Solve the following inequality: 3-5x-x^2>=0

Dennis_Churaev [7]

Answer:

-5/2+-1/2√37≤x≤-5/2+1/2√37

Step-by-step explanation:

Step 1: Find the critical points

-x^2-5x+3=0

For this equation: a=-1, b=-5, c=3

−1x^2+−5x+3=0

x=−b±√b2−4ac/2a

x=−(−5)±√(−5)2−4(−1)(3)/2(-1)

x=5±√37 /−2

x=-5/2+1/2√37

Step 2: Check intervals in between critical points

x≤-5/2+1/2 √37 (Doesn't work in original inequality)

-5/2+-1/2√37≤x≤-5/2+1/2√37 (Works in original inequality)

x≥-5/2+1/2 √37 (Doesn't work in original inequality)

Can you write the equation for a circle if the given point does not lie on the circle? Explain .

Pachacha [2.7K]

Answer:

Step-by-step explanation:

The equation of a circle with center (a,b) and radius r is given as:

${(x - a)}^{2} + {(y - b)}^{2} = {r}^{2}$

If a given point (x,y) does not lie on this circle, it will not satisfy its equation.

This means the distance from the point to the center is not equal to the radius.

It is either less or greater than the radius.

Hence you cannot write the equation of the circle.

Suppose the inside bottom of a box is painted with three colors: one-third of the bottom area is blue, one-sixth is red, and one

miss Akunina [59]

Answer:

The probability that the pebble will NOT land on color blue is 0.67.

Step-by-step explanation:

We attribute the box area as the probability of the events.

So the probability of landing in the Red Area is 1/6, the probability of landing in the Blue Area is 1/3 and the probability of landing in the Yellow Area is 1/2.

P(Red)= $\frac{1}{6}$

P(Yellow)= $\frac{1}{2}$

P(Blue)= $\frac{1}{3}$

The probability of landing in NOT Blue area is given by:

P(Not Blue)=1-P(Blue)= $1-\frac{1}{3}=\frac{2}{3} =0.67$
