An object is dropped from 40 feet below the tip of the pinnacle atop a 716​-ft tall building. The height h of the object after t seconds is given by the equation h=−16t2+676. Find how many seconds pass before the object reaches the ground.

Answer:

x ≤ 135/2

Step-by-step explanation:

x is the cost per night. You have to pay for 2 nights, and you do not want to spend more than $135 total. Another way to say that, is you want to spend less than or equal to $135.

x = cost per night

2 = number of nights

2x = total cost

Total cost must be less than or equal to $135.

2x ≤ 135

Divide each side by 2.

x ≤ 135/2

Answer: (2, 18)

Step-by-step explanation:

When x=2, [tex]f(2)=2(3)^{2}=18[/tex].

So, it should pass through (2, 18).

Step-by-step explanation:

I took the test.

The domain of the function is [1,  ∞) and the range is [0,  ∞)

The equation of the function is given as:

g(x) = 3√x - 1

The domain is the possible values of x.

Set the radicand to greater than or equal to 0

x - 1 >= 0

Add 1 to both sides

x >= 1

This can be rewritten as:

[1,  ∞)

Breakdown

g(x) = 3√x - 1

x - 1 >= 0

x >= 1

[1,  ∞)

The range is the possible values of y.

Set the radicand to 0

g(x) = 3 * 0

Evaluate the product

g(x) = 0

This can be rewritten as:

[0,  ∞)

Breakdown

g(x) = 3√x - 1

g(x) = 3 * 0

The green mathematics tells about the impulse response of an in homogeneous linear differential operator.

According to the statement

we have to explain the green mathematics.

In mathematics, Actually there is a Green Function which was founded by a mathematician George Green.

In this function, a Green's function is the impulse response of an in homogeneous linear differential operator defined on a domain with specified initial conditions or boundary conditions.

The example of green function is the Green's function G is the solution of the equation LG = δ, where δ is Dirac's delta function; the solution of the initial-value problem Ly = f is the convolution (G ⁎ f), where G is the Green's function.

Actually in this function, it gives the relationship between the line integral of two dimensional vector over a closed path by a integral.

In this there is a green theorem, which  relates a line integral around a simply closed plane curve C and a double integral over the region enclosed by C.

The values which would help complete the table according to the complete part of the task content are as evaluated.

First, the total number of average players can be evaluated by summing up the total number of players vertically as follows;

180 + average + 80 = 600

The number of average players is therefore; 600-180-80 = 340 average players.

Also, the number of female expert players can be evaluated vertically as;

50 + 50 + female expert = 150

Female expert = 150-50-50 = 50 female experts.

The number of male novice players can be evaluated horizontally as;

Male novice + 50 = 180

Male novice = 180 - 50 = 130.

The number of average male players is therefore easily evaluated vertically as;

130 + male average + 30 = 600

male average = 600-130-30 = 440.

We know that Paolo worked (2 + 3/4) hours this week, and that is equivalent to (1 + 5/6) shifts.

Step-by-step explanation:

a scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures.

because all 3 angles must be different, they cannot be congruent.

because if angles are congruent, it means that they are of equal size.

the desired definition is a paradox or oxymoron. it contradicts itself and can never be true.

Answer:

it cannot have all angles congruent: impossible.

Step-by-step explanation:

by the definition scalene, it means no angle is the same length. meaning, to have all the sides congruent (the same length) that would be impossible and it can never happen. if you would like a congruent triangle, an isosceles or equilateral is the triangle you're looking for.

Answer:

x = -7 and x = 4.

Step-by-step explanation:

f(x) = x^2 + 3x - 28

= (x + 7)(x - 4).

The reciprocal of f(x) can be written as

1 / (x + 7)(x - 4).

When the denominator is zero we have vertical asymptotes

so they are x = -7 and x = 4.

A relationship between two variables in which the variables vary in the opposite direction (i.e., one increases while the other decreases, or vice versa) is referred to as a negative correlation.

When two variables move in opposite sizes and directions from one another, so that when one increases, the other drops, and vice versa, this is referred to as having a negative correlation or inverse correlation.

In order for investors to profit from price increases in some assets when others decline, negative correlation is used when building diverse portfolios.

Answer:

  a) payment: $1677.99

  b) total repaid: $604,076.40

  c) saved: $168,231.60

Step-by-step explanation:

The amortization formula can be used to find the monthly payment on the loan. The total repaid will be the sum of payments made. The amount saved will be the difference between the total repaid amounts for the different loans.

The payment A on a loan of principal P at annual rate r for t years is given by ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

The loan of interest is for $425,000 × (1 -30%) = $297,500. Then the payments on a 30 year loan are ...

  A = $297,500(0.0544/12)/(1 -(1 +0.0544/12)^-360) ≈ $1677.99

For a 15-year loan, the payments are ...

  A = $297,500(0.0544/12)/(1 -(1 +0.0544/12)^-180) ≈ $2421.36

The above calculation shows the monthly payment is $1677.99.

The total repaid is the sum of 360 monthly payments:

  360×$1677.99 = $604,076.40

The total repaid is the sum of 180 monthly payments:

  180×$2421.36 = $435,844.80

and the savings is ...

  $604,076.40 -435,844.80 = $168,231.60

__

Additional comment

We are asked to round to the nearest cent. The payment amounts here are accurately calculated to that precision. The total repaid on an actual loan will be slightly different, because the final payment will be slightly different.

The 30-year mortgage will have a slightly lower final payment because the monthly amount is rounded up. The 15-year mortgage will have a slightly higher final payment because the monthly amount is rounded down.

Overall, this means the totals of payments shown here, and their difference, vary slightly from the reality of loans of this kind. (They're probably not accurate to the nearest cent.)

Even using the "exact" payment value may not give the actual loan values. This is because the actual amortization schedule is rounded to the nearest cent each month. The cumulative effect of this rounding seems to be calculable only by figuring the 360 (or 180) actual monthly balance amounts.

We have calculated the answers in the manner we suppose is expected. Producing an actual amortization spreadsheet is a bit more work.

The probability that each guest of each type m+n will receive a roll is 79.

Given that the breakfast should have consisted of three types of rolls, one each of the nut, cheese and fruit rolls, and the cook should have wrapped each of the nine rolls.

The denominator of m/n equals the total number of possible role configurations assigned to the three people. It [tex]${9 \choose 3}{6 \choose3}$[/tex] is the same as the number of ways to choose three roles out of 9 to give to the first person [tex]${9 \choose 3}$[/tex], and three rolls of 6 [tex]${6 \choose3}$[/tex]. After that, the remaining three roles have no more configurations.

The numerator is the number of ways to assign a roll of each type to each of the three people, which can be done by defining the three types of roles such as flavored x, flavored y and flavored z.

xxx, yyy, zzz

So we have to choose one x, one y and one z to give to the first person. There are 3x, 3y and 3z to choose from, resulting in 3³ combinations. Multiply that by the combinations of xs, ys and zs for the second person, which is clearly 2³ since there are two of each letter left. simplify to our fraction m / n, which is 9/70. If you add them together, you get 9 + 70 = 79.

Thus, the probability that each guest has obtained a roll of each type is m / n, where m and n are relatively prime, so m + n is 79.
