=2,225.5409284924676
Which B is approximately $2,225.54
Ending balance =$2,225.54
Assuming the amount of $1,000 was invested at an interest rate of 16%, compounded continuously, for a period of five years, what the ending balance will be is: $2,225.54
p represent Principal = $1000
r represent Interest rate= 16% or 0.16
t represent=5 years
Now let determine the ending balance
Ending balance= $1000e^(0.16)(5)
Ending balance=$1000e^(0.8)
Ending balance=$1000 X 2.2255409284924
Ending balance=$2,225.5409284924
Ending balance=$2,225.54 (Approximately)
Inconclusion if the amount of $1,000 was invested at an interest rate of 16%, compounded continuously, for a period of five years, what the ending balance will be is: $2,225.54

Givena general quadratic equation
ax²+bx+c = 0
The general formula for finding x is;
x = -b±√b²-4ac/2a
Where a,b and c are the coefficient of x², x and x° respectively
Given the solution in question to be;
x = 5±2√7/3
The quadratic equation that has thw above general solution will be;
3x²-10x+6 = 0
From the equation, a = 3, b= -10 and c = 6
Substituting this value in the general formula to get x we have;
x = -(-10)±√(-10)²-4(3)(6)/2(3)
x = 10±√100-72/6
x = 10±√28/6
x = 10±√7×4/6
x = 10±2√7/6
Dividing through by 2 gave;
x = 2(5±2√7)/6
x = 5±2√7/3 (which gives the solution in question)

Step-by-step explanation:
Let x be the smaller than 4 ×[tex]10^{-2}[/tex].
To find, the number of times smaller is 2 × [tex]10^{-3}[/tex] than 4 × [tex]10^{-2}[/tex] = ?
∴ x = [tex]\dfrac{4\times 10^{-2}}{2\times 10^{-3}}[/tex]
= 2 × [tex]10^{-2}[/tex] × [tex]10^{3}[/tex]
Using the identity,
[tex]a^{m}=\dfrac{1}{a^{-m}}[/tex]
= 2 × [tex]10^{-2+3}[/tex]
Using the identity,
[tex]a^{m} \timesa^{n}=a^{m+n}[/tex]

RS and ST are 2 sides of a regular 12-sided polygon.
RT is a diagonal of the polygon.
Work out the size of angle STR.
You must show your working.
Answer:
15°
Step-by-step explanation:
The exterior angle at vertex S is 360°/12 = 30°. That angle has a measure that is equal to the sum of the congruent angles at R and T of ΔRST. In other words, ...
∠T = 30°/2 = 15°
The size of angle STR is 15°.
The sides of a regular polygon are congruent.
The size of STR is 15 degrees
The polygon is 12-sided.
This means that:
[tex]\mathbf{n =12}[/tex]
The sum of angles in a regular hexagon is 360.
So, the angle at vertex S is:
[tex]\mathbf{\theta = \frac{360}{n}}[/tex]
This gives
[tex]\mathbf{\theta = \frac{360}{12}}[/tex]
[tex]\mathbf{\theta = 30^o}[/tex]
The external angle of a triangle equals the sum of the opposite internal angles.
This means that:
[tex]\mathbf{\theta = \angle STR + \angle SRT}[/tex]
Where:
[tex]\mathbf{ \angle STR = \angle SRT}[/tex]
So, we have:
[tex]\mathbf{\theta = \angle STR + \angle STR}[/tex]
[tex]\mathbf{\theta = 2\angle STR}[/tex]
Substitute [tex]\mathbf{\theta = 30^o}[/tex]
[tex]\mathbf{30^o = 2\angle STR}[/tex]
Divide both sides by 2
[tex]\mathbf{15^o = \angle STR}[/tex]
Rewrite as:
[tex]\mathbf{\angle STR = 15^o }[/tex]
Hence, the size of STR is 15 degrees

Correct Option is 4 and 5.
Let's assume "x" is the length of the tether ball pole shadow, and "y" is the length of the flagpole shadow.
According to the information given, the proportional relationship can be expressed as:
Tether ball pole height / Tether ball pole shadow length = Flagpole height / Flagpole shadow length
The height of the tether ball pole is 333 meters, and the height of the flagpole is 6.8 meters.
So, we have the following equation:
333 meters / x = 6.8 meters / y
Now, let's solve for "y" in each choice and check which choices satisfy the proportional relationship:
Choice A:
333 / 1.35 = 6.8 / 3.4
246.67 ≈ 2
Choice B:
333 / 1.8 = 6.8 / 4.08
185 ≈ 1.67
Choice C:
333 / 3.75 = 6.8 / 8.35
88.8 ≈ 0.81
Choice D:
333 / 0.6 = 6.8 / 1.36
555 ≈ 5
Choice E:
333 / 2 = 6.8 / 4.8
166.5 ≈ 1.42
The two choices that satisfy the proportional relationship are:

