Which real numbers are zeros of the function? f(x)=2x4−9x3+7x2+6x

-1/2, 0, 2, and 3 are the answers

 The real zeroes of the function f(x) are

Step-by-step explanation:  We are given to find the real numbers that are zeroes of the following functions :

We know that

the zeroes of a polynomial function y = p(x) are given by p(x) = 0.

So, the zeroes of the given polynomial (i) are

So, one of the real zeroes of f(x) is x = 0 and the other zeroes are given by

Factor theorem :  If at x = a, the value of a function p(x) is zero, then (x-a) is a factor of p(x).

Let us consider that

At x = 1, we have

At x = 2, we have

So, (x-2) is a factor of g(x).

Therefore, we get

That is, the other two zeroes are given by

Since all the four zeroes are real, so all the real zeroes of f(x) are

Thus, the real zeroes of the function f(x) are

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
