The time that the ball traveled is given as follows:

t = 2.5 seconds.

The quadratic function modeling the ball's height after t seconds is given as follows:

H(t) = -16t² + 40t.

To obtain the time traveled by the height, we must obtain the roots of the quadratic function, as follows:

-16t² + 40t = 0.

16t² - 40t = 0

t(16t - 40) = 0.

Hence the roots are:

Answer: B 133

Step-by-step explanation:

$63 + ($63 · 0.28) = $80.64

[tex]f = p + pm[/tex] where:

[tex]f[/tex] = final price: $80.64,

[tex]p[/tex] = original price: $63,

and [tex]m[/tex] = markup percent (in decimal): 28% → 0.28.

The value of y is 4.4.

Let's go through the steps to solve for y:

Distributive property:

[tex]1/5y + 2 - 4/5 = 1/2y - 1 + 1/10y[/tex]

Combine like terms:

[tex]1/5y + 2 - 4/5 = 1/2y - 1 + 1/10y[/tex]

Simplify the equation by getting rid of fractions. To do this, we can multiply every term by the least common denominator (LCD) of 10:

[tex]10 * (1/5y + 6/5) = 10 * (3/5y - 1 + 1/10y)[/tex]

Simplifying further:

[tex]2y + 12 = 6y - 10 + y[/tex]

Now, let's combine like terms again:

[tex]2y + 12 = 7y - 10[/tex]

Next, let's isolate the variable y. Subtract 2y from both sides and add 10 to both sides:

[tex]12 + 10 = 7y - 2y[/tex]

Simplifying:

22 = 5y

Finally, divide both sides by 5 to solve for y:

y = 22/5

Note: It's important to check our solution by substituting y = 4.4 back into the original equation to ensure it satisfies the equation.

The maximum error of the midpoint approximation is 0.55.

To estimate the maximum error, we can consider the worst-case scenario by assuming that the second derivative is at its maximum value throughout the interval [11, 31]. In this case, we can use the largest possible value for M.

To find the maximum error of the midpoint approximation, we need to determine the width of the interval and divide it by 2.

Width of the interval = upper bound - lower bound = 10.5 - 9.4 = 1.1

Maximum error (E) = (Width of the interval) / 2 = 1.1 / 2 = 0.55

Therefore, the maximum error of the midpoint approximation is 0.55.

You will need to pay $261.76 more each month if you want to pay off the balance in one year instead of three. However, you will save a total of $953.24 - $576 = $377.24 in interest by paying off the balance in one year instead of three.

If you decide to pay off the balance over one year instead of three, the payment amount will be higher, but the total interest paid will be lower due to the shorter repayment period.

First, let's calculate the total interest paid over three years. The total payment made over three years will be the monthly payment of $126.59 times 36 months, which is $4,553.24. The total interest paid is the difference between the total payment made and the initial balance of $3600, which is $953.24.

Now, let's consider paying off the balance over one year. The total payment made over one year will be the monthly payment of $126.59 times 12 months, which is $1,519.08. To calculate the interest paid, we can use the formula:

Total interest paid = Balance × Annual interest rate × Time

where the time is expressed in years. Plugging in the values, we get:

Total interest paid = $3600 × 0.16 × 1 = $576

Therefore, if you decide to pay off the balance over one year instead of three, you will pay an additional amount each month equal to the difference between the monthly payment for one year and the monthly payment for three years, which is:

Additional monthly payment = ($4,553.24/12) - ($1,519.08/12) = $261.76

This means that you will need to pay $261.76 more each month if you want to pay off the balance in one year instead of three. However, you will save a total of $953.24 - $576 = $377.24 in interest by paying off the balance in one year instead of three.

Given statement solution is:- The coordinates of point B is (3, 50°).

In the given scenario, we have point A with polar coordinates (2, 50°) and the pole O. We need to find point B such that OA is parallel to OB and OB has a length of 3 units.

Since OA and OB are parallel, they have the same angle with the positive x-axis. Therefore, the angle between OB and the positive x-axis would also be 50°.

To find the coordinates of point B, we can use the polar coordinates system, where the distance from the pole is denoted by r and the angle with the positive x-axis is denoted by θ.

