an airplane is flying at the height of 10 km above the ground the distance along the ground from the airplane to the airport is 10√3 km . what is the angle of depression from the airplane to the ground
Answers
The angle of depression from the aeroplane to the ground will be 30 degrees.
What is trigonometry?
Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.
Given that:-
An aeroplane is flying at the height of 10 km above the ground the distance along the ground from the aeroplane to the airport is 10√3 kmThe angle of depression will be calculated as the angle between the horizontal and the height of the plane as shown in the figure below.
As we know that the perpendicular theta is height and the base ratio is angle tan theta.
tanФ = Height / Base
tanФ = 10 / 10 √3
tanФ = 1 / √3
Ф = tan⁻¹( 1 / √3 ) = 30°
Therefore the angle of depression from the aeroplane to the ground will be 30 degrees.

AB is a directed segment with endpoints A(2,2) and B(14,14). In two or more complete sentences, explain how you would verify that Point X, with a coordinate of (6,6), divides in AB a 1:2 ratio?
Answers
Answer:
See below ~
Step-by-step explanation:
Applying section formula :
⇒ x = 1(14) + 2(2) / 1 + 2 = 18/3 = 6
⇒ y = 1(14) + 2(2) / 1 + 2 = 18/3 = 6
We understand after substituting the values of the endpoints in the section formula that the Point X divides the line in the ratio 1 : 2.

Answers
It makes that every time we flip a fair the probability of flipping tails is 50%.
What is the probability?Probability determines the chances that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0. If it is equally likely and unlikely that the event would happen, it would have a probability of 0.5
Probability of flipping tails = number of tails / number of sides

Which rational function has zeros at x = -1 and x = 6 ?
Answers
Answer:
[tex]f(x) = \frac{x^{2} -5x-6}{x^{2} -4}[/tex]
Step-by-step explanation:
Let's factorize the 1st option :
⇒ [tex]f(x) = \frac{x^{2} -5x-6}{x^{2} -4}[/tex]
⇒ [tex]f(x) = \frac{x^{2}+x-6x-6 }{(x+2)(x-2)}[/tex]
⇒ [tex]f(x) = \frac{(x+1)(x-6)}{(x+2)(x-2)}[/tex]
===============================================================
Finding the zeros :
⇒ Factors of numerator should be equated to 0
x + 1 = 0 ⇒ x = -1x - 6 = 0 ⇒ x = 6=============================================================
Solution :
[tex]f(x) = \frac{x^{2} -5x-6}{x^{2} -4}[/tex]
Answer:
first option
Step-by-step explanation:
the zeros are determined by the numerator of the rational function.
given that the zeros are x = - 1 and x = 6 , then the corresponding factors are
(x + 1) and (x - 6) , that is
(x + 1)(x - 6) ← expand using FOIL
= x² - 5x - 6
the rational function is then
f(x) = [tex]\frac{x^2-5x-6}{x^2-4}[/tex]

2. tossing 1 blue and 1 pink
3. not tossing all pink
outcome | frecuency
2 blue | 1
2 pink | 3
1 blue, 1 pink | 6
Answers
Answer:
1. 30%, 2. 60%, 3. 70%Step-by-step explanation:
According to table the total frequencies is:
1 + 3 + 6 = 10Probability = Favorable outcome frequency / total frequency
Find each probability according to equation above:
1. P(2 pink) = 3/10 = 30%2. P(blue and pink) = 6/10 = 60%3. P(not all pink) = (10 - 3)/10 = 7/10 = 70%The experimental probability of the event are: 3/10; 3/5; 7/10.
Experimental probabilityFrequencies=1 + 3 + 6
Frequencies = 10
Hence:
Tossing 2 pink:
P(2 P) = 3/10
P(2 P) =30%
Tossing 1 blue and 1 pink:
P(B and P) = 6/10
P(B and P)=60% or 3/5
Not tossing all pink:
P(not all P) = (10 - 3)/10
P(not all P)= 7/10
P(not all P)=70%
Therefore the experimental probability of the event are: 3/10; 3/5; 7/10.

A square on a coordinate plane is translated 9 units down and 1 unit to the right.
Let's (x, y) be the coordinate.
where x be the horizontal move and y be the vertical move.
As, it is translated 9 units down and 1 unit right.

OA. Yes, because it passes the vertical line test.
OB. Yes, because it is a curved line.
OC. No, because it is not a straight line.
OD. No, because it fails the vertical line test.
Answers
This graph represents a function Because it passes the vertical line test.
Let us first understand the Vertical Line Test.
In this test, we draw a few random vertical lines on a graph and check whether any one or more than one lines intersect the graph, no matter once or more.
If there exists a line that intersects the graph, we say the graph passes the vertical line test.
What is the vertical line test?
The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.
Hence this graph passes the vertical line test because there are many vertical lines that intersect it.

Step-by-step explanation:
a^m * a^n = a^(m+n)
so, 6^a * 6^v = 6^a+v
Answer:
[tex] {6}^{a+v} [/tex]
Step-by-step explanation:
We want to find the value of
[tex]{6}^{a} \times 6 ^{v} [/tex]
We can do so by using basic exponent laws.
Multiplying exponents with the same base law:
(note that the base is the number under the exponent, in this case both bases have a value of 6 so we use this law)
[tex]a ^{m} \times {a}^{n} = {a}^{m+n} [/tex]
Explanation of law : We simply keep the bases the same and add the exponents.
Applying this law to 6^a * 6^v
We acquire
6^a * 6^v
==> keep the bases the same and add the exponents
