Suppose an annuity pays 6% annual interest, compounded semi-annually. You invest in this annuity by contributing $4,500 semiannually for 6 years. What will the annuity be worth after 6 years? Assume that the annuity is compounded with the same frequency as deposits are made unless stated otherwise.
The annuity that should be worth after 6 years is $63,900.
Given that,
The present value is $4,500.The semi-annual time period should be = 6 × 2 = 12.The rate of interest on semi-annual basis should be = 6% ÷ 2 = 3%Now the following formula should be used:
\(Amount = Present\ value \times \frac{(1+ rate)^{(n)} - 1} {rate}\\\\= \$4,500 \times \frac{(1+0.03)^{12} - 1}{0.03}\\\\= \$4,500 \times \frac{0.4257}{0.03}\\\\= \$4,500 \times 14.1920\\\\= \$63,864\\\\= \$63,900\)
Therefore we can conclude that the annuity that should be worth after 6 years is $63,900.

Answer: 63900
Step-by-step explanation: Use the savings annuity formula
PN=d((1+r/k)N k−1)r/k
to calculate the value of P6. The question states that r=0.06, d=$4,500, k=2 compounding periods per year, and N=6 years. Substitute these values into the formula results in
P6=$4,500 ((1+0.06/2)6⋅2−1)/(0.06/2).
Simplifying, we have P6=$4,500 ((1.03)12−1)/(0.03). Therefore P6=$63,864.13. Our final answer is 63900.

For the parabola y = (x+14)^2 -4, The value of the y coordinate of the vertex is?
Answer:
-4
Step-by-step explanation:
y = (x+14)^2 -4
The equation is in vertex form
y = a(x-h)^2 + k where (h,k) is the vertex
The y coordinate of the vertex is k = -4
Answer:
y - coordinate = - 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = (x + 14)² - 4 ← is in vertex form
with vertex = (- 14, - 4 )

The solution to the system of equations is (1.6,-1.6).
What is the system of equations?
Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
Here, we have
Given equations:
y = 1.5x - 4....(1)
y = -x....(2)
Substitute y = -x in the first equation
-x = 1.5x - 4
Collect like terms
-1.5x - x = -4
This gives
-2.5x = -4
Divide both sides by -2.5
x = 1.6
Substitute x = 1.6 in y = -x
y = -1.6

Answer:
Step-by-step explanation:
Life in the mid-1800s was marked by widespread prejudice and discrimination against minority groups, including immigrants and African Americans. The period was also characterized by a series of famines that led to significant suffering and mortality. Nativist movements gained popularity, promoting the interests of those born in the United States over those of immigrants. At the same time, millions of emigrants left their homes in search of better opportunities in America, despite the obstacles they faced upon arrival.

Identify the formula to calculate the number of bit strings of length six or less, not counting the empty string. a. Σ7i = 02i b. Σ6i = 02i c. Σ6i = 02i d. (Σ7i = 02i) - 1
The formula to calculate the number of bit strings of length six or less, not counting the empty string, is (Σ6i=0 2i) - 1.
To explain this formula, let's break it down. The Σ6i=0 represents a summation from i=0 to i=6. The 2i represents the number of possibilities for each bit (either 0 or 1) and the summation allows us to count all possible combinations of bit strings of length 6 or less.
However, we need to subtract 1 from the total because we are not counting the empty string. This formula ensures that we are only counting bit strings with at least one bit set to either 0 or 1.
In simpler terms, the formula tells us to take 2 to the power of each possible bit position (from 0 to 6), add up all those possibilities, and then subtract 1 to account for the empty string. This gives us the total number of possible bit strings of length six or less.

