Answers

Answer 1

Expressions in component form for the position vectors having the  polar coordinates are:

a) -12 cos(40)i + 12sin(40) j = -9.19i + 7.71j

b) 3cos(40) i + 3 sin(40) j = 2.29i + 1.92j

c) -24cos(48)i - 24sin(48) j = -16.059i - 17.83j

Polar coordinates can be found in :

Use one or more of the following equations: cos=xr, sin=yr, tan=yx, and r=x2+y2 to convert rectangular coordinates to polar coordinates.

What exactly are polar coordinates?

The polar coordinate system is indeed a two-dimensional coordinate system in which the distance from a reference point and the angle from a reference direction are used to determine each point's location on a plane. The polar axis is the ray emanating from the pole inside the reference direction. The pole is the point of reference.

According to the Given information:

Let the +x and +y represent, respectively, the unit vectors represented by I and j.

(a) 12.6 m, 130° counterclockwise from the +x axis [tex]\overrightarrow{\mathrm{R}}[/tex]= m.

    -12 cos(40)i + 12sin(40) j

Find the measures of the interior angles of the triangle

please help

Answers

Answer: x = 88 degrees

Step-by-step explanation:

The angles of a triangle add up to 180 degrees.

So

48 + x + (x - 44) = 180

48 + 2x - 44 = 180

2x + 4 = 180

2x = 176

x = 88

Angle B = 88 degrees

A student states that a triangle can be formed with side lengths 3 in, 5 in, and 9 in. is the student correct? why, or why not? yes, because 3 5 < 9 yes, because 3 9 > 5 no, because 3 9 > 5 no, because 3 5 < 9

Answers

A student is not correct when he stated that a triangle can be formed with side lengths 3 in, 5 in, and 9 in because 3 + 5 < 9.

A triangle is a polygon with three sides and three vertices.

To know if a set of numbers is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 3, b = 5, and c = 9

a + b > c : 3 + 5 > 9     8 > 9     False

a + c > b : 3 + 9 > 5     12 > 5     True

b + c > a : 5 + 9 > 3     14 > 3     True

If at least one of these statements does not hold true, the measurements can't be the sides of a triangle.

what bigger 3/5 or 0.85

Answers

Answer:

0.85 is bigger

Step-by-step explanation:

To compare fractions you need to bring them to the same format.

1) Convert 3/5 to decimal:

3/5 = 30/50 = 60/100 = 0.60

Compare:

0.60 < 0.85 as 60 < 85

2) Convert 0.85 to fraction:

0.85 = 85/100 = 17/20

Bring 3/5 to the same denominator:

3/5 = (3*4)/(5*4) = 12/20

Compare:

12/20 < 17/20 as 12 < 17 (comparing the numerators)

Ari has a total of 22 coins consisting of pennies and nickels. The total value of the coins is $0.54 Which equation can be used to find the number of pennies Ari has?

Answers

n = the number of nickels
p = the number of pennies

Total number of coins she has = 22.

n + p = 22

First equation

Each penny is one cent and a nickel is worth 5 cents

And the total is $0.54

Second equation. 0.05n + 0.01p = 0.54

n + p = 22
0.05n + 0.01p = 0.54

Multiply the top equation by -0.05 which gives us

-0.05n - 0.05p = -1.1
0.05n + 0.01p = 0.54

The n terms cancel out which leaves the p value

-0.04p = -0.56

Divide by the -0.04p and you get p=14


Substitute the value of p back into the top equation.

Which is n + 14 = 22

Subtract 14 and you get n = 8

Ari has 8 nickels and 14 pennies

How long will it take you to ski a distance of 36 miles at the speed of 5 miles per 45 minutes

Answers

To ski a distance of 36 miles at the speed of 5 miles per 45 minutes, will take 324 min

The formula and procedure we will use to solve this exercise is:

t = x/v

Where:

x = distancet = timev = velocity

Information about the problem:

v = 5 miles per 45 minutesx = 36 milest = ?

Calculating the velocity we have:

v = x/t

v= 5 miles/45 min

v = 0.111 miles/ min

Applying the time formula from the uniformly rectilinear motion (URM), we have:

t = x/v

t = 36 miles/0.111 miles/ min

t = 324 min

What is velocity?

It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).

Create a data set of 9 numbers that has a mean of 10 and a maximum of 15​

Answers

Answer:  {5, 6, 7, 8, 10, 12, 13, 14, 15}

Other answers are possible.

=========================================================

Explanation:

Let's say 10 is the median, and we'll have four values above it and four below. This gives 4+1+4 = 9 total items. One such example could be {6,7,8,9,10,11,12,13,14}. This is the set of whole numbers from 6 to 14 inclusive.

Due to the symmetry of that list, the mean = median = 10

The only problem is the max is 14, when we want it to be 15. We can fix this by adding 1 to each of the upper four values {11,12,13,14} to get {12,13,14,15}.

To balance things out, subtract 1 from each of the lower four values. So we go from {6,7,8,9} to {5,6,7,8}. This balancing is to keep the mean the same at 10.

Therefore, the set  {6,7,8,9,10,11,12,13,14} becomes {5,6,7,8,10,12,13,14,15} which is one possible answer.

There are infinitely many other possible answers. The data set does not have to be symmetric like this.

Write the equation of the line in fully simplified slope-intercept form.

Answers

The equation of the line in fully simplified slope-intercept form is y = -x - 8.

How to find the equation of the line?

It is assumed that a line in the graph will pass through some points on the x and y-axes.

We must determine the line's fully simplified intercept.

we know the standard form of a line that is

y = mx + b

here, m is a slope and b is the constant

On the graph, there are the y-intercept (0,-8) and the x-intercept (-8,0).

The slope of the line passing through these points is:

[tex]slope = \frac{y2 - y1}{x2 - x1} \\ [/tex]

[tex]slope = \frac{ 8 - 0}{ 0 - 8} [/tex]

slope = 8/(-8)

slope = -1

then find the value of b

if x = 0 y = -8 then

y = mx +b

-8 = -1(0) + b

-8 = b

the value of b is -8

After inserting the values for m and c, the line's equation will be.

y = - x - 8

Hence y = -x - 8 is the equation of the line in fully simplified slope-intercept form.
