Using trigonometric identities, the simplified expression, without quotients, is given as follows:
A. [tex]\cos{\beta}\cot{\beta}[/tex]
Which trigonometric identities are used to solve this question?The cosecant of an angle is given by one divided by the sine of the angle, hence:
[tex]\csc{\beta} = \frac{1}{\sin{\beta}}[/tex]
The sine and the cosine of an angle are related as follows:
[tex]\sin^2{\beta} + \cos^2{\beta} = 1[/tex]
[tex]\cos^2{\beta} = 1 - \sin^2{\beta}[/tex]
The cotangent of an angle is:
[tex]\cot{\theta} = \frac{\cos{\theta}}{\sin{\theta}}[/tex]
Which is the simplified expression?The expression given is:
[tex]\csc{\beta} - \sin{\beta}[/tex]
Simplifying the cosecant:
[tex]\csc{\beta} - \sin{\beta} = \frac{1}{\sin{\beta}} - \sin{\beta} = \frac{1 - \sin^{2}\beta}{\sin{beta}}[/tex]
Then, applying the last two identities in the subsection above to remove the quotient, the simplified expression will be found as follows:
[tex]\frac{1 - \sin^{2}\beta}{\sin{beta}} = \frac{\cos^2{\beta}}{\sin{\beta}} = \frac{\cos{\beta}}{\sin{\beta}} \times \cos{\beta} = \cos{\beta}\cot{\beta}[/tex]
Hence option A is correct.

A red and a blue die are thrown. Both dice are fair. The events A and B are defined as follows:
A: The blue die shows a number greater than 2.
B: The red die shows a number less than 5
What is p(A|B)? (Round to four decimal places.)
P(A|B) read as the probability of the event A given the event B is equal to 0.5000 rounded up to four decimal place.
What is conditional probabilityConditional probability is known as the possibility of an event or outcome happening, based on the existence of a previous event or outcome. The conditional probability P(A|B) occur only in the case of dependent events. It gives the conditional probability of A given that B has occurred.
P(A|B) = P(A∩B) / P(B)
P(A∩B) = Probability of happening of both A and B
When a die is rolled, the sample space = {1, 2, 3, 4, 5, 6}.
A is the event the blue die shows a number greater than 2, So;
A = {3, 4, 5, 6}
B is the event the red die shows a number less than 5. So;
B = {1, 2, 3, 4}.
Then A∩B = {3, 4}
P(A∩B) = 2/6 = 1/3
P(B) = 4/6 = 2/3
P(A|B) = 1/3 ÷ 2/3
P(A|B) = 1/3 × 3/2 {changing division to multiplication}
P(A|B) = 1/2
Therefore, the conditional probability of the event A given the event B denoted by P(A|B) is equal to 1/2 or 0.5000 to four decimal place.

Answer: If the model kit for the Dornier Do17 airplane has a wingspan of 10 inches and the scale of the kit is 1 inch to 72 inches. This means that for every inch on the model, the equivalent measurement on the actual Dornier Do17 airplane is 72 inches.
We know that the wingspan of the model is 10 inches and we want to find the actual wingspan of the airplane so we'll use the scale factor of 1:72
To find the actual wingspan, we'll multiply the wingspan of the model by the scale factor.
10 inches * 72 inches/1 inch = 720 inches
Therefore, the actual wingspan of the Dornier Do17 airplane is 720 inches or 60 feet.

The triangle has length of the side h is equal to 97.1 inches approximately to the nearest tenth, using the sine rule.
What is the sine ruleThe sine rule is a relationship between the size of an angle in a triangle and the opposing side.
For the triangle ΔGHI, by sine rule;
g/sinG = h/sinH = i/sinI
We first derive the angle G as follows:
151° + 7° + G = 180° {sum of interior angles of a triangle}
G = 180° - 158
G = 22°
Hence by sine rule;
75/sin22° = h/sin151°
h = (75 × sin151°)/sin22° {cross multiplication}
h = 97.1