Since OB has a length of 3 units, the distance from the pole (r) would be 3. The angle between OB and the positive x-axis is also 50°. Therefore, the coordinates of point B would be (3, 50°).

To determine the optimal number of matted and unmatted pictures to maximize the company's profit, we can set up a linear programming problem.

Let's denote:

- x: the number of matted pictures

- y: the number of unmatted pictures

The objective is to maximize the profit, which can be expressed as:

Profit = 40x + 35y

We need to consider the following constraints:

1) The number of pictures completed each day cannot exceed 36:

x + y ≤ 36

2) The total man-hours of labor cannot exceed 80:

4x + 2y ≤ 80

3) The number of pictures cannot be negative:

x, y ≥ 0

Now we can solve this linear programming problem to find the optimal values for x and y.

First, let's graph the feasible region defined by the constraints:

```

x + y ≤ 36

4x + 2y ≤ 80

x, y ≥ 0

```

The feasible region is the area of the graph that satisfies all the constraints.

Next, we need to evaluate the objective function (Profit = 40x + 35y) at the vertices of the feasible region to find the maximum profit.

We can use different methods such as the corner-point method or the simplex method to determine the vertices and evaluate the profit at each vertex.

Thus, once we find the vertex that yields the maximum profit, we will have the optimal values for x and y.

3. The probability that excessive radiation will be missed simultaneously by both sensors is 0.0001 or 0.01%.

The probability of a false alarm is 0.02.

The probability of a miss is 0.01.

P(false alarm or miss)

= P(false alarm) + P(miss)

= 0.02 + 0.01 = 0.03

Therefore, the probability that the sensor will give an incorrect report is 0.03 or 3%.

2. Probability of simultaneous false alarms by both sensors:

P(false alarm by both sensors)

= P(false alarm by sensor 1) * P(false alarm by sensor 2)

= 0.02 * 0.02

= 0.0004

Therefore, the probability that the reactor will be shut down because of simultaneous false alarms by both sensors is 0.0004 or 0.04%.

3. Probability of missing excessive radiation by both sensors:

P(miss by both sensors)

= P(miss by sensor 1) * P(miss by sensor 2)

= 0.01 * 0.01

The probability that exactly four out of 19 adults say cashews are their favorite nut is approximately 0.251.

The probability that 12 or more stolen bikes will be returned is approximately 0.026 (rounded to the nearest thousandth).

To solve both of these probability problems, we can use the binomial probability formula:

P(X = k) = (n C k) × p^k × (1 - p)^(n - k)

where:

P(X = k) is the probability of getting exactly k successes

n is the total number of trials

k is the number of desired successes

p is the probability of success in a single trial

(1 - p) is the probability of failure in a single trial

(n C k) represents the binomial coefficient, calculated as n! / (k! x (n - k)!)

Let's solve each problem separately:

The probability that exactly four out of 19 adults say cashews are their favorite nut can be calculated as:

P(X = 4) = (19 C 4) ⁴(0.49⁴) (0.51¹⁵)

Using the binomial probability formula, we can calculate:

P(X = 4) ≈ 0.251

Therefore, the probability that exactly four out of 19 adults say cashews are their favorite nut is approximately 0.251.

To find the probability that 12 or more stolen bikes will be returned out of 335 stolen bikes, we can use the binomial probability formula. Let's denote the probability of a stolen bike being returned as p = 0.03, the number of trials as n = 335, and the number of desired successes as k = 12 or more.

Using the complement rule, we can calculate the probability of not getting 11 or fewer successes:

P(X ≥ 12) = 1 - [P(X = 0) + P(X = 1) + ... + P(X = 11)]

To perform the calculation, summing up individual probabilities can be time-consuming. However, using statistical software or a binomial probability calculator can provide a convenient solution.

Using such a calculator, we find that the probability of 11 or fewer stolen bikes being returned is approximately 0.974. Therefore, the probability of 12 or more stolen bikes being returned is:

P(X ≥ 12) = 1 - 0.974 ≈ 0.026

Thus, the probability that 12 or more stolen bikes will be returned is approximately 0.026 (rounded to the nearest thousandth).
