Draw the vector C⃗ =A⃗ +2B⃗ . The drawing is attached below
<h3>Further explanation </h3>Vector is a quantity that has a value and direction. It can be symbolized in the form of directed line segments. Operations on vectors include addition and subtraction.
In the drawing, vector B seems to be (1, 108 degrees) and vector A seems to be (4, 0 degrees) in the drawing.
Where If vector is added by inverse
then the sum becomes
If we multiply vector A by 1 then the length becomes 1 times vector A and in the same direction, so does vector B multiplied by the value of +2, which is 2 times the length of vector B in the same the direction as vector A, so we get vector C (attached picture) obtained by drawing a line from the starting point A and the endpoint B

Answer:
use the pythagorean theorem:
Answer:
y = x² - 7
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (0, - 7), thus
y = a(x - 0)² - 7
To find a substitute (4, - 3) into the equation
- 3 = a(4 - 0)² - 7, that is
- 3 = 16a - 7 ( add 7 to both sides )
4 = 16a ( divide both sides by 16 )
a = , thus
y = x² - 7
