Use slopes and y-intercepts to determine if the lines y=−x2+14 and 3x−4y=−1 are parallel.
Keith_Richards [23]
Answer: the lines are not parallel.


Explanation: if you isolate the x in 3x^2-4y=-1, the equation is y=3/4x^2+1/4


So, they are not parallel because the slope is not the same.

Tangent line i think please help me find x
Alex

Answer:

x= 6.5 cm

Step-by-step explanation:

When a tangent line touches the circle, it forms a right angle triangle at that point

Apply the Pythagorean relationship in this case

Given that the height is = 20.2 cm = b

The hypotenuse is = c= x+14.7 cm

General formulae is;

a² +b² =c²

x² + 20.2² =( x+ 14.7)²

x² + 408.04= x² +14.7x+14.7x+216.09

x² + 408.04= x² + 29.4 x +216.09.........................collect like terms

x²-x² + 408.04-216.09= 29.4x

191.95= 29.4x-------------------------------divide by 29.4 t0 get x

191.95/29.4 =x

x=6.5 cm
