This question was incomplete. Here is the complete question:

Point W is located on QR so that QW/QR = 3/4. What are the coordinates of point W?

The picture of the question is attached herewith.

Answer:

The coordinates of W will be (9, 9)

Step-by-step explanation:

This question can be solved using the concept of similar triangles. In similar Triangles the ratio of the LENGTHS of their corresponding sides is equal.

So firstly we will complete the triangle by drawing a horizontal and vertical line joining at P. The coordinates of P will be (11, 3). The length QP will be 8 units. The length PR will be 8 units as well. This has been drawn for you in the diagram attache.

Next we will mark any point on line QR as W. The distance of W from Q is taken as x and the vertical distance of W from QP is taken as y.

Now using the similar triangle ratio rule.

The side represented by x is corresponding to side QP so:

x/8 = 3/4

x = 6

Similarly the side represented by y is corresponding to side PR.

y/8 = 3/4

y = 6  

Adding these lengths with the starting coordinate of Q(3, 3) to find the value of coordinates of W.

So 3+6 = 9 is the x coordinate of W and

3 + 6 = 9, is the y coordinate of W

W = (9, 9) ANS

Another way to do this is divide by 6 and multiply by 100

Answer:

The answer is C) (-1,4) ;)

Step-by-step explanation:

Exponential

Step-by-step explanation:

So let’s start off by looking at how much x is growing by each time

X is growing by 8 each time

Next look at how much y is growing by

-6 to -24 is a difference of 18

-24 to -96 is a difference of 72

And lastly -96 to -384 is a difference of 288

So we can now say that it is not linear because a linear equation grows by a constant number (like adding)

To determine if it is exponential see if it is growing by a constant multiplier

24 divided by 6 is 4

96 divided by 24 is 4

384 divided by 96 is 4

It is exponentially growing by 4

Answer: D

Step-by-step explanation:

Multiply 2 times 3.14 times the radius, which is half the diameter. So divide 9 in half to get 4.5 as the radius. 2 times 3.14 times 4.5 equals 28.29. Round up to the nearest tenth equaling 28.3.

Given:

The given equation is [tex]x^{2} -3x-7=0[/tex]

We need to determine the exact solutions of the equation.

Exact solution:

The exact solution of the equation can be determined by solving the equation using quadratic formula,

[tex]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]

From the equation the values are a = 1, b = -3 and c = -7

Thus, substituting these values in the equation, we get;

[tex]x=\frac{-(-3) \pm \sqrt{3^2-4(1)(-7)}}{2(1)}[/tex]

[tex]x=\frac{3 \pm \sqrt{9+28}}{2}[/tex]

[tex]x=\frac{3 \pm \sqrt{37}}{2}[/tex]

Thus, the exact solutions of the given equation is [tex]x=\frac{3 \pm \sqrt{37}}{2}[/tex]

Hence, Option A is the correct answer.

Answer:

The value of the expression modeled by the decimal grids is 4.13

Step-by-step explanation:

Question is incomplete (the decimal grids are missing; see attachment for complete question).

Few points to be noted when reading a decimal grid are.

1. The scale of the grid

2. The ratio of the shaded region to the whole region

3. A fully shaded grid represent 1.

The scale of the grids in this question is a 10 x 10 grid.

10 * 10 = 100

Meaning that there are 100 squares in a grid

Having said this, well proceed to getting the decimal value of each individual grids.

For grids before the addition sign (+)

The first grid is fully shaded; so, it'll be represented with 1

The second grid is also fully shaded; thus, it'll also be represented with 1

The third grid has some of its region shaded; 23 of the 100 squares are shaded.

So, the third grid = 23/100 = 0.23

The Summation of the grids before the addition is 1 + 1 + 0.23 = 2.23

We move to the grids after the addition sign.

The first grid is fully shaded; so, it'll be represented with 1.

The second grid has some of its region shaded; 90 of the 100 squares are shaded.

So, the second grid = 90/100 = 0.90

The Summation of the grids after the addition sign is 1 + 0.90 = 1.90

Now, we can properly represent the grids in decimal forms.

This will be represented as

2.23 + 1.90

And that's equal to

4.13

Hence, the value of the expression modeled by the decimal grids is 4.13

Answer:

The diameter is 24 so the radius is 12 then we do pi*r^2 or pi*12^2

We can use our numbers and get pi*144 so the area of the circle is 144pi.

