What are the zeros of the polynomial function
aliya0001 [1]

Answer:

B

Step-by-step explanation:

F(x) = x^3 - 5x^2 - 6x

F(x)=x(x^2-5x-6)

F(x)=x(x-6)(x+1)

So, x=0,-1,6

Someone please help me

Let the sides of the polygon (which is a triangle, by the way) be x, y and z.  The sum of x, y and z is the perimeter of the original poly, and this equals 18 cm.

Letting f be the scale factor,   f(18 cm) = 12 cm.  Then f=2/3.

The dilation reduces the size of the polygon by a factor of 1/3, producing a similar polygon which is 2/3 the size of the original one.

In each case we have 3 side lengths but no angles.  We can use Heron's formula to obtain the area in each case.  Look up Heron's formula.  In one version of this formula, p is half the actual perimeter, meaning that p is 18 cm / 2 for the first triangle and 12 cm / 2 for the second. 

The area of the first triangle would be

A18 = sqrt( 9(9-x)(9-y)(9-z) )

whereas 

A12 = sqrt( 6(6-x*a)(6-y*a)(6-z*a) ), where a represents the dilation factor 2/3.

Then the ratio of the areas of the 2 triangles is

sqrt( 6(6-x*a)(6-y*a)(6-z*a) )
---------------------------------------
  sqrt( 9(9-x)(9-y)(9-z) )

Write the equation of a line in slope intercept form that passes through the points (0, 7) and (5, 3)
malfutka [58]

first you find the slope by making using the quation for slope

(7-3)/(0-5) and you find your slope is 4/-5. Then you can plug this into point slope form using on of the coordinates so:

y-y1=m(x-x1) --> y-3=-4/5(x-5)

then you distribute the -1 so -----> y-3=-4/5x+4 and then move the 3 over

so the answer is y= -4/5x+7

Which of the following options is a Pythagorean Identity
alexdok [17]

None of them really, but C is equivalent to the Triognometric Pythagorean Theorem:


(\sin x + \cos x)^2 = 1 + 2 \sin x \cos x


\sin^2 x + 2 \sin x \cos x + \cos ^2 x = 1 + 2 \sin x \cos x


\sin^2x + \cos ^2x = 1


That's the Trigonometric Pythagorean Theorem


Answer: C
