-step explanation:

From image attached on question we infer that we need to find the angle between sides of lengths 6 (adjacent leg) and 7 (hypotenuse) in the right triangle. The angle can be found by means of this trigonometric ratio:

$\cos \alpha = \frac{6}{7}$

$\alpha = \cos^{-1} \frac{6}{7}$

$\alpha \approx 31.003^{\circ}$

The angle between the two sides of the right triangle is aproximately 31.003º.

From a point on a river, two boats are driven in opposite directions, one at 7 miles per hour and the other at 11 miles per hour

Bogdan [553]

Answer:

Both boats will be 54 miles apart after 3 hours.

Step-by-step explanation:

Given that from a point on a river, two boats are driven in opposite directions, one at 7 miles per hour and the other at 11 miles per hour, to determine how many hours they will be 54 miles apart, the following calculation must be performed :

54 / (11 + 7) = X

54/18 = X

3 = X

Therefore, both boats will be 54 miles apart after 3 hours.
