Oli has a volume of 9000cm3 and a density of 0.8g/cm3

gogolik [260]

We know, mass = Density * Volume
mass = 9000 * 0.8 g
mass = 7200 g = 7.2 Kg

So, you final answer is 7.2 Kg

Hope this helps!

Suppose that F(x) = x2 and G(x) = -1/4(x+7)^2 . Which statement best compares the graph of G(x) with the graph of F(x)?

vaieri [72.5K]

F(x) = x^2

G(x) = -1/4 (x+7)^2

7 is added to x , so graph shifts left by 7 units

multiplied by negative , so reflected over x axis

and multiplied by 1/4 so vertical compression by a factor of 1/4

So graph of g(x) is shifted left by 7 units , reflected over x axis and compressed vertically by a factor of 1/4

Which sequence could be described by the explicit definition: a n = n 2 − 5

kirza4 [7]

The sequence represented by given explicit definition is:

-4,-1,4,11,20,....

Step-by-step explanation:

We will find the terms of the sequence to find the right sequence for given explicit definition

Given explicit formula is:

$a_n=n^2-5$

We will put n=1,2,3,4,5...... in the formula

So,

Putting n=1

$a_1=(1)^2-5\\=1-5\\=-4$

Putting n=2

$a_2=(2)^2-5\\=4-5\\=-1$

Putting n=3

$a_3=(3)^2-5\\=9-5\\=4$

Putting n=4

$a_4=(4)^2-5\\=16-5\\=11$

so, comparing the values with given options we can conclude that

The sequence represented by given explicit definition is:

-4,-1,4,11,20,....
