Find the distance between points P(5, 1) and Q(1, 3) to the nearest tenth.

bonufazy [111]

Answer:

Idk if its multiple choice but you can do 1 of 2 ways theres using distance formula =√(5-3)sq+(1-4)sq

=√4+9

=√13 <--

or

3.6 units

Given: The two points that are P(5,1) and Q(3,4).

To find: The distance between these two points.

Solution: It is given that there are two points that are P(5,1) and Q(3,4).

The distance between these two points can be found out as using the distance formula that is: 3.6

Thus, the distance between the given two points is 3.6 units.

So you choose 13 or 3.6 Hope this helps :)

Use the law of cosines to find the value of 2*4*5 cos theta

sweet-ann [11.9K]

We can proceed in solving the problem since all information are given such as 2*4*5costheta.
we have a=4, b=5, and C=theta
let us solve for "c" using Pythagorean
c²=a²+b²
c²=4²+5²
c=6.4
Solving for theta or C
c²=a²+b²-2abcosC
6.4²=4²+5²-2*4*5*cosC
C=90

A boat travels 140 miles downstream in the same amount of time as it travels 92 miles upstream. The speed of the current is 6mph

djverab [1.8K]

Answer:

speed of the boat = 29 mph

Step-by-step explanation:

In order to solve the problem, we need to recall the formula for speed (or velocity "v") of an object as the quotient between the distance (d) covered over the time (t) it takes to cover it: $v=\frac{d}{t}$

Now we analyse the two different situations (downstream vs upstream) separately:

Downstream:

Considering that when the boat goes downstream (140 mile trip), it goes with the current, so its velocity (unknown v) couples (adds) to that of the current (6 mph) its total speed would be: v + 6 mph. Therefore we can use this information to write the equation for velocity given above, and solve for time:

$v+6=\frac{140}{t}\\t*(v+6)=140\\t=\frac{140}{v+6}$

Upstream:

In this case, the boat goes against the current, so its speed will be reduced by the current's speed of 6 mph, then its total speed will be: v - 6 mph. Recalling that in this case the boat travels 92 miles in the same time (t) it took it to do the downstream trip, we can write:

$v-6=\frac{92}{t}\\t*(v-6)=92\\t=\frac{92}{v-6}$

Now all we need to do is make these last two equations equal each other since the time used for each trip is the same. We can then solve for the actual speed (unknown v) of the boat:

$\frac{140}{v+6} = \frac{92}{v-6} \\140*(v-6)=92*(v+6)\\140v - 840=92v+552\\140v-92v=552+840\\48v=1392\\v=\frac{1392}{48} =29mph$

In a study of stress levels in U.S. army recruits stationed in Iraq, researchers obtained a complete list of the names of recrui

timama [110]

Answer:

The population in a statistical study is determined by all the individuals that could be part of the study, that is, all the individuals that have common characteristics that make them individuals of interest to the researcher.

In the study of the previous statement, the population is made up of all recruits from the US Army. UU. in Iraq at the time of the study.
