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:

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

Evaluate expression -16 squared and write the result in form a + bi

coldgirl [10]

Writing it in the form of a+bi we get 0+4i

Step-by-step explanation:

We need to evaluate expression -16 squared and write the result in form a+bi

The given expression is: $\sqrt{-16}$

We know that $\sqrt{-1}=i$

We know that 16= 4x4 = 4^2

Putting values:

$\sqrt{-16}=\sqrt{-1}\sqrt{16}\\=\sqrt{4^2}i\\=4i$

So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i

(5у — 4)°<br> Зу<br> (2x + 13)°

ale4655 [162]

Answer:

No Solution.

Step-by-step explanation:

Equality equation:

— 2y – Зу +8 = 8 — 5у – 12 (Given)

-5y + 8 = -4 - 5y (distributive property of equality)

-5y = -12 - 5y (subtraction property of equality)

= -12 (addition property of equality)

when you add 5y on both sides it cancels the 5y out, it's no solution.
