The general form for this is y^2 = 4ax where a = focus
the directrix is same distabce behind the vertex as focus is in font so focus a = 4
so we have y^2 = 16 x
or
x = (1/16) y^2
Its C
For scientific notation, you always want 1 digits in front of the decimal.
Ex) 7.39*10^5
Move the decimal point in between the 1 and 4, or 1 place to the left.
1.435
Since the decimal point was moved 1 place to the left, the exponent after 10 will be 1.
1.435*10^1
1.435*10^1 is your final answer.
1.435*10 is the same thing also.
Answer:
The area is 19.63.
Step-by-step explanation:
Answer:
90°
Step-by-step explanation:
Circle C has radius √36 = 6
Circle D has radius √18 = 3√2
As the D radius intersecting either point of tangency, does so at a right angle.
The half angle θ between the tangents is
sinθ = 3√2 / 6 = ½√2
θ = 45°
so the angle between the tangents is 2(45) = 90°
Answer:
la respuesta a ambos es 1 porque si elevas cualquier numero a un exponente de 0 este queda en 1
