Let f(x)=x+1 and g(x)= x^2 – 2. Find f (x)· g(x)

gogolik [260]

Answer:

f(x)·g(x) = x³ +x² -2x -2

Step-by-step explanation:

Substitute the function definitions and simplify.

f(x)·g(x)

= (x +1)(x² -2)

= x(x² -2) +1(x² -2)

= x³ -2x +x² -2

f(x)·g(x) = x³ +x² -2x -2

Two trains are moving towards each other on parallel tracks, both going at a constant rate of 60km/h. A passenger sitting in one

wariber [46]

Answer:

200 m

Step-by-step explanation:

$v = 60 km/h \times\frac{1000m}{1km}\times\frac{1h}{3600sec}}=\frac{60}{3.6}m/s$

For the passenger, the other train moves at a rate of 2v

Time t = 6 sec

The length = (2v) x t = $2\times\frac{60}{3.6}\times 6=200 m$

Amy reached into a bag, recorded the color of the tile she picked, returned the tile and drew again. These are the tiles she has

Vedmedyk [2.9K]

Answer:

(a) P(next ball with blue) = $\frac{3}{10}$ (b) P(Not to be red) = $1-\frac{2}{5} =\frac{3}{5}$

(c) P(drawing 70 times yellow ball) = $\frac{1}{10} \times 70 = 7$ .

Step-by-step explanation:

Given that,

The total outcomes of the color of tile are :-

Red , Red, Blue, Yellow, Blue, Red, Green, Red, Blue, Green.

From the Question,

Total number of outcomes = 10

(a) What is the probability that her next draw will be blue ?

Red = 4,

Blue = 3,

Green = 2,

Yellow = 1.

P(next ball with blue) = $\frac{3}{10}$ .

(b) What is the probability that her next draw will NOT be red?

P(Red ball) = $\frac{4}{10} = \frac{2}{5}$

But we have to find

P(Not to be red) = $1-\frac{2}{5} =\frac{3}{5}$

(c) If Amy draws 70 more times with the same tiles from the question above, what probability would you expect a yellow?

P(Yellow ball) = $\frac{1}{10}$

drawing it 70 times we get the probability

P(drawing 70 times yellow ball) = $\frac{1}{10} \times 70 = 7$ .
