Explain how the value of the discriminant B^2-4AC can be used to predict the number of solutions an equation has?

Alexxandr [17]

We need to know this:

If Δ > 0 we have two and different solutions

If Δ = 0 we just one solution

If Δ < 0 we don't have real solutions

The functions f(x) and g(x) are shown on the graph.<br> f(x) = |x|<br> What is g(x)?

ICE Princess25 [194]

Answer

Answer is B i think or A

so whoever below me or infront of me picks is probably the right one but its probably gonna be B

"if we use,,y=2x,,,this is well defined, on a x-y coordinate plane, y rises twice as fast as x moves to right. . g(x) =2x or h(x) =2x,,,,,mean the same thing,,,except the axis is now g(x),,or h(x)." - online resource front page

Simply its y,x except g is y or wtvr but it has more meaning

A and B together can do a work in 6 days. If A alone can do it in 15 days. In how many days can B alone do it.

Answer:

10 days to complete

Step-by-step explanation:

for mixed rate problems, the sum of each individual reciprocal rates equals the sum of the combined rate

i.e

$\frac{1}{A's rate} + \frac{1}{B's Rate} = \frac{1}{combined rate}$

we are given,

A's rate = 15 days to complete

Combined rate = 6 days to complete

B's rate = need to find

substituting' the given info into the equation above,

1/15 + 1/ (B's Rate) = 1/6

1 / (B's Rate) = 1/6 - 1/15 (convert right side to same denominator)

1 / (B's Rate) = 5/30 - 2/30

1 / (B's Rate) = 3/30

1 / (B's Rate) = 1/10 (taking reciprocal of both sides)

B's rate = 10 days to complete

THIS QUESTION IS EASY, I JUST NEED EXPLANATION.

chubhunter [2.5K]

It would help to have the question. But I'll guess

$\sqrt[4]{x^{\frac 3 5}}{\sqrt{x^2}} = ((x^{\frac 3 5})^{\frac 1 4}) }{ x} = x^{\frac 3{20}} x = x \sqrt[20]{x^3}$

2nd choice.

I forgot the explanation because I was so glad to have puzzled out the question.

The fourth root is the same as the 1/4 th power.

If we know x is positive $\sqrt{x^2}=|x|=x$

$\sqrt[4]{x^{\frac 3 5}}{\sqrt{x^2}}$

$= ((x^{\frac 3 5})^{\frac 1 4}) }{ x}$

We multiply the powers: $(a^b)^c=a^{bc}$

$= x^{\frac 3{20}} x$

The one-twentieth power is the twentieth root. We bring the additional factor of x to the front.

$= x \sqrt[20]{x^3}$
