Answer:

l = 2.25 cm

Step-by-step explanation:

given l is inversely proportional to w² then the equation relating them is

l = $\frac{k}{w^2}$ ← k is the constant of proportion

(i)

to find k use the condition w = 1.5 , l = 16 , then

16 = $\frac{k}{1.5^2}$ = $\frac{k}{2.25}$ ( multiply both sides by 2.25 )

36 = k

l = $\frac{36}{w^2}$ ← equation of proportion

(ii)

when w = 4 , then

l = $\frac{36}{4^2}$ = $\frac{36}{16}$ = 2.25 cm

Find a quadratic function with roots x = 7 and x = -1.

Charra [1.4K]

Answer:

x^2 - 6x - 7

Step-by-step explanation:

Roots, 7 and -1

x = 7 is the same as x - 7 = 0

x = -1 is the same as x + 1 = 0

multiply (x-7) by (x + 1)

x(x -7) +1(x - 7)

x^2 -7x + x - 7

x^2 - 6x - 7

Assuming that $3u + 12v\neq0$, simplify $\dfrac{12u^3 + 48u^2v}{3u+12v}$.

Kay [80]

Answer:

4u²

Step-by-step explanation:

$\dfrac{12u^3 + 48u^2v}{3u+12v}=\dfrac{12u^2(u+4v)}{3(u+4v)}=\boxed{4u^2}$

Common factors cancel from numerator and denominator. The one factor that might make the expression undefined is given as non-zero, so no additional restrictions apply.
