Answer:
I'm sorry, I'm not really certain of anything except part A
Step-by-step explanation:
Part A
First of all write the function.
Let x = the number of hours traveled. The y intercept is the value when x = 0
y = 2x + 50 Every 1 hour, the speed increases by 2 mph
(1) The y intercept is 0,50
(2) The car was travelling at 50 mph to begin with.
Part B
Average speed = total distance covered / time interval
Distance between 1 and 2 = 52 + (54 - 52)/1 = 54
Distance between 2 and 3 = 54 + (56 - 54)/1 = 56
Average = (54 + 56)/2 = 55
Part C
I don't see how Part C has any answer. It must change motion even if it winds up where it started from (in which case the velocity cannot be both 60 and 0 at the same time)
I think they want you to answer 0.
Given:
Principal = $1400
Simple rate of interest = 1.25%
Time = 6 month
To find:
The balance of the account after simple interest.
Solution:
The formula for simple interest is
Where, P is principal, r is the rate of interest in % and t is time in years.
Time = 6 months
= year
= 0.5 year
Putting 1400, r=1.25, t=0.5 years.
Now, the amount is
Therefore, the balance of the account after the simple interest is $1408.75.

Answer:
James is correct
Step-by-step explanation:
Given the expression wrote by a meteorologist as 78 + (-6), If James believes that this expression is the same as 78-6 then James is correct because if the parenthesis is expanded the product of the addition and the subtraction sign will produce a negative sign i.e + * - = -
78 + (-6) = 78 - 6 = 72
Based on the conclusion, we can say that James is correct in his reasoning
The origin is at the point (0,0). Therefore, the y-intercept will be 0. For two points to be perpendicular, the slopes must be opposite reciprocals of each other. .5 can be seen as 1/2, so the reciprocal is 2, and it is positive, making that 2 negative. Your equation would be y = -2x.
