Answer:
Obj B, by 1 g/cm^3
Step-by-step explanation:
Obj A = 12g / 8cm^3 = 3g / 2cm^3 = 1.5 g/cm^3
Obj B = 20g / 8cm^3 = 5g / 2cm^3 = 2.5 g/cm^3
2.5 - 1.5 = 1 g/cm^3
Answer:
11
Step-by-step explanation:
The surface area of the cube with a side length of 2 units is 24 units squared
<h3>How to determine the surface area?</h3>
The side length of the cube is given as:
l = 2
The surface area is calculated as:
Surface area = 6l^2
This gives
Surface area = 6 *2^2
Evaluate
Surface area = 24
Hence, the surface area of the cube is 24 unit squared

To find the zeros of this function, we must first set the entire function equal to 0
f(x) = x² - 2x - 15 = 0
Since this is a quadratic function, we must use the quadratic formula, which is:

Let's assign a, b, and c using our first function
x² means a = 1 (because it could be written as 1x²)
-2x means b = -2
-15 means c = -15
Now let's plug those in:

which simplifies to:

Simplified further:


And divide it by the 2 on the bottom gives us:

2+4 = 6
2-4 = -2
So the zeros of this function are
-2 and
6
