Answer:

y = 2/3x - 4

Step-by-step explanation:

To convert the equation \(3y = 2(x - 6)\) into slope-intercept form (\(y = mx + b\)), where \(m\) is the slope and \(b\) is the y-intercept, follow these steps:
1. Distribute the scalar on the right-hand side of the equation to both terms within the parentheses:
  \(3y = 2x - 12\)
2. Isolate the variable \(y\) on one side by dividing the entire equation by 3:
  \(y = \frac{2}{3}x - 4\)
Now the equation is in slope-intercept form, where the slope \(m\) is \(\frac{2}{3}\) and the y-intercept \(b\) is \(-4\). The final equation is:
\[y = \frac{2}{3}x - 4\]

Answer:

The correct answer is option B.  756 units²

Step-by-step explanation:

Points to remember

Surface area of pyramid = Base area  + (4 * area of side triangle)

To find the base area

Base area = side * side

 = 14 * 14 = 196 units²

To find the area of side triangle

Area of triangle = bh/d

Area = (14 * 20)/2 = 140 units²

To find the surface area of pyramid

Surface area = Base area  + (4 * area of side triangle)

 = 196 + (4 * 140)

 = 756  units²

Answer: 756

Step-by-step explanation:

point-slope formula is y-y1=m(x-x1)

y1 and x1 are coordinates, aka a point

The answer ur looking for is B

We know that functions are mathematical entities that assign unique outputs to given inputs. In other words, a function can't have repeated values in the input repeated x-value.

For example consider the relation {(1,4), (1,5), (2,6), (3,7), (4,8), (5,9)}.

We see that above relation has repeated x-value "1" which is assigned to two different output values 4 and 5. So by definition of function, above relation can't be a function.

Answer:

Step-by-step explanation:

Write down what you have for each pizza size.

small: s

Medium: (3/2) s

Large: (5/2) s

The only way I can see to do this is

s = L - M

s = 5/2 s  -   3/2 s

s = 2/2 s

This of course is not exactly what you are looking for. There is no explicit formula that will tell you exactly how much dough is in a small pizza.

See the comment below posted by SqdanceFan. He is saying that M/L = (3/2)//(5/2) = 3/5

Also (M)/( S + M)  =  3/5

But neither gives you an explicit formula for small, but it is a relationship. The fact that equality is achieved when both are zero is also true, but it does not solve the question. I don't think there's a good answer to this question.

Answer:

Step-by-step explanation:

If you are given  3.14 · 1.5 · 1.5, you actually have 3.14 · 1.5²

If you match this up to the area-of-a-circle formula A = πr²

you can see right away that r = 1.5.  If r = 1.5, d = 2(1.5) = 3.0

I do not quite understand what you were trying to present in your

"And the other is the area 3.14•3

2) 3.14•1.25" so am unable to help you with it.

To find the diameter and radius of a circle, divide the given circumference by 3.14 to find the diameter, and then divide the diameter by 2 to find the radius. To calculate the area, use the formula A = πr², where π is approximately 3.14 and r is the radius of the circle.

To find the diameter and radius of a circle, we need to understand the formulas and calculations involved. The diameter is the distance across the circle passing through the center, and it is twice the length of the radius. The radius is the distance from the center of the circle to any point on its edge.

Finding the Diameter and Radius:

So, depending on the given values, you can use the formulas mentioned above to solve for the diameter and radius of a circle.

Calculating the Area:

Using the formulas and steps above, you can find the diameter, radius, and area of a circle based on the given values.

Answer:

480 in

BTW: Who could be that tall other than "Jonathan" of course?

Step-by-step explanation:

If you use subtraction...

6514-6034=480

to solve this problem subtract 6034 from 6514 to get 480

So he grew 480 inches which is equivalent to 40 feet

Answer: k = 11%

Step-by-step explanation:

The relative frequency fr is calculated by dividing the frequency xi of a given Class by the number of total data.

