Find the total amount in the compound interest account. 8000 is compounded semiannually at a rate of 11% for 22 years
The total amount in the compound interest account. 8000 is compounded semiannually at a rate of 11% for 22 years is $92371.97
How to determine the total amount?The given parameters are:
Principal, P = 8000
Rate, r =11%
Time, t = 22 years
Semiannually means that n = 2.
The total amount in the compound interest account. 8000 is compounded semiannually at a rate of 11% for 22 years is then calculated as:
Amount = P + P *(1 + r/n)^nt
So, we have:
Amount = 8000 + 8000 * (1 + 11%/2)^(22 * 2)
Evaluate the expression
Amount = 92371.97
Hence, the total amount in the compound interest account. 8000 is compounded semiannually at a rate of 11% for 22 years is $92371.97

A container built for transatlantic shipping is constructed in the shape of a right rectangular prism. Its dimensions are 2 ft by 2 ft by 12.5 ft. If the container is entirely full and, on average, its contents weigh 0.22 pounds per cubic foot, find the total weight of the contents. Round your answer to the nearest pound if necessary.
Answer:
38.81 pounds
Step-by-step explanation:
Considering the definition of right rectangular prism and its volume, the total weight of the contents is 38.81 pounds.
Right rectangular prism
A right rectangular prism (or cuboid) is a polyhedron whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel rectangles and equal two to two.
Volume of right rectangular prism
To calculate the volume of the rectangular prism, it is necessary to find the product of its dimensions, or of the three edges that converge at a certain vertex.
That is, to calculate the volume of a rectangular prism, multiply its 3 dimensions: length×width×height.
Volume of the container
In this case, you know that:
the dimensions of the container built are 7.5 ft by 11.5 ft by 3 ft.
the container is entirely full and, on average, its contents weigh 0.15 pounds per cubic foot.
So, the volume of the container is calculated as:
7.5 ft× 11.5 ft× 3 ft= 258.75 ft³
Then, the total weight of the contents is calculated as:
258.75 ft³× 0.15 pounds per cubic foot= 38.8125 pounds≅ 38.81 pounds
Finally, the total weight of the contents is 38.81 pounds.

The possible values for angles 1, 2, and 3 given that lines a and b are parallel lines include the following:
m∠1 = 60°.m∠2 = 120°.m∠3 = 60°.What are parallel lines?In Mathematics and Geometry, parallel lines are two (2) lines that are always the same (equal) distance apart and never meet or intersect.
Note: Assuming angle 1 is equal to 60 degrees.
In Mathematics and Geometry, the vertical angles theorem states that two (2) opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other:
m∠1 ≅ m∠3 = 60°.
Based on the linear pair postulate, the measure of angle 2 can be determined as follows;
m∠1 + m∠2 = 180°
60° + m∠2 = 180°
m∠2 = 180° - 60°

Which expression is always equivalent to sin x when 0° < x < 90°?
(1) cos (90°- x)
(3) cos (2x)
(2) cos (45° - x)
(4) cos x
The expression that is always equivalent to sin x when 0° < x < 90° is (1) cos (90° - x). Option 1
To understand why, let's analyze the trigonometric functions involved. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. Since we are considering angles between 0° and 90°, we can guarantee that the side opposite the angle will always be the shortest side of the triangle, and the hypotenuse will be the longest side.
Now let's examine the expression cos (90° - x). The cosine of an angle is defined as the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. In a right triangle, when we subtract an angle x from 90°, we are left with the complementary angle to x. This means that the remaining angle in the triangle is 90° - x.
Since the side adjacent to the angle 90° - x is the same as the side opposite the angle x, and the hypotenuse is the same, the ratio of the adjacent side to the hypotenuse remains the same. Therefore, cos (90° - x) is equivalent to sin x for angles between 0° and 90°.
On the other hand, options (2) cos (45° - x) and (3) cos (2x) do not always yield the same value as sin x for all angles between 0° and 90°. The expression cos x (option 4) is equivalent to sin (90° - x), not sin x.
Option 1 is correct.

4) Ben and his friends are going to play putt-putt. At one location, they can pay $2.00
rentals plus $7.50 per game. At another location, it would cost $8.00 for rentals plus
$6.00 per game. How many games would they have to play in order for either location to
cost the same amount?
!I need the equation!
!and the x= answer!
Answer:
Either location costs the same when they play 4 games
Step-by-step explanation:
The total cost for playing putt-putt consists of fixed rentals and a variable amount per game.
On one location Ben and his friends can pay $2 rentals plus $7.50 per game.
If x is the number of games played, then the total cost at this location is:
C1(x) = 7.50x + 2
At another location, it would cost $8 for rentals plus $6 per game. The second function is:
C2(x) = 6x + 8
It's required to find the number of games x in order for either location to cost the same amount.
It can be done by equating both cost functions:
7.50x + 2= 6x + 8
Subtracting 2 and 6x:
7.50 - 6x = 8 -2
Operating:
1.5x = 6
Dividing by 1.5:
x = 6 / 1.5
x = 4 games
Either location costs the same when they play 4 games

