4.25 inches cubed because if you do 3.5x3.5x7 =85.75 then 90-85.75=4.25
You cross multiply/butterfly method so 5•6= 30 and 5•8=40 so it would be 30/40 OR 3/4 simplified
Answer:
∠V = 33°
∠W = 90°
∠X = 57°
Step-by-step explanation:
In a right triangle, the sum of the acute angles is 90 degrees
(2x+3) + (3x+12) = 90
combine like terms
5x + 15 = 90
5x = 75
x = 15
∠V = 2x+3, x=15
2(15) + 3
30 + 3
33°
∠X = 3x+12, x=15
3(15) + 12
45 + 12
57°
The function
f(x) is even
g(x) is neither even nor odd
h(x) is odd
Steps:
for an even function it holds that f(-x) = f(x):
f(-x) = (-1)^6 x^6 - (-1)^4 x^ 4 = x^6 - x^4 = f(x) => f is even
for an odd h(x) it holds that h(-x) = -h(x):
![h(-x) = (-1)^5x^5-(-1)^3x^3 = -(x^5-x^3) = -h(x) \implies h(x)\,\, \mbox{even}](https://tex.z-dn.net/?f=h%28-x%29%20%3D%20%28-1%29%5E5x%5E5-%28-1%29%5E3x%5E3%20%3D%20-%28x%5E5-x%5E3%29%20%3D%20-h%28x%29%20%5Cimplies%20h%28x%29%5C%2C%5C%2C%20%5Cmbox%7Beven%7D)
It is easy to show that g(x) does not match any of the two possibilities above.
