A plane flies at an altitude of 3.5 kilometers and then starts to descend when it is 60
kilometers from the runway. What is the angle of depression for the descent of the plane?
Round to the nearest degree.
Answer:
Angle of depression = 3.37°
Step-by-step explanation:
We are told that A plane flies at an altitude of 3.5 kilometers and then starts to descend when it is 60
kilometers from the runway.
I've attached an image of a triangle depicting this question.
From the triangle, we can find the angle of depression θ from trigonometric ratio since it's a right angle triangle.
Thus;
3.5/60 = tan θ
tan θ = 0.0583
θ = tan^(-1) 0.0583
θ = 3.37°

Answer:
40, 80, 120
Step-by-step explanation:
0, 40, 80, 120, 160, 200
+40
Answer:
0, 40, 80, 120, 160, 200
Step-by-step explanation:
The numbers are decreasing by 40. 200-160=40. Therefore, we need to subtract 40 each time from every number we get.
160-40=120
120-40=80
80-40=40
Now, plug the numbers into the sequence. It should now look like this:
0, 40, 80, 120, 160, 200

If m varies directly as v² and m =3, when v=2, calculate the value of m when v=9
Answer:
m=243/4 when v=9.
Step-by-step explanation:
We know that when y varies directly with x², the formula of direct proportion is
y=kx²where 'k' is the constant of variation.
so
As m varies directly with v², and m=3 when v=2
m=kv²
k=m/v²
= 3/(2)²
=3/4
Hence, k=3/4
so when v=9 then the expression becomes
m=kv²
substituting v=9 and k=3/4
m= 3/4(9)²
=3/4 × 81
=243/4
Therefore, m=243/4 when v=9.
2b-m=5 what is the solution for m
Answer:

The area of a circle is 25pie in.2. What is it’s radius?
The area of a circle is PI x r^2
25PI = PI x r^2
Divide both sides by PI:
25 = r^2
Take the square root of both sides:
Radius = 5 inches.
Answer:
5 is the radius.
Step-by-step explanation:
Since the formula for area in a circle is [tex]\pi r^{2}[/tex], we can substitute 25 for r squared.
Since 25 is equal to r squared, it means that r is equal to 5.
5 is the radius.

f/13 = 6.2 what is the value of f
Answer:
The value of f is 80.6.
Step-by-step explanation:
We are given the equation and asked to solve for f.
If we are given a fraction with a variable in the numerator, we can multiply both sides of the equation by the denominator to isolate it.
For example, if you look at this equation:
[tex]\displaystyle\frac{a}{26}=17.9[/tex]
We can multiply both sides by 26 to get the a by itself so the equation can be solved.
[tex]\displaystyle26\times\frac{a}{26}=17.9\times26\\\\a = 465.4[/tex]
Therefore, we can apply this same technique to the equation [tex]\frac{f}{13}=6.2.[/tex]
[tex]\displaystyle\frac{f}{13}=6.2\\\\13\times\frac{f}{13}=6.2\times13\\\\f = 80.6\ \text{or} \ \frac{403}{5}[/tex]
Therefore, the value of f is 80.6.
Answer:
f = 80.6
Step-by-step explanation:
Multiply both sides by 13.
f /13 =6.2
( f /13 )*(13)=(6.2)*(13)
f = 80.6

Eight bags of chips and four sodas cost $5. Four bags of chips and eight sodas costs
$7. How much does a bag of chips cost? How much does a soda cost?
Answer:
let x be chips and y be sodas
8x + 4y = 5 ---> for the first hint
4x + 8y = 7------> second hint
0.25 cents is how much chips costs
and 0.75 cents is how much sodas costs
Answer: Each bag of chips is $0.25, each soda is $0.75.
(0.25 x 8) + (0.75 x 4) = 5
2 + 3 = 5
(0.25 x 4) + (0.75 x 8) = 7
1 + 6 = 7
What is the sum of the rational expression below? 3x/x+2 + x/x+4

B. 4x/2x + 6
C. 3x^2/x^2 + 8
D. 4x^2 + 4x +8/x^2 + 6x +8
The sum of the rational expression is (4x²+14x)/ (x²+6x+8)
How to find the sum of the rational expression?
A rational expression is an expression that is the ratio of two polynomials. For example, the expression (x^2 + 2x + 1) / (x + 1) is a rational expression. The numerator and denominator can have different degrees and the expression can be simplified if there is a common factor.
To find the sum of the rational expression 3x/(x+2) + x/(x+4). First, find the LCM of (x+2) and (x+4), which is (x+2)(x+4):
3x/(x+2) + x/(x+4) = [3x(x+4) + x(x+2)] / (x+2)(x+4)
= [3x²+12x + x²+2x] / (x²+4x+2x+8)
= (4x²+14x)/ (x²+6x+8)

What is Proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Here the given three points are (0, 0), (5, 3), (10, 6).
So, equation of the line passing through the points (0, 0), (5, 3) is
y- 0/ (x-0)= (3-0)/(5-0)
y/ x = 3/5
y= 3/5x

∠A and \angle B∠B are vertical angles. If m\angle A=(3x+26)^{\circ}∠A=(3x+26) ∘ and m\angle B=(x+20)^{\circ}∠B=(x+20) ∘ , then find the value of x.
Answer:
The value of x is -3
Step-by-step explanation:
The vertical angles are equal in measures∵ ∠A and ∠B are vertical angles
→ By using the rule above
∴ m∠A = m∠B
∵ m∠A = (3x + 26)°
∵ m∠B = (x + 20)°
→ Equate their measures
∴ 3x + 26 = x + 20
→ Subtract x from both sides
∵ 3x - x + 26 = x - x + 20
∴ 2x + 26 = 20
→ Subtract 26 from both sides
∵ 2x + 26 - 26 = 20 - 26
∴ 2x = -6
→ Divide both sides by 2
∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{-6}{2}[/tex]
∴ x = -3
∴ The value of x is -3

Answer:
The length of each side of the base must be 6.
Step-by-step explanation:
Total volume = 396
Volume = Length x width x height
We know height = 11
So,
11 x Length x Width = 396
396 / 11 = 36
Length x Width = 36
This is a square prism so all sides of base are equal.
Length = 6
Width = 6
And therefore all the other sides of the base are also 6.
