Answer:
Step-by-step explanation: I think you skip count by 50s or something like that. So, it has to be 64.
Find the possible rational roots and use synthetic division to find the first zero.
I chose x=1 (which represents the factor "x-1")
1║2 -7 -13 63 -45
║ 2 -5 -18 45
2 -5 -18 45 0
(x-1) is a factor, (2x³ - 5x² - 18x + 45) is the other factor.
Use synthetic division on the decomposed polynomial to find the next zero.
I chose x = 3 (which represents the factor "x-3")
3║2 -5 -18 45
║ 6 3 -45
2 1 -15 0
Using synthetic division, we discovered that (x-1), (x-3), & (2x² + x -15) are factors. Take the new decomposed polynomial (2x² + x -15) and find the last two factors using any method.
Final Answer: (x-1)(x-3)(x+3)(2x-5)
5x + 3 = 38
5x = 38 + 3
5x = 35
x = 35/5
x = 7
Answer:
Therefore multiplying x by a number between 0 and 1 creates a horizontal stretch, which looks like a vertical compression. That is, the parabola will be shorter/wideStep-by-step explanation:
Answer:
m∠Z = 166°
Step-by-step explanation:
Since we know that the angles add up to 720°, we can set up an equation to solve for the variable x:
12x + 14x - 6 + 108 + 108 + 108 + 90 = 720
26x + 408 = 720
26x = 312
x = 12
Now we substitute the number in for x to solve ∠Z:
m∠Z = 14(12) - 2 = 166
m∠Z = 166°
