The length of the major arc is (203/18)π.

What is a length of an arc?

The distance along the curved line that makes up the arc is measured using the arc length formula (a segment of a circle). The arc length is, to put it simply, the distance that passes through the curved line of the circle that forms the arc.

Here, we have

The circle with center K has an arc with a radius of 7 inches and an angle subtended at the center which measures 70 degrees.

The major arc LNM would have its central angle measured as:

Angle ∅ = 360 - 70 (Sum of angles on a point equals 360)

Angle ∅ = 290

The calculation for the length of an arc is given as;

Length of arc = (∅/360) x 2πr

Where ∅ = 290, and r = 7, the length of the major arc becomes;

Length of arc = (290/360) x 2 x π x 7

Length of arc = (29/36) x 14π

Length of arc = (29 x π x 14)/36

Length of arc = 203π/18

Hence, the length of the major arc is (203/18)π.

The systematic succession of phases that a product goes through as it develops from start to finish is known as the agile software development life cycle. Concept, conception, iteration, release, maintenance, and retirement are its six phases.

The project management approach a team decides on will have a small impact on the Agile life cycle. For instance, Scrum teams work in sprints, which are brief timeframes akin to iterations. They also have responsibilities that are precisely defined, like Scrum master. Kanban teams, on the other hand, operate more continuously and don't have set roles. Another illustration is Extreme Programming, where teams frequently work in shorter iterations and give engineering practices more attention.

The rate at which the water level is rising when the water level is 5 cm is; dh/dt = 1.6 cm/s

We are told that;

length of square side; s = 4 cm

height of pyramid; h = 11 cm

volumetric rate; dV/dt = 35 cm³/s

Since the base is square shaped and we know that area of a square = s², then we can say that;

Volume of pyramid = ¹/₃s²h

The pyramid has a height of 11 cm and length of its' square base side is 11 cm.

Now, regardless of the water height, the surface of the water will always be square shaped. This implies that the ratio of the height to the top side of square will always be the same. Thus, we can say that; s = 4/8 h = h/2

Thus, Volume is;

V = ¹/₃ × (h/2)² × h

V = ¹/₃ × h³/4

V = h³/12

dV/dt = (3h²/4) dh/dt

Plugging in the relevant values gives;

The value of x in the similar triangles is 11.4.

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

Similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other.

Therefore,

ΔACB ~ ΔEFD

Hence,

AC / EF = CB / FD = AB / ED

Therefore, let's find x

x = AB

ED = 3.8

BC = 15

FD = 5

x / 3.8 = 15 / 5

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

(i)

substitute x = g(x) into f(x) , that is

f(g(x))

= f(x² + 5)

= 2(x² + 5) - 1

= 2x² + 10 - 1

= 2x² + 9

--------------------------------------

(ii)

substitute x = f(x) into g(x) , that is

g(f(x))

= g(2x - 1)

= (2x - 1)² + 5 ← expand factor using FOIL

= 4x² - 4x + 1 + 5

= 4x² - 4x + 6

The rate of change of f(x) = 2(4)^x is equal to the rate of change of the function in the graph. Therefore, the correct answer option is: A. equal to.

Mathematically, the rate of change is also referred to as slope or gradient and it can be calculated by using this formula;

Rate of change, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change, m = (y₂ - y₁)/(x₂ - x₁)

Next, we would determine the rate of change of the value of y with respect to the value of x for the function in the graph, which represents a line that passes through the points (0, 2) and (1, 6):

Rate of change, m = (6 - 2)/(1 - 0)

Rate of change, m = 4/1

Rate of change, m = 4.

From function 1 [f(x) = 2(4)^x], we can logically deduce that the rate of change is equal to 4.

Step-by-step explanation:

First, we multiply 1.67 x 1021:

1.67 x 1021 = 1705.07.

So, 1705.07 is for one drop of water. We need to find 100 drops of water. To do this, we can set up this equation:

1705.07 x 100 = 170,507

Now, we have to convert this number into scientific notation. How do we do this? The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number:
