Without doing the math, determine which is greater, 40. 1/4 or 40÷ 1/4. Explain your reasoning.

maw [93]

40 ÷ $\frac{1}{4}$ is greater

multiplying a whole number by a fraction reduces the size of the whole number

dividing a whole number by a fraction increases the size of the number

X^2 + 4y^2 =100; 4y - x^2 = -20

deff fn [24]

$x^2+4y^2=100\implies x^2=100-4y^2$
$\implies 4y-(100-4y^2)=-20$
$\implies 4y^2+4y-80=0$
$\implies y^2+y-20=0$
$\implies (y-4)(y+5)=0$
$\implies y=4,y=-5$

When $y=4$ , you have

$4(4)-x^2=-20\implies x^2=36\implies x=\pm6$

When $y=-5$ ,

$4(-5)-x^2=-20\implies x^2=0\implies x=0$

So there are three solutions, $(x,y)\in\{(6,4),(-6,4),(0,-5)\}$ .

H=(...-2,-10,1,2,...3what type of set is H

e-lub [12.9K]

Answer: Universal set

Step-by-step explanation:

A universal set is usually represented by U and it is set that has all the elements of a related sets.

For example, if there are two sets which are X and Y. Let's say X = {1,2,3} and Y = {1,a,b,c}, therefore, the universal set will be U = {1,2,3,a,b,c}.

In the above scenario, H(...-2,-10,1,2,...3) is a Universal set.

Simplify: (picture)<br> and please show how you got to the answer, thanks!

Troyanec [42]

$(16 a^{3} b^{4} )^ \frac{3}{4}$

Expand,

$16^{ \frac{3}{4} } a^{3* \frac{3}{4} } b^{4* \frac{3}{4 } }$
= $8 a^{ \frac{9}{4} } b^{3}$

So the third choice would be your answer!

Hope this helps!
