Answer:
first jet is steeper; not unreasonable
Step-by-step explanation:
The slopes in feet per mile for the two jets are ...
(26,400 ft)/(96 mi) = 275 ft/mi
(31,680 ft)/(120 mi) = 264 ft/mi
The descent of the first jet is steeper.
__
The path a jet will follow depends on a number of factors, including weather and other air traffic. It is not unreasonable for a jet to follow a linear glide path to an airport from these altitudes and distances. JFK is sufficiently busy that air traffic control may dictate other-than-linear descent paths.
Final approach is typically done on a 3° glide slope, about 277 ft descent per mile.
_____
Additional comment
Studies have been done to test the feasibility of linear descent paths into some of the busiest airports in the world. The conclusion is that fuel burn could be improved and air traffic management made simpler by such flight paths. However, current jet autopilots are not equipped for direct input of such flight routes. Pilot workload would be slightly increased until software could be updated. There appears to be no current plan to change the way terminal area control is done.
Is 16t - 3t equivalent 3t - 16t
Answer:
No, 16t -3t equals 13t while 3t - 16t equals -13t
Answer:
No,
16t= 16x2=32
3t=3x2=6
32-6=26
3t=3x2=6

What is the average rate of change of the function f(x) = 4x – 2 over the interval x = –1 and x = 2?
Answer:
[tex]4[/tex]
Step-by-step explanation:
Given: [tex]f(x)=4x-2[/tex]
To find: average rate of change of the function [tex]f(x)=4x-2[/tex] over the interval [tex]x=-1[/tex] and [tex]x=2[/tex]
Solution:
Take [tex]a=-1,\,b=2[/tex]
Find [tex]f(a),\,f(b)[/tex]
[tex]f(a)=f(-1)\\=4(-1)-2\\=-4-2\\=-6\\\\f(b)=f(2)\\=4(2)-2\\=8-2\\=6[/tex]
Average rate of change of the function [tex]=\frac{f(b)-f(a)}{b-a}[/tex]
[tex]=\frac{f(2)-f(-1)}{2-(-1)}\\\\=\frac{6-(-6)}{3} \\\\=\frac{12}{3}\\\\=4[/tex]

Step-by-step explanation:
Hisako sells dolls at her doll store. If she sells a doll for $35, and there is 6% sales tax, what is the tax amount a customer will pay on one doll?
Given:
The price of a doll = $35
Sales tax = 6%
To find:
The tax amount that a customer will pay on one doll.
Solution:
The price of doll is $35 and the sales tax is 6%, so the tax amount on a doll is 6% of 35.
[tex]\text{Tax amount}=35\times \dfrac{6}{100}[/tex]
[tex]\text{Tax amount}=\dfrac{210}{100}[/tex]
[tex]\text{Tax amount}=\dfrac{21}{10}[/tex]
[tex]\text{Tax amount}=2.1[/tex]
Therefore, the tax amount that a customer will pay on one doll is $2.1.

Jasmine has twice as much money as Madison. Madison has $6 less than Devanie. Together they have $54. How much money does Madison have?
Answer:
madision be $12
Jasmine be $24
And, the devanie be $18
Step-by-step explanation:
The computation is shown below:
Madison be x
Jasmine be 2x
Devanie be x + 6
And, the total is $54
Now the equation is
x + 2x + x + 6 = $54
4x = $48
x = $12
So madision be $12
Jasmine be $24
And, the devanie be $18

The sum of interior angles of a regular polygon is 24 times the size of exterior angle. Find number of sides of the polygon
Answer:
n = 50
Step-by-step explanation:
The sum of interior angles of a regular polygon is 24 times the size of exterior angle. Find number of sides of the polygon
let the sum of exterior be e
Let the sum of interior be i
IF the sum of interior angles of a regular polygon is 24 times the size of exterior angle, then;
i = 24e
Also sum of exterior angle = 360/n
i + e = 180
24e + e = 180
25e = 180
e = 180/25
e = 7.2
since sum of exterior angle = 360/n
7.2 = 360/n
n = 360/7.2
n = 50
The number of sides is 50

9. The volume of a triangular prism is 30 cm. Each triangular face has an area of 4 cm. How long is the prism?
Answer:
12
Step-by-step explanation:
The required length of the triangular prism is given as 15 centimeters.
Given that,
The volume of a triangular prism is 30 cm. Each triangular face has an area of 4 cm, how long the prism is to be determined.
Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Here,
The volume of the triangular prism = 1 / 2[area of face] × length
30 = 1/2 [4] × length
length = 15 cm
Thus, the required length of the triangular prism is given as 15 centimeters.

$11,988
Step-by-step explanation:
A graphing calculator gives you the answer easily.
The minimum unit cost is $11,988.
__
The equation for unit cost can be put into vertex form to find the minimum.
C(x) = 0.7x^2 -210x +27738
C(x) = 0.7(x^2 -300x +150^2) +27738 -0.7(150^2)
C(x) = 0.7(x -150)^2 -11,988
This is vertex form:
C(x) = a(x -h)^2 +k . . . . . . . where (h, k) is the vertex.
The vertex of this cost function is (150, 11,988).
The minimum unit cost occurs when 150 engines are produced. That unit cost is $11,988.
Answer:
the answer is $11,988
