Answer:

320 x13/30 = 138.66

Step-by-step explanation:

We need to solve 320 X 13/30

Multiply 320 with 13

320 x 13 / 30

= 4160 / 30

= 138.66

So, 320 x13/30 = 138.66

As the limit of x goes to 3 from the left find the limit of (x/ sqrt x^2 -9)
Dimas [21]
\displaystyle\lim_{x\to3^-}\frac x{\sqrt{x^2-9}}=\lim_{x\to3^-}\frac x{\sqrt{x^2}\sqrt{1-\frac9{x^2}}}=\lim_{x\to3^-}\frac x{|x|\sqrt{1-\frac9{x^2}}}

Since x>0, you have |x|=x and the limand reduces to

\displaystyle\lim_{x\to3^-}\frac1{\sqrt{1-\frac9{x^2}}}

For x>3, you have \sqrt{1-\frac9{x^2}}>0 since \dfrac9{x^2} will always be smaller than 1, which means \dfrac1{\sqrt{1-\frac9{x^2}}}\to+\infty

What’s the answer to this
KonstantinChe [14]

Answer:

C

Step-by-step explanation:

  • (a+b)² = a² + 2ab  + b²
  • example : (5+2)² = 5² + 2.5.2 + 2²  = 49

9x² + 6x + 1

9x²  = (3x)²

1 = 1²

6x = 2.3x.1

So => 9x² + 6x + 1 => <em>(3x + 1)² </em>

Hope this helps ^-^

Write an equation of the perpendicular bisector of the segment with the endpoints (3,5) and (9,−1). HELP!!!!!
nalin [4]

The equation of the perpendicular bisector of the segment with the endpoints (3,5) and (9,−1) is y = x + 8

<h3>Equation of a line</h3>

The equation of a line in slope intercept form is expressed as;

y = mx + b

The equation of the perpendicular bisector will be given as y = -1/m x+ b

where

m is the slope

b is the y-intercept

Determine the slope

Slope = -1-5/9-3

Slope = -6/6

Slope = -1

For the y-intercept

-1 = -1(9) + b

-1 = -9 + b

b = 8

Determine the equation

y = -1/m x + b

y = -1/(-1) x + 8

y = x + 8

Hence the equation of the perpendicular bisector of the segment with the endpoints (3,5) and (9,−1) is y = x + 8
