<h2>Time Interval : 1 sec to 1.414 sec</h2>
Step-by-step explanation:
The height of the stuntperson jumping off a
is modelled as
. Here
is the time in seconds.
We have to record the person when he is between the heights
from the ground.
When
,

When
,

The stuntperson is at height
at
, and is at height
at
.
∴ The camera should film the person for the time interval
.
Answer:

Step-by-step explanation:
The given function is

We need to find all real zeros of the given function.
Equate y=0, to find all real zeros of the given function.

Subtract 1 from both sides.


Divide both sides by 3.


Therefore, the real zero of the function is -1/3.
Answer:
f1: 0.440, f2: 0.931, f3: 1.519
Step-by-step explanation:
To solve the system of equations we need to use the inverse of matrix A, as follows:
A x F = C
A^-1 x A x F = A^-1 x C
I x F = A^-1 x C
where I is the identity matrix.
The inverse of A is:
1.450 -0.392 -0.090
A^-1 = -0.074 -0.022 0.1536
-0.406 0.7122 -0.060
(computed with Excel)
The multiplication between the inverse of A and C gives:
0.440
A^-1 x C = 0.931
1.519
(computed with Excel)
Step-by-step explanation:
1. 3x+y+17=0
2.x-y+3=0