Determine whether the function is a polynomial function. If it is a polynomial function, then state the degree and leading coefficient.
The polynomial function is h(x)=\(\sqrt[3]{64x^{3} +27x^{6} }\). The degree of the polynomial is 6 and the leading coefficient is 27.
Given that,
The polynomial function is h(x)=\(\sqrt[3]{64x^{3} +27x^{6} }\)
We have to analyze the function to see if it is a polynomial function. State the degree and leading coefficient if the function is a polynomial.
The sum of one or more terms, each of which is either a number or a number multiplied by the independent variable and raised to a positive integer exponent, is known as a polynomial function.
The exponent of the variable, or zero if there is no variable, determines a term's degree.
The biggest term degree is the polynomial of the Function.
The Distributive Property is used to join terms having the same Degree.
Usually, terms are presented in order of decreasing Degree.
An nth degree polynomial function of x is often stated as follows:
F(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + aₙ₋₂xⁿ⁻² +... + a₁x + a₀
So,
h(x)=\(\sqrt[3]{64x^{3} +27x^{6} }\)
Therefore, the degree of the polynomial is 6 and the leading coefficient is 27.

jessica has four small boxes that are the same size and one large box. Each of the four small boxes is 4 centimeters wide and 2 centimeters long. The large box has a volume of 96 cubic centimeters. jessica puts the four small boxes into the large box. there’s no space leftover.
What is the height of the one small box?
Answer:
H = 3
Step-by-step explanation:
V of Large box = 4 x (V of Small box)
96/4 = 24
24 = V Small box.
V = L x W x H
24 = 2 x 4 x H
24 = 8 x H
3 = H
Therefore height of small box is 3.
The height of the one small box is 4 cm if Jessica puts the four small boxes into the large box. there’s no space leftover.
What is a cuboid?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape.
Jessica has four small boxes that are the same size and one large box.
The dimensions for the small boxes:
Width w = 4 cm
Length l = 2 cm
Volume of a large box = 96 cubic centimetres
As Jessica puts the four small boxes into the large box. there’s no space leftover, mathematically,
The volume of the large box = 4(Volume of the small boxes)
The volume of the large box = 4(l×w×h)
Where h is the height of the small box.
96 = 4(3×2×h)
24h = 96
h = 4 cm (divide by 48 on both sides)
Thus, the height of the one small box is 4 cm if Jessica puts the four small boxes into the large box. there’s no space leftover.

a helpful rule for converting radians to degrees is
Answer:
Degrees = Radians x 180/π
or
Degrees = 57.2958 x radians
Step-by-step explanation:
1 radian = 180/π degrees
1 radian = 57.2958 degrees
Multiply radians by this factor of 57.2958 to get the equivalent measure in degrees
π radians = 180°
2π radians = 360° which is the number of degrees in a circle
For anything greater than 2π radians you will have to subtract 360°
For example, 7 radians using the formula is 7 x (57.2958 ) ≈ 401.07°
But this still falls in the first quadrant, so relative to the x-axis it is
401.07 - 360 = 41.07°

A quantity with an initial value of 8500 grows exponentially at a rate such that the quantity doubles every 9 years. What is the value of the quantity after 23 years, to the nearest hundredth?
Answer: We can use the formula for exponential growth to find the value of the quantity after 23 years:
Q(t) = 8500 * 2^(t/9)
Where Q(t) is the value of the quantity after t years, and t/9 is the number of doublings that have occurred.
Substituting t = 23 into the formula:
Q(23) = 8500 * 2^(23/9) = 8500 * 2^2.56 = 8500 * 12.90 = 109350
So, after 23 years, the quantity has a value of approximately 109,350, rounded to the nearest hundredth.

Simplify: (9x^3+2x^2-5x+4)-(5x^3-7x+4)
Show all steps used to solve this problem and write your final answer in factored form in the space provided.
To simplify (9x^3+2x^2-5x+4)-(5x^3-7x+4), we can start by combining like terms.
First, we need to distribute the negative sign to the second set of parentheses:
(9x^3+2x^2-5x+4) - 1(5x^3-7x-4)
= 9x^3 + 2x^2 - 5x + 4 - 5x^3 + 7x - 4 (distributing the negative sign)
= (9x^3 - 5x^3) + 2x^2 - 5x + (4 - 4 + 7x) (grouping like terms)
= 4x^3 + 2x^2 + 2x (combining like terms)
Therefore, the simplified expression is 4x^3 + 2x^2 + 2x.
We cannot factor this expression further as there are no common factors between the terms.
1) Remove parentheses.
\(9x^{3}+ 2x^{2} -5x+4-5x^{3} +7x-4\)
2) Collect like terms.
\((9x^{3}-5x^{3})+2x^{2} +(-5x+7x)+(4-4)\)
3) Simplify.
