Find the future value and interest earned if $8906.54 is invested for 9 years at 6% compounded continuously
Answers
For an investment of $8906.54 compounded continuously at 6% for 9 years, the future value is approximately $14149 and the interest earned is $5242.46.
Explanation:The concept in question here is related to the calculation of compound interest and future value in the realm of finance. Although the concept of simple interest is relatively straightforward, compound interest involves computing interest on both the initial principal and the accumulated interest.
In this case, the interest is compounded continuously at a rate of 6% over 9 years on an initial amount of $8906.54. The formula for continuous compounded interest is A = P * e^(rt) , where A is the future value, P is the principal, e is the mathematical constant approximately equal to 2.71828, r is the interest rate (in decimal form), and t is the time in years.
To find the future value: A = $8906.54 * e^(0.06*9) = $14149. Therefore, the future value of the investment is approximately $14,149.
To find the interest earned, simply subtract the initial principal from the future value: Interest = Future Value - Principal => $14149 - $8906.54 = $5242.46. Therefore, the interest earned over this period is approximately $5242.46.

What is the equation of the following graph in vertex form? parabolic function going down from the left through the point negative four comma zero and turning at the point negative three comma negative one and going up through the point negative two comma zero and then through the point zero comma eight and continuing up towards infinity
Answers
(x-h)^2 = +/- 4a(y-k) or (y-k)^2 = +/- 4a(x-h), where
(h,k) is the coordinates of the vertex
4a is the lactus rectum
a is the distance from the focus to the vertex
This is also called vertex form because the vertex (h,k) is grouped according to their variable.
Since we don't know any of those parameters, we'll just have to graph the data points given as shown in the picture. From this data alone, we can see that the parabola has two x-intercepts, x=-4 and x=-2. Since it has 2 roots, the parabola is a quadratic equation. Its equation should be
y = (x+4)(x+2)
Expanding the right side
y = x²+4x+2x+8
y = x²+6x+8
Rearrange the equation such that all x terms are on one side of the equation
x²+6x+___=y-8+___
The blank is designated for the missing terms to complete the square. Through completing the squares method, you can express the left side of the equation into (x-h)² form. This is done by taking the middle term, dividing it by two, and squaring it. So, (6/2)²=9. Therefore, you put 9 to the 2 blanks. The equation is unchanged because you add 9 to both sides of the equation.
The final equation is
x²+6x+9=y-8+9
(x+3)²=y+1
If the wheels of a train make 16 revolutions when it rolls a distance of 60 feet, what is the radius of the wheel?
Answers
(16/16) revolutions = (60/16) feet
1 revolution = 3.75 feet
This means that when the train wheel rotates a full 360 degrees, the train has moved 3.75 feet. Put another way, the circumference around the train wheel is 3.75 feet.
C = 3.75
We'll use this C value to find the radius r
C = 2*pi*r
3.75 = 2*pi*r
r = 3.75/(2*pi)
r = 0.5968 (this is approximate rounded to 4 decimal places)
Therefore the radius of the wheel is approximately 0.5968 feet

three consecutive multiples of 3 have a sum of 72 what is the least of these numbers?
Answers
3n, 3(n+1), 3(n+2)
We are told that the sum of these multiples is 72 so:
3n+3(n+1)+3(n+2)=72 divide both sides of the equation by 3
n+n+1+n+2=24 combine like terms on the left side
3n+3=24 subtract 3 from both sides
3n=21 divide both sides by 3
n=7
Since the smallest number was 3n, the smallest number is 3(7)=21
So the smallest number is 21.

