The value of 5cos(tetha) + 4/sin(beta) is 9
What are complementary angles?Complementary angles are two angles that sum up to 90°. This means that in a right angled triangle sin( beta) is thesame as cos(90-tetha) and cos (beta) is sin(90-tetha).
Examples of complementary angles include: 30 and 60, 50 and 40 e.t.c
Therefore if tan ( tetha ) = 3/4, and tan(tetha) = opp/adj. This means opp is 3 and adj is 4
therefore hyp = √3²+4²
= √9+16 = √25
= 5
therefore cos(tetha) = 4/5
and sin beta = 4/5
therefore 5cos(tetha) + 4/sin(beta) = 5 × 4/5 +(4÷4/5)

A rectangle is drawn so the width is 47 inches longer than the heightIf the rectangle's diagonal measurement is 65 inches , find the height. Give your answer rounded to 1 decimal place.
The height of the rectangle is approximately 15.5 inches.
Let's call the height of the rectangle "h". We know that the width is 47 inches longer than the height, so the width can be expressed as "h + 47".
We can use the Pythagorean theorem to solve for the height. The Pythagorean theorem states that for a right triangle with legs of length "a" and "b" and hypotenuse of length "c", a^2 + b^2 = c^2.
In this case, we can consider the rectangle to be a right triangle, with the height as one leg, the width as the other leg, and the diagonal as the hypotenuse. So we can write:
h^2 + (h + 47)^2 = 65^2
Simplifying this equation gives:
2h^2 + 94h - 1476 = 0
We can solve for "h" using the quadratic formula:
h = (-b ± sqrt(b^2 - 4ac)) / 2a
In this case, a = 2, b = 94, and c = -1476. Plugging these values into the quadratic formula gives:
h = (-94 ± sqrt(94^2 - 4(2)(-1476))) / 4
Simplifying this expression gives:
h = (-94 ± sqrt(10084)) / 4
h = (-94 ± 100.42) / 4
h = -48.6 or 15.42
Since the height of the rectangle cannot be negative, we can discard the negative solution. Therefore, the height of the rectangle is approximately 15.5 inches.

Las llantas de la bicicleta de Julián miden 45 cm de diámetro y la distancia de su casa a la escuela es de 877 m cuántas vueltas aproximadamente deben de dar las llantas de la bicicleta de Julián para ir de su casa a la escuela
The tires of Julián's bicycle must take 620 turns to go from his house to school.
The circumference of the tire can be calculated using the formula C = πd, where d is the diameter of the tire.
C = πd = π(45cm) ≈ 141.37cm
To find out how many turns the tires must take, we need to divide the total distance by the distance covered by one revolution of the tire:
Number of turns = Distance / Circumference
Number of turns = 877m / (141.37cm/100cm/1m)
Number of turns ≈ 620.09
Therefore, the tires of Julián's bicycle must take approximately 620 turns to go from his house to school.

A pair of shoes usually sells for $67. If the shoes are 20% off, and sales tax is 5%, what is the total price of the shoes, including tax?
Answer:
If the shoes are 20% off, then the sale price of the shoes will be:
67 - 0.20 * 67 = 67 - 13.40 = 53.60
So the sale price of the shoes is $53.60.
If the sales tax is 5%, then the tax on the shoes will be:
0.05 * 53.60 = 2.68
So the tax on the shoes is $2.68.
To find the total price of the shoes including tax, we need to add the sale price of the shoes and the tax:
53.60 + 2.68 = 56.28
Therefore, the total price of the shoes, including tax, is $56.28.
Answer:
$56.28
Step-by-step explanation:
1. Find the shoes' sale price.
The shoes are 20% off. We will find the new price by first finding 20% of $67.
An easy way to do it:
10% of 67 = 6.7
20% of 67 = 13.4
to double the percentage of the first equation, double the answer.
Now that we know 20% of 67 we can take away 20% from it:
67 - 13.4 =53.6
Money uses 2 decimal points so we will add a 0 at the end of the result.
The price of the shoes with only the sale is $53.60.
2. Add sales tax
First find out 5% of $53.60.
An easy way to do it:
10% of 53.60 = 5.360
5% of 53.60 = 2.68
to half the percentage of the first equation, half the answer.
Now that we know the price of the tax we can add it to our shoe price. With the sale the shoe costs $53.60 and we will add our tax:
53.60 + 2.68 = 56.28