[tex]fr = \frac{xi}{n} * 100\%[/tex]

In this problem there are 4 Class U ^ V and S ^ T

Notice in the first table that the total number of data is n = 19.

The relative frequency of k will be the frequency of T ^ V between the total number of data.

Notice in the first table that the frequency of the Class T ^ V is 2.

So

[tex]k = \frac{2}{19} * 100\%\\\\k = 11\%[/tex]

Answer:

B=11%

Step By Step EXP.

Step-by-step explanation:

Step 3 should be: 576pi / 64pi = 64pi h / 64pi

Step 4:  9 = h.

I would say C and D.

Answer:

C. In step 4, the (pie) should have canceled, making the correct answer 9 cm.

Step-by-step explanation:

We know that,

The volume of a cylinder is,

[tex]V=\pi(r)^2h[/tex]

Where r is the radius of the cylinder,

h be the height of the cylinder,

Given,

[tex]V=576\pi \text{ cubic cm}[/tex]

r = 8 cm,

So, for finding the height of the cylinder the steps are as follows,

Step 1 : [tex]576\pi =\pi (8)^2h[/tex]

Step 2 : [tex]576\pi =\pi (64)h[/tex]

Step 3 : [tex]\frac{576\pi}{64\pi} =\frac{\pi (64)}{64\pi}h[/tex]

Step 4 : [tex]h = 9\text{ cm}[/tex]

Thus, it is clear that she had her mistake in 4th step,

She should cancel out [tex]\pi[/tex].

Option C is correct.

Answer:

4 balls

Step-by-step explanation:

108/8=13.5 or 13 R 4

For this case we must divide the number of baseballs among the number of players. Let "x" be the variable that represents the amount of baseballs that each player has to play. So:

[tex]x = \frac {108} {8}\\x = 13.5[/tex]

Rounding down, [tex]x = 13.[/tex]

Each player gets 13 baseballs. Then there are:

[tex]108-13 * 8 = 108-104 = 4[/tex] baseballs

Answer:

4 baseballs

Answer:

C). all numbers greater than zero

Step-by-step explanation:

We have been given a logarithmic function [tex]y=\log_{10}x[/tex].

Now we need to find about what is the domain of the given function then match with the correct choice from the given choices:

A). all numbers greater than or equal to zero

B). all numbers less than zero

C). all numbers greater than zero

By definition of logarithmic function we know that log is not defined for 0 or negative values.

Hence domain of given function must be

C). all numbers greater than zero

The answer is:

The third option,

All numbers greater than zero.

The logarithmic function exists only from the numbers greater than zero to all the positive numbers, we must remember that the logarithmic function is the inverse to the exponential function, which domain is equal to all numbers greater than zero.

Hence, the answer is the third option:

All numbers greater than zero.

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

y=5x-3 what is the point slope form of this equation?

The point-slope form looks like y - k = m(x - h), where (h, k) is the given point and m is the given slope.

Here the given point is (-2, -13).  Therefore, the desired equation is:

y -(-13) = 5( x - [-2] ), or

y + 13 = 5(x + 2)

Answer:

[tex]y+13=5(x+2)[/tex]

Step-by-step explanation:

The given function passes through (-2,-13).

The slope-intercept form of this equation is [tex]y=5x-3[/tex].

This implies that; the slope of the given function is;

[tex]m=5[/tex]

The point-slope form of this function is given by the formula;

[tex]y-y_1=m(x-x_1)[/tex]

We have [tex](x_1,y_1)=(-2,-13)[/tex]

We substitute the point and the slope into the function to obtain;

[tex]y--13=5(x--2)[/tex]

[tex]y+13=5(x+2)[/tex]

For this case, we have that by definition, be given two functions f (x) and g (x). So:

[tex](f-g) (x) = f (x) -g (x)[/tex]

We have:[tex]f (x) = - 3x-5\\g (x) = 4x-2[/tex]

So:

(f-g) (x) = - 3x-5- (4x-2)

We have to:

[tex]- * + = -\\(f-g) (x) = - 3x-5-4x + 2[/tex]

Equal signs are added and the same sign is placed while different signs are subtracted and the sign of the greater is placed

[tex](f-g) (x) = - 7x-3[/tex]

Answer:

Option D

Answer:  No, this is not a representative sample because each type of weed should be represented in proportion to the number of weeds actually present in the yard.

