Answer:

500g

Step-by-step explanation:

Because the domula of acceleration is v-u/t so initial velocity is 15 and final velocity is 55 and mass is force * acceleration

The amount of time needed to complete a certain roadtrip, t, varies inversely with the speed of a vehicle, s. At a speed of 52 m

insens350 [35]

Answer:

The time it will take is 13 hours

Step-by-step explanation:

From the given statement, we can generate the following inverse proportion relationship between t and s

t ∝ 1/s

$t = \frac{k}{s} \\\\where;\\\\k \ is \ constant\\\\k = t_1s_1 = t_2s_2 \\\\t_2 = \frac{t_1s_1}{s_2} \\\\t_2 = \frac{12 \times 52}{48} \\\\t_2 = 13 \ hours$

The time it will take is 13 hours

Write an equation of the line, in point-slope form, that passes through the two given points.

EleoNora [17]

(-2,15)(9,-18)
slope = (-18 - 15) / (9 - (-2) = -33/11 = -3

There can be 2 answers to this question....
point slope form : y - y1 = m(x - x1)

(1) using points (-2,15)...
y - 15 = -3(x + 2) <== one possible answer

(2) using points (9,-18)
y + 18 = -3(x - 9) <== another possible answer
