The number which would be the next in the sequence of number is sixty-four i.e., 64.

In mathematics, a geometric progression is a sequence of non-zero numbers where each term after the first multiplies the previous term by a fixed non-zero number called the common ratio. In other words, a geometric progression has consecutive terms with a common ratio. Example: a , a², a³, ..., where aₙ₊₁/aₙ= a

We have , Jamie noted the following sequence: 4, 8, 16, 32, . .. on a sheet of paper. After careful study of the sequence we have provided, is a geometric sequence and the ratio between consecutive terms in the geometric sequence is : (8/4), (16/8), ....

= 2, 2, .....

We have to locate the next number in sequence. To find the next term in a geometric sequence, simply multiply the last term given by the common ratio of the sequence. So, the next number in the sequence is 32 × 2 = 64. Hence, required number is 64.

A _______ is a graph of each data value plotted as a point.

As we know that;

Data points are represented as dots on a graph with an x- and y-axis in a dot plot, sometimes referred to as a strip plot or dot chart, which is a straightforward type of data visualisation.

These kinds of graphs are employed to visually represent particular data trends or groupings. The distribution of a collection of data is shown by a dot plot, which is comparable to a histogram in that it shows the proportion of data points that fall into each category or value on the axis.

Step-by-step explanation:

Haute cuisine is typically characterized by careful preparation and detail-oriented presentation.

Answer: x^2 - 2x + y^2 - 6y + 10 = 0.

Step-by-step explanation: The power station is located 1 mi west and 3 mi north of the center of town, which means that it is located at the point (1, 3) on the coordinate plane. The power outage affected all homes and businesses within a 5 mi radius of the power station, which means that the furthest points from the station affected by the power outage are located on a circle with a radius of 5 mi.

The equation of a circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

Substituting the values for the center of the circle (h, k) = (1, 3) and the radius r = 5, the equation of the circle consisting of the furthest points from the power station affected by the power outage is:

(x - 1)^2 + (y - 3)^2 = 5^2

This simplifies to:

x^2 - 2x + 1 + y^2 - 6y + 9 = 25

Combining like terms, the equation becomes:

x^2 - 2x + y^2 - 6y + 10 = 0

This can be written in standard form as:

x^2 - 2x + y^2 - 6y + 10 = 0

Therefore, the equation of the circle consisting of the furthest points from the power station affected by the power outage is x^2 - 2x + y^2 - 6y + 10 = 0.

Answer: y = 35/4

Step-by-step explanation:

combine like terms: -

12y = -3y - 35 - 5y

-12y = -8y - 35

Add 8y to both sides

-12y = -8y - 35

Simplify

-4y = -35

Divide both sides by the same factor

-4y = -35

-4y/-4 = -35/-4

Simplify

y = 35/4

The expanded equation of the function f(x) = (3x + 2)⁴ is f(x) = 81x + 216x³ + 216x² + 96x + 16

From the question, we have the following parameters that can be used in our computation:

f(x) = (3x + 2)⁴

Using the pascal triangle at n = 4, we have the coefficients to be

Coefficient = 1     4     6     4     1

So, when the function f(x) = (3x + 2)⁴ is expanded, we have

f(x) = 1 * (3x)⁴ + 4 * (3x)³ * 2 + 6 * (3x)² * 2² + 4 * (3x) * 2³ + 1 * 2⁴

Evaluate

f(x) = 81x + 216x³ + 216x² + 96x + 16

Hence, the solution is f(x) = 81x + 216x³ + 216x² + 96x + 16

If both bouquets have 6 tickseeds, the first bouquet ( roses + tickseeds) has more flowers.

The problem can be solved using ratio.

Bouquet 1 :

Every 2 tickseeds there are 7 roses

Hence, the ratio

Tickseed : rose = 2 : 7    

If there are 6 tickseeds, then

2 : 7 = 6 : rose

rose = (6/2) x 7 = 21

Number of flowers = 6 tickseeds + 21 roses = 27 flowers

Bouquet 2 :

Every 3 tickseeds there are 4 daisies

Hence, the ratio

Tickseed : daisy = 3 : 4

If there are 6 tickseeds, then

3 : 4 = 6 : daisy

daisy = (6/3) x 4 = 8

Number of flowers = 6 tickseeds + 4 daisies = 10 flowers

In the triangle DEF, F is 120 degree and F is 4/3rd of E. A straight angle is just a straight line which is where it gets its name. the sum of a triangles angles 180. It is proved by angular defect and triangles area. The angle sum of a triangle will always be equal to 180°. The angle sum of a quadrilateral is equal to 360°, and a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well.

