3/7 * -2 1/5 = (turn ur mixed number into an improper fraction)
3/7 * - 11/5 = (now just multiply straight across)
(3 * -11) / (7 * 5) = -33/35 <====
Answer:
Option C: (4.47,-0.46)
Step-by-step explanation:
To convert Cartesian coordinates into polar coordinates , use the following formulas:
Therefore:
Because (4,-2) is located in Quadrant II, the angle must also be located in Quadrant II. Therefore, the correct polar coordinate would be (4.47,-0.46)
Answer:
Step-by-step explanation:
Let x be the number.
4x -8 < 56
x ={ ........-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}
Answer:
Number of 1 point shots = 16
Number of 2 point shots = 36
Step-by-step explanation:
Let,
x be the number of 1 point shots
y be the number of 2 point shots
According to given statement;
x + y = 52 Eqn 1
x + 2y = 88 Eqn 2
Subtracting Eqn 1 from Eqn 2
x + 2y - x - y = 88 - 52
y = 36
Putting y = 36 in Eqn 1
x + 36 = 52
x = 52 - 36
x = 16
Hence,
Number of 1 point shots = 16
Number of 2 point shots = 36
Answer:
The possible values for x are 4 and 0.25.
Step-by-step explanation:
In order to solve for "x" in the equation we first need to sum "x" and "1/x", to do that we must apply LMC as shown below:
x + 1/x = 17/4
(x² + 1)/x = 17/4
4*(x² + 1) = 17*x
4*x² + 4 = 17*x
4*x² + 4 - 17*x = 0
4*x² - 17*x + 4 = 0
x = [-(-17) + sqrt((-17)² - 4*(4)*(4))]/(2*4) = 4
x = [-(-17) - sqrt((-17)² - 4*(4)*(4))]/(2*4) = 0.25
The possible values for x are 4 and 0.25.