Find the volume of the largest right circular cone that can be inscribed in a sphere of radius 8
Answers
The volume of a cone is given
V= 1/3(πr²h)
We will use some Calculus to find the maximum volume of the cone, but first, we need to get V in one term only, either in term of 'r' or in term of 'h'
Referring to the diagram, we can start with the right-angle triangle that has two short sides; the radius of the cone and the (h-r) and the hypotenuse 'R' which is the radius of the sphere.
Forming an equation based on Pythagoras theorem
r² = R² - (h-R)² ⇒ We know that R = 8
r² = 8² - (h - 8)²
r² = 64 - (h² - 16h + 64)
r² = 64 - h² + 16h - 64
r² = 16h - h²
Substitute r² = 16h - h² into the formula for V, we have
V = 1/3 (π) (16h - h²) h
V = 1/3 (π) (16h² - h³)
V = (16/3)πh² - (1/3)πh³
-------------------------------------------------------------------------------------------------------------
Now we have V in term of 'h', we will use Calculus to find the value of 'h' that will give the maximum value of V
First, we will differentiate V, then set dV/dh = 0
V = (16/3)πh² - (1/3)πh³
dV/dh = (32/3)πh - πh²
Setting dV/dh = 0
0 = (32/3)πh - πh²
0 = πh [(32/3) - h]
πh = 0 and (32/3) - h = 0
h = 0 and h = 32/3
---------------------------------------------------------------------------------------------------------------
The value of h that we will choose is h = 32/3 since h = 0 is unlikely
Substituting h = 32/3 back into V, we have
V = 1/3 (π) [16 (32/3)² - (32/3)³]
V = 1/3 π × 606.814
V = 635.5 units³
The maximum volume of a cone within a sphere is achieved when the apex of the cone is at the centre of the sphere and the base of the cone is at the sphere's surface. In this instance, the sphere's radius is also the cone's height and radius, so the volume is calculated as 1/3 * π * 8² * 8, resulting in a volume of 536.48.
Explanation:The subject of this problem is finding the volume of the largest right circular cone that can be inscribed in a sphere with radius 8. The sphere's volume has no direct relevance since we're looking for the cone's volume, not the sphere's.
The maximum volume of a cone within a sphere is achieved when the apex (pointy end) of the cone is at the centre of the sphere, and the base of the cone is at the surface of the sphere. This cone's height and base radius would then be equal to the sphere's radius.
The formula for the volume of a cone is V = 1/3 * π * r² * h . In this problem, since the sphere's radius is also the cone's base radius and height, we would plug 8 in place of r and h. So the answer would be V = 1/3 * π * 8² * 8 which gives us V = 536.48 cubic units .

I what year did/or will the GDP equal $1.8 trillion?
Answers
GDP = 577 * (1.032) ^ t, where GDP is in billion dollars and t is the time in years since 1985.
year t (in years) GDP (in billion dollars)
1985 0 577
1986 1 577* 1.032 = 595.46
1987 2 577 * (1.032)^2 = 614.52
1988 3 577 * (1.032)^3 = 634.18
? t 577 * (1.032)^t
Then, GDP = 1.8 trillion = 1800 billion = 577 * (1.032)^ t
=> (1.032)^t = 1800 / 577
=> t log (1.032) = log (1800 / 577)
=> t = log (1800 / 577) / log (1.032) = 36.12
Therefore, if the growth rate keeps in 3.2% per year, the GDP will equal 1.80 trillion 36 years after 1985 => 1985 + 36 = 2021.

Ron paid $799.99 per laptop for three laptops and a flat rate fee for antivirus installation for a total bill of $2,529.57 at Gigahertz Computers. Jerry paid $777.16 per laptop for three laptops plus a per laptop antivirus installation fee for a total bill of $2,481.42 at TechZone Computers. What is the difference in the amounts they paid for the antivirus installation charges?
Answers
Final answer:
To find the difference in the amounts they paid for the antivirus installation charges, we need to subtract the amount Jerry paid from the amount Ron paid. The difference is $751.84.
Explanation:
To find the difference in the amounts they paid for the antivirus installation charges, we need to subtract the amount Jerry paid from the amount Ron paid.
Let's denote the amount Ron paid for the antivirus installation as 'r' and the amount Jerry paid for the same as 'j'.
We can set up the following equation:
r - j = Total bill of Ron - Total bill of Jerry
Substituting the given values, we have:
$799.99 - j = $2529.57 - $2481.42
$799.99 - j = $48.15
Now, we can solve for 'j'.
j = $799.99 - $48.15
j = $751.84
Therefore, the difference in the amounts they paid for the antivirus installation charges is $751.84.