The volume of a rectangular prism is 2 x cubed + 9 x squared minus 8 x minus 36 with height x + 2. Using synthetic division, what is the area of the base?
The base area of the prism is 2x² + 5x - 18
How to determine the area of the base?From the question, the given parameters are
Volume = 2 x cubed + 9 x squared minus 8 x minus 36
Height = x + 2
Rewrite properly as
Volume = 2x³ + 9x² - 8x - 36
Height = x + 2
The base area is calculated as
Base area = Volume/Height

An arrow is shot from 3 ft above the top of a hill with a vertical upward velocity of 108 ft/s. If it strikes the plain below after 9.5 s, how high is the hill?
If the arrow is launched at t0, then write an equation describing velocity as a function of time?
The height of the hill is approximately 25.73 ft. Where v0 is the initial velocity (108 ft/s), g is the acceleration due to gravity \((-32.2 ft/s^2)\),
To find the height of the hill, we can use the formula for the vertical position of an object under constant acceleration:
h = h0 + v0t + 1/2at^2
where h is the final height, h0 is the initial height, v0 is the initial velocity, t is the time, and a is the acceleration due to gravity (-32.2 ft/s^2).
In this case, we are given that the initial height h0 is 3 ft, the initial velocity v0 is 108 ft/s, and the time t is 9.5 s. We want to find the height of the hill, which we can denote as h_hill. The final height is the height of the plain, which we can denote as h_plain and assume is zero.
At the highest point of its trajectory, the arrow will have zero vertical velocity, since it will have stopped rising and just started to fall. So we can set the velocity to zero and solve for the time it takes for that to occur. Using the formula for velocity under constant acceleration:
v = v0 + at
we can solve for t when v = 0, h0 = 3 ft, v0 = 108 ft/s, and a = -32.2 ft/s^2:
0 = 108 - 32.2t
t = 108/32.2 ≈ 3.35 s
Thus, it takes the arrow approximately 3.35 s to reach the top of its trajectory.
Using the formula for the height of an object at a given time, we can find the height of the hill by subtracting the height of the arrow at the top of its trajectory from the initial height:
h_hill = h0 + v0t + 1/2at^2 - h_top
where h_top is the height of the arrow at the top of its trajectory. We can find h_top using the formula for the height of an object at the maximum height of its trajectory:
h_top = h0 + v0^2/2a
Plugging in the given values, we get:
h_top = 3 + (108^2)/(2*(-32.2)) ≈ 196.78 ft
Plugging this into the first equation, we get:
h_hill = 3 + 108(3.35) + 1/2(-32.2)(3.35)^2 - 196.78
h_hill ≈ 25.73 ft
If the arrow is launched at t0, the equation describing velocity as a function of time would be:
v(t) = v0 - gt

Answer: Since 1 and 2 have the same measure, angle CED is also equal to 1 and 2. Therefore, triangle CED and triangle CAB are similar by the Angle-Angle (AA) criterion.
Using the properties of similar triangles, we can set up the following proportion:
$\frac{CE}{CA}=\frac{CD}{CB}$
Substituting the given values:
$\frac{CE}{x+4}=\frac{x}{14}$
Cross-multiplying:
$14CE = x(x+4)$
$14CE=x^2+4x$
We also know that triangle ADE and triangle ABC are similar by the AA criterion. Therefore, we can set up the following proportion:
$\frac{DE}{AB}=\frac{AE}{AC}$
Substituting the given values:
$\frac{DE}{18}=\frac{AE}{x+4}$
Cross-multiplying:
$AE = 18\frac{DE}{x+4}$
Now, we can substitute the value of $AE$ in terms of $DE$ into the first equation:
$14CE=x^2+4x$
$14\frac{DE}{x+4}=x^2+4x$
$14DE=x^2+4x(x+4)$
$14DE=x^2+4x^2+16x$
$18x^2+16x-14DE=0$
We can now use the quadratic formula to solve for $x$:
$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
$x=\frac{-16\pm\sqrt{(16)^2-4(18)(-14DE)}}{2(18)}$
$x=\frac{-16\pm\sqrt{256+1008DE}}{36}$
Since $DC=x$, we can now use this equation to find the value of $DC$ for a given value of $DE$. For example, if $DE=5$, we have:
$DC=\frac{-16\pm\sqrt{256+1008(5)}}{36}$
$DC\approx 2.3$ or $DC\approx -3.1$
Since distance cannot be negative, we choose the positive solution:
$DC\approx 2.3$ units.
To find $DE$, we can substitute the value of $DC$ back into one of the earlier equations:
$\frac{CE}{x+4}=\frac{x}{14}$
$\frac{CE}{2.3+4}=\frac{2.3}{14}$
$CE\approx 1.34$ units
Now we can use the second similarity proportion to find $DE$:
$\frac{DE}{18}=\frac{AE}{x+4}$
$\frac{DE}{18}=\frac{18-1.34}{2.3+4}$
$DE\approx 3.64$ units
Therefore, $DC\approx 2.3$ units and $DE\approx 3.64$ units.
