Answer: A

Step-by-step explanation:

The first square is 22 inches on a side.

The second is 17.6 inches on a side

the third is 14.08 inches on a side.

We can suppose that we have a constant rate of decrease betwen the sides cubes, this means that:

22in*x = 17.6in

where x is the rate of scale.

x = 17.6/22 = 0.8

Now we test this with the second and third:

17.6in*0.8  = 14.08in

Ok, this works.

then the side of n-th cube can be found with the equation

L = 22*0.8^(n-1)

we can try the different options and see which one gives a value smaller than 10.

A) n = 5

L = 22*0.8^4 = 9.01

Then the correct option is A

What is the greatest common factor of the polynomial expression 2x^3 - 4x^2 + 6x?
iren2701 [21]

Step-by-step explanation:

2 {x}^{3}  - 4 {x}^{2}  + 6x \\  = 2x( {x}^{2}  - 2x + 3) \\  \because \: 2x \: is \: common \: from \: all \: terms \\  \therefore \: greatest \: common \: factor = 2x

A fish tank contains 14 goldfish 26 guppies. If you randomly select 2 fish what is the probility that they both are gold fish?
konstantin123 [22]
Probability=(number of favorable outcomes)/(number of total outcomes)
A=select the first gold fish.
P(A)=14/40
B=select the second gold fish
P(B)=13/39

A<span>∩B=select two fish gold

P(A</span><span>∩B)=P(A)*P(B)=(14/40)*(13/39)=182/1560=91/780

Given that a and b are the zeros of the polynomial f(x) = x^2 - x - 6 with a &gt; b, and that g(x) = f(x + 2) find:
artcher [175]

Answer:he end behavior of a function fff describes the behavior of its graph at the "ends" of the xxx-axis. Algebraically, end behavior is determined by the following two questions:

As x\rightarrow +\inftyx→+∞x, right arrow, plus, infinity, what does f(x)f(x)f, left parenthesis, x, right parenthesis approach?

As x\rightarrow -\inftyx→−∞x, right arrow, minus, infinity, what does f(x)f(x)f, left parenthesis, x, right parenthesis approach?

If this is new to you, we recommend that you check out our end behavior of polynomials article.

The zeros of a function fff correspond to the xxx-intercepts of its graph. If fff has a zero of odd multiplicity, its graph will cross the xxx-axis at that xxx value. If fff has a zero of even multiplicity, its graph will touch the xxx-axis at that point.

If this is new to you, we recommend that you check out our zeros of polynomials article.
