Answer:
t=-14
Step-by-step explanation:
subtract 17 from each side
 
        
                    
             
        
        
        
F(x)......ur output = 19
19 = 2x^2 + 3x + 5
2x^2 + 3x + 5 - 19 = 0
2x^2 + 3x - 14 = 0
(2x + 7)(x - 2) = 0
2x + 7 = 0
2x = -7
x = -7/2
x - 2 = 0
x = 2
I believe there is 2 possible answers......x (ur input value) = -7/2 or 2
        
             
        
        
        
Answer:
(1.5,-2.6)
Step-by-step explanation:
Given the polar coordinates (-3,60°).
Let our Cartesian coordinates be (x,y)
#We know that when converting the rectangular coordinates (x,y) to polar (r,θ), then:

#Using the illustration above, we can express our polar coordinates as:

#Solve simultaneously to solve for x and y:

Hence, the Cartesian coordinates are (1.5,-2.6)
 
        
             
        
        
        
I think so 12 to 13 minutes will it take to use all sheets..
