Answer:

the Pythagorean theorem states:

a^2 + b^2 = c^2

in your case a=14 and b=48

Step-by-step explanation:

14^2 + 48^2 = c^2

14x14 + 48x48 = c^2

(196 + 2304 = 2500)

2500 = c^2

√2500 = c

50 = c

Final answer: 50

Answer:

Step-by-step explanation:

let 2x be the length of chord tangent to first circle.

so x=√(14²-6²)=√(14+6)(14-6)=√(20×8)=√160=4√10

length of chord=2x=2×4√10=8√10

ZanzabumX [31]

Answer:

y = $\frac{2}{3}$ x+ $\frac{13}{3}$

Step-by-step explanation:

Okay, the first thing to do here is calculate something known as the "slope".

We know two points are ( 1 , 5 ) and ( − 2 , 3 )

The slope is represented by "m" in the standard form: y = mx+b

The slope is also known as the rise over the run, y2-y1/x2-x1 = $\frac{3-5}{-2-1}$ = $\frac{2}{3}$

=> the standard form: y = $\frac{2}{3}$ x+b

Now we have to use the slope, and resubstitute another point to get b

5 = $\frac{2}{3}$ (1) + b

<=> b= 5- $\frac{2}{3}$ = $\frac{13}{3}$

So the equation that model the line is: y = $\frac{2}{3}$ x+ $\frac{13}{3}$
