The coordinates of the points dividing the line in 5:3 is (3/2, 3)

The section formula gives the coordinates of a point which divides the line joining two points in a ratio, internally or externally.

Given a line LM, passing through points  (-1,-2) and (3,6) a point is dividing it in a ratio of 5:3

According to section formula,

(x, y) = (5*3 - 3*1)/8, (5*6 - 3*2)/8

(x, y) = (3/2, 3)

Hence, The coordinates of the points dividing the line in 5:3 is (3/2, 3)

The amount in grams of food A and B she feeds this group of rats each day will be 2200003.84 gm and 1100006.4 gm respectively.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

Given that, she provides a certain set of lab rats with a daily meal that contains exactly 32 units of niacin and 22000 units of retinol. She uses two different brands of industrial pellet food.

If food A has 100 units of retinol and 0,12 units of niacin per gram.Niacin 0.20 units and retinol 50 units are both included in Food B per gram. The grams of each food she feeds this group A of rats each day is,

=32×0.12+22000×100

=2200003.84 gm

If food B contains 0,20 units of niacin and 50 units of retinol per gram.The grams of each food she feeds this group A of rats each day is,

=32×0.20+22000×50

=1100006.4

Thus, the amount in grams of food A and B she feeds this group of rats each day will be 2200003.84 gm and 1100006.4 gm respectively.

Answer:

The fraction that shows the number of hours Saide's dog sleeps every 4 hours in a day is 1/6.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

It should be noted that there are 24 hours in day. Since the dog sleeps for 4 hours in a day, the fraction will be:

= Number of hours slept / Total hours

= 4 / 24.

= 1/6

Answer:

Step-by-step explanation:

Forming the equation,

→ 2x + 3 = -3x + 3

Now the value of x will be,

→ 2x + 3 = -3x + 3

→ 2x + 3x = 3 - 3

→ 5x = 0

→ x = 0/5

→ [ x = 0 ]

Then the value of y will be,

→ y = -3x + 3

→ y = -3(0) + 3

→ y = 0 + 3

→ [ y = 3 ]

Hence, the value of y is 3.

The statement of Gabriella, “The graph will not have an inverse function.” is incorrect. Option B is correct.

Let us understand about the given graph:

The given graph is a graph of a cube root function.

So, the statement of Noelle, “The graph represents the function [tex]f(x)=\sqrt[3]{x}[/tex]." is correct.

So, option A is not correct.

The inverse of a cube root function is a cubic function.

So, the statement of Gabriella, “The graph will not have an inverse function.” is incorrect.

So, option B is correct.

The domain and range of the cube root function are all real numbers.

So, the statement of Julian, “The domain and range of the function is all real numbers.” is correct.

So, option C is not correct.

From the graph, we can see f(-1) = -1.

So, the statement of Yemen, “The value of f(-1) = -1.” is correct.

So, option D is not correct.

Thus, the statement of Gabriella, “The graph will not have an inverse function.” is incorrect. Option B is correct.

[tex]\frac{1}{5}[/tex] b - 2a + [tex]\frac{1}{2}[/tex] b + 4a ← collect like terms

Applying the inscribed angle theorem, we have:

9. B. m∠ABC = 70°

10. F. m∠Z = 54°

11. According to the two-tangent theorem, x is: D. 8 m

An inscribed angle in a circle has a measure that is half of the measure of the intercepted arc, based on the inscribed angle theorem.

The two-tangent theorem states that if two tangents are drawn from a circle to meet at a point outside the circle, the two tangents are equal to each other.

9. Measure of arc AC = 360 - 120 - 100

Measure of arc AC = 140°

m∠ABC = 1/2(measure of arc AC) [inscribed angle theorem]

m∠ABC = 1/2(140)

m∠ABC = 70° [option B]

10. Arc XYZ = 2(m∠X) [inscribed angle theorem]

Arc XYZ = 2(126) = 252°

Arc WXY = 360 - arc XYZ

Arc WXY = 360 - 252

Arc WXY = 108°

m∠Z = 1/2(arc WXY) [inscribed angle theorem]

m∠Z = 1/2(108)

m∠Z = 54° [option F]

11. x = 10 - 2 [two-tangent theorem]

x = 8 m [option D]

The coordinates of the midpoint of segment FG are (3,-1) which was found using midpoint formula.

When it comes to practical application, the midpoint formula is rather straightforward.

Step 1: Determine the line segment or the two ends.

Step 2: Determine their coordinates.

Step 3: Add the x coordinates of both ends and divide by 2.

Step 4: Adding the y coordinates of both endpoints, divide by 2, and complete the step.

Step 5: As you specify the coordinates of any point, write the values that were acquired in Steps 3 and 4.

Given: Endpoints of a line segment are F(2, -1) and G(-8, -1).

We need to find the coordinates of its midpoint.

Using midpoint formula,

(a,b) = (x₁ + x₂)/2,(y₁ + y₂)/2

       = (2-8)/2,(-1-1)/2

       = 3,-1

So, coordinates are (3,-1)

Therefore, the coordinates of the midpoint of segment FG are (3,-1) which was found using midpoint formula.

well, we had a cylinder with 7mL of water, in the rock goes and kaboom the volume for the cylinder and its contents is 9 mL, well, the displaced water from the rock is equivalent to its volume, as Archimedes would properly point out, so since it was 7mL and now is 9mL well, the extra 2mL is the volume of the rock :).

sidenote:  Archimedes is Da Bomb!!!!

now, we know the rock weights 24 grams, and we also know its volume is 2mL, so its density is simply g/mL, or [tex]\cfrac{24g}{2mL}\implies 12~\frac{g}{mL}[/tex]

Answer:

  8.75

Step-by-step explanation:

You want the greatest possible x-coordinate of point A such that for any point B on the y-axis between (-24) and 25, the segment AB has a common point with the line segment PQ, where P(5, -12), Q(5, 9).

If we designate the points on the y-axis as X(0, -24) and Y(0, 25), we find that point A must lie in the triangle bounded by lines XY, XP, and YQ. The x-coordinate of the point of intersection of lines XP and YQ will be the greatest x-coordinate that point A can have.

The line through points (x1, y1) and (x2, y2) can be written as ...

  (y2 -y1)(x -x1) -(x2 -x1)(y -y1) = 0

This equation is readily simplified to general form ax+by+c = 0.

Line XP

  (-12-(-24))(x -0) -(5-0)(y -(-24)) = 0

  12x -5y -120 = 0

Line YQ

  (9 -25)(x -0) -(5 -0)(y -(25)) = 0

  -16x -5y +125 = 0

We want the value of x that satisfies these equations. That can be found by subtracting the second equation from the first:

  (12 -5y -120) -(-16x -5y +125) = (0) -(0)

  28x -245 = 0

  x = 245/28 = 8.75

The greatest x-coordinate is x = 8.75.

Note that because the graph is slightly deformed to the left, it is impossible to work out the exact bearing. Below, however, are steps on how to get the bearing of a map.

Calculate the angle clockwise from north to determine a bearing. Begin with the first site by drawing a vertical line symbolizing north. Draw a line from the starting point to the ending point. Calculate the clockwise angle formed by the north line and this line.

When measuring a bearing, three principles must be followed:

Note that a bearing is an angle in degrees calculated clockwise from north in mathematics. Bearings are often specified in three figures. 30° clockwise from north, for example, is generally represented as 030°.
