Answer:
Step-by-step explanation:
penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei.
Answer:
Step-by-step explanation:
f(x) = 2x² + 14x - 4
= 2(x² + 7x) - 4
= 2(x² +7x + 3.5²) - 2(3.5²) - 4
= 2(x+3.5)² - 28.5
vertex (3.5, -28.5) = (7/2, -57/2)
The vertical intercept is the y-intercept, i.e., f(0) = -4.
The x-intercepts are the values of x for which y=0.
2x² + 14x - 4 = 0
x = [-14±√(14²-4(2)(-4))]/[2(2)] = [-7±√57]/2 ≅ -7.27, 0.27
7/20 converts to 35/100, so as a percent it is 35% and as a decimal it is .35.
Answer:
2
Step-by-step explanation:
If it ends in an even number, it is divisible by an even number
