What is a example and a non-example of product of 10

Answer:

1.70507 x 10^5

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:

1.70507 x 10^5 is our answer.

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.

Half life of the radioactive substance is 3.6  days

The half life of the element is calculated from the formula

N(t) = N'(1/2)^(t/t')

N(t) = quantity of the substance remaining

t = time elapsed

t' = half life of the substance

A volt-ampere (SI symbol: VA or V A, abbreviated as VA) is the unit of perceived power in an electrical circuit. The apparent power is equal to the product of the root mean square voltage (in volts) and the root mean square current (in amperes). Volt-amperes are commonly used to analyze alternating current (AC) circuits. In direct current (DC) circuits, this product equals the real power in watts. The volt-ampere is dimensionally identical to the watt: 1 VA = 1 W in SI units).

Given, a simulation is performed to estimate the probability of getting at least one run of 3 heads in a row in 10 flips of a fair coin.

We have to find the probability of getting at least one run of 3 heads in a row.

Required Probability = 1 - P(X = 0) - P(X = 1) - P(X = 2)

P(X = 0) = P(X = 1) = P(X = 2) = (1/2)^10

We are told that;

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