Step-by-step explanation:

A representative sample has to be in proportion, and the diagram shows that the greater part is not represented in proportion. Because it is not represented in proportion, it is not a representative sample.

Answer: C

Answer:

Letter C because the sample size is not in proportion to the rest of the weeds in the grass.

The area of the shaded portion of the circle is option G. 28.5cm²

How did we get the value?

To find the shaded area of a circle, you need to know the radius of the circle and the central angle of the sector that forms the shaded region. The formula for the area of a sector (a portion of a circle) is given by:

[tex]\[ \text{Area of Sector} = \left( \frac{\text{Central Angle}}{360^\circ} \right) \times \pi r^2 \][/tex]

where:

- [tex]\( \text{Central Angle} \)[/tex] is the measure of the angle at the center of the circle (in degrees),

- [tex]\( \pi \)[/tex] is a mathematical constant approximately equal to 3.14159, and

- [tex]\( r \)[/tex] is the radius of the circle.

If the shaded region is not a complete sector but a segment (a portion of the circle bounded by a chord and an arc), you may need to subtract the area of the triangle formed by the radius and the two radii extending to the endpoints of the chord. The formula for the area of the segment is then:

[tex]\[ \text{Area of Segment} = \text{Area of Sector} - \text{Area of Triangle} \][/tex]

One can find the shaded area by:

1. Determine the radius [tex](\( r \))[/tex] of the circle.

2. Find the measure of the central angle [tex](\( \text{Central Angle} \))[/tex] of the sector or segment.

3. Apply the formula to calculate the area of the sector [tex](\( \text{Area of Sector} \))[/tex].

4. If it's a segment, find the area of the triangle formed by the radii and the chord and subtract it from the area of the sector.

[tex]\[ \text{Area of Quarter Circle} = \frac{1}{4} \times \pi r^2 \][/tex]

Given that the radius [tex](\( r \))[/tex] is 10, you can substitute this value into the formula:

[tex]\[ \text{Area of Quarter Circle} = \frac{1}{4} \times \pi \times (10)^2 \][/tex]

Let's calculate this:

[tex]\[ \text{Area of Quarter Circle} = \frac{1}{4} \times \pi \times 100 \][/tex]

[tex]\[ \text{Area of Quarter Circle} = \frac{1}{4} \times 100 \pi \][/tex]

[tex]\[ \text{Area of Quarter Circle} = 25 \pi \][/tex]

1/2 × 10 × 10 = 50cm²

25π - 50 = 25 × 3.14 - 50

              = 78.5 - 50

              = 28.5cm²

Answer:

B

Step-by-step explanation:

Use the formula for radius and circle circumference.

[tex]d=2r \\ \\ C=2\pi r[/tex]

Since we know the diameter, if we divide that by 2, we can get the radius.

[tex]29.5/2=14.75[/tex]

Now we can plug that value into the circumference formula to get the circumference.

[tex]C=2(14.75)\pi \\ \\ C=29.5\pi \\ \\ C=93[/tex]

*Since we're rounding to the nearest inch.

Check the picture below.

make sure your calculator is in Degree mode.

The value of V is 16.

V=16

Explanation

Answer: v=16

Step-by-step explanation:

Given: The inverse variation equation :

[tex]p=\dfrac{8}{v}[/tex]

To find the value of v when p = 1/2, replace the value of p by 1/3 in the above  inverse equation, we get

[tex]\dfrac{1}{2}=\dfrac{8}{v}[/tex]

Multiply 2v on both the sides , we get

[tex]\dfrac{1}{2}\times2v=\dfrac{8}{v}\times2v\\\\\Rightarrow\ v=16[/tex]

Hence, the the value of v =16.
