Find the distance between (3,4) and (4,-6) if necessary, round to the nearest tenth.

Ratling [72]

Answer:

The distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

Step-by-step explanation:

Given the points

(3,4)

(4,-6)

The distance 'd' between (3,4) and (4,-6)

$\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):$

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

substituting the points values

$=\sqrt{\left(4-3\right)^2+\left(-6-4\right)^2}$

$=\sqrt{1+10^2}$

$=\sqrt{1+100}$

$=\sqrt{101}$

$=10.0$ units (Rounded to the nearest the Tenths Place)

Thus, the distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

After robbing a bank in dodge city, a robber gallops off at 14 mi/h. 20 minutes later, the marshall leaves to pursue the robber

Morgarella [4.7K]

For this case we have to write the equation of the position of each one.

We have then:

For the robber:

$r = 14t$

For the marshall :

$r = 16 (t- (\frac{20}{60}))$

$r = 16 (t-\frac{1}{3})$

By the time the marshall reaches the robber we have:

$14t = 16 (t-\frac{1}{3})$

From here, we clear the time.

We have then:

$16t - 14t = \frac{16}{3}$

$2t = \frac{16}{3}$

$t =\frac{8}{3}$

$t = 2.7 h$

Answer:

it takes the marshall to catch up to the robber about 2.7 hours.

Complete the addition. 7/15+1/3+3/5 Please show work.And explain all reasoning.

stellarik [79]

$\frac{7}{15} + \frac{1}{3} + \frac{3}{5} = \frac{7}{15} + \frac{5}{15} + \frac{9}{15} = \frac{21}{15} = \frac{7}{5} = 1.4$

PLEASE HELP!! I WILL GIVE BRAINLIEST

sattari [20]

Answer: (a) The rate that the point 8,28 represents is 3.5 cm/s since 28/8 = 3.5

(b) The unit rate is 3.5 cm/s since the rate is constant.

(c) The two points lie on the same line and that both points results to a rate of 3.5 cm/s.
