An isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14. The area of the trapezoid is

1 answer:

8 0

You forgot to add in your height to your question. To find your area you need to do 8 + 14 and get 22 then you nee to do the height divided by two. If you give me the height of the triangle I can tell you the area.

Answer:

Step-by-step explanation:

For equating the transaction fees of Lisa and the broker:

1.5 % of Total stock purchase price = $24

$\frac{1.5}{100} * x = 24$

∴Total Stock purchase price = $1600

It would be really helpful if anyone solved this for me !!!! It's differentiation.

Determine point A:

$y(x)=\frac{10}{2x+1}-2\\\frac{10}{2x+1}-2=0\implies x=2$

so A(2,0)

Find the function for the tangent:

$\frac{dy}{dx}=-\frac{-20}{(2x+1)^2}$

the tangent function is a line

$y=ax + b = \frac{dy}{dx}|_A\cdot x + b\\$

(with slope being the derivative evaluated at point A(2,0))

$\frac{dy}{dx}|_A=-\frac{4}{5}$ so a=-4/5.

Determine b by using what we know about A:

$y=-\frac{4}{5}x+b\\0=-\frac{4}{5}\cdot 2+b\implies b=\frac{8}{5}$

so the function is

$y = -\frac{4}{5}x+\frac{8}{5}\\5y + 4x = 8$

(i) this is demonstrated above

(ii) distance AC: we know A(2,0) and C(0,5/8), the distance is:

$\sqrt{(0-2)^2+(\frac{5}{8}-0)^2}=\sqrt{281}/8\approx 2.1$