$56.28A coin is flipped 10 times and the sequence of heads and tails recorded. In how many ways can a sequence consist of exactly 3 heads and the rest tails?
there are 120 different ways a sequence of 10 coin flips can consist of exactly 3 heads and the rest tails.
To solve this problem, we can use the formula for combinations. The number of ways to choose k items from a set of n items is given by the formula n choose k, which is written as C(n,k) or sometimes as nCk.
In this case, we want to choose 3 heads from a set of 10 coin flips. The number of ways to do this is C(10,3) = 120.
Once we have chosen the 3 heads, the remaining 7 flips must all be tails. There is only one way to arrange 7 tails, since they are all the same.
Therefore, the total number of sequences that consist of exactly 3 heads and the rest tails is 120.

Breanna and Qasim plan to send their daughter to university. To pay for this they will contribute 8 equal yearly payments to an account bearing interest at the APR of 4%, compounded annually. Five years after their last contribution, they will begin the first of five, yearly, withdrawals of $51,100 to pay the university's bills. How large must their yearly contributions be?
Breanna and Qasim must contribute $22,583.39 per year for eight years to have enough money to pay for their daughter's university education.
To determine the yearly contribution required for Breanna and Qasim, we need to use the present value formula for an annuity.
The formula is:
PV = C * ((1 - (1 + r)⁻ⁿ) / r)
Where PV is the present value of the annuity, C is the annual contribution, r is the annual interest rate, and n is the number of years.
First, we need to calculate the present value of the contributions that Breanna and Qasim make for the first eight years. We can use the formula:
PV = C * ((1 - (1 + r)⁻ⁿ) / r)
Where C is the annual contribution, r is the annual interest rate, n is the number of years, and PV is the present value of the contributions.
We know that the annual contribution is the same for each of the eight years, so we can simplify the formula to:
PV = C * (((1 - (1 + r)⁻ⁿ) / r))
The present value of the contributions is equal to the future value of the withdrawals five years after the last contribution. We can use the future value formula for an annuity to calculate this:
FV = R * ((1 + r)ⁿ - 1) / r
Where FV is the future value, R is the annual withdrawal, r is the annual interest rate, and n is the number of years.
We know that the future value of the withdrawals is $51,100 per year, the interest rate is 4%, and the number of years is 5.
FV = 51,100 * ((1 + 0.04)⁵ - 1) / 0.04 = $246,387.19
This is the present value of the contributions that Breanna and Qasim make over the first eight years. We can now solve for the annual contribution required using the present value formula:
PV = C * (((1 - (1 + r)⁻ⁿ) / r))
$246,387.19 = C * (((1 - (1 + 0.04)⁻⁸) / 0.04))

f(x), because it eventually intersects g(x)
g(x), because it will not intersect f(x)
The function that is most likely increase exponentially is f(x). Because it eventually exceeds g(x)
To determine which function is most likely increasing exponentially, we need to compare the rate at which the two functions are increasing.
Looking at the table, we can see that as x increases, f(x) increases at a faster rate than g(x). In fact, f(x) eventually exceeds g(x) for x values greater than or equal to 5. This suggests that f(x) is increasing at an exponential rate.
On the other hand, g(x) is increasing at a much slower rate than f(x). Although g(x) is also increasing, it does not appear to be increasing exponentially. In fact, g(x) will never exceed f(x), because f(x) grows at a faster rate.
Therefore, the function that is most likely increase exponentially is f(x).

35 POINTS BY THE WAY
Answer: [1/5x-4+2y]+[2/5x+5-4y] simplifies to 3/5x - 2y + 1.
Step-by-step explanation:
To simplify the given expression, we need to combine like terms.
The like terms are the ones with the same variable parts.
Let's first simplify the expression inside the brackets separately:
[1/5x-4+2y] = 1/5x + 2y - 4
[2/5x+5-4y] = 2/5x - 4y + 5
Now, we can combine the simplified expressions:
[1/5x + 2y - 4] + [2/5x - 4y + 5]
= 1/5x + 2y - 4 + 2/5x - 4y + 5
= (1/5 + 2/5)x + (2y - 4y) - 4 + 5
= 3/5x - 2y + 1
Therefore, [1/5x-4+2y]+[2/5x+5-4y] simplifies to 3/5x - 2y + 1.
