Which of these relations is a function?
I’m I correct??

Given:

Point C divides AB such that AC:BC=2:3.

To find:

The x-value for point C.

Solution:

Section formula: If a point divide a line segment in m:n, then

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Form the given graph it is clear that the endpoints of the line segment AB are A(-3,5) and B(3,0).

Point C divides AB such that AC:BC=2:3. Using section formula, the coordinates of point C are

[tex]C=\left(\dfrac{2(3)+3(-3)}{2+3},\dfrac{2(0)+3(5)}{2+3}\right)[/tex]

[tex]C=\left(\dfrac{6-9}{5},\dfrac{0+15}{5}\right)[/tex]

[tex]C=\left(\dfrac{-3}{5},\dfrac{15}{5}\right)[/tex]

[tex]C=\left(-0.6,3\right)[/tex]

The x-value of C is -0.6.

Therefore, the correct option is B.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let us represent

Let the wood bat = w

Let the base ball bats = b

Savelot offers two types of baseballs bats the wood bat sell for 24$ and the metal bats sell for 30 in one day save lots sold 23 base ball bats these recipts for those bats totaled $606 how many of each type of bat was sold

System of Equations

w + b = 23.... Equation 1

b = 23 - w

24w + 30b = 606..... Equation 2

We substitute:30 - w for b

Hence:

24w + 30(23 - w) = 606

24w + 690 - 30w = 606

24w - 30w = 606 - 609

-6w = -84

w = -844/-6

w = 14 wood bats

b = 30 - 14

b = 16 base ball bts

The given triangle is a right triangle because it agrees Pythagoras theorem.

In the given triangle, the shorter lengths are 12 and 16.

The sum of square of shorter lengths:

[tex]= 12^2 + 16^2[/tex]

[tex]=144+256[/tex]

[tex]=400[/tex]

The longer length is 20.

Square of the longest length is [tex]20^2.[/tex]

[tex]20^2 = 20 \times 20[/tex]

=400

The sum of squares of shorter lengths is equal to Square of the longest length which obeys Pythagoras theorem.

400 = 400

As this is agreeing Pythagoras theorem it is a right angle triangle.

Hence, option B is correct. right triangle.

Step-by-step explanation:

Answer: (6, 6)

In this problem the point is moved over 2 up and 2 to the right form A to A'

The coordinates of B' are (-4, 6).

A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation may alternatively be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.

Since (ABCD) = (A'B'C'D'), we know that corresponding points in the two quadrilaterals have equal coordinates.

Therefore, we can use the coordinates of A and A' to find the translation vector that takes A to A'.

We can then apply this same vector to B to find its image B'.

The translation vector that takes A to A' is given by the difference A' - A:

A' - A = (-2, 4) - (6, -8) = (-8, 12)

So, the same translation vector takes B to B', and we have:

B' = B + (-8, 12) = (4, -6) + (-8, 12) = (-4, 6)

Therefore, the coordinates of B' are (-4, 6).

The magnitude of resultant force is 43.95 pounds.

The option c is correct.

Two forces are given that,

The resultant force is calculated by using formula,

         [tex]F=\sqrt{F_{1}^{2}+F_{2}^{2}+2F_{1}F_{2}cos \theta } \\\\F=\sqrt{25^{2}+20^{2}+2*25*20*cos25 }\\\\F=\sqrt{625+400+906.307}\\ \\F=\sqrt{1931.307}=43.95[/tex]

Incorrect

Step-by-step explanation:

This is incorrect. In order to add two fractions that have unlike denominators, it is true that you first need to find a common denominator. When you change a fractions denominator you must also change it's numerator in proportion to the change in the denominator. For example, if you change the denominator in the fraction [tex]\frac{1}{2}[/tex] into a 4 then you are multiplying the denominator by 2, therefore you will also need to multiply the numerator by 2 which would give you a new fraction of [tex]\frac{2}{4}[/tex]

Answer: Substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.

Step-by-step explanation:

I guess that we are working with systems of equations like:

y = f(x)

y = g(x)

Where an intersection is a solution that works for both equations, which means that the graphs will intersect each other in that point.

This means that for a given value x = x0, we must have:

f(x0) = g(x0).

Now, when you find a point that you think that is an intersection, you should substitute the x value in both functions, and see if the y-values coincide.

This will be equivalent to look if f(x) = g(x) for that particular value.

then the correct option is:

substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.

Given:

Lamar drinks water with,

Breakfast = 8 ounces

Vitamins = 6 ounces

Lunch = 16 ounces

Dinner = 16 ounces

Bottle = 32 ounces

To find:

The a numerical expression for the amount of water in ounces that he drinks in a week.

Solution:

One day consumption of water by Lamar is

[tex]8+6+16+16+32=78[/tex]

We know that,

1 week = 7 days

One day consumption of water = 78 ounces

1 week (7 days) consumption of water = 7× One day consumption of water

                                                               = 7×(8+6+16+16+32) ounces                                                                

                                                               = 7×78 ounces

                                                               = 546 ounces

Therefore, the required numerical expression for the amount of water in ounces that he drinks in a week is 7×(8+6+16+16+32) ounces and the value is 546 ounces.
