What Values of X will make x2 (Exponent of 2) =16 true? HEL!!
A)4 AND -4
B)2
C)4
D)6 AND -6

A

Step-by-step explanation:

Given

x² = 16 ( take the square root of both sides )

= ± ← note plus or minus sign

x = ± 4

Since 4² = 4 × 4 = 16 and

(- 4)² = - 4 × - 4 = 16

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
