Answer:
Maximum height of the rocket = 1194.39 feet.
Step-by-step explanation:
The equation that shows the height of the rocket, y in feet, is related to the time after launch, x in seconds is as follows :
\(y=-16x^2+261x+130\) ...(1)
We need to find the maximum height reached by rocket. For maximum height,
\(\dfrac{dy}{dx}=0\\\\\dfrac{d(-16x^2+261x+130)}{dx}=0\\\\-32x+261=0\\\\x=\dfrac{261}{32}\\\\x=8.15\ s\)
Put x = 8.15 s in equation (1).
\(y=-16(8.15)^2+261(8.15)+130\\\\y=1194.39\ \text{feet}\)
So, the maximum height of the rocket is 1194.39 feet.

Professor Zsolt Ugray lives in Boston and is planning his retirement. He plans to move to Florida and wants to buy a boat. The boat he is buying is a "2007 Sea Ray 340 Sundancer" (see image).
Using your Excel skills and understanding of financial functions, you're helping Prof. Ugray assess the impact of this loan on his finances. To buy this boat, Prof. Ugray will get a large Loan ($150,000) and pay $1,770 monthly during 10 years.
Calculate below:
- The monthly rate for this loan
- The annual rate for this loan
- The effective annual rate for this loan
- Total Amount Paid After 10 Years
- The Future value for this loan.
The monthly rate for the given loan is 1.0118%.The annual rate for this loan is 12.1423%.
Given loan: $150,000
Payment per month: $1,770
Duration of loan: 10 years
Interest = ?
The formula for monthly payment is given by:
\(PV = pmt x (1 - (1 + r)^-n) / r\)
Where, PV is the present value, pmt is the payment per period, r is the interest rate per period and n is the total number of periods.Solving the above formula for r will give us the monthly rate for the loan.
r = 1.0118%The monthly rate for the given loan is 1.0118%.The annual rate can be calculated using the following formula:
Annual rate = \((1 + Monthly rate)^12 - 1\)
Annual rate = 12.1423%
The annual rate for this loan is 12.1423%.The effective annual rate can be calculated using the following formula:
Effective annual rate =\((1 + r/n)^n - 1\)
Where, r is the annual interest rate and n is the number of times interest is compounded per year.If interest is compounded monthly, then n = 12
Effective annual rate = (1 + 1.0118%/12)^12 - 1
Effective annual rate = 12.6801%
The effective annual rate for this loan is 12.6801%.
Total amount paid after 10 years = Monthly payment x Number of payments
Total amount paid after 10 years = $1,770 x 120
Total amount paid after 10 years = $212,400
The total amount paid after 10 years is $212,400.
The future value for this loan can be calculated using the following formula:
FV = PV x (1 + r)^n
Where, PV is the present value, r is the interest rate per period and n is the total number of periods.If the loan is paid off in 10 years, then n = 120 (12 payments per year x 10 years)
FV = $150,000 x (1 + 1.0118%)^120
FV = $259,554.50
The future value for this loan is $259,554.50.
Thus, the monthly rate for the loan is 1.0118%, the annual rate for this loan is 12.1423%, the effective annual rate for this loan is 12.6801%, the total amount paid after 10 years is $212,400 and the future value for this loan is $259,554.50.

1.1. Which statement explains why the two systems of equations below have the
same solution?
A
6x + 8y = -10
2x - 5y = 12
B
8x + 3y = 2
12x + 16y = -20
Answer:
B. The first equation in B is the sum of the equations in A, while the other is obtained
by multiplying the first equation in A by 2.
Step-by-step explanation:
If we add the first two equations that shown in A so
6x + 8y + 2x - 5y = -10 + 12
8x + 3y = 2
Now the first equation in A would be multiplied by 2
So
2(6x + 8y = -10)
12x + 16u = -20
Therefore the correct option is B.
how many such strings are if 2 of the ones are to be next to each other and the third is not next to the other two?
The number of strings where exactly two of the ones are next to each other, while the third one is not next to the other two, is (n-1) x (n-2).
In combinatorics, one of the fundamental concepts is counting the number of strings or sequences of symbols that satisfy certain conditions.
Let us first consider the case where the two ones that are next to each other are at the beginning of the string. In this case, we can place the third one in any of the remaining positions, which are n-2, where n is the total length of the string. Therefore, the number of such strings is (n-2).
Similarly, if the two ones are at the end of the string, we can place the third one in any of the n-2 remaining positions, and the number of such strings is again (n-2).
Now let us consider the case where the two ones are in the middle of the string. In this case, we can place the two adjacent ones in (n-2) ways, and the third one can be placed in any of the remaining n-3 positions, since it cannot be adjacent to the other two ones. Therefore, the number of such strings is (n-2) x (n-3).
To get the total number of strings that satisfy the given condition, we need to add up the number of strings in each of the three cases:
Total number of strings = (n-2) + (n-2) + (n-2) x (n-3)
Simplifying this expression, we get:
Total number of strings = (n-1) x (n-2)