If they have given you what pi is

EX:( 22/7 or 3.14)

Just use that instead of pi and multiply 144 to that

Answer:

-8/3

Step-by-step explanation:

We know that lines that are perpendicular have slopes that multiply to -1

m1 * m2 = -1

We know one slope is 3/8 and are looking for the perpendicular slope m2

3/8 * m2 = -1

Multiply each side by 8/3 to find m2

3/8*8/3 *m2 = -1*8/3

m2 = -8/3

Final answer:

The number that best represents a positive charge of 1,350 is B. 1,350. Positive charges are indicated by numbers without a negative sign and the magnitude of charge is always represented as a positive value.

Explanation:

The number that best represents a positive charge of 1,350 is B. 1,350. Positive charges are indicated by numbers without a negative sign. As the question specifies a positive charge, the correct choice is the one without a minus in front of the number, therefore, option B is correct. This choice directly corresponds with the charge being positive, as indicated in the options provided.

It is important to note that the magnitude of charge is independent of its type, meaning that the numerical value of a charge represents its magnitude and is always positive, irrespective of whether the charge itself is positive or negative. An example in physics would be the charge of an electron which is -1.602 × 10-19 C, whereas a proton has a charge of +1.602 × 10-19 C, both having the same magnitude of charge but different signs.

Answer:

[tex](x-9.291)\cdot (x + 1.292)[/tex]

Step-by-step explanation:

The factors of the given polynomial ([tex]x^{2}-8\cdot x - 12[/tex]) are derived from the General Formula for Second-Order Polynomials:

[tex]x = \frac{8 \pm \sqrt{64 - 4\cdot (1)\cdot (-12)}}{2\cdot (1)}[/tex]

[tex]x_{1} \approx 9.291[/tex] and [tex]x_{2} \approx -1.292[/tex]

The factors of the polynomial are:

[tex](x-9.291)\cdot (x + 1.292)[/tex]

Answer:

The answer is prime.

Step-by-step explanation:

x2 – 8x – 12

We need two numbers which are factors of 12 such that their product is -12 and their sum is -8. The factors are 1, 2, 3, 4 and 6 but no two numbers satisfy the requirements of summing up to -8 and product of -12.

Therefore the equation is a prime as it has no factor

We can also check if the equation has a factor using the formula for general quadratic equation of ax² + bx + c = 0, the formula is;

(b² - 4ac)

If the answer is a perfect square only then we can factorize the equation.

In the given equation x² - 8x - 12

b = -8 and c = -12

b²- 4ac = (-8)² - 4(1)(-12) = 64 + 48 = 112

Since 112 is not a perfect square number, we can say there is no factors for the given equation.

Step-by-step explanation:

The opening is a rectangle. The length of diagonal AC can be found using the Pythagorean theorem using the lengths of AB and BC. The length of diagonal BD can be found using the Pythagorean theorem using the lengths of BC and CD.

To determine if the opening is a rectangle, we need to compare the lengths of the opposite sides. If the lengths are equal, then it is a rectangle. In the diagram, we can see that AB and CD are equal, as well as AD and BC. Therefore, the opening is a rectangle.

To find the length of the diagonals, we can use the Pythagorean theorem. The diagonal AC is the hypotenuse of triangle ABC, and the diagonal BD is the hypotenuse of triangle BCD. We can calculate the lengths as follows:

AC = √(AB2 + BC2)

BD = √(BC2 + CD2)

Answer:

First Option is correct.

Step-by-step explanation:

Since we have given that

Measure of arc WZ = 175°

Measure of ∠XAZ = 105°

We need to find the measure of ∠XYZ.

As we know the angle subtended at the center is the average of the measure of arc intercepted by it angle and its vertical angles.

Hence, the value of  ∠XYZ is 35°.

Hence, First Option is correct.

Answer:

35°

Answer:

uhh sorry man no can do

Step-by-step explanation:

Answer:

x = 7

Step-by-step explanation:

An inscribed angle represents half of its intercepting arc. So what I did was add [tex]19x + 13[/tex] and [tex]90[/tex] which comes to [tex]19x + 103[/tex]

Angle Q would be half of [tex]19x + 103[/tex].

[tex]Q = \frac{19x +103}{2}[/tex]

The opposite of Q is [tex]7x + 13[/tex].

I will call this angle "y" just to explain.

y + Q = 180

This means we just have to plug everything in.

[tex]7x + 13 +\frac{19x + 103}{2} = 180[/tex]

Solve for x.

[tex]7x +\frac{19x + 103}{2} = 167[/tex]

[tex]2(7x +\frac{19x + 103}{2}) = (167)2[/tex]

[tex]14x +19x +103 = 334[/tex]

[tex]33x = 231[/tex]

[tex]x = 7[/tex]
