Which of the following is a factor of 2x^4 22x^3 60x^2? 2x^3 x^4 x 4 x 5

zavuch27 [327]

The factor theorem says that for a function f(x), if f(a) = 0, then (x - a) is a factor of f(x).
For f(x) = 2x^4 + 22x^3 + 60x^2
f(-5) = 2(-5)^4 + 22(-5)^3 + 60(-5)^2 = 2(625) + 22(-125) + 60(25) = 1250 - 2750 + 1500 = 0
Therefore, x - (-5) = x + 5 is a factor of f(x).

Provide an example of a function that does not have an inverse function. How do you prove that it is not a function?

SOVA2 [1]

Answer:

f(x) = x^2 is a classic example

f( 3 ) = 9 and

f( -3 ) = 9, but

f^(-1)[9] is undefined because the result can be 3 and -3

Solar-heat installations successfully reduce the utility bill 60% of the time. What is the probability that at least 9 out of 10

AnnZ [28]

Answer:

P=0.04635.

Step-by-step explanation:

We know that solar-heat installations successfully reduce the utility bill 60% of the time. We calculate the probability that at least 9 out of 10 solar-heat installations are successful and will reduce the utility bill.

We know that: 60%=0.6=p and n=10.

We have a binomial distribution: X : (10, 0.6).

We use the formula to calculate the probability:

$\boxed{ P(X=x)=\left( \begin{array}{c} n \\ x \end{array} \right) \cdot p^x \cdot (1-p)^{n-x}}$

We get:

$P(X\geq 9)=1-P(X$

Therefore, the probability is P=0.04635.
