A company borrowed $25,000 at 3.5% and was charged $2,625 in interest. How long was it before the company repaid the money?
Answer-
The company repaid the money in 3 years.
Solution-
A company borrowed $25,000 at 3.5% and was charged $2,625 in interest.
Considering the interest as simple interest,
[tex]\text{interset}=\dfrac{\text{Principal}\cdot \text{Rate of interest}\cdot \text{Time period}}{100}[/tex]
Here,
Interest = $2625
Principal = $25000
Rate of interest = 3.5% annually
Putting the values,
[tex]\Rightarrow 2625=\dfrac{25000\times 3.5\times t}{100}[/tex]
[tex]\Rightarrow t=\dfrac{2625\times 100}{25000\times 3.5}[/tex]
[tex]\Rightarrow t=3\ years[/tex]
Therefore, the company repaid the money in 3 years.
what is the domian of the function y=In (-x+3/2)
The domain of the function y = ln (-x + 3/2) is all real numbers less than 3/2, represented in interval notation as (-∞, 3/2). This is because the argument of the logarithm must be positive, leading to an inequality that restricts x to be less than 3/2.
Explanation:The domain of a function refers to the complete set of possible values of the independent variable. For the function y = ln (-x + 3/2), we must consider where the argument of the natural logarithm, -x + 3/2, is greater than zero. This is because the natural logarithm function is defined only for positive arguments.
To find the domain, set the argument of the logarithm function greater than zero: -x + 3/2 > 0. Solving this inequality, we find -x > -3/2, hence x < 3/2. This means that the domain of the function is all real numbers less than 3/2, which can be written in interval notation as (-∞, 3/2).
The domain of a function is the set of all possible input values. In the function y = ln(-x + 3/2), the natural logarithm function is defined only for positive numbers, so to find the domain, we need to identify the values of x that make the argument of the logarithm greater than zero.
Solve for the argument inside the logarithm to be greater than zero: -x + 3/2 > 0
Simplify the inequality to find the valid domain: x < 3/2
Therefore, the domain of the function y = ln(-x + 3/2) is x < 3/2.
Suppose that we roll a fair die until a 6 comes up.

the vertex of this parabola is at (3,5). When the y-value is 6, the x-value is -1. What is the coefficient of the squared term in the parabolas equation
The coefficient of the squared term in the parabola's equation, with a vertex at (3,5) and passing through the point (-1,6), is 1/16.
The student is asking about the coefficient of the squared term in the parabola's equation given that the vertex is at (3,5) and another point on the parabola is (-1,6). Since we know the vertex, we can write the vertex form of a parabolic equation as:
y = a(x - h)
^2 + k
Plugging the vertex into the equation, we get:
5 = a(3 - 3)
^2 + 5
This simplifies down to:
5 = a(0) + 5
So, we cannot determine 'a' from the vertex alone. However, we can use the other point to find 'a'. Plugging the coordinates (-1,6) into the vertex form, we get:
6 = a(-1 - 3)^2 + 5
6 = a(-4)^2 + 5
6 = 16a + 5
1 = 16a
a = 1/16
Therefore, the coefficient 'a' is 1/16.

A sum of $5000 is invested at an interest rate of 5% per year. Find the time required for the money to double if the interest is compounded continually. A(t)=Pe^rt
The time required for the principal amount to double is 13 years 10 months and 10 days approx.
What is compound interest?Compound interest simply refers to the fact that an investment, loan, or bank account's interest accrues exponentially over time as opposed to linearly over time. The term "compound" is crucial here.
CI Formula. C.I. = Principal (1 + Rate)^time − Principal.
Given, A sum of $5000 is invested at an interest rate of 5% per year.
hence, principle = 5000
Amount = 10000
rate = 5%
let's assume the time is x
Let's solve for time
A(t)= 10000 = 5000* e⁵ˣ/¹⁰⁰
2 = (e)^x/20
taking logs on both sides
ln 2 = x / 20
x = 20 ln2
time required = 20 ln2 = 20 * 0.69 = 13.86
Therefore, To make the amount double at the interest rate of 5% we need time approx 13 years 10 months, and 10 days.

