6) How long will it take for an investment to double in value if it earns 4.75% compoundedcontinuously?A) 14.593 yearsB) 15.711 years C) 23.129 years D) 7.296 years
A quantity that is compounded continuously follows the next equation:
[tex]A=Pe^{rt}[/tex]Where:
[tex]\begin{gathered} A=\text{ amount in time ''t''} \\ P=\text{ initial amount} \\ r=\text{ rate of interest in decimal form} \\ t=\text{ time} \end{gathered}[/tex]Now, the interest rate in decimal notation is determined by dividing the percentage by 100:
[tex]r=\frac{4.75}{100}=0.0475[/tex]Now, we are asked to determine the time required for the quantity to double. Therefore, we need to determine "t" when:
[tex]A=2P[/tex]Substituting in the formula we get:
[tex]2P=Pe^{rt}[/tex]Now, we can cancel out the "P":
[tex]2=e^{rt}[/tex]Now, we solve for "t". First, we take the natural logarithm to both sides:
[tex]ln2=lne^{rt}[/tex]Now, we use the following property of logarithms:
[tex]lnx{}^y=ylnx[/tex]Applying the property we get:
[tex]ln2=rtlne[/tex]We have that:
[tex]lne=1[/tex]Therefore:
[tex]ln2=rt[/tex]Now, we divide both sides by "r":
[tex]\frac{ln2}{r}=t[/tex]Now, we substitute the value of "r":
[tex]\frac{ln2}{0.0475}=t[/tex]Solving the operations:
[tex]14.593=t[/tex]Therefore, the right option is A.
Solve the following system for y: 2x+y=43x−12y=−4

86x-24y=-8
subtracting equation,
67y=-164
y=-164/67
As stated in the definition of equation solution, "A solution to an equation is a number that can be plugged in for the variable to make a true number statement," we arrive at the value of y=-164/67 after solving the equations 2x+y=-4 and 43x-12y=-4 for y.

Suppose cone a is similar to cone b and the scale factor between the solids is 3:2, respectively. If the height of cone a is 15 inches, determine the height of cone b.
The height of cone is 10 inches.
What is cone?
A cone is indeed a three-dimensional geometric shape with a smooth transition from a flat base—often but not always circular—to the point at the top, also known as the apex or vertex. A cone is made up of a collection of line segments, half-lines, as well as lines that connect the apex—the common point—to every point on a base that is in a plane other than the apex. The base may only be a circle, any closed one-dimensional figure, any one-dimensional quadratic shape in the plane, or any combination of the above and furthermore all the enclosed points, depending on the author.
What is the formula for finding the height of a cone?
The cone height formula calculates the height of the cone. The height of the cone using cone height formulas are, h = 3V/πr 2 and h = √l2 - r2, where V = Volume of the cone, r = Radius of the cone, and l = Slant height of the cone.We know that
If two figures are similar, then the ratio of its corresponding sides is proportional

Given: The bearing and distance of a ship from Akron(A) through Bellville(B) to Compton(C)
To Determine: The distance travelled and the angles
Solution
The diagram of the journey can be represented as shown below
Let us solve for BC using cosine rule
[tex]\begin{gathered} BC^2=AB^2+AC^2-2(AB)(AC)cosA \\ BC^2=90^2+310^2-2(90)(310)(cos60^0) \\ BC^2=8100+96100-27900 \\ BC^2=76300 \\ BC=\sqrt{76300} \\ BC=276.22km \\ BC\approx276km \end{gathered}[/tex]The total distance travelled is
[tex]\begin{gathered} Total-distance=AB+BC+AC \\ =90km+276km+310km \\ =676km \end{gathered}[/tex]Using sine rule, we can determine the measure of angle C
[tex]\begin{gathered} \frac{AB}{sinC}=\frac{BC}{sinA}=\frac{AC}{sinB} \\ \frac{90}{sinC}=\frac{276}{sin60^0}=\frac{310}{sinB} \\ \frac{90}{sinC}=\frac{276}{sin60^0} \\ sinC=\frac{90(sin60^0)}{276} \\ sinC=\frac{155.88}{276} \\ sinC=0.5648 \\ C=sin^{-1}(0.5648) \\ C=34.39^0 \end{gathered}[/tex]Also know that the sum of angles in a triangle is 180 degree. Therefore
[tex]\begin{gathered} A+B+C=180^0 \\ 60^0+B+34.39^0=180^0 \\ B+94.39^0=180^0 \\ B=180^0-94.39^0 \\ B=85.61^0 \\ B\approx85.6^0 \end{gathered}[/tex]The bearing of Compton from Bellville(B) is
[tex]Bearing(C-from-B)=90^0+34.39^0=124.39^0\approx124.4^0[/tex]The bearring of Akron(A) from Compton(C) is
[tex]Bearing(A-from-C)=270^0+34.39^0=304.39^0\approx304.4^0[/tex]In summary

