Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. The Balance after the fifth year from now is 3801.56.
Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,
SI = PRT
where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.
The balance in the accounts can be calculated as,
Balance after the first year,
A = 600×(1.08) = 648
Balance after the second year,
A = (600+648)(1.08) = 1248(1.08) = 1347.84
Balance after the third year,
A = (1347.84+600)(1.08) = 1947.84 (1.08) = 2103.67
Balance after the fourth year,
A = (2103.67+600)(1.08) = 2703.67 (1.08) = 2919.96
Balance after the fifth year,
A = (2919.96+600)(1.08) = 3519.96 (1.08) = 3801.56
Hence, the Balance after the fifth year from now is 3801.56.

0.5cm=1.5m. 36m tall. Find the scale factor.
Final answer:
To find the model height for an object that is 36 m tall using the given scale of 0.5 cm equals 1.5 m, we establish a proportion, which yields a model height of 12 cm, representing the scale factor as 1 cm : 3 m.
Explanation:
The question asks to find the scale factor given that 0.5 cm on a model equals 1.5 m in real life, and an object's real-life height is 36 meters. First, understand that the scale factor is the ratio of the model's size to the actual size. For this scenario, the given scale is 0.5 cm = 1.5 m. To find the model height for an object that is 36 m tall, we use this scale.
Set up a proportion based on the given scale: 0.5 cm/1.5 m = x cm/36 m. Simplifying the ratio to its smallest form, we get 1 cm = 3 m. Therefore, using cross multiplication, we find the height of the model as x = 0.5 cm * (36 m / 1.5 m).
Calculating gives x = 12 cm. Hence, the scale factor, when considering the model's size to the actual size, is represented as 1 cm : 3 m, and the actual model height is 12 cm for the 36 m tall object.

Write the equation of the line passing through (−1, 0) and (0, −3).
The equation of the line passing through (-1, 0) and (0, -3) is y = -3x - 3, where -3 is the slope, and -3 is also the y-intercept.
The equation of a line can be written in slope-intercept form as y = mx + b, where m is the slope of the line, and b is the y-intercept. To find the slope m, we can use the two points given; the slope is the change in y over the change in x, which is (-3 - 0)/(0 - (-1)) = -3/1 = -3. With the slope found, and knowing that the line passes through the point (0, -3), we can say the y-intercept b is -3. The equation of the line through the points (-1, 0) and (0, -3) is y = -3x - 3.

suppose that a pair of 7 sided dice is tossed. What is the expected value of the sum?
The expected value of the sum when rolling a pair of 7-sided dice is 8.
Explanation:When rolling a pair of 7-sided dice, each die has numbers 1 through 7 on its faces. To find the expected value of the sum, we need to calculate the average of all possible sums.
The first die can have 7 possible outcomes, and for each outcome, the second die can also have 7 possible outcomes. This gives us a total of 7*7=49 possible outcomes. The sums of these outcomes range from 2 (1+1) to 14 (7+7).
To find the expected value, we multiply each sum by its probability and sum them up. Since each sum has an equal probability of occurring (1/49), we can simplify the calculation:
Expected value = (2*1/49) + (3*1/49) + (4*1/49) + ... + (14*1/49) = 8
Therefore, the expected value of the sum when rolling a pair of 7-sided dice is 8.

[tex]h(x)=f(g(x))[/tex]
[tex]f(x)=\sqrt{x+2}[/tex]
now, we can replace x as g(x)

[tex](\sqrt{x+5})^2=(\sqrt{g(x)+2})^2[/tex]
[tex]x+5=g(x)+2[/tex]

Dr. Silas studies a culture of bacteria under a microscope. The function b(t)=50(1.4)^t represents the number of bacteria t hours after Dr. Silas begins her study.

b) Is this exponential growth or decay? How do you know?
c) How many bacteria would there be 5 hours after Dr. Silas began her study?
Please show all your work!
The function relates to a bacteria count that starts at 50, grows exponentially due to the base of the exponent being greater than 1, and is projected to reach approximately 192 bacteria after 5 hours.
Explanation:a) The y-intercept of the function is the value of the function when t = 0. For the function [tex]b(t)=50(1.4)^t[/tex], if you substitute 0 for t, you get [tex]50(1.4)^0[/tex] which simplifies to 50. Consequently, the y-intercept is 50 which in context, means the study started with 50 bacteria.
b) This function represents exponential growth. We know this because the base of the exponent (1.4) is greater than 1. If the base had been less than 1, it would represent exponential decay.
c) To determine the number of bacteria 5 hours into the study, we need to substitute 5 for t in the formula.
Hence, [tex]b(5)=50(1.4)^5 = approximately 192.2.[/tex] The number of bacteria cannot be in fractions, thus we consider this as approximately 192.

A trapezoid has an area of 15 square feet. If the bases are 4 feet and 6 feet , what is the height of the trapezoid? Hurry Big test tomorrow this the last one
Final answer:
The height of the trapezoid is 3 feet.
Explanation:
To find the height of a trapezoid with given bases and area, you can use the formula for the area of a trapezoid, which is the average of the two bases multiplied by the height. The formula is as follows:
Area = ½ × (base1 + base2) × height
Given that the area of the trapezoid is 15 square feet and the two bases are 4 feet and 6 feet, the formula becomes:
15 = ½ × (4 + 6) × height
This simplifies to:
15 = ½ × 10 × height
Therefore, we can calculate the height by dividing the area by 5 (which is half of 10):
height = 15 ÷ 5 = 3 feet
So, the height of the trapezoid is 3 feet.

Jerome went on a hike. He climbed three-fourths of a mile in two-thirds of an hour. What was his hiking speed in miles per hour?
Final answer:
Jerome's hiking speed was calculated by dividing the distance he hiked, three-fourths of a mile, by the time it took him, two-thirds of an hour. This yielded a hiking speed of 1.125 miles per hour.
Explanation:
To calculate Jerome's hiking speed in miles per hour, we need to divide the distance he hiked by the time it took him. Jerome hiked three-fourths of a mile in two-thirds of an hour. To find the speed, we use the formula:
Speed = Distance ÷ Time
Speed = ¾ mile ÷ ⅓ hour
To divide fractions, we multiply by the reciprocal of the denominator:
Speed = ¾ × ⅔ = 3/4 × 3/2 = 9/8
This fraction simplifies to 1⅛ (1.125) miles per hour. So, Jerome's hiking speed was 1.125 miles per hour.
It is important to remember that when we talk about speed, we are referring to the distance traveled over a certain period of time regardless of the direction of travel.
