A person places $123 in an investment account earning an annual rate of 2.8%,
compounded continuously. Using the formula V = Pert, where V is the value of the
account in t years, P is the principal initially invested, e is the base of a natural
logarithm, and r is the rate of interest, determine the amount of money, to the
nearest cent, in the account after 2 years.
Answer:
V = 130.08
Step-by-step explanation:
To solve we will use the equation V= [tex]Pe^r^t[/tex]
V= what you are solving for
P= initial number ( 123)
R= rate (2.8%)
-we can convert the rate to a decimal by moving the decimal place 2 spaces to the left.
R= 0.028
T= time (2 years)
The equation should be... [tex]V=123e^(^0^.^0^2^8^*^2^)[/tex]
To solve we can first multiply 0.028 and 2
This is = 0.056
[tex]V=123e^0^.^0^5^6[/tex]
Then using a calculator we get...
V = 130.0845

Solve the system of equations using subtraction. Equation 1: 3x-2y= -2 Equation 2: 3x + y = 10 The solution is (? ,?) HURRY PLEASE!!!!
Answer:
the solution is x = 2 and y = 4 OR (2,4)
Step-by-step explanation:
From the question
Equation 1: 3x-2y= -2
Equation 2: 3x + y = 10
Subtract equation 1 from equation 2, that is
3x + y = 10 - (3x -2y = -2)
You get
3x - 3x + y - (-2y) = 10 - (-2)
0 + y + 2y = 10 + 2
3y = 12
Divide both sides by 3
∴ y = 12/3
y = 4
Substitute the value of y into equation 2 to get x
3x + y = 10
3x + 4 = 10
Then,
3x = 10 - 4
3x = 6
Divide both sides by 3
∴ x = 6/3
x = 2
Hence, the solution is x = 2 and y = 4

Answer:
v = 3√6
u = 6√3
Step-by-step explanation:
v = 3√6 because it is an isosceles triangle
u² = 2(3√6)²
u² = 108
u =√108 = 6√3
find the total surface area of the shape
Answer:
510 ft²
Step-by-step explanation:
in the triangle
base (b) = 5 ft
height of the triangle (h1) = 12 ft
height of the prism = 15 ft
Now
Lateral surface area (LSA)
= perimeter of triangular base * height
= ( 13 + 5 + 12) * 15
= 450 ft²
Total surface area
= LSA + 2 * area of triangular base
= 450 + 2 * 1 / 2 * b * h1
= 450 + 5 * 12
= 450 + 60
= 510 ft²

A traffic light is green for 2 minutes, red for 40 seconds, and yellow for 10 seconds. When a car approaches the light, what is
the probability that it is not red?
here total second=170 second
probability that is not red=
[tex] \frac{12}{284} [/tex]
Step-by-step explanation:
i think that is the portability that is not red
The probability that the light is not red is 13/17
How to determine the probability?The given parameters are:
Green = 2 minutes
Red = 40 seconds
Yellow = 10 seconds
Express green as seconds
Green = 120 seconds
The probability that the light is red is:
P(Red) =Red/Total
This gives
P(Red) = 40/(120 + 40 + 10)
Divide
P(Red) = 4/17
The probability that it is not red is:
P(Not Red) = 1 - P(Red)
This gives
P(Not Red) = 1 - 4/17
Subtract
P(Not Red) = 13/17
Hence, the probability that the light is not red is 13/17

Solve. Suppose that 1,000 students took a math examination wherein the maximum score that they can obtain is 100. Their average score is 70 with a standard of the deviation of 5. How many of the students obtained a score from 70 to 95?
Answer:
prolly like 689
Step-by-step explanation:
As per the given data, approximately 499 of the 1,000 students obtained a score from 70 to 95.
What is z-score?A standardized score is an example of a z-score. A z-score is a measure of how far a data point is from the mean in a distribution.
To solve this problem, we need to calculate the number of students who obtained a score from 70 to 95.
First, we need to calculate the z-scores for these two scores using the formula:
z = (score - mean) / standard deviation
For a score of 70:
z = (70 - 70) / 5 = 0
For a score of 95:
z = (95 - 70) / 5 = 5
Next, we need to find the area under the standard normal distribution curve between these two z-scores using a standard normal distribution table or calculator.
The area between z = 0 and z = 5 is approximately 0.499, or 49.9%.
Finally, we can calculate the number of students who obtained a score from 70 to 95 by multiplying this proportion by the total number of students:
Number of students = proportion x total number of students
Number of students = 0.499 x 1000
Number of students ≈ 499
Therefore, approximately 499 of the 1,000 students obtained a score from 70 to 95.

Taylor bought 48 of marshmallows to the bonfire. Taylor and 10 of her friends made s’mores with them. At the end of the night, there were 9 bags left. How many bags of marshmallows did Taylor and her friends go through? (Write the operation and the answer)
Answer:
The operation used is the Subtraction operation
39 bags of marshmallows
Step-by-step explanation:
The operation we would be using here is the Subtraction operation.
Total number of bags if Marshmallows bought = 48 bags
Number of people present = Taylor + 10 friends = 11 people
Amount of Marshmallows left = 9 bags
Hence, the number of bags of marshmallows that Taylor and her friends went through is calculated as:
48 bags of marshmallows - 9 bags of marshmallows
= 39 bags of marshmallows

An airplane takes off at an angle of 15 degrees with the ground. To the nearest 10 feet, how far has the airplane flown when it has covered a horizontal distance of 1800 feet?
Answer:
1863.5 feets
Step-by-step explanation:
Using Trigonometry :
The distance, d in the attached diagram can be obtained using the trigonometric relation :
Cosθ = adjacent / hypotenus
Cos 15° = 1800 / d
0.9659258 = 1800 / d
0.9659258 * d = 1800
d = 1800 / 0.9659258
d = 1863.4971 feets
The distance covered to the nearest 10 feet = 1863.5 feets
