All real numbers make up the domain of a linear function, hence the domain of  \(f(x)=-5x+20x-7\) is  \((-\infty , \infty )\)  . The range of a linear function is also the set of all real numbers, hence   \(f(x)=-5x+20x-7\) has a range of (-\(\infty\), \(\infty\)).

For the formula, \(y = 4x2 + 24x + 13\)

All real numbers make up the domain of a polynomial function, hence the domain of y=4x2+24x+13 is \((-\infty , \infty )\)

We can use calculus or the square root method to determine the function's range. At x=-3, where y=1, the function's minimal value is found. As a result, the function's range is  \([1, \infty )\).

Using the formula \(f(x)=-5x+20x-7:\)

Using related words together, we obtain \(f(x)=15x-7.\)

Therefore, All real numbers make up the domain of a linear function, hence the domain of  \(f(x)=-5x+20x-7\) is  \((-\infty , \infty )\)  . The range of a linear function is also the set of all real numbers, hence   \(f(x)=-5x+20x-7\) has a range of (-\(\infty\), \(\infty\)).

Answer:

The value of y is 216

(and the value of x is 12)

Step-by-step explanation:

The general formula for a geometric sequence is,

\(a_n = a_1(r)^{n-1}\)

Where n represents the nth term, a_1 is the first term and r is the common ratio,

we see that,

r = 6,

the first term is,

a_1 = (x-6)

the 2nd term is,

a_2 = 3x,

the 3rd term is,

a_3 = y, finding y,

first we find x, using the above given formula we have,

\(a_2 = a_1(6)^{2-1}\\3x = (x-6)(6^1)\\3x = 6x -36\\36 = 6x - 3x\\36 = 3x\\x=36/3\\x=12\)

x = 12,

Now, for y we can use the relation between a_3 and a_2,

\(a_3 = a_1(6)^{3-1}\\y = (x-6)(6)^2\\y = (12-6)(6^2)\\y = 6(6^2)\\y = 6^3\\y = 216\)

y = 216

Answer:

y = -x + 2

Step-by-step explanation:

The area of the circle created by the paint is given by the expression 4πt².

The area of the circle is 100π, which is approximately 314.16 in².

The circle will be at least 300 in² in 5 minutes. Yes.

To find the area of the canvas, we multiply the lengths of its sides:

Area = (3x + 5) × (2x + 1)

Expanding the expression:

Area = 6x² + 3x + 10x + 5

Combining like terms:

Area = 6x² + 13x + 5

The area of the canvas is given by the expression 6x² + 13x + 5.

Now, let's find the area of the circle created by the paint.

The area of a circle is given by the formula A = πr², where r represents the radius.

The radius is given by the spreading of paint, which is r(t) = 2t.

Substituting the value of r(t) into the formula, we have:

A[r(t)] = π(2t)²

Simplifying:

A[r(t)] = π(4t²)

A[r(t)] = 4πt²

Now, let's determine if the area of the circle will be at least 300 in² in 5 minutes.

Substitute t = 5 into the area formula:

A[r(5)] = 4π(5)²

A[r(5)] = 4π(25)

A[r(5)] = 100π

Since 314.16 in² is larger than 300 in², the circle created by the paint will be larger than 300 in² in 5 minutes.

The area of the canvas is 12 square inches and the minimum selling price is (a) $1.30

Here, we have

A rectangular frame that is 3 inches by 4 inches:

This means that

So, we have

Area = Base * Height

So, we have:

Area = 3 * 4

Evaluate

Area = 12

Hence, the area, in square inches, of the canvas is 12 sq inches

Start by calculating the Revenue using

Profit = Revenue - Cost

Where

Profit = 420

Cost = 400 * 0.25 = 100

So, we have

Revenue - 100 = 420

Revenue = 520

For the minimum selling price, we have

Minimum = Revenue/Number of brownies

So, we have

Minimum = 520/400

Evaluate

Minimum = 1.30

Hence, the minimum selling price is $1.30

If the brain volumes (cm³) of 20 brains have a mean of 1085.2 cm³ and a standard deviation of 125.6 cm³. For such data: it is significantly low for a brain because 1386.4 cm³ is less than the upper limit.

Mean = 1085.2 cm³

Standard deviation = 125.6 cm³

Hence,

Lower limit = Mean - 2 x Standard deviation

Lower limit  =1085.2 - 2 x 125.6

Lower limit =1161.2 - 251.2

Lower limit  =910

Upper Limit = Mean + 2 x Standard deviation

Upper Limit = 1161.2 +  2 x 125.6

Upper Limit =1161.2 +251.2

Upper Limit =1412.4

The limit of values is from 910 to 1412.4.

A value below 910 will be is considered low and a value above 1412.4  will be considered high

Therefore 1386.4 cm³ is less than the upper limit. Thus it is significantly low for a brain.

Just have a good day

The dimension of the unknown variable x of the deck is equal to 14 feet in length.

A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°).The opposite sides of a rectangle are equal and parallel.

Given in the question is a diagram showing a plan for deck. From the data given, we can write -

Area of Deck = 511 ft.

The value of x can be found out by subtracting the area of the deck from the  area of rectangle having dimensions of length 29 ft and width (16 + 4) = 20 ft. The remaining area will be equated to the sum of the area of rectangle at top right corner having dimensions of length 9 ft and width 4 ft and the area of triangle at lower right corner.

Firstly, we will find the dimensions of the triangle at the lower right. The height of the triangle will be = (20 - 9) ft = 11 ft. The base of the triangle will be = 29 - ( x + 9) ft = (20 - x) ft. Now -

[Area of Rectangle (29 x 20)] - [Area of Deck] = [Area of Rectangle (9 x 4) + Area of triangle (lower right)].

Mathematically -

580 - 511 = 9 x 4 + 1/2 × (20 - x) × 11 = 69

36 + 5.5(20 - x) = 69

36 + 110 - 5.5x = 69

146 - 69 = 5.5x

5.5x = 77

x = 14 ft

Therefore, the dimension of the unknown variable x of the deck is equal to 14 feet.

Given that;

Function is,

y = 4x + 2

Since, the equation equal to the range value:

4 = 4x + 2

Then, we can solve for "x":

4 - 2 = 4x

2 = 4x

x = 1/2

Now that we have the value of "x", we can find the corresponding value of "y" by substituting it into the given equation:

y = 4x + 2

In _____, the shape and size of the image will remain the same as the preimage.

To fill the blanks:

We know that,

When an object moves in a circular arc around a point, then the transformation is known as rotation.

Each point in the preimage and its corresponding point in the image are at equal distances from a given line and also, the line segment joining two such points is perpendicular to the given line. Such transformations are known as reflection.

In both a rotation and reflection, the shape and size of the image will remain the same as the preimage.