End Balance: $3,839.25 + $2,579.20 - $2,190.05 = $5,735.15, so the reconciled balance of $5,735.15.
What is bank reconciliation theory?This theory is used to compare the bank statements to the check register in order to properly reconcile the two balances.
The theory used in this question is the bank reconciliation theory.
Step 1: Begin by looking at the two balances - the check register balance and the bank statement balance.
In this case, the check register balance is $3,839.25 and the bank statement balance is $3,450.10.
Step 2: Add up all of the deposits that are not reported on the bank statement. In this case, the deposits are $2,000, $135.67, $254.77, and $188.76.
Step 3: Subtract all of the checks that are not reported on the bank statement. In this case, the checks are $567.89, $23.83, $598.33, and $1,000.
Step 4: Add the deposits and subtract the checks from the check register balance.
In this case, the check register balance ($3,839.25) plus the deposits ($2,579.20) minus the checks ($2,190.05) gives a reconciled balance of $5,735.15.

a) The sequence is geometric,b) [tex]t(n) = 2^{4-n}[/tex]----------------------------------------
Given sequence from zeros to 6th terms:
16, 8, 4, 2, 1, 1/2, 1/4It is a GP with the common ratio of 1/2 as each term is half the previous one.
Use the nth term equation, considering the first term is t(1) = 8, and common ratio r = 1/2:
[tex]t(n) = t(1)*r^{n-1}[/tex][tex]t(n) = 8*(1/2)^{n-1}=8*2^{1-n}=2^3*2^{1-n}=2^{4-n}[/tex]Answer:
a) Geometric sequence
[tex]\textsf{b)} \quad t(n)=8 \left(\dfrac{1}{2}\right)^{n-1}[/tex]
Step-by-step explanation:
An Arithmetic Sequence has a constant difference between each consecutive term.
A Geometric Sequence has a constant ratio (multiplier) between each consecutive term.
Part (a)From inspection of the given table, t(n) halves each time n increases by 1.
Therefore, the sequence is geometric with a common ratio of 1/2.
Part (b)[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Geometric sequence}\\\\$a_n=ar^{n-1}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\\phantom{ww}$\bullet$ $r$ is the common ratio.\\\phantom{ww}$\bullet$ $a_n$ is the $n$th term.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]
Given:
a = 8r = 1/2aₙ = t(n)Substitute the initial value (when n = 1) and the common ratio into the formula to create an equation for the nth term:
[tex]\implies t(n)=8 \left(\dfrac{1}{2}\right)^{n-1}[/tex]
ella has 0.5 lb of sugar how much water should she add to make the following concentrations? tell ella how much syrup she will have in each case. 75% syrup ella should add _ lb water and she will have to add _lb syrup
Answer: The answer provided is based on the following calculation:
To make a 75% syrup, Ella should add enough water to the sugar to create a solution that is 25% sugar and 75% water.
To calculate how much water to add, you can use the formula: (desired % of sugar) / (100 - desired % of sugar) * (amount of sugar).
In this case, it would be: (0.75) / (100 - 0.75) * (0.5 lb) = 0.67 lb of water.
To calculate the total amount of syrup, you add the amount of sugar and the amount of water: 0.5 lb + 0.67 lb = 1.17 lb.
So Ella should add 0.67 lb of water to make a 75% syrup and will have a total of 1.17 lb syrup.
Step-by-step explanation:
Answer:
for the 75% syrup: 0.167lbs
For the 1.5% syrup: 32.83 lbs
"Find all the second partial derivatives
f(x,y)= sin^(2) (mx+ny)"
Therefore , the solution to the given problem of derivative comes out to be 2cos(mx+ny) for both the cases of partial derivative.
Define derivative.The definition of a derivative is the simultaneous change that occurs at a certain place. Implicit & explicit functions are typically distinguished from one another. Explicit functions are those where the value of the known individual entity "x" directly determines the value of the known dependent variable "y."
Here,
Given : f(x,y)= sin^(2) (mx+ny)"
Partial derivative with respect to x
=> dx/dy = 2sin (mx+ ny) *m
=> d²x/dy = 2cos(mx+ny)
Partial derivative with respect to y
=> dx/dy = 2sin (mx+ ny) *n
=> d²x/dy = 2cos(mx+ny)
Therefore , the solution to the given problem of derivative comes out to be 2cos(mx+ny) for both the cases of partial derivative.
