2. (a＋b)²＝a²＋2ab＋b²
(5x－2)²＝(5x)²－2×5x×2＋2²
(5x－2)²＝25x²－20x＋4

4. (a＋b)²＝a²＋2ab＋b²
(2x＋5)²＝(2x)²＋2×2x×5＋5²
(2x＋5)²＝4x²＋20x＋25
∵a＝4, b＝20, c＝25
∴a＋b＋c＝4＋20＋25＝49

Hope my answer helped u :)

$x^3$ is strictly increasing on [0, 5], so

$\max\{x^3 \mid 0\le x\le5\} = 5^3 = 125$

and

$\min\{x^3 \mid 0 \le x\le5\} = 0^3 = 0$

so the integral is bounded between

$\displaystyle \boxed{0} \le \int_0^5x^3\,dx \le \boxed{125}$

Ethan is watching a satellite launch from an observation spot 1 mile away. Find the angle of elevation from Ethan to the satelli

Thepotemich [5.8K]

Answer:

$\theta=80.53^{\circ}$

Step-by-step explanation:

From the attached figure, AB is the height of the satellite and the distance between Ethan and the ground is 1 mile.

We can find the angle of elevation from Ethan to the satellite using trigonometry as follows :

$\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{6}{1}\\\\\theta=\tan^{-1}(6)\\\\\theta=80.53^{\circ}$

So, the angle of elevation is 80.53 degrees.
