the number inside the parenthesis includes the interest rate ( annual percentage
looking at the possible functions, if you raise the interest rate to the power of 12, you would need to divide the number of years (t) by 12 as well
so the function could be rewritten as A=1000(1.023^12)^t/12
since the annual percentage rate is 2.3% ( 0.023)
divide 0.023/12*100 = 0.19% per month interest

At 2:00 p.m. two cars start toward each other from towns 240 miles apart. If the rate of one car is 10 mph faster than the other, how fast does each car go if they meet at 5:00 p.m.? If 3x represents the distance that the slower car traveled, then which expression represents the distance the faster car traveled?
Answers
To find the speed of each car, we set up and solve an equation based on the given information. The slower car's speed is 35 mph and the faster car's speed is 45 mph.
Explanation:To solve this problem, we need to set up an equation based on the given information. Let's assume that the slower car's speed is x mph, so the faster car's speed would be (x + 10) mph. Since they meet at 5:00 p.m. and start at 2:00 p.m., they have been traveling for 3 hours.
Using the formula: speed = distance/time, we can write the equation:
x * 3 + (x + 10) * 3 = 240
Simplifying the equation, we get:
3x + 3(x + 10) = 240
6x + 30 = 240
6x = 210
x = 35
So, the slower car's speed is 35 mph and the faster car's speed is (35 + 10) = 45 mph.

tony and sal drove in opposite direction from the same starting point. tony averaged 15 mpg faster then sal. after 5 hours they were 425 miles apart. how fast was each of them driving?
Answers
distance = speed * time
distance = 425 miles
time = 5 hours
Sal's speed = s
Tony's speed = s + 15
Since they drove in opposite directions, the speed between them is the sum of the speeds.
distance = speed * time
425 = (s + s + 15) * 5
85 = 2s + 15
70 = 2s
s = 35
s is Sal's speed and is 35 mph.
Tony's speed is 15 mph faster, so Tony's speed = 35 mph + 15 mph = 50 mph
Answer:
Sal's speed was 35 mph
Tony's speed was 50 mph
You need to buy fertilizer for a circular flower bed with a diameter of 13 feet. If one bag will fertilize 10 square feet, how many bags do you need to buy?
Answers
The area of the flower bed is approximately 132.73 square feet. Each bag of fertilizer covers 10 square feet, so we'd need 13.27 bags. Rounding up, we'll need to buy 14 bags.
Explanation:The question involves the calculation of the area of a circular flower bed and determining the amount of fertilizer needed for that area. The area of a circle can be calculated using the formula πr², where 'r' (radius) is half of the diameter. In this case, the diameter of the flower bed is 13 feet, so the radius is 13/2 = 6.5 feet. We then square the radius (6.5²) which gives us 42.25 and multiply by π (approximately 3.14), resulting in an area of approximately 132.73 square feet. Given that each bag of fertilizer covers 10 square feet, we would need 13.27 bags of fertilizer. Since we cannot buy a fraction of a bag, we would need to buy 14 bags to fully cover the flower bed.

What are the real and imaginary parts of the complex number?
-6-i
Answers
imaginary part=-i
Answer:
Real part: -6
Imaginary part: -1
Step-by-step explanation:
A complex number is a number that has a real part and an imaginary part. These numbers usually are represented in the form a + bi where a and b are real numbers and b is the imaginary part (i is actually the solution to the equation [tex]x^{2} +1=0[/tex] or x²=-1 which has no roots in the real numbers and therefore we call the solution √-1=i)
Now, proceeding to the complex number you wrote, if we write it as a + bi we would have a = -6 b = -1
Therefore the real part is a = -6 and the imaginary part would be -1.

There are 50 cards numbered from 1 to 50. two different cards are chosen at random. what is the probability that one number is twice the other number?
Answers
The probability that one number is twice the other number when two different cards are chosen at random is 1/49.
Explanation:To find the probability that one number is twice the other number when two different cards are chosen at random from a set of 50 cards numbered from 1 to 50, we need to determine the number of favorable outcomes and the total number of possible outcomes.
The favorable outcomes occur when one card is twice the value of the other card. Let's consider the smaller number as 'x'. In that case, the larger number would be '2x'. We can see that 'x' can take any value from 1 to 25, since the larger number '2x' should be less than or equal to 50.
So, the number of favorable outcomes is 25. The total number of possible outcomes is the number of ways to choose 2 cards out of 50, which is given by the combination formula: C(50, 2) = 50! / (2! * (50-2)!), which simplifies to 50 * 49 / 2 = 1225.
Therefore, the probability is given by the ratio of the favorable outcomes to the total number of possible outcomes: 25/1225 = 1/49.

