Mathematics
1 answer:
Karolina [17]3 years ago
7 0

Answer:

Step-by-step explanation:

x^{5} -x^{4}-2x^{3}  +2x^{2} =0\\\\x^{4} (x-1) -2x^{2} (x-1) =0\\\\(x^{4} -2x^{2} ) (x-1)=0\\\\ x^{2} (x^{2} -2)(x-1) =0

solutions are

x² =0 so x=0

x²-2 = 0 so x= ±√2

x-1 =0 so x= 1

krok68 [10]

Answer:

a = 73.84, b = -23.64, c = 83.97, d = 21.73

Step-by-step explanation:

1880:

The predicted value is:

f(80) = 1.363\cdot (80) - 35.2

f(80) = 73.84

The residual value is:

\Delta f = 50.2 - 73.84

\Delta f = -23.64

1920:

The predicted value is:

f(120) = 7.8 \cdot 1.02^{120}

f(120) = 83.97

The residual value is:

\Delta f = 105.7 - 83.97

\Delta f = 21.73

( Will hand out brainiest) A California condor left its cliff-side nest and soared downwards at a rate of 16 meters per second.
svet-max [94.6K]

First calculate the distance covered going down:

d_down = (16 m / s) * 8 s = 128 m

 

Then the distance going up is:

d_up = 71 m

 

So the distance from the ledge to the nest is:

d = 128 m – 71 m = 57 m

 

Therefore the elevation is:

<span>elevation = 1364 m + 57 m = 1421 m</span>