A blue rope is three times as long as the red rope. A green rope is five times as long as the blue rope. If the total length is 508.25 meters, what is the length of the blue rope?
Answer:
The length of the blue rope is 80.25 meters.
Step-by-step explanation:
B = Blue Rope
G = Green Rope
R = Red Rope
B=3R (Blue is 3 x as long as Red)
G=5B (Green is 5 x as long as Blue)
B+G+R = 508.25 (The three ropes together are 508.25 meters)
Since B=3R, I will rewrite the equation above
3R + G + R = 508.25
Now, I will write G in terms of R:
G=5B
B=3R, so 5B = 15R (multiply both sides by 5) which means that G=5B=15R, so G=15R.
Rewrite the equation again in terms of R:
3R + 15R + R = 508.25
19R = 508.25 (combine like terms)
R = 26.75 (divide both sides by 19 to solve for R)
Now, use the value 26.75 (R, which is the length of the red rope) to solve for B (the length of the blue rope):
B=3R
B=3(26.75)
B=80.25 meters
The perimeter of a rectangle must be less than 172 feet. If the length is known to be 53 feet, find the range of possible widths for the rectangle. (Note: The formula for the perimeter of a rectangle is P=2l+2w , where l is the length and w is the width).
Express your answer in interval notation. Use decimal form for numerical values.
Answer:
1 - 32.5
Step-by-step explanation:
If the perimider is less then 172, that the limit is 171. 171 - (53)2 = 65. divide that by the two sides that are the width it equals 32.5
Perimeter is the sum of the length of the sides used to make the given figure. The range of the width of the rectangle is (0,33).
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that the perimeter of a rectangle must be less than 172 feet. Also, given that the length of the rectangle is 53 feet. Therefore, we can write inequality of the width of the rectangle as,
2(Length) + 2(Width) < Perimeter
2(53 feet) + 2(Width) < 172 feet
106 feet + 2(Width) < 172 feet
2(Width) < 172 feet - 106 feet
2(Width) < 66 feet
Width < 66feet / 2
Width < 33 feet
Hence, the range of the width of the rectangle is (0,33).

The width of a rectangular painting is 3in. More than twice the height. A frame that is 2.5 in. Wide goes around the painting
Question:
A width of a rectangular painting is 3 in. More than twice the height. A frame that is 2.5 in. Wide goes around the painting
a. write an expression for the combined area of the painting and frame.
b. use the expression to find the combined area when the height of the painting is 12 in.
c. use the expression to find the combined area when the height of the the painting is 15 in.
Answer:
a) (h + 5)(2h + 8) is the expression for the combined area of the painting and frame
b) The combined area when h = 12 is 544 square inches
c) The combined area when h = 15 is 760 square inches
Solution:
Given that,
A frame that is 2.5 inches wide goes around the painting
The frame will go around all 4 sides of the painting.
That means that the length of each side of the painting will increase by 2.5 inches
Therefore,
The height of painting and frame is:
h = h + 2.5 + 2.5
h = h + 5
(2.5 inches on the top and the bottom)
Also given that,
Width of a rectangular painting is 3 inches more than twice the height
w = 3 + 2h
Now the width of painting and frame is:
w = 3 + 2h + 2.5 + 2.5
(Again, 2.5 inches on the top and the bottom)
w = 2h + 8
Thus the combined area of the painting and frame is:
[tex]Combined\ area = (h+5)(2h+8)[/tex]
B) Substitute h = 12 inches
[tex]Combined\ area = (12+5)(2(12)+8)\\\\Combined\ area = 17 \times (24+8) = 17 \times 32\\\\Combined\ area = 544[/tex]
Thus the combined area when h = 12 is 544 square inches
C) Substitute h = 15 inches
[tex]Combined\ area = (15+5)(2(15)+8)\\\\Combined\ area = 20 \times (30+8) = 20 \times 38\\\\Combined\ area = 760[/tex]
Thus combined area when h = 15 is 760 square inches

