It has no real solutions. To be precise, no real zeros (or roots).

The zeros (here called "solutions", I guess) are the points where the function intersects the x-axis: at those points the value of the function is zero. So they are solutions to the equation f(x)=0.

This function does not intersect the x-axis. Hence, no solutions.

Brainliest if your right and if it lets me Find the area of the blue sector. Please Can I Get Some Help! (^_^)

Contact [7]

Let's see

Area of sector

$\\ \rm\Rrightarrow \dfrac{\theta}{360}\pi r^2$

$\\ \rm\Rrightarrow \dfrac{150}{360}\pi (4)²$

$\\ \rm\Rrightarrow \dfrac{5}{12}\pi (16)$

$\\ \rm\Rrightarrow \dfrac{5}{3}\pi(4)$

$\\ \rm\Rrightarrow \dfrac{20\pi}{3}$

$\\ \rm\Rrightarrow 20.9cm²$

What is the product of 2x - 5 and 3x² + 5x - 7? Write your answer in standard form.

Akimi4 [234]

Answer:

see below

Step-by-step explanation:

(a)

$( 2x - 5 )(3x^{2} + 5x - 7)\\\\=2x(3x^2+5x-7)-5(3x^2+5x-7)\\\\=6x^3+10x^2-14x-15x^2-25x+35\\\\=6x^3+(10x^2-15x^2)+(-14x-25x)+35\\\\=6x^3-5x^2-39x+35$

(b)

$(2x-5)(3x^2+5x-7)=(5x-2)(3x^2+5x-7)\\\\\frac{1}{(3x^2+5x-7)}(2x-5)(3x^2+5x-7)= \frac{1}{(3x^2+5x-7)}(5x-2)(3x^2+5x-7)\\\\2x-5=5x-2\\\\2x-5x=-2+5\\\\-3x=3\\\\x=-1$

only happens when x=-1, not always

How many sets of three integers between 1 and 20 are possible if no two consecutive integers are to be in a set?

Dmitry_Shevchenko [17]

<span>I'm pretty sure that the solution looks like this </span> $(20-3)!(20-4)!(20-5)!...(20-19)!$ . But Also you can use this formula (r-k+1 C r). You will get 18C3.
