Find the total amount due on a simple-interest loan if the principal is $3000 with a rate of 5% for 10 years.
Answers
Final answer:
The total amount due on the simple-interest loan is $4500.
Explanation:
To find the total amount due on a simple-interest loan, we can use the formula:
Total Amount = Principal + (Principal x Rate x Time)
Given that the Principal is $3000, the Rate is 5%, and the Time is 10 years, we can substitute these values into the formula to calculate the total amount:
Total Amount = $3000 + ($3000 x 0.05 x 10)Total Amount = $3000 + $1500Total Amount = $4500Therefore, the total amount due on the loan is $4500.

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y - x = -12
Answers
To find the equation of a line parallel to 3y - x = -12 that goes through the point (18, 2), first find the slope of the given line, which is 1/3. Then, use the point-slope form with the given point and the slope to write the equation of the desired line, which is y = (1/3)x - 4.
Explanation:To write an equation of the line that passes through the point (18, 2) and is parallel to the line 3y - x = -12, we first need to find the slope of the given line. For a line to be parallel, it must have the same slope as the line to which it is parallel. We start by putting the equation of the given line in slope-intercept form (y = mx + b).
First, isolate y:
3y = x - 12
y = (1/3)x - 4
The slope (m) of the given line is 1/3. Our parallel line should have the same slope, so we'll use this slope and the point (18, 2) in the point-slope form of a line equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line.
Now, plug in the values:
y - 2 = (1/3)(x - 18)
This is the point-slope form of the equation for our parallel line. To put it into slope-intercept form, we distribute and simplify:
y - 2 = (1/3)x - 6
y = (1/3)x - 4

A car travels down a highway at 45 m/s. An observer stands 200 m from the highway.
How fast is the distance from the observer to the car increasing when the car passes in front of the observer?
How fast is the distance increasing 40 s later?
Answers
so, the left-side is when the car is right in front of the observer, at that point, notice the y-distance, is pancaked, so is 0, but increasing, we know dy/dt is 45 m/s, and notice the "r" distance, is the same as the "x" distance, keeping in mind that whilst "r" is increasing or moving about, "x" is static, is a constant.
[tex]\bf \stackrel{\textit{pythagorean theorem}}{r^2=x^2+y^2}\implies 2r\cfrac{dr}{dt}=\stackrel{constant}{0}+2y\cfrac{dy}{dt} \\\\\\ 2r\cfrac{dr}{dt}=0+2(0)(45)\implies \cfrac{dr}{dt}=0[/tex]
now, 40 seconds later, since the car is going at 45 m/s, in 40 seconds it has covered 40 * 45 meters, or 1800, so y = 1800, x = 200, what is "r"?
[tex]\bf r^2=x^2+y^2\implies r=\sqrt{200^2+1800^2}\implies r=\sqrt{3280000} \\\\\\ r=\sqrt{200^2\cdot 82}\implies r=200\sqrt{82}\\\\ -------------------------------\\\\ 2r\cfrac{dr}{dt}=0+2y\cfrac{dy}{dt}\implies \cfrac{dr}{dt}=\cfrac{y\frac{dy}{dt}}{r}\quad \begin{cases} r=200\sqrt{82}\\ y=1800\\ \frac{dy}{dt}=45 \end{cases} \\\\\\ \cfrac{dr}{dt}=\cfrac{1800\cdot 45}{200\sqrt{82}}\implies \cfrac{dr}{dt}=\cfrac{405}{\sqrt{82}}\implies \cfrac{dr}{dt}=\cfrac{405\sqrt{82}}{82}[/tex]
We can solve for x using a technique called successive approximations. step 1: if we assume that x is very small compared to 0.100 (such that 0.100 x ≈ 0.100) then our first approximation of x (let\'s call it x1) can be calculated as
Answers
Supposed that we are given the equation:
7.20 x 10^-5 = x(0.100+x)^2
So assuming that x is very small so that:
0.100 + x ~ 0.100
and calling it x1, so:
7.20 x 10^-5 = x1 (0.100)^2
Then we simply solve for x1:
x1 = 7.20 x 10^-5 / (0.100)^2
x1 = 7.20 x 10^-3
Final answer:
Successive approximations involve iterative guesses to find a solution, Newton's Method refines initial guesses using derivatives, and the Intermediate Value Theorem guarantees a solution in a given interval.
Explanation:
Successive Approximations: When solving for x using successive approximations, we make iterative guesses, refining our estimation with each step. The method involves making an initial guess, then refining it until a sufficiently accurate solution is obtained.
Newton's Method: Newton's method is a numerical technique used to find roots of a function. It involves making an initial guess and then iteratively improving upon it by using the function's derivative.
Intermediate Value Theorem: The intermediate value theorem states that a continuous function that takes on values of opposite signs at two points must have at least one root within that interval.

