The amount of compound interest on #640.00 borrowed for 4years at 3% is #163, 840

The formula for determining compound interest is given as;

Compound interest = P ( 1 + r/n)^nt

Where;

Now, substitute the values

Compound interest = 640( 1 + 3/1)^(4×1)

expand the bracket

Compound interest = 640( 1 + 3)^4

Compound interest = 640(4)^4

find the exponential value

Compound interest = 640(256)

Multiply the value

Compound interest = #163, 840

Hence, the value is  #163, 840

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

Garrick's plant:

Zan's plant:

Garrick's plant is shorter than Zan's plant and the difference in heights is

Actual difference = 100 mm - 10 mm = 90 mm

Measured difference = 88 mm - 8 mm = 80 mm

The percentage errors are calculated using

Percentage errors = Difference/Actual measurement * 100%

So, we have

Garrick's actual error = (10 - 8)/10 *100% = 20%

Zan's actual error = (100 - 88)/10 * 100% = 12%

Hence, Garrick's measurement was 20% off and Zan's was 12% off.

There must be 3 equations, If there are 3 variables.

Lets consider  A,B,C as our equations and x, y, and z as the variables.

We will now follow these following steps:

1) By using C, first write z in terms of x and y. Then, Replace z with its equivalent in B.

2) Then write y in terms of x.

3) In A, replace y with its equivalent and replace z with its equivalent then solve A for x. Now you should know the value of x. You should have written y in terms of x so plug x and you will find y.

Aligned Dim constraint option allows you to create a dimensional constraint that has extension lines perpendicular to an angled surface.

In CAD software, a constraint is a restriction or limitation placed on geometric properties by a designer or engineer: An entity in a design model that keeps its structure when the model is altered is referred to as type 203. In addition to relative length and angle, these properties may also include size, shift, and displacement.

The term "plural form constraints" refers to the delineations of geometrical characteristics between two or more entities or solid modelling bodies; these delimiters are definitive for properties of hypothetical physical position and motion, or displacement in parametric design. However, a CAD programme vendor may use different terminology than another.

CAD software for solid modelling, computer-aided architectural design (including building information modelling), computer-aided engineering, assembly modelling, and other CAD subfields frequently uses constraints.

As of 1995, the human population was expected to double within 50 years. If we calculated r for the human population, we would get 1.39. statement is False.

To determine whether the statement is true or false, we need to calculate the doubling time (DT) based on the given growth rate (r) and see if it aligns with the expected doubling time of 50 years.

The formula to calculate the doubling time (DT) for a population with a constant growth rate (r) is:

DT = ln(2) / r

where ln is the natural logarithm (base e).

If the expected doubling time is 50 years, then:

DT = 50 years.

Now, we can calculate the value of r:

r = ln(2) / DT

Plugging in the values:

r = ln(2) / 50 ≈ 0.01386

Comparing the calculated value of r (approximately 0.01386) with the given value of 1.39, we can see that they are not the same.

Therefore, the statement is False. The calculated value of r (0.01386) does not match the given value of 1.39, and it would not result in the human population doubling within 50 years. In reality, with a growth rate of 1.39, the population would grow at an unsustainable rate, leading to an even faster increase in population over time.

Answer:

It is impossible to prove that AABC = ADEF with the information given. In order for us to prove that these two figures are congruent, we would need to know the measures of all the angles in both figures and the lengths of all the sides. Since we only have the measures of some of the angles and the lengths of two sides, we cannot prove that the figures are congruent.

If x and y are two numerical variables, they will have a negative correlation. As the value of x declines, the value of y tends to do the same.

Statistics uses the terms correlation or dependency to describe any statistical relationship between two random variables or bivariate data, regardless of whether it is causal or not. When two variables are negatively correlated, one drops when the other grows.Therefore, if the value of x decreases, the value of y will decrease as well.A negative correlation between x and y means that when x increases, y decreases, and when x decreases, y also decreases. This is expressed by the formula y = -x.

Mutually exclusive events are events that do not occur at the same time. For example, when you toss a coin, the result is either heads or tails, but you cannot get both results. Such events are also called disjoint events because they do not occur at the same time. If A and B are mutually exclusive events, their probabilities are given by P(A or B) or P(A U B).

According to the question:

Mathematics' field of probability deals with numerical representations of the possibility that an event will take place or that a statement is true. An event's probability is a number between 0 and 1, with 1 generally denoting certainty and 0 generally denoting impossibility.

Here,

If everyone chose at random, you would only have a 1/100 chance of receiving your own seat on a plane with 100 seats. However, in the context of this riddle, each participant does not make a random selection; rather, they only do so if all available seats have been occupied.

This indicates that half of the scenarios will resolve themselves (i.e., someone takes the mystery ticket holder's assigned seat allowing every subsequent passenger to take their assigned seat), while the other half will not resolve themselves and you will be seated in the incorrect location, making the probability of any plane occupancy equal to half.

The last sentence of the proof is Because f+e=c, [tex]a^{2} + b^{2} = c^{2}[/tex]. Hence, option b is the correct answer to this question.

We have that △ABC and △CBD are right-angled triangles.

We have to prove [tex]a^{2} + b^{2} = c^{2}[/tex].

We are given the proof too.

Because △ABC and △CBD both have a right angle, and the same angle B is in both triangles, the triangles must be similar by AA.

Likewise, △ABC and △ACD both have a right angle, and the same angle A is in both triangles, so they also must be similar by AA.

The proportions and are true because they are ratios of corresponding parts of similar triangles. The two proportions can be rewritten as

[tex]a^{2}[/tex] = cf and [tex]b^{2}[/tex] = ce.

Adding [tex]b^{2}[/tex] to both sides of the first equation, [tex]a^{2}[/tex] = cf, which results in the equation [tex]a^{2} + b^{2} = cf +b^{2}[/tex].

Because [tex]b^{2}[/tex] and ce are equal, ce can be substituted into the right side of the equation for [tex]b^{2}[/tex], resulting in the equation [tex]a^{2}+b^{2}[/tex] = cf + ce.

Applying the converse of the distributive property results in the equation  [tex]a^{2}+b^{2}[/tex]= c(f + e).

Now Because f+e=c, [tex]a^{2} + b^{2} = c^{2}[/tex] .

The constant of  proportionality is 5 for the relation between x and y.

What is proportional relationship?

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of the constant.

Given table is

x(days)         5    10   15   20

y(swings)      1      2     3    4

Since y is increasing with increase of days(x).

Thus the relation between y and x is in direct proportional.

Assume the relation be x ∝ y

x = ky, where k is constant proportionality.

Putting x = 5 and y = 1:

5 = k × 1

k = 5

Putting x = 10 and y = 2:

10 = k × 2

k = 5

The Pythagoras Theorem defines the relationship between a triangle's perpendicular, hypotenuse, and base. The right-angled triangle theorem is another name for this. The Pythagoras theorem states that a triangle is said to be right-angled if the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be said in the following way:

If Angle equals 90° then Hypotenuse = Perpendicular∧2+ Base∧2.

The base is the side that the right angle is connected to, the neighboring side of the right angle is connected to the hypotenuse by the perpendicular, and the side that the angle is opposite to is known as the hypotenuse. The legs of the hypotenuse are another name for the base.