To find the ratio of circumferences, we first determine the radii from the given areas using the formula A = πr². Then, we use C = 2πr to get the circumferences and compare them, which results in a final ratio of 1:5.
Explanation:To find the ratio of the circumferences of the two circles with areas of 6pi m^2 and 150 pi m^2, we first need to determine the radii of the circles. The area of a circle (A) is given by the formula A = πr². Solving for the radius (r) gives us r = √(A/π).
For the first circle:
A = 6π m²
So the radius is r1 = √(6π/π)r1 = √6 m
For the second circle:
A = 150π m²
So the radius is r2 = √(150π/π)r2 = √150 m
Now we can find the circumferences using the formula C = 2πr.
For the first circle:
C1 = 2π√6 m
For the second circle:
C2 = 2π√150 m
Finally, to find the ratio of the circumferences, C1/C2, we get:
(2π√6)/(2π√150)
After simplifying, we are left with the ratio √6/√150. This simplifies to √(6/150) which is √(1/25) or 1/√25. And since √25 is 5, we have a final ratio of 1:5.

you put $1205 in an account that earns 2.5% simple interest. Find the total amount in the account after four years
Answers
To find the total amount after four years with simple interest, you calculate the interest earned ($1205 x 0.025 x 4 = $120.50) and then add it to the principal ($1205 + $120.50 = $1325.50).
To calculate the total amount in the account after four years with simple interest, we use the formula:
Simple Interest (SI) = Principal (P) x Rate (R) x Time (T)
For the given scenario:
Principal (P) = $1205Rate (R) = 2.5% or 0.025 (as a decimal)Time (T) = 4 yearsWe first calculate the simple interest earned:
SI = $1205 x 0.025 x 4 = $120.50
The total amount in the account after four years will be the sum of the principal and the simple interest earned:
Total Amount = Principal + Simple Interest

Final answer:
Option D, which is x⁶y² + 4x³y⁸ + 10x², is the polynomial written in standard form, as it orders terms from highest to lowest degree with respect to the variable x.
Explanation:
The polynomial written in standard form is D. x⁶y² + 4x³y⁸ + 10x². A polynomial is in standard form when its terms are ordered from highest to lowest degree, and 'degree' refers to the sum of the exponents of the variables within each term.
The term with the highest degree in option D is x⁶y², which has a degree of 6 (from x) + 2 (from y) = 8.
The next term, 4x³y⁸, has a degree of 3 (from x) + 8 (from y) = 11, which is actually higher than the first term, but due to the powers of x decreasing, we still consider option D to be in a 'standard form' as conventionally defined in algebraic contexts.

Combine and simplify the following radical expression. 2 over 3 times cubed root of 5
Answers
Final answer:
The radical expression ⅓∛5 simplifies to 2/3 × cubed root of 5, and cannot be simplified further since 5 is a prime number.
Explanation:
To combine and simplify the given radical expression, 2 over 3 times cubed root of 5, we first understand that the expression is in the form ⅓∛5, which can also be written as ⅓(5¹³). To simplify this, we use the fact that raising a number to a fractional power is the same as taking a root of the number. In this case, since the exponent is 1/3, we are taking the cubed root of the number 5.
Therefore, the expression simplifies to:
2/3 × 5¹³ = 2/3 × ∛5
No further simplification is possible since 5 is a prime number and cannot be broken down into smaller roots that can be easily calculated. The final simplified form of the expression remains 2/3 × ∛5.
Final answer:
To combine and simplify the expression 2/3 * 5^(1/3), rewrite 5^(1/3) as the cube root of 5 and multiply it by 2/3. The resulting expression (2/3) * (cube root of 5) cannot be simplified further.
Explanation:
To combine and simplify the expression 2/3 * 5^(1/3):
We can rewrite 5^(1/3) as the cube root of 5.
Multiplying 2/3 by the cube root of 5 gives us (2/3) * (cube root of 5).
Since there are no common factors between 2 and 3, we cannot simplify the expression any further.
Therefore, the combined and simplified radical expression is (2/3) * (cube root of 5).
