48/8 and do the same to the other 27/8

So when you see it takes 27/8 for one you know she can only do one full serving.

21/8 is what's left

So 2 5/8 is left

The vertex of the parabola is (8, -1), and the axis of symmetry is x = 8.

To determine the vertex and axis of symmetry of the parabola y = x^2 - 16x + 63, we can use the formula:

x = -b / (2a)

Comparing the given equation to the standard form of a quadratic equation (y = ax^2 + bx + c), we can identify that a = 1, b = -16, and c = 63.

Using the formula, we substitute the values:

x = -(-16) / (2 * 1)

x = 16 / 2

x = 8

The x-coordinate of the vertex is 8. To find the y-coordinate, we substitute this value back into the original equation:

y = (8)^2 - 16(8) + 63

y = 64 - 128 + 63

y = -1

The vertex of the parabola is (8, -1). The axis of symmetry is the vertical line passing through the vertex, which is x = 8.

Answer:

7.86seconds

Step-by-step explanation:

Given the expression used to model the length of the pendulum as

L=0.81t^2 where t is the period

IF the pendulum is 50 feet long, then L = 50 feet

Substitute

50  = 0.81t^2

t² = 50/0.81

t² = 61.7283

t = 7.86 seconds

The maximum height attained by a projectile that moves upward and then falls back to its starting location is known as the maximum height.

The initial velocity of the tennis ball that is fired vertically upward from the ground is 29 m/s, and the acceleration due to gravity \(is -9.81 m/s^2\).Let's calculate the maximum height first .Maximum height \((h) = u²/2g\) (where u is the initial velocity and g is the acceleration due to gravity)\(h = (29)²/(2 × 9.81)= 42.24\)meters So, the maximum height that the tennis ball can reach is 42.24 meters.

the formula\(v = u + gt, we can determine the velocity of the tennis ball after 3 seconds. v = u + gtv = 29 + (-9.81 × 3)v = 29 - 29.43v = -0.43 m/s\)Therefore, the velocity of the tennis ball after 3 seconds is -0.43 m/s (downward).Hence, the answer is that the velocity of the ball after 3.0 seconds of the acceleration due to gravity is -0.43 m/s.

The expression (6u + 7v) · V simplifies to 42 + 14v · V.

First, let's find the value of (6u + 7v) · V using the given information:

Since ||v|| = 2, we know that v · v = ||v||^2 = 2^2 = 4.

Similarly, ||u|| = 7, so u · u = ||u||^2 = 7^2 = 49.

Now, let's expand the expression (6u + 7v) · V using the dot product properties:

(6u + 7v) · V = (6u · V) + (7v · V)

Since u · y = 3, we can substitute it in the equation:

(6u · V) + (7v · V) = (6(3) + 7v · V) = 18 + 7v · V

Finally, we need to simplify the expression 7v · V. Using the dot product properties, we have:

v · V = ||v|| * ||V|| * cos(θ)

Since ||v|| = 2 and ||V|| = 2 (from ||v|| = 2), and cos(θ) is the cosine of the angle between v and V, which can range from -1 to 1, we can simplify the expression to:

v · V = 2 * 2 * cos(θ) = 4 * cos(θ)

Therefore, the final simplified expression is:

(6u + 7v) · V = 18 + 7(4 * cos(θ)) = 18 + 28cos(θ) = 42 + 14v · V.

Step-by-step explanation:

The estimated federal income tax withholding using the percentage method for the given scenario would be $1,940 + $1,680 = $3,620.

To calculate the federal income tax withholding using the percentage method, we need the specific tax rates and brackets for the given income level. The tax rates and brackets may vary depending on the tax year and filing status.

Since you mentioned using the pre-2020 Form W-4, I will assume you are referring to the 2019 tax year. In that case, I can provide an estimate based on the tax rates and brackets for that year.

For a married employee filing jointly in 2019, the federal income tax rates and brackets are as follows:

- 10% on taxable income up to $19,400

- 12% on taxable income between $19,401 and $78,950

- 22% on taxable income between $78,951 and $168,400

- 24% on taxable income between $168,401 and $321,450

- 32% on taxable income between $321,451 and $408,200

- 35% on taxable income between $408,201 and $612,350

- 37% on taxable income over $612,350

To calculate the federal income tax withholding, we need to determine the taxable income based on the employee's earnings and filing status. Assuming no other deductions or adjustments, the taxable income can be calculated as follows:

Taxable Income = Earnings - Standard Deduction - (Withholding Allowances * Withholding Allowance Value)

For the 2019 tax year, the standard deduction for a married couple filing jointly is $24,400, and the value of one withholding allowance is $4,200.

