What is 28 1/2 of 120
sveta [45]

Answer:

3,420

Step-by-step explanation:

\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 28\frac{1}{2}\\\\\mathrm{Convert\:element\:to\:fraction}:\quad \:120=\frac{120}{1}\\=\frac{57}{2}\cdot \frac{120}{1}

\mathrm{Cross-cancel\:common\:factor:}\:2\\=\frac{57}{1}\cdot \frac{60}{1}

\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}\\=\frac{57\cdot \:60}{1\cdot \:1}

\mathrm{Multiply\:the\:numbers:}\:57\cdot \:60=3420\\=\frac{3420}{1\cdot \:1}\\ \\\mathrm{Apply\:rule}\:\frac{a}{1}=a\\3420

Hope this helps you!

Answer: y= (x+2)(x-2)

X- intercept(s): Set y to 0 and solve  (   0=x^{2}+4  ,      4=x^{2} ,       \sqrt{4} =x, x=  2, -2)

Answers: x=  2, -2

Y- intercept: Set x to 0 and solve (   y= 0^{2}+4,         y=0+4,         y=4)

Answer: y=4

Nina graphs the function y = ⌊x⌋ to learn the properties of the parent floor function. What is the value of y when x =5.7?
Nikolay [14]

Answer:

5

Step-by-step explanation:

When you given input of "x" into a floor function  y = ⌊x⌋ , it gives as output the "greatest integer less than or equal to x"

For example, if we were to given 1.4 as the input for floor function, it will return the greatest integer that is less than or equal to 1.4, so it would be 1.

<u>So, if we put 5.7 into this function, the floor function would give "5" as the output.</u>

<u>Thus value of y would be 5</u>
