Step-by-step explanation:

I have enclosed a picture of the quadratic formula because I cannot seem to write the proper formula since it wont let me

✯Hello✯

↪  Alright so first we need to work out values for A B AND C

↪  We need to rearrange this since its the wrong way around

↪  A = -3

B= -10

C= 5

↪  we substitute these values and we get x=0.44 and x=-3.78

A submarine travels N45 W 16 miles. It then turns a course of 216 measured clockwise off of due north and travels until it is du
lozanna [386]

Answer:

19.5 miles

Step-by-step explanation:

The question is represented in the image attached.

∠A = 45°, ∠B = 45° + (216° - 180°) = 81°

∠A + ∠B + ∠C = 180° (sum of angles in a triangle)

45° + 81° + ∠C = 180°

126 + ∠C = 180

∠C = 180 - 126

∠C = 54°

The sine rule states that for a triangle with sides a, b, c and their corresponding opposite angles A, B and C. The following rule holds:

\frac{a}{sin(A)}= \frac{b}{sin(B)}= \frac{c}{sin(C)}

b = length of beginning of submarine to end point. Using sine rule:

\frac{b}{sin(81)} =\frac{16}{sin(54)} \\\\b=\frac{16}{sin(54)}*sin(81)\\\\b=19.5\ miles

What times 3 equals 20
e-lub [12.9K]
Your question can be reworded as
? X 3 = 20.

All you do is divide by 3 on both sides to isolate the x. It basically looks like a magician makes the 3 disappear and then appear on the other side.
\frac{?\times 3}{3} =  \frac{20}{3}
?= \frac{20}{3}

Tadah! We have mathmagically found the answer.

The answer is \boxed{ \frac{20}{3}}\boxed in fraction form or \boxed{6.66}\boxed in decimal form.
