A tablecloth has a length of
bearhunter [10]

Answer:

45/64 m²

Step-by-step explanation:

We are given the length and width of the tablecloth (breath = width).

  • Length = 9/8 m
  • Width = 5/8 m

We know that the formula for the area of a rectangle is A = L × W.

Assuming the tablecloth is in the shape of a rectangle (since the problem gives us length and width), we can substitute the length and width into the formula.

  • A = 9/8 × 5/8
  • A = 45/64

The area of the tablecloth is 45/64 m².

Find the equation of the tangent of x^2- xy + y^2 =7 at (-1, 2)
Citrus2011 [14]

Answer:

<u>It</u><u> </u><u>is</u><u> </u><u>3</u><u>y</u><u> </u><u>=</u><u> </u><u>4</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u><u>0</u>

Step-by-step explanation:

Let's first get the slope of the curve.

[ slope is the derivative of the equation ]

{x}^{2}  - xy +  {y}^{2}  = 7

introduce dy/dx :

\frac{d}{dx} ( {x}^{2}  - xy +  {y}^{2} ) =  \frac{d}{dx} (7) \\  \\ 2x - (y +  \frac{dy}{dx} ) + 2y \frac{dy}{dx}  = 0

make dy/dx the subject:

2x - y -  \frac{dy}{dx}  + 2y \frac{dy}{dx}  = 0 \\  \\ 2y \frac{dy}{dx}  -  \frac{dy}{dx}  = y - 2x \\  \\  \frac{dy}{dx} (2y - 1) = y - 2x \\  \\  \frac{dy}{dx}  =  \frac{y - 2x}{2y - 1}

At point (-1, 2):

\frac{dy}{dx}  =  \frac{2 - 2( - 1)}{2(2) - 1}  \\  \\ slope =  \frac{4}{3}

but a tangent has the same slope as the curve:

y = mx + c

m is the slope

c is the y-intercept

At (-1, 2):

2 = ( - 1 \times  \frac{4}{3} ) + c \\  \\ c = 2 +  \frac{4}{3}  \\  \\ c =  \frac{10}{3}

equation:

y =  \frac{4}{3} x +  \frac{10}{3}  \\  \\ { \boxed{3y = 4x + 10}}

2=(1+r/100n)^nt
klasskru [66]

Answer:

a) Log ( 2 ) = 4t Log ( 83/80 )

b) 4.7 years

Step-by-step explanation:

Attached below is the detailed solution

<u>a) exponential statement in log form for an investment at 15% quarterly </u>

Log ( 2 ) = 4t Log ( 83/80 )

n = 4 ,  r = 15

<u>b) using change to base  to find double time in yr </u>

Double time in yr

t = Log ( 2 ) / 4log ( 83/80 )

= 4.7 years
