lim x→π/2 1-sinx/cot^2x
any genious help please
Rewrite the limand as
(1 - sin(x)) / cot²(x) = (1 - sin(x)) / (cos²(x) / sin²(x))
… = ((1 - sin(x)) sin²(x)) / cos²(x)
Recall the Pythagorean identity,
sin²(x) + cos²(x) = 1
Then
(1 - sin(x)) / cot²(x) = ((1 - sin(x)) sin²(x)) / (1 - sin²(x))
Factorize the denominator; it's a difference of squares, so
1 - sin²(x) = (1 - sin(x)) (1 + sin(x))
Cancel the common factor of 1 - sin(x) in the numerator and denominator:
(1 - sin(x)) / cot²(x) = sin²(x) / (1 + sin(x))
Now the limand is continuous at x = π/2, so
[tex]\displaystyle\lim_{x\to\frac\pi2}\frac{1-\sin(x)}{\cot^2(x)}=\lim_{x\to\frac\pi2}\frac{\sin^2(x)}{1+\sin(x)}=\frac{\sin^2\left(\frac\pi2\right)}{1+\sin\left(\frac\pi2\right)}=\boxed{\frac12}[/tex]

Answer: 1-14' 1" is prob. your width
Step-by-step explanation:
i can’t find out length Sorry.
Step-by-step explanation:
Scale : 4 in = 5ft.
1 in. = 5/4 = 1.25 ft
Actual length = 25 x 1.25 = 31.25 ft.
Actual width = 16 x 1.25 = 20 ft
Actual area = actual length x actual width
= 31.25 x 20
= 625 ft²
Ramps in a parking garage need to be safe and steep. The maximum safe incline for a ramp at 8.5°. Is this ramp safe? Explain how you know using your math to justify your answer.
NEED ASAP PLEASE
Answer:
No. It is not safe.
Step-by-step explanation:
If the maximum safe incline for a ramp is said to be 8.5°, it means that the incline of any ramp that is greater than 8.5° is not safe.
Let's find the angle measure of the incline in the diagram given to ascertain whether it is safe or not.
Opposite side to angle of inclination = 20
Adjacent side to angle of inclination = 100
Apply the trigonometric function, TOA, which is:
Tan θ = Opp/Adjacent
Tan θ = 20/100
Tan θ = 0.2
θ = Tan^{-1}(0.2)
θ = 11.3099325° ≈ 11.3°
Angle of inclination for the ramp shown = 11.3°.
This is not safe because it has exceeded the maximum safe incline for a ramp which should be 8.5° maximum.
A man is 6 feet tall. At 1:00, he casts a shadow that is 18 inches long. A nearby tree is 32 feel tall. At the same time of day, how long is the tree's shadow?
The answer of this would be 8 feet long.
If you take 6 feet and put that into inches, the man would be 72 inches tall. at one oclock he casts a shadow that is 1/4 of his length. so if we take this knowledge to the tree and divide 32 feet by 4, we get 8 feet long
answer: 8 feet

What is the area of a circular region whose
diameter is 12 centimeters?
Answer:
A circle of radius = 12 or diameter = 24 or circumference = 75.4 cm has an area of: 4.524 × 10-8 square kilometers (km²)
The area of the circular region will be 113 square centimeters.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
The formula to calculate the area of the circle is given by:-
A = πr²
Given that the diameter of the circular region is 12 centimeters. The radius will be half of the diameter.
r = d / 2
r = 12 / 2 = 6
The area of the region will be calculated as below:-
A = πr²
A = π x ( 6 ) x ( 6 )
A = 113.09 square centimeters
Therefore, the area of the circular region will be 113 square centimeters.

One year ago today the temperature was 3 degrees colder. Five years ago today the temperature was 15 degrees warmer. Select the inequalities that correctly express the relationship between the temperature one year ago today and five years ago today with respect to today's temperature.
Therefore , the solution of the given problem of inequality comes out to be x + 15 < x - 3 and x - 3 > x + 15
An inequality is what?In mathematics, a connection or group of integers can be an inequality without the equal sign. Equilibrium is always followed by equity. Inequality occurs when norms are still incompatible. Disparity and fairness have distinct traits. We chose to use the most typical symbol because components aren't always equivalent or similar to one another (). Any disparity, no matter how small or large, can also be used to evaluate values.
Here,
Let x represent the weather today.
The difference between today's temperature and last year's is three degrees, so last year's temperature was x - 3.
Since the weather was 15 degrees higher five years ago, the previous temperature was x + 15.
We can use the following language to describe the relationship between the temperature today and one year ago today but instead five years ago today with respect to the current temperature:
=> x + 15 < x - 3 (five years ago temperature is less least 1 year ago temperature)
=> x - 3 > x + 15 (one year ago temperature is bigger than five years ago temperature)
Therefore, the proper disparities are:
=> x + 15 < x - 3
=>x - 3 > x + 15