Angle F = 120 degree

F= 4/3 E

E= 90 degree

Answer:

[tex](x-3)^2+(y+7)^2=\dfrac{361}{13}[/tex]

Step-by-step explanation:

The tangent of a circle is always perpendicular to the radius.

Therefore, the center is on a line that is perpendicular to the tangent.

Rearrange the equation of the tangent to make y the subject:

[tex]\begin{aligned}2x+3y-4&=0\\3y&=-2x+4\\y&=-\dfrac{2}{3}x+\dfrac{4}{3}\end{aligned}[/tex]

Therefore, the slope of the tangent line is -²/₃.

If two lines are perpendicular to each other, their slopes are negative reciprocals.  Therefore, the slope of the perpendicular line is ³/₂.

To write the equation of the line perpendicular to the tangent, substitute the found slope and the center point into the point-slope formula:

[tex]\begin{aligned}y-y_1&=m(x-x_1)\\\implies y-(-7)&=\dfrac{3}{2}(x-3)\\y+7&=\dfrac{3}{2}x-\dfrac{9}{2}\\y&=\dfrac{3}{2}x-\dfrac{23}{2}\end{aligned}[/tex]

The point on the circle is the point of intersection of the tangent line and the perpendicular line.  

To find the point of intersection, substitute the equation for the perpendicular line into the equation for the tangent line:

[tex]\implies \dfrac{3}{2}x-\dfrac{23}{2}=-\dfrac{2}{3}x+\dfrac{4}{3}[/tex]

[tex]\implies \dfrac{13}{6}x=\dfrac{77}{6}[/tex]

[tex]\implies x=\dfrac{77}{13}[/tex]

Substitute the found value of x into one of the linear equations and solve for y:

[tex]\implies y=-\dfrac{2}{3}\left( \dfrac{77}{13} \right)+\dfrac{4}{3}[/tex]

[tex]\implies y=-\dfrac{34}{13}[/tex]

Therefore, the point of intersection and hence the point on the circle is:

[tex]\left( \dfrac{77}{13}, -\dfrac{34}{13}\right)[/tex]

[tex]\boxed{\begin{minipage}{5 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h, k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]

To find r², substitute the given center of the circle (3, -7) and the found point into the equation of the circle:

[tex]\implies \left(\dfrac{77}{13} -3 \right)^2+ \left(-\dfrac{34}{13}+7\right)^2=r^2[/tex]

[tex]\implies \left(\dfrac{38}{13} \right)^2+ \left(\dfrac{57}{13}\right)^2=r^2[/tex]

[tex]\implies \dfrac{1444}{169} + \dfrac{3249}{169}=r^2[/tex]

[tex]\implies \dfrac{4693}{169}=r^2[/tex]

[tex]\implies \dfrac{361}{13}=r^2[/tex]

Therefore, the equation of the circle whose center is P(3, -7) and tangent to 2x+3y-4=0 is:

[tex]\boxed{(x-3)^2+(y+7)^2=\dfrac{361}{13}}[/tex]

The perimeter of the whole diagram in cm is derived as 86.6158 cm using trigonometric ratios.

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

Considering the angle P for right-angled triangle formed by extending the line PQ to the base of the trapezium, so that we have opposite side of 7 cm (22 cm - 15 cm)

so; sinP = 7/25.3

P = sin^(-1)(7/25.3)

P = 16.06

The isosceles triangle PQR have the angle;

Q = 180 - 2(16.06) {sum of interior angles of Isosceles triangle with two equal base angles}

Q = 147.88°

Considering the smaller right-angled triangle formed by the height of the trapezium and one side of the Isosceles triangle, we have its angle;

Q = 180° - 147.88° {sum of angles on a straight line}

Q = 32.12

also;

sin32.12 = 7/hypotenuse (one of the equal sides of the Isosceles triangle)

hypotenuse = 7/sin32.12

hypotenuse = 13.1655

The length TS is equal to the adjacent side of the smaller triangle, so;

cos32.12 = TS/13.1655

TS = 13.1655 × cos32.12