Find the total income produced by a continuous income stream in the first 2 years if the rate of flow is given by the following function, where t is time in years.
f(t)=300e^0.05t
(Round to the nearest dollar as needed.)
Therefore, the total income produced by the continuous income stream in the first 2 years is approximately $6631.
To find the total income produced by a continuous income stream in the first 2 years, we need to calculate the definite integral of the income function over the time interval [0, 2].
The income function is given by f(t) = 300e^(0.05t).
To calculate the definite integral, we integrate the function with respect to t and evaluate it at the limits of integration:
∫[0, 2] 300e^(0.05t) dt
Integrating the function, we have:
= [300/0.05 * e^(0.05t)] evaluated from 0 to 2
= [6000e^(0.052) - 6000e^(0.050)]
Simplifying further:
= [6000e^(0.1) - 6000]
Evaluating e^(0.1) ≈ 1.10517 and rounding to the nearest dollar:
= 6000 * 1.10517 - 6000 ≈ $6631

Answer:
x = 19 degrees
y = 84 degrees
Step-by-step explanation:
recall that for an isosceles triangle (which is pictured), the base angles have the same value.
In our case, we can see that the base angles are 48 deg and (3x-9) deg
if they are equal, we can equate them like this:
48 = 3x-9 (add 9 to each side)
48 + 9 = 3x
57 = 3x (divide both sides by 3)
x = 57/3
x = 19 degrees (answer)
also recall that the sum of the interior angles of a triangle add up to 180 deg, hence
48 deg + 48 deg + y deg = 180 deg
2(48) + y = 180
96 + y = 180
y = 180 - 96
y = 84 deg

1. One rule of thumb for estimating crowds is that each person occupies 2.5 square feet. Use this value to
determine the number of people that would fit in a room that is 216 in x 360in.
Answer:
216 people
Step-by-step explanation:
Given:
2.5 feet² is occupied by 1 person
Dimension of room = 216 in × 360 in
Required:
No. of people that would occupy the room
SOLUTION:
Step 1:
Convert the dimensions of the room from in to ft
Note: 1 foot = 12 inches
216 inches = \( \frac{216}{12} = 18 ft \)
360 inches = \( \frac{360}{12} = 30 ft \)
Step 2: calculate area of the room.
Area of the room = 30*18 = 540 ft²
Step 3: calculate the no. of people the room will contain.
2.5 ft² will contain one person
Therefore, 540 ft² will contain: \( \frac{540}{2.5} = 216 people \)
Find the limit. Use l'Hospital's Rule if appropriate. If there is a more elementary method, consider using it.lim x→[infinity] (ex + x)6/x
The limit of \((ex + x)^(^6^/^x^)\) as x approaches infinity is 1. As x becomes infinitely large, the exponential term dominates, resulting in the limit approaching 1.
To evaluate this limit, we can rewrite the expression as \((ex)^(^6^/^x^) * (1 + x/ex)^(^6^/^x^)\). As x approaches infinity, the first term \((ex)^(^6^/^x^)\)approaches 1 because the exponent tends to 0.
Now, let's focus on the second term \((1 + x/ex)^(^6^/^x^)\). As x approaches infinity, the x/ex term approaches 1, and we have \((1 + 1)^(^6^/^x^)\).
Taking the limit of this expression as x goes to infinity, we have \((2)^(^6^/^x^)\). Again, as x approaches infinity, the exponent tends to 0, resulting in (2)⁰, which is equal to 1.
Thus, the overall limit is given by the product of the limits of the two terms, which is 1 * 1 = 1.

FIND THE VOLUME OF EACH 3D FIGURE.
Here is an explanation to understand step by step how to do this.
A volume can be determined for any three-dimensional object using formulas that are unique to that item's shape. For instance, the volume of a water bottle indicates how much water it can hold. Understanding an object's volume is crucial since it indicates how much stuff that shape can carry.
Any form or object's volume is directly inversely proportional to the volume of water it displaces when submerged in water because of its link to density. As a result, there are two ways to determine an object's volume: by mathematically calculating it using the formula unique to that shape, or by submerging it in water and measuring the volumetric displacement of the water.
