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

Answer:

There are 24 children living on the street. There are 18 pets living on the street.

Step-by-step explanation:

The answer is 24 chilren because you have to multiply the amount of children and the amount of houses in the street. When you do that you get 24.

There are 18 pets living on the street because in total 3 pets are living in EACH house. 6×3=18.

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:

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:

y=|6x-2|-3

Step-by-step explanation:

I can see y=|x-1/3|-3 is a tempting answer, it does have its vertex at (1/3,-3) but it doesn't go through (1,1). This graph needs to be steeper, so we need to multiply x and the -1/3 coefficient next to it.

We multiply x and -1/3 each by 6, and boom! The graph goes through (1,1) and the vertex is still maintained at (1/3,-3) The -3 outside of the function doesn't change because the vertex's y-coordinate is -3, so it must stay the same.

The formula for the absolute value function with the vertex at ([tex]\frac{1}{3}[/tex], -3) and passing through (1, 1) is f(x) = 6|x - [tex]\frac{1}{3}[/tex]| - 3.

To write the formula for an absolute value function with a given vertex and point, we can use the standard form of an absolute value function, which is f(x) = a|x - h| + k, where (h, k) is the vertex of the function. In your question, the vertex is at the point ([tex]\frac{1}{3}[/tex], -3) and the function passes through the point (1, 1).

We can start by substituting the vertex into the formula, which gives us f(x) = a|x - [tex]\frac{1}{3}[/tex]| - 3. To find the value of 'a', we use the fact that the function also passes through the point (1, 1). Substituting x = 1 into the formula gives us 1 = a|1 - [tex]\frac{1}{3}[/tex]| - 3 → 1 = a([tex]\frac{2}{3}[/tex]) - 3 → a = 6. So, the function formula is f(x) = 6|x - [tex]\frac{1}{3}[/tex]| - 3.

Step-by-step explanation:

The central angles determined by the congruent chords are equal in measure, thus

∠ BOC = ∠ BOA = 43° → B

The measure of BOC is 43°.

In geometry, two figures or gadgets are congruent if they have identical shapes and sizes, or if one has an equal shape and size as the replicated picture of the alternative.

The word 'congruent' method 'precisely same' in phrases of shape and length. Even if we turn, turn, or rotate the shapes, they stay identical. for example, draw two circles of the equal radius, then reduce them out and region them on one another.

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:

[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.

Answer:

m∠1=21°, m∠2=159°, m∠3=21°, m∠4=159°

Step-by-step explanation:

All of the angles added up = 360°

We know that angles 2 and 4 are the same, due to angle rules.

If all of the angles, added up, equal 360, and angles 2 and 4 are equal, we have an equation. Note: m∠2=159°

HOPE THIS HELPED! Brainliest??

Given that m∠2=159∘, any vertical angle to it will also measure 159∘. Use the angle sum property of triangles to calculate any other angle in a triangle.

To find the measure of all the angles in the diagram, you'll have to use your understanding of angle relationships. Since you've been provided that m∠2=159∘, you can use this to calculate the measures of the rest. When dealing with a pair of vertical angles, remember that they are equal. Therefore, if m∠2=159∘, then its vertical angle will also measure 159∘. Also, using the angle sum property of triangles, which states that the sum of all interior angles of a triangle sum to 180∘, you can calculate the missing angles if the diagram indicates a triangle.

Answer:

a=3    b=6

Step-by-step explanation:

The cube root of 162 has been factored into the cube root of 27 and the cube root of 6. The simplest form is thus 3 times the cube root of 6, so a = 3 and b = 6.

The student is working on finding the cube root of 162 and has already correctly factored this into the cube root of 27 times the cube root of 6. To simplify this, we recognize that 27 is a perfect cube (3³), so the cube root of 27 is 3. Therefore, the simplest form of ∛162 can be written as:

∛162 = ∛27 × ∛6

This simplifies to:

3 × ∛6

Where the ∛ symbol represents the cube root. As such, in the form ∛a∛b, where 'a' is the cube root of a perfect cube and 'b' is the remaining factor, we have a = 3 and b = 6 for this equation.

162 was factored into a product of 27 (a perfect cube) and 6, which cannot be further simplified in terms of cube roots.

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
