Answer:
5 seconds
Step-by-step explanation:
The relationship between "d" and "the ground" is not described. If we assume that "d" is distance above the ground, then the rock will hit the ground when d=0. This gives rise to the quadratic equation ...
-t^2 +4t +5 = 0
-(t -5)(t +1) = 0
t = 5 or t = -1 are solutions. Only the positive solution is useful.
The rock will hit the ground after 5 seconds.
Answer:
v =7/75
Step-by-step explanation:
5/3v = 125/7
cross multiply
5*7 = 125 *3v
35 = 375v divide by 375
v = 35/375
v =7/75
Answer:
2,728 words
Step-by-step explanation:
So this is a basic multiplication problem, so we just multiply the only numbers there:
88 x 31 = 2,728
So Captain's Sea Stories has 2,728 words in total
hope this helps:)
Answer:
True
Step-by-step explanation:
Its true because a scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.
