Answer:
b. -4
Step-by-step explanation:
Every time one x value increases the y value decreases by 4. In the x values shown the number that should come after -4 is -3 so the y values -2 and -2 that are 8 units apart should be halved and be -4. This function maintains a constant rate of change throughout the function.
Answer: x = 64°
Step-by-step explanation: Subtract all the values given from 360°.
Answer:
The length of the leg is 13.416
Step-by-step explanation:
To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras
h = hypotenuse = 18
a = leg 1 = 12
b = leg 2 =
h² = a² + b²
we replace the known values and solve
18² = (12)² + (a)²
324 = 144 + (a)²
324 - 144 = (a)²
324 - 144 = (a)²
√180 = a
13.416 = a
The length of the leg is 13.416
