Answer: The future value of the investment after 2 years is $807.8
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or amount invested.
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 2 years
P = $700
R = 7.7%
Therefore
I = (700 × 7.7 × 2)/100
I = 10780/100
I = 107.8
The total amount in the account after 2 years would be
700 + 107.8 = $807.8
Answer:
ABC = 60
BCA = 90
CAB = 30
Step-by-step explanation:
5x+9x+6+90 = 180
5x+9x = 84
14x = 84
x = 6
5x = 30
9x+6 = 60
Answer:
The correct option is;
D. -8·t² + 18·t + 6 = 10
Step-by-step explanation:
The given equation of the height toy cannon launched on top of a platform is given as follows;
h(t) = -8·t² + 18·t + 6...(1)
Where "h" represents the height in meters, at time "t" seconds after the ball is launched
When the height is 10 meters, we can write as follows;
The height of the ball, h(t) = 10
Therefore, by substituting the value of h(t) in equation (1), h(t) = -8·t² + 18·t + 6, when h(t) = 10 we get;
-8·t² + 18·t + 6 = 10.
The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.
Step-by-step explanation:
Given,
Combined length of both trails = 5760 miles
Let,
x be the length of eatern continental trail.
y be the length of Erie canal trail.
According to given statement;
x+y=5760 Eqn 1
x = 15y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 16
Putting y=360 in Eqn 2
The length of eastern continental trail is 5400 miles and length of erie canal trail is 360 miles.
