the rate from the plane to the radar station increasing 3 minutes later is 19.81 km/min
A plane flying with a constant speed of 14 km/min passes over a ground radar station at an altitude of 4 km and climbs at an angle of 45 degrees. At what rate is the distance from the plane to the radar station increasing one minutes later?
speed (Δs₁)= change in distance(Δd₁) /(Δt₁)change in time
mathematically,
(Δd₁) /(Δt₁) = Δs₁
= 14 km/min = (Δd₁) /(Δt₁)
and will are to find the speed after passes the radar
=Δs₂ km/min = (Δd₂) /(Δt₂)
to find distance d₁ and d₂ with respect to angle 45 degree at 4km
sin 45 = opp/hyp = 4/d₁
d₁ = 4/sin45 = 5.66km
tan 45 == opp/adj = 4/d₂
d₂ =4/tan45 = 4km
for one minute increment,
=1 x d₁ x Δs₁ = 1 x d₂ Δs₂

Given that cosA=1/4 where 270°
Angle A is located in the third quadrant and solved to be a value of 255.522 degrees.
What is quadrant?A quadrant refers to fourth division. In a circle, a quadrant represents a quarter of a circle.
In angle calculations, there are 4 quadrants. The first quadrant is between angles 0 to 90 degrees. The second quadrant is between angles 90 to 180 degrees. The third quadrant is between angles 180 to 270 degrees. The fourth quadrant is between 270 to 360 degrees.
The each quadrant is at 90 degrees interval. and the in angle calculations, the rotation is in anticlockwise direction
How to find angle Acos A = 1/4
where 270°
270 degrees represent the third quadrant. Hence angle A is in the third quadrant
solving for angle A
let cos a = 1/4
a = arc cos ( 1/4 )
a = 75.522 degrees ( in first quadrant )
A = a + 180 degrees
A = 75.522 degrees + 180 degrees
A = 255.522 degrees

The values of y varies directly with x. If x=8, when y=16. What is the value of y when x=16???
I need help asap
Answer:
y = 32
Step-by-step explanation:
With this problem, we will use the direct variation form, y = kx.
k = proportionality constant.
Substitute the known inputs of x = 8 and y = 16 into the direct variation form:
y = kx turns into 16 = k(8)
Get k by itself by dividing 8 on both sides:
16/8 = k
2 = k
Now that we know the k value is 2, we input everything we know into the direct variation form if x were equal to 16
k = 2
x = 16
y = kx:
y = 2(16), making y equal to 32

How to interpret Exponents?The exponent of a number tells us how many times to use the number in a multiplication. Exponents are also called Powers or Indices. For example in the exponent form ab^(x), we can say that;
The base is a and its' exponent is 1.
Applying the above to our question gives us;
If the exponent form is xy^3, then we can say that;

The percent of young men that are shorter than the mean height of young women is 2.5%.
What is a normal distribution?A data set with a normal distribution has the majority of its values clustered in the middle of the range and the remaining values tapering off symmetrically toward either end.
A continuous probability distribution for a real-valued random variable is known as a "normal distribution" in statistics.
Based on the information, the percentage will be calculated thus:
Z = (69.3 - 64) / 2.7 = 1.9630
So P(Z>1.96)= 1-P(Z<1.96)

Determine the bonus based upon the formula 2 weeks' salary plus 1 percent commission: annual salary: $48,000.00 yearly sales: $76,000.00
The bonus based upon the given formula is $2606.15 approximately
Given,
Annual salary = $48,000
Yearly sales = $76,000
Bonus is given according to the formula:
2 weeks salary + 1 percentage commission
Here,
Annual salary is given as $48,000
We have to find the weekly salary:
There is 52 weeks in a year.
So, salary for one week = Annual salary / number of weeks = 48000/52 = $923.077
Now, salary for two weeks = 923.077 × 2 = $1846.154
Rate of annual commission is 1%
The commission amount:
1% of yearly sales = 1% of 76000 = (1/100) × 76000 = $760
So,
The bonus amount = 2 weeks salary + 1 percentage commission
The bonus amount = 1846.154 + 760
The bonus amount = 2606.154
Therefore, the bonus given based upon the given formula is $2606.154

Mai wants to make an open-top box by cutting out the corners of a square piece of cardboard and folding up the sides. The cardboard is 10 centimeters by 10 centimeters. The volume () in cubic centimeters of the open-top box is a function of the side length in centimeters of the square cutouts.
Write an expression for ().
What is the volume of the box when =3?
The quantity of space inside a form is measured by its volume.
The volume as a function of side length(x) is: V(x) = 4x³ - 40x² + 100x
What is volume functions?
A three-dimensional space's volume can be calculated. It is frequently quantified numerically by different imperial units or SI-derived units. Volume and length have a mutually reliant relationship.
Given, length of the cardboard = 10 units
Width of the cardboard = 10 units
When side length(x) is removed from the cardboard, the dimension of the box becomes:
Length of the new cardboard = (10 - 2x) units
Width of the new cardboard = (10 - 2x) units
Height of the new cardboard = x units
Therefore, volume of the new cardboard box, V(x)
= Length*Width*Height
= x*(10 - 2x)*(10 - 2x) cubic units
= 100x² - 20x² - 20x² + 4x³
= 4x³ - 40x² + 100x

Step-by-step explanation:
1. For now, let's leave the [tex]g^{-6}[/tex] to the side and just worry about the [tex]\frac{h^8}{h^2}[/tex].
2. When you apply the exponent rule you should have learned in class, we know that when you divide two bases with exponents, the exponents subtract. So, you can subtract 8 - 2, and then the greater digit's place in the fraction stays. So, since [tex]h^8\\[/tex] is the greater number (and it's in the numerator), you put the [tex]h^6[/tex] in the numerator as well.
A boat is heading towards a lighthouse, whose beacon-light is 144 feet above the water. From point AA, the boat’s crew measures the angle of elevation to the beacon, 9^{\circ} ∘ , before they draw closer. They measure the angle of elevation a second time from point BB at some later time to be 14^{\circ} ∘ . Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.
Using the slope concept, the distance from point AA to point BB ≅ 360 feet.
What is a slope?The slope is given by the vertical change divided by the horizontal change.
It's also the tangent of the angle of depression.
We can get, the vertical change is of 144 feet.
At point A, the angle is of 9º, while the horizontal position is of [tex]x_{A}[/tex] ,
Then, we can write,
tan 9º = [tex]\frac{144}{x_{A} }[/tex]
[tex]x_{A}[/tex] = 144/tan 9º
Hence, tan 9º = 0.15
[tex]x_{A} =[/tex] 144/0.15
[tex]x_{A}[/tex] = 960
At point A, the angle is of 14º, while the horizontal position is of [tex]x_{B}[/tex] ,
Then, we can write,
[tex]x_{B}[/tex] = 144/tan 14º
Hence, tan 14º = 0.24
[tex]x_{B}[/tex] = 144/0.24
[tex]x_{B}[/tex] = 600
So, the distance in feet is of:
d = [tex]x_{A} -x_{B}[/tex]
d = 960 - 600
d = 360
d ≅ 360
Therefore,
A boat is heading towards a lighthouse, then the distance from point AA to point BB ≅ 360 feet.

Two angles are said to be complementary if the sum of the two angles is 90°
Here,
∠A = (2x + 5)°
∠B = (4x + 19)°
∠A and ∠B are complementary
