Use a calculator. And I am surprised because none of the options is the correct answer.

The answer is 5.

The graph touches the x-axis at only 1 point. This means the equation of the graph must be a product of a perfect square and a real constant, in this case:

\(y = k(x + 1)^2\)

When x = 0, y = 2.

\(2=k\cdot 1^2\\ k = 2\)

Therefore, the equation of the parabola is \(y = 2(x + 1)^2\).

If it is a square with one of the vertices being the origin, then two of the vertices lies on |y| = |x|, in this case, two of the vertices lies on y = -x.

We solve the system of simultaneous equations

\(\begin{cases}y = 2(x + 1)^2\\y = -x\end{cases}\)

I will leave the rest for you.

i use this because i dont know how use a calculator xD and i don now 8^1 /3 xD express

The complete answer is (-1/2, -7/75), with the brackets. You don't just enter -1/2 and call it done.

Asking a question twice doesn't mean you get your answers more quickly.

This solely depends on what you meant by that notation.

If you meant \(\dfrac{8^1}3\) then it's 8/3.

If you meant \(8^{1/3}\) then it's 2.

Or maybe you can use a calculator, so you don't need to wait for people to reply.

When I enter -1/2 it says partially correct!! It is asking for another value!

Drawing the diagram and using Pythagorean theorem directly,

\(\text{Length of one cable} = \sqrt{6^2 + 8^2} = 10 \text{ ft}\)

And you can do the rest.

From ac + b = 18, we can see that 

a(c - 1) + (a + b) = 18

a(c - 1) + 3 = 18

a(c - 1) = 15 --- (1)

Similarly,

bc + a = 6

b(c - 1) + (a + b) = 6

b(c - 1) = 3 --- (2)

Adding (1) and (2) would give the required value.

Ans: c = 7

\(f(x) = \dfrac{3x^2 + 3x + 6}{x^2 + x - 56} = 3 - \dfrac{58}5 \left(\dfrac{1}{x + 8} - \dfrac1{x - 7}\right)\)

Differentiating, \(f'(x) = \dfrac{58}5\left(\dfrac1{(x + 8)^2} - \dfrac1{(x - 7)^2}\right)\)

When \(f'(x) = 0\),

\((x - 7)^2 - (x + 8)^2 = 0\\ 2x + 1 = 0\\ x = -\dfrac12\)

Also, \(f\left(-\dfrac12\right) = -\dfrac7{75}\), so the critical point is \(\left(-\dfrac12, -\dfrac7{75}\right)\), and there is only 1 critical point, not 3.

i am pretty sure there's 12 different ways

Thank you! : )

Like in a straight line?

Using pythog. thereom

sqrt(28^2 +47^2) = sqrt(2993) km

OR you add 28 to 47 if you wanted to know the distance the boat traveld, not the distance relative to the starting point.

1/19 since there are 1000-50=950 numbers and there are 100-50=50 2 digit numbers so 50/950=1/19

thanks (it is correct)

There are 50-99 of two digit numbers

THus, 1 - 50

50 numbers.

50-999 becomes 1 - 950

So we have 50/950 = 5/95 = 1/19

Is this correct?

March 2014 was like this

Had 5 mondays, 4 wednesdays, 4 fridays.

SO.

He must pay for 13 days.

Single pass... 26*2 = 52$

Thus single trip is the best.

ALso waht does UYU mean

Ok! Great!

you are right(it is 1/2)

It's rational or irrational

Why?

If you multiply an irrational number by 0, it's rational.

See what I mean?

It's (c)

If you don't understand anything feel free to ask.

it is 1/2

It means

"you are him very hot"

In chinese

and in other languages idk since chinese is the only foreign language I know... other than a snippet or two of spanish
