Answer:

see explanation

Step-by-step explanation:

Given

\sqrt{\frac{4x^2}{3y} }

= \frac{\sqrt{4x^2} }{\sqrt{3y} }

= \frac{2x}{\sqrt{3y} }

Rationalise the denominator by multiplying the numerator/ denominator by \sqrt{3y}

Note that \sqrt{a} × \sqrt{a} = a

= \frac{2x}{\sqrt{3y} } × \frac{\sqrt{3y} }{\sqrt{3y} }

= \frac{2x\sqrt{3y} }{3y}

A line includes the points (8,5) and (9, – 5). What is its equation in point-slope form?
zmey [24]

Answer:

Step-by-step explanation:

slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

         =\frac{-5-5}{9-8}\\\\=\frac{-10}{1}\\\\=-10\\

Point-slope form:

y - y1 = m(x - x1)

y - 5 = -10(x - 8)

Lydia invested $5900 in an account paying an interest rate of 2 5/8% compounded monthly. Jace invested $5900 in an account payin
Alexus [3.1K]

Answer:

$875.18

Step-by-step explanation:

Given data

Lydia

P=$5900

Interest rate=2 5/8% >>21/8= 2.625%

compounded monthly.

First, convert R percent to r a decimal

r = R/100

r = 2.625%/100

r = 0.02625 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 5,900.00(1 + 0.0021875/12)^(12)(19)

A = $ 9,710.01

Jace

P=$5900

Interest rate= 2 1/8% >>> 17/8>> 2.125%

Time= 19 years

First, convert R percent to r a decimal

r = R/100

r = 2.125%/100

r = 0.02125 per year,

Then, solve our equation for A

A = Pert

A = 5,900.00(2.71828)^(0.02125)(19)

A = $ 8,834.83

Hence the difference in their account balance is

= 9,710.01- 8,834.83

=$875.18

Therefore Lydia has $875.18 more money than Jace

Use the formula P = 2l + 2w. Find the perimeter of a rectangle with a length of 12.9 ft and a width of 19.3 ft.
Black_prince [1.1K]
Welp, it can't get any easier. Now, they give you the value for l (length which is 12.9) and the give you the value for w (width which is 19.3)

Now, you'd just plug them in. So

P = 2(12.9) + 2(19.3)
  =25.8+38.6
   =64.4ft
