Furkat [3]

Answer: $\frac{\sqrt[4]{10xy^3}}{2y}$

where y is positive.

The 2y in the denominator is not inside the fourth root

==================================================

Work Shown:

$\sqrt[4]{\frac{5x}{8y}}\\\\\\\sqrt[4]{\frac{5x*2y^3}{8y*2y^3}}\ \ \text{.... multiply top and bottom by } 2y^3\\\\\\\sqrt[4]{\frac{10xy^3}{16y^4}}\\\\\\\frac{\sqrt[4]{10xy^3}}{\sqrt[4]{16y^4}} \ \ \text{ ... break up the fourth root}\\\\\\\frac{\sqrt[4]{10xy^3}}{\sqrt[4]{(2y)^4}} \ \ \text{ ... rewrite } 16y^4 \text{ as } (2y)^4\\\\\\\frac{\sqrt[4]{10xy^3}}{2y} \ \ \text{... where y is positive}\\\\\\$

The idea is to get something of the form $a^4$ in the denominator. In this case, $a = 2y$

To be able to reach the $16y^4$ , your teacher gave the hint to multiply top and bottom by $2y^3$

For more examples, search out "rationalizing the denominator".

Keep in mind that $\sqrt[4]{(2y)^4} = 2y$ only works if y isn't negative.

If y could be negative, then we'd have to say $\sqrt[4]{(2y)^4} = |2y|$ . The absolute value bars ensure the result is never negative.

Furthermore, to avoid dividing by zero, we can't have y = 0. So all of this works as long as y > 0.

F(t) = -(t-2) (t-15)

Goryan [66]

Answer:

smaller (t) = 2 and this in coordinates form (2,0)

larger (t) = 15 and this in coordinates form (15,0)

the vertex of the parabola = $(\frac{17}{2} ,\frac{169}{4} )$ or in decimals (8.5, 42.25)

Step-by-step explanation:

For the zeros of the function take each bracket and make it equal to zero.

SMALLER (t):

(t-2)=0

(add 2 for both sides)

t=2

LARGER (t):

(t-15)=0

(add 15 for both sides)

t=15

For the vertex of the parabola you do:

step1: expand the brackets:

f(t)=-(t-2)(t-15)

f(t)= $-t^{2} +17t-30$

step2: define a,b and c using the expression $ax^{2} +bx+c$ :

a= -1 (the coefficient of $t^{2}$ )

b= 17 (the coefficient of t)

c= -30 (the single number without a letter)

step3: sub the values in the formula $-\frac{b}{2a}$ to find the x coordinate of the vertex :

$-\frac{b}{2a}$

= $- \frac{17}{2*-1}$

= $\frac{17}{2}$ or in decimals 8.5

step4: sub the value of t (the x-coordinate) in equation f(t):

f(t)= $-t^{2} +17t-30$

f ( $\frac{17}{2}$ ) = - $(\frac{17}{2} )^{2}$ + 17× $\frac{17}{2}$ - 30

= $-\frac{289}{4}$ + $\frac{289}{2}$ -30

= $\frac{169}{4}$ or in decimals 42.25
