What are the zeros of f(x)=x^2+x-20?
zzz [600]
F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)

f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4

Answer: C. x = -5 and x = 4.

2 sin^2 (x) -5 sin (x) -3=0
andreyandreev [35.5K]

we have that

2sin^{2} x-5sin x-3=0

I. Rewrite the equation by substituting the expression u in for sin x.

2u^{2} -5u-3=0

II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.

2u^{2} -5u-3=0 is equal to

using a graph calculator-----> see the attached figure

(u-3)*(2u+1)=0

III. Use the zero product property to solve the quadratic equation.

(u-3)*(2u+1)=0

(u-3)=0--------------> u=3

(2u+1)=0-------- 2u=-1------> u=-1/2-----> u=-0.5

IV. Rewrite your solutions to Part III by replacing u with sin x.

sin x=3--------> is not the solution (sin x can not be greater than 1)

sin x=-0.50------>is the solution

V. Solve the remaining equations for x, giving all solutions to the equation.

sin x=-0.50

if the sine is negative

then

x belong to the III or IV quadrant

we know that

sin 30°=0.50

so

the solution for the III quadrant is

x=180°+30°-------> x=210°

the solution for the IV quadrant is

x=360°-30°------> x=330°

Jack and Walter work in a store's gift-wrapping department. Jack can wrap 28 boxes in 2 hours, while Walter takes 3 hours to wra
kodGreya [7K]

Answer:

C.

Step-by-step explanation:

Jack's rate = 28/2 = 14 boxes/hour

Walter's rate = 36/3 = 12 boxes/hour

Combined rate = 14 + 12

= 26 boxes/hour

26 = 65/t

26t = 65
