Answer:

Option B.

Step-by-step explanation:

The given expression is

\dfrac{x^2+y^3}{2+x}

We need to find the value of given expression when x=6 and y=2.

Substitute x=6 and y=2 in the given expression.

\dfrac{x^2+y^3}{2+x}=\dfrac{(6)^2+(2)^3}{2+(6)}

                   =\dfrac{36+8}{8}

                   =\dfrac{44}{8}

                   =5.5

The value of given expression is 5.5 when x=6 and y=2.

Therefore, the correct option is B.

Step One

Find the area of the base

A = s * s

s = 755.5 feet

Area = 755.5^2

Area = 570780.25 square feet.


Step two

Multiply the volume by 3

V = 1/3 B * h

3*V = B * h

V = 85600000

85600000 * 3 = B * h

256800000 = B * h


Step Three

Divide by B

B = 570780.25


256800000 = 570780.25 * h

256800000 / 570780.25 = h

449.91 feet = h

The lenght of a turtles shell z, in millimeters, is related to the turtles age in years a , as described by the equation below.
puteri [66]

Answer:

B, C , F

Step-by-step explanation:

The age multiplied 55, so the shell grows at rate of 55mm per year

in fact if the age is 2 we have (55 x 2) = 55 + 55

if 3 = (55 x 3) = 55 + 55 + 55

and so on

When the turtle is hatched the shell is 37 mm in lenght.

In fact, if we substitute 0 to a, we have

s = (55 x 0) + 37

s = 37

when the turtle is 1 year old, the shell is 92 mm in length.

in fact if we substitu a with 1, we have

s = (55 x 1) + 37

s = 55 + 37

s = 92

Help me with this please.<br>​
Flura [38]

Answer:

B

Step-by-step explanation:

Points A,B ,C are all to the left of 0 so they are negative

We want a point -3 1/2

The points A and B are to the left of -3 so they are more negative than -3

A is at -5 so it cannot be -3 1/2
