The nth term of the sequence 28, 25 ,22, 19, 16 is aₙ=31-3n.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The given sequence is 28, 25 ,22, 19, 16

Twenty eight comma twenty five comma twenty two comma nineteen comma sixteen.

The sequence is an arithmetic sequence as there is a common difference between consecutive terms.

The first term is a=28

Common difference =25-28=-3

aₙ=28+(n-1)(-3)

aₙ=28-(n-1)(3)

aₙ=28-3n+3

aₙ=31-3n

Hence the nth term of the sequence 28, 25 ,22, 19, 16 is aₙ=31-3n.

Answer:

  3) 174°15'18"

  4) 34.859722...(repeating)°

  5) 434°, -286°

Step-by-step explanation:

There are 60 minutes in a degree, and 60 seconds in a minute.

3) To find minutes, multiply fractional degrees by 60:

  .255° = 0.255°×(60'/1°) = 15.3'

To find seconds, multiply fractional minutes by 60:

  0.3' = 0.3'×(60"/1') = 18"

Then the whole angle is ...

  174.255° = 174° 15' 18"

__

4) The conversion works the other way, too.

  34° 51' 35" = 34° +51(1/60)° +35(1/3600)° = (34 619/720)°

  = 34.8597222...° (a repeating decimal)

__

5) Add or subtract multiples of 360° to get co-terminal angles.

  74° +360° = 434°

  74° -360° = -286°

Here's your answer;

The word trigonometry is derived from two Greek words trigon and metron. Trigono means triangle and metron means measurement. Therefore in literal terms trigonometry is the measurement of the angles of a triangle. The application of trigonometry is very vast.It is used in measuring eight and distance, surveys,Map making, astronomy, engineering etc.

The longest side,which is the opposite side of right angle is the hypotenuse.There are two other side's,the opposite and the adjacent.The naming of these sides depends upon which angle is involved.The opposite is the side opposite the angle involved and it is called the perpendicular.

The adjacent is the side next to the angle involved(but not the hypotenuse) and it is called base.

Answer:

5.6

Step-by-step explanation:

We want to find the value of x, which is part of the segment that includes the length 10.

We need to use Power of Points, one property of which essentially says that if we have two intersecting chords such that they are each cut into two parts to make a and b, and c and d, then ab = cd (see attachment).

Here, we can say that a = 10, b = x, c = 7, and d = 8. Plug these in:

ab = cd

10 * x = 7 * 8

10x = 56

x = 56/10 = 5.6

The answer is 5.6.

Each diagonal has two parts (a, b, c, and d).

The formula is ab = cd

We have the values:

a = 10

b = x

c = 8

d = 7

Put these in the formula:

10x = (8)(7)

Solve for x.

10x = (8)(7)

10x = 56

10x/10 = 56/10

x = 5.6

Therefore, the answer is x = 5.6

Answer:percentage answer is 41.7% and for the fractions its 5/12

Step-by-step explanation:

for percentage to need to get the fraction to where the twelve in 7/12 is 100 so you multiply 8.3 to 12 and get 100 but you need to multiply it to the top too so you're left with 58.3/100 but that's the fraction of the goal made so what you do is subtract 58.3 from one hundred and you get 41.7 making your total 41.7%.

the way to solve the fraction is to start by subtracting the overall point to the points made and the sum would be the points missed and the point missed are 5/12 and that fraction is simplified to the max

Answer:

A = 1/2 b*h

b = 6

Step-by-step explanation:

The question is incomplete. The missing part is:

(A) We can use the geometric distribution with n = 100, k = 10, and p = 0.24 to calculate this probability. (B) We can use the binomial distribution with n = 10, k = 100, and p = 0.24 to calculate this probability. (C) We cannot calculate this probability using the binomial distribution since whether or not one flight is delayed is not independent of another. (D) We can use the binomial distribution with n = 100, k = 10, and p = 0.24 to calculate this probability

Solution:

In binomial probability, the assumption is that there is only one outcome for each trial. This is because the probability of success or failure is constant. Each trial is also independent of the other trial. This means that the probability of event A happening does not depend on the outcome of event B.

In the given scenario, the probability of a flight being delayed depends on the probability of the previous flight being delayed. It means that the outcomes are not independent. In geometric probability, a trial is repeated until success is achieved. The outcomes are also independent. Therefore, the correct option is

(C) We cannot calculate this probability using the binomial distribution since whether or not one flight is delayed is not independent of another.

The statement that is correct would be:

C). We cannot calculate this probability using the binomial distribution since whether or not one flight is delayed is not independent of another.

In the case of binomial probability, it is assumed that the outcome occurring for every trial would remain 1 only because there is consistency in terms of success or defeat.

This implies that the outcome of one will not impact the other's result.

Since the third statement shows that there is no possibility of estimating the probability by employing the method of binomial distribution as one flight's taking off or delay will not impact the other and they remain independent.

Thus, option C is the correct answer.

79+80+92+92+81+100+88+98+71+100+91+90

=1,062/12 = 88.5

Answer:

Option C

Step-by-step explanation:

Add all grades together:

79 + 80 + 92 + 92 + 81 + 100 + 88 + 98 + 71 + 100 + 91 + 90 = 1062

Divide the total by the number of grades in the set:

1062/12 = 88.5

The average of the grades is 88.5%, therefore Option C should be the correct answer.

Since the opposite sides are congruent then the figure is a parallelogram.

Answer:

See explanation below

Step-by-step explanation:

In this case, let's answer this by parts:

a) Concentration at time t when Co  is concentration at t = 0:

In this case, we will use the initial expression but without the 2, so:

C(t) = -kC

In this case, we want to know the concentration at time t so:

C'(t) = -kC(t)    derivating:

dC/dt = -kC

dC/C = -kdt   From here, we can do integrals so:

lnC = -kt + C₁   (1)

Now, it's time to replace t = 0 and C = C₀:

lnC₀ = -k(0) + C₁

lnC₀ = C₁   (2)

Replacing (2) in (1) we have:

lnC = -kt + lnC₀

lnC - lnC₀ = -kt

ln(C/C₀) = -kt

C/C₀ = e^(-kt)

C(t) = C₀ e^(-kt)   (3)

This is the expression for C at given time t.

2. time to eliminate 80% of the drug:

With the first data, we need to calculate the value of k, which will be constant at any given time so:

C(t) = C₀ e^(-kt)

0.5C₀ = C₀ e^(-30k)

0.5 = e^(-30k)

ln(0.5) = -30k

k = 0.02310

Now with this value we can calculate the time to eliminate 80% of the drug or simply in other words, that we just have a remaining of 0.2C₀:

0.2C₀ = C₀ e^(-0.0231t)

ln(0.2) = -0.0231t

-ln(0.2) / 0.0231 = t

t = 69.67 h

This is the time to eliminate 80% of the drug
