Suppose a plane is flying at an altitude of 32,200 feet two minutes after the start of its descent. Ten minutes after the start

of its descent, the plane is at an altitude of 16,200 feet.
Use the given information to construct a linear function that represents the altitude of the plane at any given time during its descent. What is the altitude of the plane at 12 minutes?

Write a mathematical argument that can be used to defend your solution.

Tell whether the ordered pair is a solution of the linear system (-24,-10)
Dovator [93]

Answer:

IT is not

Step-by-step explanation:

Let's replace. If it's a solution, it means that BOTH equations has to be true.

\left \{ {{-10=-5(-24)+22} \atop {-2(-24) +6(-10)=-12} \right.

Now, the second equations seems good - 48-60 =-12 indeed.

First alas isn't. RHS is 142, which is totally not the same as -10.

A rectangular sheet of metal has an area of 112 square inches. Its perimeter is 44 inches. What are the dimensions of the sheet?
sveticcg [70]
A) w * L = 112
B) 2w + 2L = 44
A) w = 112 / L then substituting this into B)
B) 2 * (112/L) + 2L = 44
B) 224 / L + 2L = 44
B) 224 + 2L^2 = 44L
B) 2L^2 -44L +224 = 0
L = 14
L = 8

Double Check
Width = 14  Length = 8
2*14= 28 2*8 = 16
28 + 16 = 44

14*8= 112
Correct!!!

What does it mean to use the cosine value of an inverse of tan θ?
Bond [772]

Answer:

\boxed{  \begin{array}{ccc} \displaystyle  \theta =  {120}^{ \circ}   \\      \displaystyle\sin( {120}^{ \circ} )  =  \frac{ \sqrt{3} }{2}  \end{array}}

Step-by-step explanation:

we are given a inverse trig

we want to figure out the value of \theta

in that case we can consider using unit circle in unit circle the value of arctan (-√3)=120°

therefore,

the value of theta is 120°

likewise by unit circle the value of sine is

\displaystyle   \sin( {120}^{ \circ} )  =  \frac{ \sqrt{3} }{2}