The model is a linear function that shows $3.25 money that Ilya has all together
What is meant by a linear function?The phrase linear function relates to two distinct but related concepts in mathematics:
Some authors use the term "linear function" only for linear mappings that accept values in the scalar field; these are more frequently known as linear forms.
Calculus' "linear functions" qualify as "linear mappings" when (and only when) f(0,..., 0) = 0, or, equivalently, when the aforementioned constant b equals zero.
A linear function in calculus and related fields is one whose graph is a straight line, that is, a polynomial function of degree zero or one. The word affine function is commonly used to distinguish such a linear function from the other idea.
A linear function is also known as a linear map in linear algebra, mathematical analysis, and functional analysis.

2) The table that represents y as a function of x is; Table 3
How to Interpret Ordered Pairs?An ordered pair is defined as a composition of the x coordinate called the abscissa and the y coordinate called the ordinate having two values written in a fixed order within parentheses.
1) The first function given as {(−1, 0), (−1, 1), (−2, 2), (0, 3)} ; This cannot be regarded as a function because the input x = - 1 is repeated with different output values.
The second function {(−1, 1), (−2, 0), (−3, 4), (−3, 3)} ; This cannot be regraded as a function because the input x = -3 is repeated with different output values.
The third function {(0, 0), (1, 1), (2, 2), (3, 3)}; This is a function because each input has unique output values.
The fourth function {(0, 0), (1, 0), (2, 4), (2, 3)} ; This cannot be regraded as a function because the input x = 2 is repeated with different output values.
2) Table 1 cannot be regarded as a function because the input x = 0 is repeated with different output values.
Table 2 cannot be regarded as a function because the input x = 3 is repeated with different output values.
Table 3 is a Function because each input has unique output values.
Table 4 cannot be regarded as a function because the input x = -1 is repeated with different output values.

Determine the probability of being dealt 4 Aces of cards, from a deck of 52 playing cards, with a replacement.
Before finding the probability of being dealt 4 Aces of cards, let's find the probability of being dealt an Ace card on each draw.
The probability of getting an specific card from a deck is given by the ratio between the amount of this specific card and the total amount of cards. We have 4 Aces in a deck, and 52 cards, therefore, the probability of getting an Ace is
[tex]\frac{4}{52}=\frac{1}{13}[/tex]Since the cards are replaced, it is the same probability of getting an Ace on each draw.
Each draw is an independent event, the probability of them happening simultaneously is given by their product. The probability of being dealt 4 Aces of cards with a replacement is
[tex]\frac{1}{13}\times\frac{1}{13}\times\frac{1}{13}\times\frac{1}{13}=\frac{1}{13^4}=\frac{1}{28561}=0.00003501277\ldots[/tex]Which figures can have two sides of the same length, but are not parallelograms?quadrilateralrectanglesquareisosceles trapezoid
A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
We have special types of quadrilaterals which are,
1) Rectangle
2) Square
3) Rhombus
4) Parallelogram
5) Trapezium
6) Kite
Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms.
An isosceles trapezoid has left and right sides of equal length that join to the base at equal angles.