Using the given information of earning $62,000 and claiming 1 federal withholding allowance, we can calculate the taxable income:

Taxable Income = $62,000 - $24,400 - (1 * $4,200) = $33,400

Now we can apply the tax rates to determine the federal income tax withholding:

10% on the first $19,400 = $19,400 * 10% = $1,940

12% on the remaining $14,000 ($33,400 - $19,400) = $14,000 * 12% = $1,680

Therefore, the estimated federal income tax withholding using the percentage method for the given scenario would be $1,940 + $1,680 = $3,620.

The p-value of a test statistic is the probability of observing a test statistic as extreme or more extreme than the one calculated, assuming the null hypothesis is true.

In this case, since the alternative hypothesis is "<0", we would be looking for the probability of observing a test statistic less than 1.37.

To determine the p-value, one would need more information about the distribution of the test statistic, such as the degrees of freedom, sample size, and the type of test being performed. With this information, one could use a statistical table or software to determine the p-value.

It's worth noting that a p-value of 0.05 or less is commonly used as a threshold for statistical significance, meaning that if the p-value is below 0.05, the null hypothesis is rejected in favor of the alternative hypothesis.

However, this threshold is arbitrary and the choice of a significance level depends on the specific context and research question being addressed.

  110°

Step-by-step explanation:

The total of the ratio units is 11 +2 +5 = 18. These stand for the total of angles, 180°, so each ratio unit stands for 180°/18 = 10°.

The largest angle is 11 ratio units, or 11×10° = 110°.

The sequence {cn} is convergent with limit 2 and the sequence {dn} is convergent with limit 20.

The first sequence {an} is defined as, an = 1 + 4/n. Using the e-N definition, we will show that this sequence converges to 1.Suppose ε > 0.

We need to find a natural number N such that |an – 1| < ε for all n > N.To do this, we can write |an – 1| = |1 + 4/n – 1| = |4/n| = 4/n, since 4/n > 0.

We want to find N such that 4/n < ε. Solving for n, we have n > 4/ε. This means we can take N to be any natural number greater than 4/ε.

Then for all n > N, we have |an – 1| < ε. Therefore, by the e-N definition of limits, we have an → 1 as n → ∞.
The second sequence {cn} is defined as cn = 2an + bn. Since {an} and {bn} are convergent with limits 3 and -4, respectively, we have cn → 2(3) + (-4) = 2 as n → ∞.

Therefore, {cn} converges to 2.The third sequence {dn} is defined as dn = anbn + 4a².

Since {an} and {bn} are convergent with limits 3 and -4, respectively, we have dn → 3(-4) + 4(3)² = 20 as n → ∞. Therefore, {dn} converges to 20.

Therefore, the sequence {cn} is convergent with limit 2 and the sequence {dn} is convergent with limit 20.

In a 1-year semi-annually paid interest rate swap, with a notional amount of £1,000,000, the swap rate is 3.0%. The floating rate is based on the 6-month LIBOR plus 1%. The market rate refers to the prevailing interest rate for the specified time period.

An interest rate swap involves the exchange of cash flows between two parties based on different interest rate benchmarks. In this case, the swap has a 1-year maturity and payments are made semi-annually.

The fixed rate, also known as the swap rate, is determined at the beginning of the swap agreement and remains fixed throughout the swap's duration. In this scenario, the swap rate is 3.0%.

The floating rate is determined by a reference rate plus a spread. The reference rate used here is the 6-month LIBOR (London Interbank Offered Rate), which is a widely used benchmark for short-term interest rates. The floating rate in this swap is the 6-month LIBOR plus 1%.

The market rate refers to the prevailing interest rate for the specified time period. It represents the current market conditions and influences the pricing and valuation of the interest rate swap.

To fully analyze the swap and its implications, further calculations and considerations, such as the present value of cash flows and potential valuation changes based on market rate movements, would be necessary.
