The formula for t=s/(v₁+v₂), and the value of t is 2 hours.

Step-by-step explanation:

The question is on relative speed.

For the two trains moving towards each other , the relative speed is the sum of their speeds.

Distance between the cities= s miles

Train 1 : speed is v₁ mph

Train 2: speed is v₂ mph

Time of meeting= t

Applying formula for speed, speed =distance/time

Time of meeting= Distance/relative speed

t=s/(v₁+v₂)

Given s=310, v₁=75 and v₂=80, then finding t

t=310/(75+80)

t=310/155 = 2 hrs

Which expression could help you find the distance between (10, 4) and (–6, 4)? A. |10| + |–4| B. |10| + |4| C. |–6| + |4| D. |10
bazaltina [42]
It would be C because |-6| + |4| is basically 6+4 because the lines make the number positive. 6+4 is 10, which is the x value for the point. That 4 unites us the distance between the points.

Question 32 of 40<br> The ratio<br> opposite<br> hypotenuse<br> describes which function?
Helen [10]

The ratio \frac{Opposite}{Hypotenuse } describes the Sine function . The correct option is C. Sine

<h3>Trigonometry </h3>

From the question, we are to determine the function that the ratio of <em>opposite </em>to <em>hypotenuse </em>describes

By SOH CAH TOA

We have that

Sine = \frac{Opposite}{Hypotenuse }

Cosine = \frac{Adjacent}{Hypotenuse }

and

Tangent = \frac{Opposite}{Adjacent}

Hence, the ratio \frac{Opposite}{Hypotenuse } describes the Sine function . The correct option is C. Sine
