How much interest is earned on an investment of $12,585 at 3.5% interest over 5 years if the interest is compounded MONTHLY?
Answer:
$2,403.02
Step-by-step explanation:
To calculate the amount of interest earned on an investment of $12,585 at 3.5% interest over 5 years if the interest is compounded monthly, we can use the compound interest formula:
[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Compound Interest Formula}\\\\$ I=P\left(1+\frac{r}{n}\right)^{nt}-P$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ interest earned. \\ \phantom{ww}$\bullet$ $P =$ principal amount. \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form). \\ \phantom{ww}$\bullet$ $n =$ number of times interest is applied per year. \\ \phantom{ww}$\bullet$ $t =$ time (in years). \\ \end{minipage}}[/tex]
Given values:
P = $12,585r = 3.5% = 0.035n = 12 (compounded monthly)t = 5 yearsSubstitute the values into the formula and solve for I:
[tex]I=12585\left(1+\dfrac{0.035}{12}\right)^{12 \cdot 5}-12585[/tex]
[tex]I=12585\left(1.00291666...\right)^{60}-12585[/tex]
[tex]I=12585(1.19094282...)-12585[/tex]
[tex]I=14988.015...-12585[/tex]
[tex]I=2403.01550...[/tex]
[tex]I=\$2403.02[/tex]
Therefore, the interest earned on an investment of $12,585 at 3.5% interest over 5 years if the interest is compounded monthly is $2,403.02 (to the nearest cent).
A man receives 6% commission on all sales excluding the first R10 000. If he made R70 000 in sales, how much commission would he get?
The man would receive a commission of R3,600 on sales totaling R70,000, with a 6% commission rate excluding the first R10,000.
How to Calculate the Commission Received?To calculate the commission, we first need to determine the sales amount on which the commission applies.
In this case, the first R10,000 is excluded from the commission calculation.
Therefore, the commission would be calculated on the remaining amount of R70,000 - R10,000 = R60,000.
To find the commission, we multiply the sales amount by the commission rate of 6%:
Commission = R60,000 * 6% = R3,600.
Therefore, the man would receive R3,600 in commission.

Are the two lines parallel, perpendicular or neither? Y + 1= -5x y= 1/5 x -2
The two lines are neither parallel nor perpendicular.
To determine whether two lines are parallel, perpendicular, or neither, we need to compare their slopes. Let's examine the given lines and analyze their slopes:
Line 1: y + 1 = -5x
We can rewrite Line 1 in slope-intercept form (y = mx + b) by isolating y:
y = -5x - 1
From this equation, we can identify that the slope of Line 1 is -5.
Line 2: y = (1/5)x - 2
Line 2 is already in slope-intercept form, and we can observe that the slope of Line 2 is 1/5.
Compare the slopes: The slopes of Line 1 and Line 2 are -5 and 1/5, respectively. Since the slopes are not equal (they are not the same value), the lines are not parallel.
Determine perpendicularity: To determine if the lines are perpendicular, we need to check if the product of their slopes is -1. Multiplying the slopes of Line 1 and Line 2, we have:
(-5) * (1/5) = -1
Since the product is -1, the lines would be perpendicular. However, in this case, the product of the slopes is -1/5, not -1. Therefore, the lines are not perpendicular either.
Hence, the two lines given by the equations y + 1 = -5x and y = (1/5)x - 2 are neither parallel nor perpendicular.

In the space provided below, state whether or not the condition is deducible (valid). If it is not,
comment on the error in the reasoning.
a) If a student has room 303 as his or her homeroom, the student is a freshman. Joe is a student of the
school and has room 303 as his homeroom. Therefore, Joe is a freshman.
b) If the three angles of a triangle are acute, then the triangle is acute. In triangle ABC, angles A and B
are acute. Therefore, triangle ABC is acute.
c) All school buses stop at railroad crossings. A vehicle stopped at the Santa Fe railroad crossing.
Therefore, that vehicle is a school bus.
d) All cloudy days are depressing. Therefore, since I was depressed on Thursday, Thursday was cloudy.
a) The condition is deducible (valid). Joe having room 303 as his homeroom confirms he is a freshman.
b) The condition is deducible (valid). If angles A and B in triangle ABC are acute, then triangle ABC is acute.
c) The condition is not deducible (invalid). A vehicle stopped at a railroad crossing does not necessarily mean it is a school bus.
d) The condition is not deducible (invalid). Being depressed on Thursday does not imply that Thursday was cloudy.
a) The condition is valid. The reasoning is correct because it follows a valid logical form of "If A, then B." In this case, if a student has room 303 as their homeroom (A), then the student is a freshman (B). Joe is a student with room 303 as his homeroom, so it can be deduced that Joe is a freshman.
b) The condition is valid. The reasoning is correct because it follows a valid logical form of "If A, then B." In this case, if the three angles of a triangle are acute (A), then the triangle is acute (B). Given that angles A and B of triangle ABC are acute, it can be deduced that triangle ABC is acute.
c) The condition is not valid. The error in reasoning is called "affirming the consequent." While it is true that all school buses stop at railroad crossings, it does not necessarily mean that any vehicle stopped at the Santa Fe railroad crossing is a school bus. There could be other vehicles, such as cars or trucks, stopped at the crossing for various reasons.
d) The condition is not valid. The error in reasoning is similar to affirming the consequent. Just because all cloudy days are depressing does not mean that all instances of being depressed imply a cloudy day. There could be various reasons for feeling depressed on Thursday, unrelated to the weather conditions.

