One factor of the function f(x) = x3 − 8x2 + 17x − 10 is (x − 5). Describe how to find the x-intercepts and the y-intercept of t
kozerog [31]

Answer:

x-intercepts: (1,0), (2,0), (5,0)

y-intercepts: (0,-10)

Step-by-step explanation:

One factor of the function f(x) = x^3-8x^2 + 17x-10 is (x-5).

Factor the polynomial in the following way:

x^3-8x^2 + 17x-10\\ \\=x^3-5x^2-3x^2+15x+2x-10\\ \\=x^2(x-5)-3x(x-5)+2(x-5)\\ \\=(x-5)(x^2-3x+2)

Now factor the quadratic in brackets:

x^2-3x+2\\ \\=x^2-2x-x+2\\ \\=x(x-2)-(x-2)\\ \\=(x-2)(x-1)

Hence,

f(x)=(x-5)(x-2)(x-1)

The x-intercepts are points at which y = 0, so

(x-5)(x-2)(x-1)=0\\ \\x-5=0\ \text{or}\ x-2=0\ \text{or}\ x-1=0\\ \\x=5\ \text{or}\ x=2\ \text{or}\ x=1

The y-intercepts are points at which x = 0, so

y=0^3-8\cdot 0^2+17\cdot 0-10=-10

Explain how you can tell, without computing, whether the quotient of 1/2 divided by 6 is greater than 1 or less than 1.
Gnesinka [82]
You already know that the quetioent of 1/2 divided by 6 would be more or less than one because, 1/2 is equal to 50% and 50% of 6 is 3. So, you would know how the answer would turn out.

The exact value for the density of aluminum is 2.699g/cm3 . Working in the science lab at school , Joseph finds the density of a
Dennis_Churaev [7]
The formula for percent error is: (M-A)/A x 100
M= the amount of the sample measured
A= the exact value of the sample
And the value of M-A is always positive
So, 2.75-2.699= .051g/cm3, and .051/2.699=.01889
.01889 x 100=1.889% or 1.9% error

Match the two numbers with their least common multiple (LCM).
Vsevolod [243]

Answer:

8 and 4 = 8

8 and 10 = 40

Step-by-step explanation:

The least common multiple is the smallest value that both numbers equal when you look at their multiples.

The multiples of 8 are 8, 16, 24, 32, 40...

The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32...

The multiples of 10 are 10, 20, 30, 40...

The first multiple 8 and 4 have in common is 8.

The first multiple 8 and 10 have in common is 40.
