4 hours
using the formula
distance = speed × time (t)
the Ford will have travelled 3 × 40 = 120 miles before the Chevy leaves
the Ford's distance can be modelled as
distance = 40t + 120
the Chevy's distance can be modelled as
distance = 70t
equating the right sides and solve for t
70 t = 40t + 120 ( subtract 40t from both sides )
30t = 120 ( divide both sides by 30 )
t = 4
the Chevy catches up with the Ford after 4 hours
Answer:
Below in bold.
Step-by-step explanation:
(a) Using the Pythagoras theorem:
30^2 = 21^2 + p^2
p^2 = 30^2 - 21^2 = 459
p = √459
= 21.4 cm to nearest tenth.
(b) cos P = 21/30 = 0.70
m < P = 45.57 degrees to nearest hundredth.
Answer:
C
Step-by-step explanation:
Note that each of the y- coordinates is the x- coordinate raised to the power of 4.
(1, 1) → y = 
= 1
(2, 16) → y = 
= 16
(3, 81) → y = 
= 81
(4, 256) → y = 
= 256
(5, 625) → y = 
= 625
Thus the rule is y = 
→ C
