The least number of significant digits we can trust in the solution is 2.

The relative approximate error (RAE) of 0.004% gives us an indication of the precision of the solution at the end of an iteration, but it does not directly indicate the number of significant digits that can be trusted in the solution.

In general, the number of significant digits that can be trusted in a solution depends on several factors, such as the accuracy of the initial guess, the choice of method for finding the root, and the behavior of the function being evaluated.

As a rough estimate, it is common to assume that the number of significant digits in the solution is equal to the number of significant digits in the RAE, minus one.

In this case, the RAE is 0.004%, which has three significant digits, so the least number of significant digits we can trust in the solution would be

three - 1 = 2 significant digits

The height of the pyramid is 6 cm and the angle EBD is 36.87 degrees

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

AD = 8cm CD = 5cm CE = 10cm

Given that the apex E is directly over the centre, we have

Height (h^2) = CE^2 - AD^2

So, we have

h^2 = 10^2 - 8^2

This gives

h = 6

Here, we can use the definition of tangent which is represented as

tan(EBD) = h/AD

So, we have

tan(EBD) = 6/8

tan(EBD) = 0.75

Take the arctan of both sides

EBD = 36.87

Minimum sample size to satisfy manufacturer requirements is 2401.

The sample size is defined as the number of observations used for determining the estimations of a given population. The size of the sample has been drawn from the population. The number of entities in a subset of a population is selected for analysis.

Given,

Margin of error m = 0.02

for Confidence interval = 95% , Z - value = 1.96

Sample size n = Z²p(1 – p)/m²

p is the proportion of population (generally taken as 0.5),

m is the margin of error.

n = (1.96)²× 0.5(1 - 0.5)/(0.02)²

n = (1.96)²× 0.5(0.5)/(0.02)²

n = 2401

Answer: A, 4[tex]\sqrt{14}[/tex]

Step-by-step explanation:

18^2-10^2=224

[tex]\sqrt{224}[/tex] =4[tex]\sqrt{14}[/tex]

Answer: 4 √ 14

Step-by-step explanation:

Pythagorean theorem is (a^2 + b^2 = c^2)

Step 1. (10^2) + (x^2) = (18^2) {we divided the 20 by 2 to get one right triangle for the pythagorean theorem.}

Step 2. 100 + x^2 = 324

Step 3. x^2 = 224

Step 4. x ≈ 15 (rounded to the nearest whole number) (x = 14.9666295)

Step 5. Eliminate the wrong choices. B and D are both eliminated, because they are whole numbers, and they don't match the answer we got.

Step 6. Find the square root. 2 √ 106 is ≈ 20.59126, which isn't equal to our 14.966, .

Step 7. With all but one answer remaining, the answer would be 4 √ 14, and we can double-check. (14.9666295 = 14.9666295.)

The depth of the submarine after 9 minutes will be -102 feet.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the expression -210+ 12m represents a submarine that began at a depth of 210 feet below sea level and ascended at a rate of 12 feet per minute.

The depth of the submarine after 9 minutes will be calculated as:-

D =  -210+ 12m

D = -210 + ( 12 x 9 )

D = -210 + 108

D = -102 feet

If a triangle has one side of 7 meters and another side of 12 meters, the other side is approximately 13.928 meters long.

A triangle is a three-sided polygon that has three angles and three sides. The sides of a triangle are connected by its angles, and the sum of the angles of a triangle is always equal to 180 degrees. The length of the sides of a triangle affects the size of its angles, and the size of its angles affects the length of its sides.

Now, in the case of a triangle where one side is 7 meters and another side is 12 meters, the length of the third side can be calculated using the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Mathematically, it can be written as

=> a² + b² = c²,

where a and b are the lengths of the two sides, and c is the length of the hypotenuse.

Using the Pythagorean theorem, we can find the length of the third side of the triangle. Let's call the length of the third side "x". So,

=> x² = 7² + 12² = 49 + 144 = 193.

Taking the square root of both sides, we get

x = √(193) = 13.928.

So, the third side of the triangle is approximately 13.928 meters long.

If you start with 150 bacteria micrograms, the colony would have 1,343.61756 bacteria after 8 days.

We solve this problem using our understanding of the rules of calculating percentages. We have been given the condition that bacteria colonies increase by 73% after every 2 days.

So, starting with 150 bacteria,

after 2 days we'll be having

150+ (73% of 150) bacteria

i.e. 150 + (0.73×150)

=150 + 109.5

=259.5 bacteria

and after 4 days the no. will be,

259.5 + (0.73×259.5)

=259.5 + (189.435)

=448.935 bacteria

similarly after 6 days,

448.935 + (0.73×448.935)

=448.935 + (327.722)

=776.65755 bacteria

and finally after 8 days,

=776.65755 + (0.73×776.65755)
