Answer:
210 Km
Step-by-step explanation:
Distance travelled is calculated as
distance = speed × time ( time is in hours )
= 90 × 2 
= 90 × 
= 30 × 7
= 210 Km
Answer:
Step-by-step explanation:
C is the correct answer. Multiply each element of the matrix by -3:
-3(2) = -6, and so on.
Answer:
38.57 feets
Step-by-step explanation:
Given that:
Height of monument, h = 300ft
Shadow of monument, s = 210 ft
Shadow of tree, s = 27ft
Height of tree, = x
Using the relation :
Height / shadow = height / shadow
Monument = tree
300 / 210 = h / 27
Cross multiply
300 * 27 = 210 * h
8100 = 210h
h = 8100 / 210
h = 38.57 feets
X^2 + 6x = 13
x^2 + 6x + 9 = 13 + 9
(x + 3)^2 = 22
x + 3 = (+,-) sq rt 22
x = -3 + (sq rt 22) and x = -3 - (sq rt 22)
Answer:
midpoint is y2+y1/2, x2+x1/2 therefore 3+1/2,-6+-4/2,4/2,-10/2 and the answer is (2,-5 )
