you are 5 feet tall. if the angle of elevation of a tower is 23 degree and you are standing 10 feet away from the base of the tower, how tall is the tower?
The height of the tower is 9.24 feet. That is, the tower is 9.24 feet tall
Calculating the height of a towerFrom the question, we are to determine how tall the tower is
From the given information,
From a distance of 10 feet, the angle of elevation of the tower at a height 5 feet from the ground is 23 degrees.
Let x represent the length of the tower from a point 5 feet from the ground.
Thus,
The height of the tower will 5 + x feet
Now, we will determine x
Using SOH CAH TOA
tan 23° = x / 10
x = 10 × tan 23°
x = 4.24 feet
Height of the tower is 5 + x feet
Therefore,
Height of the tower = 5 + 4.24 feet
= 9.24 feet
Hence,
The height is 9.24 feet

Step-by-step explanation:
they are parabolas.
their line of symmetry is exactly in the middle between their x-intercepts (when y = 0).
these x-intercepts we get from the factors : y can only be 0, when at least one of the factors is 0.
y = (x + 14)(x + 16)
means y = 0, when x = -14 or x = -16.
so, the line of symmetry is
x = -15
y = (x - 12)(x - 18)
y = 0, when x = 12 or x = 18
line of symmetry is
x = 15
y = (x + 13)(x - 17)
x = -13 or x = 17
line of symmetry
x = 2 (again, the middle between -13 and +17)
y = (x - 10)(x + 20)
x = 10 or x = -20

What are the domain and range of a function?
The domain is the set of all x-values that can be used to make the function "work" and produce actual y-values.
A function's range is the variety of conceivable y-values (minimum y-value to maximum y-value)
Find domain:
Set the denominator equal to zero and solve for x.
x+2=0
x=-2
This means, domain is set of all real numbers except x=2.
Set builder notation: { x ∈ R | x ≠ -2 }. R= real numbers
Find range:
Replace f(x) by y in the given equation and solve for x.

Add the proper constant to the binomial so that the resulting trinomial is a perfect square. Then factor the trinomial.
n-18n+
We need to add 81 as the constant term to the binomial (n² - 18n) so that the resulting trinomial is a perfect square, and factorization of that resulting trinomial will be (n - 9).
As per the question statement, we are provided with a binomial (n² - 18n),
And we are required to add a proper constant to the above mentioned binomial so that the resulting trinomial is a perfect square, and then factorise the resulting trinomial.
To answer question, first we need to know the standard form of expanding a perfect square into a trinomial, which goes as,
[(a - b)² = {(a)² + (b)² - (2 * a * b)]
Here, if we compare our concerned binomial (n² - 18n), or, [(n)² - (2 * n * 9)], with the above mentioned standard expansion of a perfect square into a trinomial, we get, (a = n) and (b = 9), and the (b²) term is missing.
Adding [(b²) = (9²) = 81] which is a constant term, to our concerned binomial (n² - 18n), we get, (n² - 18n + 81),
Or, [(n)² + (9)² + (2 * n * 9)],
Which is a trinomial and matches with the standard expansion of a perfect square into a trinomial, and hence,
[(n² - 18n + 81) = (n - 9)²]
That is, we need to add 81 as the constant term to the binomial (n² - 18n) so that the resulting trinomial is a perfect square, and factorization of that resulting trinomial will be (n - 9).

Answer:
X=30
Step-by-step explanation:
[tex](4x + 30) + (2x - 30) = 180 \\ 4x + 2x + 30 - 30 = 180 \\ 6x = 180 \\ x = 30[/tex]
Answer:
x = 30
Step-by-step explanation:
We are told that:
• m∠A = (4x + 30)°
• m∠B = (2x - 30)°,
and that these two angles are supplementary to each other.
When two angles are supplementary to each other, it means that they add up to 180°.
Therefore:
∠A + ∠B = 180°
⇒ (4x + 30)° + (2x - 30)° = 180°
⇒ 4x + 30 + 2x - 30 = 180
⇒ 4x + 2x + 30 - 30 = 180 [Combining like terms]
⇒ 6x = 180
⇒ [tex]\frac{6}{6}x = \frac{180}{6}[/tex] [Dividing both sides of the equation by 6]

Og(-1)=-3
O g(-1)=0
O g(-1)=1
O g(-1)=27
The function g(-1) has its value to be (c) g(-1) = 1
How to evaluate the function at the input value?The definition of the function is given as
g(x)=x³+6x² + 12x+8
Rewrite the above function properly
So, we have the following representation
g(x) = x³ + 6x² + 12x + 8
To find the function g(-1), we set the value of x in the equation g(x) = x³ + 6x² + 12x + 8 to -1
This is represented by
Calculate g(x), when x = -1
Substitute -1 for x in the equation g(x) = x³ + 6x² + 12x + 8
So, we have the following equation
g(-1) = (-1)³ + 6(-1)² + 12(-1) + 8
Evaluate the exponents
This gives
g(-1) = -1 + 6(1) + 12(-1) + 8
Evaluate the products
This gives
g(-1) = -1 + 6 - 12 + 8
Evaluate the sum
g(-1) = 1
Hence, the value of the function is g(-1) = 1
