The answer is 4/8 because half of 16 is 8 and half of 8 is 4, therefore they are equivalent
Answer:
E
Step-by-step explanation:
Given
y = 2x² - kx + 3
with a = 2, b = - k and c = 3
Since the curve touches the x- axis at one place then the roots are real and equal and the discriminant for this condition is
b² - 4ac = 0, that is
(- k)² - (4 × 2 × 3) = 0
k² - 24 = 0 ( add 24 to both sides )
k² = 24 ( take the square root of both sides )
k = ± 
= ± 2
k = 2 or k = - 2 → E

Hello ♡
The answer to your question is 7.3333333333 .
Step-by-step explanation:
Hope this helps u ;)
We have a15 = a1 + 14 x r and a21 = a1 + 20 x r <=> 29 = a1 + 14 x r and 47 = a1 + 20 x r;
Then, 47 - 29 = (20 x r + a1) - (14 x r + a1);
18 = 6 x r;
r = 3;
We have 29 = a1 + 42;
a1 = 29 - 42;
a1 = - 13;
Finally, a5 = a1 + 4 x r = -13 + 4 x 3 = -13 + 12 = -1.
