Segment BDSegment BD is a perpendicular bisector of segment ACsegment AC . AD=8x−15AD=8x−15 and DC=57DC=57 .

What is the value of x?

Answers

Answer 1
Since BD is a perpendicular bisector of AC, then ADC forms an isisceles triangle with AD = DC.
Thus 8x - 15 = 57
8x = 57 + 15 = 72
x = 72/8 = 9.

Answers

Based on the given values above, according to my research, the magnitude of the size change of the figures formed by the matrices given would be 2. Hope this is the answer that you are looking for. Thanks for posting your question in brainly.
Answer:

The magnitude of the size change of the figures formed by these matrices is:

                                         2

Step-by-step explanation:

We are given a  first matrix as:

           [3   -2   1]

and second matrix is given by:

            [6   -4   2]

Since we could clearly observe that when we multiply first matrix by a constant 2 then we obtain a second matrix.

   i.e.   2[3 -2 1]=[2×3   2×(-2)   2×1]

                        = [6   -4   2]

   Hence, the change in the magnitude of the size of two matrices is:

                             2

Find the values of x and y that maximize the objective function P=3x+2y for the graph. What is the maximum value? Show all work.

Answers

Since coeficient in front of x is larger than coeficient in front of y that means that value of function P  depends more on x than on y. That means that we should look for highest posible x and see highest posible y for that x.

Highest x value is 9 and we can only pick y=0 for it

P = 27

Note that if u decrease x by 1 we can take y=1 but now our value is:
P = 8*3 + 2*1 = 26 which is just confirmation why P depends more on x than on y due to coefficient in front of x.

Step-by-step explanation:

To find the maximum, input the vertices (0,8), (5,4) and (9,0) into the objective function (P = 3x + 2y) to determine which vertex obtains the maximum value.

NOTE: I don't understand why (5,4) was given on your graph as a vertex.

(0,8): P = 3(0) + 2(8)  = 0 + 16   = 16

(5,4): P = 3(5) + 2(4)  = 15 + 8   = 23

(9,0): P = 3(9) + 2(0)  = 27 + 0   = 27      THIS IS THE LARGEST (MAX) P-VALUE

what is the expression in factored form 16x^2+8x

Answers

Final answer:

The expression 16x^2+8x in factored form is 8x(2x + 1), obtained by factoring out the greatest common factor, which is 8x.

Explanation:

To factor the expression 16x^2+8x, we look for common factors in each term. Here, we can see that both terms contain a power of x and the number 8 is a common factor. We can factor out 8x from each term.

Step-by-step, this looks like:

Identify the greatest common factor (GCF): both terms have an x and an 8 in common.Factor out the GCF: 16x^2 + 8x = 8x(2x + 1)

We've now expressed the original expression in factored form.

Use π = 3.14.

What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.

Answers

OK once you do the math and find the volume of the cone it comes out to 150.8
and the cylinders volume comes out to 301.6  the relationship between them is that the the cones volume is 2x smaller than the cylinders volume so two cones would equal one cylinder.

the cone = 150.8

the cylinder= 301.6   the cones volume is 2x smaller than the cylinders volume. two cones equal one cylinder.

Let the amount of Brand Y = 1 kg.
Thus the amount of Brand X = (1 kg)(1.20) = 1.20 kg

Let the price of Brand Y = $1.
Thus the price of Brand X = ($1)(0.90) = $0.90.

Hence, the unit price of Brand X is $0.90 / 1.20 kg = $3/4 /kg and the unit

A department store has a discount on shoes based on a percentage of the price suppose one pair of shoes is marked down from $70 to $49 what is the price for a $100 pair of shoes after the discount is applied

Answers

We first need to find the difference between $70 and $49.
$70 - $49 = 21

Now we find out what percent $21 is of $70.
21/70 × 100 = 30%.

That means the discount is 30%!

Now we must find 30% of $100, which is $30.

Then we subtract $30 from $100.

$100 - $30 = 70$

In the diagram below, G is the incenter of DEF. m
In the previous question, what is m

Answers

Final answer:

The question involves Physics concepts such as vector addition, moment of inertia, and gravitational force calculations. The incenter mentions seem irrelevant to the Physics calculations related to inertia and force.

Explanation:

The question asked is about calculating the moment of inertia for a specific geometric object (a cylinder) and involves understanding the mass distribution relative to an axis of rotation. This is a common concept in the field of Physics, particularly when dealing with rotational dynamics and inertia.

The mention of the incenter of a triangle appears to be unrelated to the main question, which is more focused on moments of inertia, vector addition, and gravitational force equations as indicated by the provided reference information.