What is an a priori proposition? an a posteriori proposition?
Answers
a posteriori means as things are after any event.
Final answer:
An a priori proposition is knowledge known through reason alone, such as mathematical truths, while an a posteriori proposition requires empirical experience, like knowledge of a physical location.
Explanation:
An a priori proposition is a type of knowledge or statement that is known to be true independently of experience. It relies on reason or logical deduction rather than empirical evidence. For example, mathematical truths, such as the statement "The square root of 9 is 3," are considered a priori because they can be known through reason alone. In contrast, an a posteriori proposition is one that requires experience or sensory input to be known. Empirical knowledge, like knowing the best route to a location, is typically a posteriori because it is based on observations from the world around us.
The foundational philosophical debate revolves around the nature of these propositions, with some philosophers questioning whether any knowledge is genuinely a priori or if all understanding comes from some form of experience. However, in many cases, a priori knowledge is associated with necessity, certainty, and independence from experience, while a posteriori knowledge is empirical and grounded in sense perception.

Answers
make sure your calculator is in Degree mode, if you need the angles in degrees, or Radian mode if you need them in radians.
and their difference is clearly just C - A.
Answer
Difference between m∠C and m∠A= 44.76
Step-by-step explanation:
The hypotenuse of right triangle ABC, line segment AC, measures 13 cm. The length of line segment BC is 5 cm.
Hypotenuse AC = 13 cm
So angle B is right angle = 90 degrees
AC is the hypotenuse
BC is the adjacent side for C
cos (c)= adjacent side / hypotenuse
C= cos^-1(BC/AC)
[tex]C= cos^{-1}(\frac{5}{13})= 67.38[/tex]
angle B is a right angle= 90 degree
Angle C= 67.38 degrees
Sum of angles in a triangle is 180°
A + B +C = 180
A + 90 + 67.38 = 180
A= 180 - 90 - 67.38=22.62
Difference between m∠C and m∠A= 67.38 - 22.62=44.76

A box contains marbles of five different colors: red, green, blue, yellow, and purple. there is an equal number of each color. assign probabilities to each color in the sample space. (give your answers as fractions.)
Answers
P(green) = 1/5
P(blue) = 1/5
P(yellow) = 1/5
P(purple) = 1/5
The reason the fractions are all the same is that there are equal numbers of each color. For example, if there were 7 marbles of each color, there would be a total of 35 marbles.
P(red) = 7/35 = 1/5
Similar for the other colors.
To assign probabilities to each color in the sample space of marbles in a box, you need to determine the total number of marbles and the number of marbles of each color. Assuming there is an equal number of each color, the probability of drawing each color is 1/5.
Explanation:To assign probabilities to each color in the sample space, we need to determine the total number of marbles and the number of marbles of each color. Since there is an equal number of each color, let's assume there are n marbles of each color.
The total number of marbles is 5n. The probability of drawing a red marble is n/5n = 1/5. Similarly, the probability of drawing a green marble is n/5n = 1/5, the probability of drawing a blue marble is n/5n = 1/5, the probability of drawing a yellow marble is n/5n = 1/5, and the probability of drawing a purple marble is n/5n = 1/5.

and if it was 12.678 rounded, then it would have been rounded to the nearest thousandths place because ur last number is in the thousandths place
u get it ?
Answer:
The number round to nearest tenths.
Step-by-step explanation:
Given : A number changed to 12.6 after it was rounded.
To find : To what place was the number rounded?
Solution :
The number round when the last digit place value is greater than 5, then before that number rounds by 1 and change the number.
In number 12.6 it was rounded to the nearest tenths.
Which means the hundredths place is greater than 5 either 6,7,8 or 9 and the tenths place is definitely 5.
So, the number can be 12.56, 12.57, 12.58, 12.59
If they all round we get the number 12.6.

help .. Solve the literal equation cy−7=5d+3y for y .
Answers
The literal equation cy - 7 = 5d + 3y can be solved for y by first bringing all the y terms to one side, and then factoring y out and dividing by the remaining coefficient to isolate y. The solution is y = (5d + 7) / (c - 3).
To solve the literal equation cy - 7 = 5d + 3y for y, we need to isolate y on one side of the equation. First, we want to bring all the terms containing y to one side and the rest to the other side. We achieve this by subtracting 3y from both sides of the equation and adding 7 to both sides, leading to cy - 3y = 5d + 7.
Now, we factor y out of the terms on the left side thus: y(c - 3) = 5d + 7. Finally, we divide both sides by (c - 3) to get y by itself: y = (5d + 7) / (c - 3). Therefore, we have isolated y and expressed it in terms of c and d.
