Answer:

Step-by-step explanation:

2x(x^{2} + 3)

when x = 0 then we have a y intercept

2x^{3} +6x

so b/c both terms have an x  in them

we know the only time this function hits the y intercept is when y is zero

got it?

answer y = 0

Tim,Griff and Kay baked chocolate for Kay s birthday party.Tim baked 3 times as many as Kay.Griff baked half as many as Tim.Alto
lianna [129]
Answer: 48

------------------------------------------------------------------------------
Define the number of cakes they baked in term of x
------------------------------------------------------------------------------
Let the number of cakes Kay baked be x

Kay = x
Tim = 3x                ← Tim baked 3 times as many as Kay
Griff = 1.5x            ← Griff baked 1/2 as many as Tim

------------------------------------------------------------------------------
Construct the equation and solve for x
------------------------------------------------------------------------------
The total number of cakes baked was 88.

x + 3x + 1.5x = 88        ← Combine like terms
5.5 x = 88                     ← Divide by 5.5
÷5.5    ÷5.5
x = 16

------------------------------------------------------------------------------
Find the number of cakes each baked
------------------------------------------------------------------------------
Kay = x = 16
TIm = 3x = 16 x 3 = 48
Griff = 1.5x = 1.5(16) = 24

------------------------------------------------------------------------------
Answer: Tim baked 48 cakes.

What is the surface area to volume ratio of a 5 cm cube?
joja [24]
Answer: 6/5

Explanation:
Given: 5cm cube
This means each side is 5 cm because a cube has equal sides.

Area of a square is length times width so area of 1 side of a cube:
= 5 x 5
= 25

Surface area is the area of one side of a cube times the number of sides. Now, how many sides does a cube have? 6
= 25 x 6
= 150

Surface area of a 5cm cube = 150

Volume is length times width times height:
= 5 x 5 x 5
= 125

Ratio of surface area to volume:
= 150/125
= 6/5
