It is a polynomial or not write step in step

galben [10]

Answer:

√(3x)-2y+7

here √(3x) means, √3×√x

√x = x^(1/2)

now, now the exponent is 1/2, which means it's not a polynomial

4. Lisa walked 48 blocks in 3 hours.<br> blocks per hour

dlinn [17]

Answer:

The number of blocks in one hour is the same that the unit rate, so 16 blocks per hour

Step-by-step explanation:

we know that

To find out the unit rate, divide the total blocks by the total time

so

$\frac{48}{3}\ \frac{blocks}{hours}=16\ \frac{blocks}{hour}$

Can anyone tell me what this graph is in slope intercept form?

Eddi Din [679]

Answer:

the standard form equation is 1/2x^2-x-3/2=0

the vertex form equation is 1/2(x-1)^2-2=0

Step-by-step explanation:

Unfortunately, this can't be written in slope intercept form but I can write it in standard form(ax^2+bx+c) or vertex form (a(x-h)+k)

The vertex is (1,-2)

I estimate a=1/2 because the graph was widened and that can only be done by a fraction.

So, 1/2(x-1)^2-2=0

To find it in standard form

foil (x-1)(x-1)= x^2-2x+1

Then multiply by 1/2(x^2-2x+1)= 1/2x^2-x+1/2-2

To add 1/2-2. You mulitply -2 by 2/2 which equals 1/2-4/2 which equals -3/2

So the standard form equation is 1/2x^2-x-3/2=0

The remains of an ancient ball court include a rectangular playing alley with a perimeter of about 18m. The length of the alley

mariarad [96]

Given:

Perimeter = 18 m

The formula for the perimeter of a rectangle is:

$P=2l+2w$

Where:

l = lenght

w = width

In this case, we have that:

l = 2w

Therefore, we substitute the values in the formula:

$\begin{gathered} P=2l+2w \\ 18=2(2w)+2w \end{gathered}$

And solve for w:

$\begin{gathered} 18=4w+2w \\ 18=6w \\ \frac{18}{6}=\frac{6w}{6} \\ w=3 \end{gathered}$

For the length:

$l=2w=2(3)=6$

Answer:

The width is 3 m

The length is 6 m