The exact values of 3^-2 and 4^-3 are 1/9 and 1/64, respectively.
To find the exact values of 3^-2 and 4^-3, we must first understand the concept of exponents. Exponents are a shorthand way of representing repeated multiplication of the same number.
For example, 2^3 means 2 multiplied by itself three times: 2 × 2 × 2 = 8. Similarly, 3^4 means 3 multiplied by itself four times: 3 × 3 × 3 × 3 = 81.
3^-2 can be written as 1/3^2. Using the concept of exponents, 3^2 means 3 multiplied by itself two times: 3 × 3 = 9. Therefore, 3^-2 can be rewritten as 1/9.
4^-3 can be written as 1/4^3. Using the concept of exponents, 4^3 means 4 multiplied by itself three times: 4 × 4 × 4 = 64. Therefore, 4^-3 can be rewritten as 1/64.

Which list includes three processes that are represented in the rock cycle
diagram and lists them in the correct order, starting with x ?
A. Reaction with chemically active fluids, melting, uplift
B. Melting, uplift, reaction with chemically active fluids
OC. Uplift, melting, reaction with chemically active fluids
D. Uplift, reaction with chemically active fluids, melting
In the rock cycle diagram, these three processes occur in a specific order as D. Uplift, reaction with chemically active fluids, melting
Uplift: Uplift refers to the movement of rocks from deep within the Earth's crust towards the surface. This can occur due to tectonic forces, such as plate collisions or volcanic activity. Uplift exposes rocks to the Earth's surface, where they can undergo further processes.
Reaction with chemically active fluids: Once rocks are uplifted and exposed to the surface, they come into contact with chemically active fluids, such as water or magma. These fluids can infiltrate the rocks, leading to chemical reactions and alteration of their composition. This process is commonly observed in hydrothermal systems or areas of volcanic activity.
Melting: The last step in the sequence is melting. When rocks are subjected to intense heat and pressure, either due to tectonic forces or proximity to a magma source, they can undergo partial or complete melting. This molten rock, called magma, can then solidify and form igneous rocks through processes like cooling and crystallization.
Option D correctly represents the order of these processes in the rock cycle diagram. It starts with uplift, followed by the reaction with chemically active fluids, and concludes with melting. Understanding the sequence of these processes is crucial for comprehending the dynamic nature of Earth's geology and the continuous transformation of rocks throughout geological time. Therefore, Option D is correct.

We want to find the probability that an investigator reports 3, 4, or 5 people are consumers of rice. The probability P(X=k) for a binomial distribution is given by the formula:
P(X=k) = C(n, k) * p^k * q^(n-k)
So we want to find P(X=3) + P(X=4) + P(X=5) :
P(X=3) = C(10, 3) * (0.5)^3 * (0.5)^(10-3)

P(X=4) = C(10, 4) * (0.5)^4 * (0.5)^(10-4)

P(X=5) = C(10, 5) * (0.5)^5 * (0.5)^(10-5)

The expected number of investigators who will report three or less of the people interviewed consumed is :

The axiom in Euclidean geometry states that in space, there are at least four points that do not lie in the same plane.
Why important to have at least four non-coplanar points?Having at least four points that do not lie in the same plane is important in concept of Euclidean geometry because it allows for the construction of a three-dimensional coordinate system.
These non-coplanar points together with the three coordinate axes, form a basis for describing and analyzing spatial relationships and measurements. With a three-dimensional coordinate system, geometric figures and their properties are represented and enables the development of various mathematical principles and theorems in three-dimensional space.

A car travels at a speed of 41 meters/second using 756 joules of energy every second. Suppose we know that the car uses 52,700 joules of energy. Set up a calculation to find the number of meters the car travels with this amount of energy.
Drag each tile to the correct location. The tiles can be used more than once.
Js141756
Answer: the car travels 2,870 meters with 52,700 joules of energy.
Step-by-step explanation:
The given car uses 756 joules of energy every second. So, it would use x amount of energy to travel for t seconds. We know that the car uses 52,700 joules of energy. Let's find the time first.T = E ÷ P = 52,700 ÷ 756 = 70 seconds.
Now, we can calculate the distance covered by the car with this amount of energy.
Distance = Speed × Time = 41 m/s × 70 s = 2,870 meters.
Therefore, the car travels 2,870 meters with 52,700 joules of energy.
Water usage varies greatly in different countries, from as little as 20 liters a day
Answer: 287.1 billion liters
Step-by-step explanation:
Water usage per person: 30 liters/day
World population: 9.57 * 10^9
Total water needed = Water usage per person * World population
Total water needed = 30 liters/day * 9.57 * 10^9
To simplify the calculation, we can express 9.57 * 10^9 in scientific notation:
Total water needed ≈ 30 liters/day * 9.57 * 10^9
To multiply the two values, we multiply the numbers and add the exponents:
Total water needed ≈ (30 * 9.57) * 10^(0 + 9)
Total water needed ≈ 287.1 * 10^9
Now, we can convert the result back to standard notation:
Total water needed ≈ 287,100,000,000 liters
Therefore, if every person in the world used 30 liters of water a day, the total amount of water needed for one day would be approximately 287.1 billion liters.