The height of a right circular cone is multiplied by 3, but its radius remains fixed. By what factor will the volume of the cone be multiplied?
Answers
The volume of the cone will be multiplied by a factor of [tex]\(3^1 = 3\).[/tex]
The volume of a right circular cone is given by the formula:
[tex]\[ V = \frac{1}{3} \pi r^2 h \][/tex]
where [tex]\( r \)[/tex] is the radius and [tex]\( h \)[/tex] is the height of the cone.
Given that the height of the cone is multiplied by 3, the new height [tex](\( h' \))[/tex] becomes 3 times the original height [tex](\( h \))[/tex]:
[tex]\[ h' = 3h \][/tex]
Now, let's find the volume of the new cone with the updated height:
[tex]\[ V' = \frac{1}{3} \pi r^2 (3h) \][/tex]
[tex]\[ V' = \pi r^2 (h) \times 3 \][/tex]
So, the volume of the new cone is three times the original volume.
Now, let's dive into the explanation:
When the height of a cone is multiplied by a factor, the volume of the cone is directly proportional to the cube of that factor. This is because the volume formula contains the height term raised to the power of 3. So, if the height is tripled, the volume will be multiplied by[tex]\(3^3 = 27\).[/tex]
Alternatively, we can calculate it directly:
Original Volume: [tex]\(V = \frac{1}{3} \pi r^2 h\)[/tex]
New Volume:[tex]\(V' = \frac{1}{3} \pi r^2 (3h) = \pi r^2 h \times 3\)[/tex]
Therefore, the volume of the cone will be multiplied by a factor of [tex]\(3^1 = 3\).[/tex]

Answer: More than 40 students
Step-by-step explanation:
Let x be the number of students .
Given : Mrs. Williams is deciding between two field trips for her class. The Science Center charges $80 plus $5 per student.
i.e. Total cost : [tex]80+5x[/tex] (1)

If they want us to solve for y, let's start by subtracting 6x to both sides. After doing that, the equation is simplified to: 7y = -6x + 8.
To then get "y" by itself, simply divide "y" by 7 to both sides. Simplifying the equation, the equation is now: y = 8 - 6x / 7, letter B.

What is a reasonable conjecture for Mei to make by recognizing a pattern and using inductive reasoning?
Answers
when a pair of parallel lines are intersected by a third line, the alternate interior angles are congruent
A reasonable conjecture for Mei is the Alternate Interior Angles Theorem, which states if a transversal intersects parallel lines, the alternate interior angles are equal.
Explanation:Based on the scenario, a reasonable conjecture for Mei to make would be, if a transversal intersects parallel lines, then the alternate interior angles are congruent. This statement is known as the Alternate Interior Angles Theorem. In other words, in each of Mei's figures, if the angles she measured are alternate interior angles, they should have the same measurement.
For example, if three pairs of parallel lines are intersected by a third line (called a transversal), a pattern that consistently appears is the equality of the alternate interior angles (angles that are on opposite sides of the transversal and inside the parallel lines). This implies, if the two lines are parallel, then any alternate pair of interior angles are equal.

What is the equation of the line in standard form? (-1,-4) (2,2)
Answers
When you set it up, it should look something like this: (2-(-4))/(2-(-1)) which would simplify to 6/3 which would simplify to 2. This only finds your slope, however. Now that you know your slope, you can start by first setting up you equation in slope intercept form which should be in this format: y=mx+b
Since you already know the slope (m) and the x and y values (you can use either coordinate, I'm just using (2,2)) your equation would look something like this: 2=2(2)+b. After this, you solve for b which happens to be -2, making your slope intercept equation: y=2x-2.
Now you can convert to standard form. In standard form, you have to have the equation in this format: ax+by=c where there cannot be decimals, fractions, and everything needs to already have the greatest common factor taken out. When you do this, you first need to subtract over 2x which makes the equation look like this: -2x+y=-2. However, ax cannot be negative, so you multiply your entire equation by -1. You then get your answer: 2x-y=2