For example, the moment of inertia of a cylinder about a given axis can be calculated using established mathematical formulas. Moreover, vector addition (such as Đ = Ả + 2B - F) includes principles such as scaling, displacement and direction, which are crucial in Physics for predicting the outcomes of combined vector forces.

Lastly, the reference to the mass m of an object cancelling in the equation for g is related to calculating the acceleration due to gravity on Earth, which does not depend on the mass of the falling object.

Final Answer:

In the previous question, m represents the measure of an angle, and without specific information about which angle in Δ DEF is being referred to, a precise value cannot be determined.

Explanation:

The symbol m in geometry typically denotes the measure of an angle. In the context of the given diagram, G being the incenter of Δ DEF suggests that G is the point where the angle bisectors of the triangle intersect. However, to determine the specific measure (m) of an angle, additional details about which angle in Δ DEF is being considered are required.

In geometry, the measure of an angle can vary based on its location within a triangle. The incenter is where the angle bisectors meet, ensuring that the angle formed by connecting G to the vertices of Δ DEF is bisected equally. Without information about the specific angle being referenced, a numerical value for m cannot be provided.

Understanding angle measures and the role of an incenter in bisecting angles is crucial in geometry. Precision in describing angles requires clarity on the specific angle under consideration, allowing for accurate calculations and conclusions.

Identify the correct slope and y intercept of the equation 2x + 4y = 12.
How would I do this?

slope = 2; y intercept at (0, 12)

slope = 1/2; y intercept at (0, 3)

slope = 1/2; y intercept at (0, 4)

slope = -1/2; y intercept at (0, 3) ...?

Answers


The standard form of a line is an easy way to solve for the properties of a line, such as slope and the intercepts. Take a line with the equation in standard form,

Ax + By = C

The slope here is given by y = -A/B.
The x-intercept here is given by (C/A, 0).
The y-intercept here is given by (0, C/B).

For this problem, the equation is 2x + 4y = 12. Thus,
slope = -2/4 = -1/2
y-intercept = (0, 12/4) = (0, 3)

The table shows the amounts of food collected by two homerooms. Homeroom A collects 21 additional items of food. How many more items does Homeroom B need to collect to have more items per student Homeroom A Homeroom B

Students 24 16
Canned Food 30 22
Dry Food 42 24

Answers

The number of food items Homeroom B needs to collect to have more food items per student than Homeroom A is 16

How many more items does Homeroom B need to collect to have more items per student?

Food items collected by homeroom A:

Canned food = 30

Dry food = 42

Additional food items = 21

Number of students = 24

Food items per students = (30 + 42 + 21) / 24

= 93/24

Food items collected by homeroom B:

Canned food = 22

Dry food = 24

Additional food items = x

Number of students = 16

Food items per students = (22 + 24 + x) / 16

= (46 + x) / 16

Number of more food items Homeroom B need to collect to have more items per student than Homeroom A:

(46 + x) / 16 > 93/24

cross product

(46 + x) × 24 > 16 × 93

1,104 + 24x > 1,488

24x > 1,488 - 1,104

24x > 384

Divide both sides by 24

x > 384/24

x > 16

Homeroom B needs to collect at least 17 more items to exceed Homeroom A in items per student. The calculation is based on the total food items and the number of students in each homeroom.

To find out how many more items Homeroom B needs to collect to have more items per student than Homeroom A, we will first calculate the items per student for each homeroom, considering that Homeroom A collects 21 additional items.

First, calculate the total items of food collected by each homeroom:

Homeroom A:

- Canned food: 30 items

- Dry food: 42 items

- Additional items: 21 items

Total items for Homeroom A:

30 + 42 + 21 = 93 items

Number of students in Homeroom A: 24

Items per student in Homeroom A:

[tex]\[\frac{93}{24} \approx 3.875 \text{ items per student}\][/tex]

Homeroom B:

- Canned food: 22 items

- Dry food: 24 items

Total items for Homeroom B:

22 + 24 = 46 items

Number of students in Homeroom B: 16

Items per student in Homeroom B:

[tex]\[\frac{46}{16} = 2.875 \text{ items per student}\][/tex]

Determine additional items needed for Homeroom B:

Let ( x ) be the additional items needed for Homeroom B to exceed Homeroom A's items per student.

The new total items for Homeroom B would be:

46 + x

The new items per student for Homeroom B would be:

[tex]\[\frac{46 + x}{16}\][/tex]

We need this to be greater than Homeroom A's items per student:

[tex]\[\frac{46 + x}{16} > 3.875\][/tex]

Solving for ( x ):

46 + x > 3.875 × 16

46 + x > 62

x > 62 - 46

x > 16

Thus, Homeroom B needs to collect more than 16 additional items to have more items per student than Homeroom A.

In conclusion, Homeroom B needs to collect at least 17 more items to exceed Homeroom A in items per student.