Geneva rode her bike a total of 2 1/2 miles from her house to school. First she rode 4/5 mile from her house to the park. Then she rode 1/5 mile from the park to her friends house . Finally she rode the rest of the way to her school? How many miles did she ride from her friends house to school
Answer:
She rode [tex]1\frac{1}{2}[/tex] miles from her friends house to school.
Step-by-step explanation:
Geneva rode her bike a total = [tex]2\frac{1}{2}[/tex] miles
She rode from her house to the park = [tex]\frac{4}{5}[/tex] miles
She rode from the park to her friend's house = [tex]\frac{1}{5}[/tex] miles
total distance from her house to her friend's house = [tex]\frac{4}{5}+\frac{1}{5}[/tex] = 1 mile
Finally she rode the rest of the way to her school.
distance between her friend's house to school = [tex]2\frac{1}{2}-1[/tex] = [tex]\frac{3}{2}[/tex] miles

find the sum of all 3 digit whole numbers that arw divisible by 13 ?
The sum of all 3-digit whole numbers that are divisible by 13 is [tex]\( \boxed{37674} \)[/tex].
To find the sum of all 3-digit whole numbers that are divisible by 13, we can use the arithmetic series formula.
1. Identify the first and last 3-digit numbers divisible by 13:
- The smallest 3-digit number divisible by 13 is 104 (since [tex]\( 13 \times 8 = 104 \)[/tex]).
- The largest 3-digit number divisible by 13 is 988 (since [tex]\( 13 \times 76 = 988 \)[/tex]).
2. Calculate the number of terms in the series:
- Use the formula for the number of terms n in an arithmetic sequence:
[tex]\[ n = \frac{\text{last term} - \text{first term}}{\text{common difference}} + 1 \][/tex]
Here, the common difference d = 13:
[tex]\[ n = \frac{988 - 104}{13} + 1 = \frac{884}{13} + 1 = 68 + 1 = 69 \][/tex]
3. Find the sum of the arithmetic series:
- The sum [tex]\( S_n \)[/tex] of the first n terms of an arithmetic series is given by:
[tex]\[ S_n = \frac{n}{2} \times (\text{first term} + \text{last term}) \][/tex]
Substitute the values:
[tex]\[ S_{69} = \frac{69}{2} \times (104 + 988) \][/tex]
Simplify the calculation:
[tex]\[ S_{69} = \frac{69}{2} \times 1092 = 34.5 \times 1092 = 37674 \][/tex]
Thus, the sum of all 3-digit whole numbers that are divisible by 13 is [tex]\( \boxed{37674} \)[/tex].

a right triangle has one angle that measures 23 degress.The adjacent leg measures 27.6 cm and the hypotenuse measures 30 cm.What is the approximate area of the triangle?Round to the nearest tenth.Area of a triangle =1/2bh
Answer:
Area of the triangle will be 162.3 cm²
Step-by-step explanation:
From the figure attached,
In the triangle ABC angle ACB = 23°, side BC = 27.6 cm and hypotenuse AC = 30 cm
Now we have to calculate the area of the given right angle triangle.
Since area of a right angle triangle is represented by
Area = [tex]\frac{1}{2}\times b\times h[/tex]
Where b = adjacent side
h = opposite side
To calculate the opposite side of the triangle we will apply Pythagoras theorem in the ΔABC.
AC² = AB² + BC²
AB² = AC² - BC²
AB² = (30)² - (27.6)²
= 900 - 761.76
= 138.24
AB = √138.24
= 11.76
Area of the triangle = [tex]\frac{1}{2}(AB)(BC)[/tex]
= [tex]\frac{1}{2}(11.76)(27.6)[/tex]
= 162.28 cm² ≈ 162.3 cm²
