Answer:it would take the plane 40 seconds
Step-by-step explanation:
if you multiply by two then you would be able to get 30
like 15 times 2 and since it’s 15 miles to 20 seconds or 15:20 you would have to multiply by the same number.
Answer:
an = (1 + 2·(n - 1))/2^(n - 1) = 2^(1 - n)·(2·n - 1)
sn = 6 - 2·0.5^n·(2·n + 3)
Answer:
angle R
Step-by-step explanation:
To solve this we will use cosine rule
Cosine rule
cos(A) = 
suppose,
q = 6.25
s = 11.04
r = 13.19
angleQ = 
= 30.58
angleR = 
= 93.82
angleS = 
= 56.63
Answer: y = x^2 + 6x+ 9 = 0. (X+3)^2= 0 when x=3. This has one root.
X^2-2x -24 = 0 a= 1 b=-1 and c= -24 x = {-(-1) +/- sqrt((-1)^2 -4 x 1 x (-24)}/2
X = [1 +/- sqrt(97)]/2
Step-by-step explanation:
