Hello : 
<span>a point on the y-axis is : P( 0, y)
</span>PA = PB  or  PA² = PB².... A(7, -7)    B(1,1)
(7-0)²+(-7-y)² = (1-0)² + (1-y)²
49+49+14y+y² = 1+1-2y+y²
16y = - 96
y= - 6

How do you translate the graph of f(x) = x3 left 4 units and down 2 units? Identify the equation of the graph
Marina CMI [18]

Answer:

The correct option is B.

Step-by-step explanation:

The given function is

f(x)=x^3

The translation of a function is defined as

g(x)=f(x+a)+b

If a>0, then the graph of f(x) shift a units left and if a<0, then the graph of f(x) shift a units right.

If b>0, then the graph of f(x) shift b units up and if b<0, then the graph of f(x) shift b units down.

It is given that the graph of f(x) shifts 4 units left and 2 units down.  So, a=4 and b=-2.

g(x)=f(x+4)+(-2)

g(x)=(x+4)^3-2              [\because f(x)=x^3]

y=(x+4)^3-2

Therefore option B is correct.

Hom many 1/4 ft fish food boxes could fit in a 3 3/4 ft box
IrinaK [193]

Answer : There are 13 fish food bags are could fit in a box of size 3\frac{1}{4} ft.

Explanation :

Length of box = 3\frac{3}{4} ft

Length of fish food box = \frac{1}{4} ft

Number of fish food boxes could fit in a box = \frac{\text{length of a box}}{\text{length of fish food box}}

Number of fish food boxes could fit in a box  =\frac{3\frac{1}{4}}{\frac{1}{4}}\\=\frac{\frac{13}{4}}{\frac{1}{4}}\\= \frac{13}{1}

Hence, there are 13 fish food bags are could fit in a box of size 3\frac{1}{4} ft.
