Given that f(x) = x2 + 5x – 14 and g(x) = x + 7, find (fºg)(x) and express

mel-nik [20]

Answer:

We get $\mathbf{(fog)(x)=x^3+12x^2+21x-98}$

Step-by-step explanation:

We are given:

$f(x) = x^2 + 5x - 14 \\ g(x) = x + 7$

We need to find $(f o g)(x)$

We know that: $(fog)(x)=f(x)\times g(x)$

We multiply the both terms i.e. f(x) and g(x) to get our answer.

$(fog)(x)\\=f(x)\times g(x)\\=(x^2+5x-14)(x+7)\\=(x^2+5x-14)(x)+(x^2+5x-14)(7)\\=x^3+5x^2-14x+7x^2+35x-98\\Combining\:like\:terms:\\=x^3+5x^2+7x^2-14x+35x-105\\=x^3+12x^2+21x-98$

So, we get $\mathbf{(fog)(x)=x^3+12x^2+21x-98}$

For the month of March in a certain city, 57% of the days are cloudy. Also in the month of March in the same city, 55% of th

kirill115 [55]

Answer:

P(F | C) = 0.96

Step-by-step explanation:

Hi!

This is a problem on conditional probability. Lets call:

C = { cloudy day }

F = { foggy day }

Then F ∩ C = { cloudy and foggy day }

You are asked for P(F | C), the probability of a day being foggy given it is cloudy. By definition:

$P(F|C)=\frac{P(F\bigcap C)}{P(C)}$

And the data you have is:

$P(C) = 0.57\\P(F \bigcap C) =0.55$

Then: P(F | C) = 0.96