You have 8 gallons of lemonade to sell. You use cone-shaped cups that are 9 centimeters in diameter and 12 centimeters tall. Each customer uses one paper cup. How many paper cups will you need if you sell all of the lemonade? (1 gal ≈ 3785 cm3)
You will need 119 cups to sell all of the lemonade.
Step-by-step explanation:
Given,
Diameter of cups = 9 cm
Radius of cup = [tex]\frac{Diameter}{2}=\frac{9}{2}=4.5\ cm[/tex]
Height of cups = 12 cm
We will find volume of cup.
[tex]Volume = \frac{1}{3}\pi r^2h\\[/tex]
Putting all the values
[tex]Volume=\frac{1}{3}(3.14)(4.5)^2(12)\\\\Volume=\frac{1}{3}(3.14)(20.25)(12)\\\\Volume= \frac{763.02}{3}\\\\Volume= 254.34\ cm^3[/tex]
Therefore;
Each cup can hold 254.34 cubed centimeter of lemonade.
Number of gallons = 8
1 gallon = 3785 cm³
8 gallons = 3785*8 = 30280 cm³
Let,
x = Number of cups
Volume of lemonade in one cup * Number of cups = Volume of 8 gallons
254.34x=30280
Dividing both sides by 254.34
[tex]\frac{254.34x}{254.34}=\frac{30280}{254.34}\\x=119.05[/tex]
Rounding off to nearest whole number
x = 119
You will need 119 cups to sell all of the lemonade.

What is the value of x?
Answer: x = 15
Step-by-step explanation: The first thing to note is that what we have here are two similar triangles. First we have triangle ABC and secondly we have triangle EDC. Line BD is a transversal that cuts line AE at point C. Hence we can deduce that angle ACB is equal in measurement to angle ECD (opposite angles). Next we also observe that the other two angles are right angles, that is, 90° in size. Therefore we can conclude that the other two angles (angle ABC and angle EDC) are also of the same measurement.
We can now establish the ratio of the similar sides.
Line AB = Line ED
Line AC = Line EC
AB/ED = AC/EC

Let us assume the points are in the order: AOB.
Since the line passes through all these points the slope of the line segment AO = The slope of the line segment AB.
Slope of a line with two points: [tex]$ \frac{y_2 - y_1}{x_2 - x_1} $[/tex] where [tex]$ (x_1, y_1) $[/tex] and [tex]$ (x_2, y_2) $[/tex] are the points given.
[tex]$ (x_1, y_1) = (0,0) $[/tex]
[tex]$ (x_2, y_2) = (-2, b - 14) $[/tex]
Therefore, the slope of the line segment AO = [tex]$ \frac{b - 14}{-2} $[/tex]
Similarly, for the slope of the line segment OB.
The two points are [tex]$ (x_1, y_1) = (0, 0) $[/tex] and [tex]$ (x_2, y_2) = (14 - b, 72) $[/tex].
The slope is: [tex]$ \frac{72}{14 - b } $[/tex]
Since, the slopes are equal we can equate:
[tex]$ \frac{b - 14}{-2} = \frac{72}{14 - b} $[/tex]
[tex]$ \implies \frac{b - 14}{-2} = \frac{72}{-(b - 14)} $[/tex]
[tex]$ \implies (b - 14)^2 = 72 \times 2 = 144 $[/tex]
[tex]$ \implies (b - 14)^2 = 12^2 $[/tex]
Taking square root on both sides we get:
[tex]$ \implies (b - 14) = \pm 12 $[/tex]
[tex]$ \implies b = 2 \hspace{2mm} or \hspace{2mm} 26 $[/tex]
Therefore, the maximum value of b = 26.
Hence, the answer.
Boyle’s law states that the volume of gas varies inversely with applied pressure. Suppose the pressure on 60 cubic meters of gas is raised from 1 atomsphere to 3 atmospheres. What new volume does the gas occupy?
Answer: 20m³
Step-by-step explanation:
From the statement
V <> 1/p --------------------- 1
V = k/p --------------------- 2
K. = VP ---------------------- 3
V = 60 , p = 1
To find k which is a constant, we put those values in equation 3
K = 60 x 1
= 60.
Now from the second statement
V = k/p where p is 3
Therefore,
V = 60/3
= 20m³
