As the figure shows Elton runs 500 m to point b first then he turns 100 degrees and runs another 350 m to point c how far is the

Alex777 [14]

Answer:

658.24 m

Step-by-step explanation:

Let A be the point from where Elton started. Connect points A and C, you get triangle ABC with AB=500 m, BC=350 m and m∠B=100°. Use the cosine rule to determine the length of the segment AC:

$AC^2=AB^2+BC^2-2\cdot AB\cdot BC\cdot \cos \angle B,\\ \\AC^2=500^2+350^2-2\cdot 500\cdot 350\cdot \cos 100^{\circ},\\ \\AC^2=250000+122500-350000\cdot (-0.174),\\ \\AC^2\approx 433276.8622,\\ \\ AC\approx 658.24\ m.$

find the standard form of the equation of an ellipse that has a major axis of length 6 and fox at (-2,0) and (2,0)

Ksivusya [100]

Let the equation be $\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$
because the length of major axis is 6, 2a=6. then a=3, a²=9.
c=2, $a^2-b^2=c^2$ , so $b^2=5$
therefore, the equation is $\frac{x^2}9+\frac{y^2}5=1$

if right please mark me brainliest, thanks.
