when the sun is 35° above the horizon. how long is the shadow cast by a building 15 metres high?
Therefore , the solution of the given problem of trigonometry comes out to be approximately 21.424 metres long when the sun is 35 degrees above the horizon.
What is trigonometry?Some people assert that the growth of astrophysics was influenced by the merging of various fields. Many metric problems can be solved or the result of a calculation can be ascertained with the use of exact mathematical techniques. Trigonometry is the study of the six basic geometric calculations from a scientific perspective. They go by many other names and acronyms, including sine, variance, direction, and others. (csc).
Here,
When the sun is at a 35° elevation angle and the structure is 15 metres tall, we want to determine the length of the shadow (on the next side).
Let x represent the desired shadow's length. Next, we have
=> tan 35° = 15/x
When we multiply both sides by x, we obtain:
=> x tan 35° = 15
By dividing both sides by 35° of tan, we obtain:
=> x = 15 / tan 35°
We may calculate the value of the tangent of 35 degrees using a calculator:
=> tan 35° ≈ 0.7002
Next, we have
=> 15x/0.702x=21.424 metres
Consequently, a building 15 metres high will create a shadow that is approximately 21.424 metres long when the sun is 35 degrees above the horizon.

Emma brought $23.75 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1 /4 as much as the sketchbook, and the sketchbook cost 2/ 3 the cost of the paint set. Emma had $4.50 left over after buying these items.
Emma bought a brush for $1.75, a sketchbook for $7, and a paint set for $10.5.
How to solve for the costB = 1/4 * S
S = 2/3 * P
B + S + P = 23.75 - 4.50
Emma spent 23.75 - 4.50 = $19.25 on the brush, sketchbook, and paint set.
Now we have the equation:
B + S + P = 19.25
Substitute the expressions from relationships 1 and 2 into the equation:
(1/4 * S) + S + (3/2 * S) = 19.25
Now combine the terms:
(1/4 * S) + (4/4 * S) + (6/4 * S) = 19.25
(11/4 * S) = 19.25
Now, to solve for S, multiply both sides of the equation by the reciprocal of the fraction (4/11):
S = (4/11) * 19.25
S = 7
The sketchbook cost $7. Now we can find the costs of the brush and the paint set using relationships 1 and 2:
B = 1/4 * S = 1/4 * 7 = 1.75
P = 3/2 * S = 3/2 * 7 = 10.5

Answer:
(x, -1/2x + 5/2) or infinitely many solutions
Step-by-step explanation:
We can solve the system of equations using substitution. We can start by isolating x in the first equation. Then, we can plug in the entire equation made from isolating for x in the second equation, which will allow us to find y:
Isolating:
x = -2y + 5
Plugging in and solving for y:
4(-2y + 5) + 8y = 20
-8y + 20 + 8y = 20
20 = 20
We see that we get a constant equal to another constant. Whenever you get this as a solution to a system of equations, this means that there are infinitely many solutions. We can express the general rule for the solution in coordinate form by isolating y in at least one of the equations:
y = -1/2x + 5/2
Thus, the general rule for the solution to the system of equations is
(x, -1/2x + 5/2), so you can either put this general rule as the answer or write solution = infinitely many solutions
You can see that there are infinitely many solutions by plugging in any number for x into the two equations and see that you get 5 for the equation and 20 for the second equation. Let's try 4 for x and 0 for x:
4 for x in first equation:
4 + 2(-1/2(4) + 5/2) = 5
4 + 2(0.5) = 5
4 + 1 = 5
5 = 5
4 for x in the second equation
4(4) + 8(-1/2(4) + 5/2) = 20
16 + 8(0.5) = 20
16 +4 = 20
20 = 20
0 for x in the first equation:
0 + 2(-1/2(0) + 5/2) = 5
0 + 2(2.5) = 5
5 = 5
0 for x in the second equation:
4(0) + 8(-1/2(0) + 5/2) = 20
0 + 8(2.5) = 20
20 = 20
Kelly bought a new SUV for $28,000. She made a down payment of $11,000 and has monthly payments of $332.63 for 5 years. She is able to pay off her loan at the end of 36 months. Using the actuarial method, find the unearned interest and payoff amount.
The unearned interest and the payoff amount is $11,022.12 and $18,784.87 respectively
Given data ,
Kelly bought a new SUV for $28,000. She made a down payment of $11,000 and has monthly payments of $332.63 for 5 years.
She is able to pay off her loan at the end of 36 months.
Now , Total interest = (monthly payment x number of months) - loan amount
Total interest = ($332.63 x 60) - $17,000
Total interest = $19,957.80
Next, we need to calculate the interest that has already been paid over the first 36 months of the loan. We can use the formula:
Interest paid = (monthly payment x number of months) - (loan amount - down payment)
Interest paid = ($332.63 x 36) - ($28,000 - $11,000)
Interest paid = $8,935.68
The unearned interest is the difference between the total interest and the interest paid so far:
Unearned interest = total interest - interest paid
Unearned interest = $19,957.80 - $8,935.68
Unearned interest = $11,022.12
To find the payoff amount, we need to add the remaining principal balance to the unearned interest:
Payoff amount = remaining balance + unearned interest
To calculate the remaining balance, we can use the formula for the present value of an annuity:
Remaining balance = monthly payment x (1 - (1 + r)^-n) / r
Where r is the monthly interest rate and n is the number of remaining months. We can solve for r by using the total interest calculated earlier:
r = (Total interest / loan amount) / 12
r = ($19,957.80 / $17,000) / 12
r = 0.0986%
Using this interest rate and n = 24 (the remaining 24 months of the loan), we can calculate the remaining balance:
Remaining balance = $332.63 x (1 - (1 + 0.0986%)^-24) / 0.0986%
Remaining balance = $7,762.75
Payoff amount = $7,762.75 + $11,022.12
Payoff amount = $18,784.87
Hence , the interest is solved

Encik Halim bought 108 lemons to sell at his grocery shop. He packed 3 lemons in small packets and sold at the price of RM6.80 per packet. If he made a total profit of RM88.20, calculate the price of each lemon bought by him.
Answer:
the price of each lemon bought by Encik Halim is RM1.45.
Step-by-step explanation:
Encik Halim bought 108 lemons and packed them into packets of 3 lemons each. So he made a total of 108/3 = 36 packets.
Let's assume that the cost of each lemon bought by Encik Halim is x RM.
The total cost of 108 lemons would then be 108x RM.
Encik Halim sold each packet at a price of RM6.80, so the total revenue he earned from selling 36 packets would be 36 x RM6.80 = RM244.80.
We are told that Encik Halim made a profit of RM88.20 from the sale of these packets, so his total cost would be:
Total cost = Total revenue - Profit
Total cost = RM244.80 - RM88.20
Total cost = RM156.60
We know that Encik Halim bought 108 lemons, so we can write:
Total cost = Number of lemons bought x Cost per lemon
RM156.60 = 108x
Therefore, the cost per lemon bought by Encik Halim is:
x = RM156.60/108
x = RM1.45
So the price of each lemon bought by Encik Halim is RM1.45.

The expanded form of log y^10 is either 10 log y or 10 ln y
Expanding the logarithmAssuming that the base of the logarithm is not specified, we can use the change of base formula to expand the logarithm:
log y^10 = log (y^10) / log (base)
Since the base is not specified, we can use any base we like. For example, we can use base 10 or base e (natural logarithm).
Using base 10:
log y^10 = log (y^10) / log 10
= 10 log y / 1
= 10 log y
Using natural logarithm:
log y^10 = log (y^10) / log e
