The triangle with vertices located at R(-6 , 4), S(-2 , -2), T(2 , 4) has its centroid located at (-2 , 2).

The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.

To get the centroid of a triangle, use the formula given by:

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

where C is the centroid of the triangle located at (x , y)

x1, x2, and x3 are the x-coordinate of the vertices of the triangle

y1, y2, and y3 are the y-coordinate of the vertices of the triangle

Let Point 1(x1 , y1) = R(-6 , 4)

Point 2(x2 , y2) = S(-2 , -2)

Point 3(x3 , y3) = T(2 , 4)

Plug in the values in the formula.

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

C(x ,y) = [(-6 + -2 + 2)/3 , (4 + -2 + 4)/3]

C(x ,y) = (-6/3 , 6/3)

C(x ,y) = (-2 , 2)

The distance between the two points ( − 4 , - 5 ) and ( 0 , 5 ) is 10 units.

We are given the two points:

( − 4 , - 5 ) and ( 0 , 5 )

We need to find the distance between the two points.

The formula for distance is given as:

Distance = √ (x₂ - x₁)² + (y₂ - y₁)²

Substituting the values, we get that:

Distance = √ ( 0  + 4 )² + ( 5 + 5)²

Distance = √ ( 4 )² + ( 10 )²

Distance = √ 16 + 100

Distance = √ 116

Distance = 2 √29 units.

Therefore, we get that, the distance between the two points ( − 4 , - 5 ) and ( 0 , 5 ) is 2 √29 units.

The ounces of cat food she will feed her cat in 4 weeks is 54.4 oz

The given parameters are

1 oz = 28.3 g

1 day = 55 g

For 4 weeks, the amount would be

1 * 7 * 4 days = 55 g * 4

So, we have

28 days = 1540 g

Rewrite as

4 weeks =1540 g

The probability of selecting a 5 and the coin landing on head is 1/26

In this question, a card is drawn at random from a standard pack of playing cards and fair coin is flipped.

Here, we have two different sample spaces to work with and we want to calculate a compound probability.

Firstly in a deck of cards which contain a total of 52 cards, there are 4 cards labeled 5.

So, the probability of selecting a 5 is:

4/52 = 1/13

Also, in a flip of coin the probability of the coin landing on head is 1/2

Thus the probability of selecting a 5 and the coin landing on head would be,

probability of selecting 5 × probability of the coins landing on head

= 1/13 × 1/2

= 1/26

Therefore, the probability of selecting a 5 and the coin landing on head is 1/26

Work for 30 hours in a week $10 per hour

The domain and the range for the given situation will be:

Domain = [0, 30]

Range = [0, 300]

Given that Josie earns $10 per hour at her job. Her hours vary, but she never works more than 30 hours in any given week,

We need to find the domain and range.

In this situation, the domain refers to the possible values for the input variable, which is the number of hours Josie works in a given week.

The range, on the other hand, refers to the possible values for the output variable, which is her earnings for the week.

For the domain:

Since Josie never works more than 30 hours in any given week, a reasonable domain for this function would be from 0 to 30 hours. We don't consider negative hours (as it doesn't make sense in this context), and the upper limit is set by her maximum weekly working hours.

Domain = [0, 30]

For the range:

The range should be the possible earnings Josie can make in a week based on her hourly rate of $10 per hour.

To find the range, we multiply her hourly rate by the maximum number of hours she can work in a week, which is 30 hours.

Range = [0, 10 x 30] = [0, 300]

So, the function that represents Josie's possible earnings for one week is:

Earnings = f(hours) = 10 x hours

Where "hours" is the number of hours she works in a week, and "Earnings" is the corresponding amount she earns.

The graph of this function will be a straight line passing through the origin (0, 0) and with a slope of 10, representing her earnings increasing linearly with the number of hours worked.

The line will extend up to the point (30, 300) and then flatten out as she cannot earn more than $300 in a week.

Answer

Domain: 1 < x < 5

Range: -10 < y < 2

Step-by-step explanation

First, we need to graph the function. The function is just a linear function, but arranged differently. You can rearrange it to be:

[tex]f(x) = -3x + 5[/tex]

Now graph the function. The slope of it should be -3, and the y-intercept is 5.

To find the domain, just use the relation of the x values given with the function (1 < x < 5).

To find the range, plug the smallest and largest values of the domain into the function given. 1 and 5 should be the numbers you are plugging in. The outputs will be the range. Remember that negative numbers are smaller than positive numbers, so the negative number should be on the left.

If yacht is sailed from A to B on a bearing of 196ºT, the true bearing to sail directly back to point A from point B is 16° T.

To determine the true bearing from point B back to point A, we need to consider the relationship between true bearings and the reciprocal direction.

Given that the yacht is sailed from point A to point B on a bearing of 196° T (True), the reciprocal direction would be the opposite direction, 180° away on the compass.

Thus, to sail directly back to point A from point B, we would need to subtract 180° from the reciprocal direction.

x = 74 degrees is the angle

Let x = the angle

then

(180-x) is the supplement of x

and

(90-x) is the complement of x:

"The supplement of an angle is 26 more than 5 times its complement."

(180-x) = 26 + 5(90-x)

180 - x = 26 + 450 - 5x

-x + 5x = 26 + 450 - 180

4x = 296

x = [tex]\frac{296}{4}[/tex]

x = 74 degrees is the angle

5 times its complement.

(180-74) = 26 + 5(90-74)

106 = 26 + 5*(16)

106 = 26 + 80; confirms our solution

In  elementary geometry , an angle  is that the  figure formed by two rays, called  the edges  of the angle, sharing  a standard  endpoint, called the vertex of the angle. Angles formed by two rays  dwell  the plane that contains the rays. Angles also are  formed by the intersection of two planes. These are called dihedral angles. Two intersecting curves  can also  define an angle, which  is that the  angle of the rays lying tangent to the respective curves at their point of intersection.

Angle is additionally  used to designate the measure of an angle or of a rotation. This measure  is that the  ratio of the length of a circular arc to its radius.  within the  case of a geometric angle, the arc is centered at the vertex and delimited by  the edges .  within the  case of a rotation, the arc is centered at  the middle  of the rotation and delimited by any other point and its image by the rotation.

Potentially, an angle denoted as, say, ∠BAC, might  ask  any of four angles: the clockwise angle from B to C, the anticlockwise angle from B to C, the clockwise angle from C to B, or the anticlockwise angle from C to B, where the direction  during which  the angle is measured determines its sign (see Positive and negative angles).

Given that,

(2.3[tex]\times[/tex]10⁵)(1.5 [tex]\times[/tex]10⁴)

By using scientific notation

The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.

Now, we calculate

(2.3[tex]\times[/tex]10⁵)=2.5[tex]\times[/tex]100000=230000

(1.5 [tex]\times[/tex]10⁴)=1.5[tex]\times[/tex]10000=15000
