Answer: he needs to add $277.5
Step-by-step explanation:
The formula for continuously compounded interest is
A = P x e(r x t)
Where
A represents the future value of the investment after t years.
P represents the present value or initial amount invested
r represents the interest rate
t represents the time in years for which the investment was made.
From the information given,
P = $7,000
r = 5.5% = 5.5/100 = 0.055
t = 4 years
Therefore,
A = 7000 x e(0.055 x 4)
A = 7000 x e(0.22)
A = $8722.5
After four years, he wants to buy a used car for $9,000. Therefore, the additional amount that he needs to add is
9000 - 8722.5 = $277.5
Answer:x=-10
Step-by-step explanation: We need to find the slope of the line to find equation.
slope of line x=3 is infinity.
equation of line parallel to x=3 will have same slope.
point given=(-10,3)
equation of line: (y-y1)=slope(x-x1)
= (y-3)=∞(x+10)
= (y-3)/∞=x+10
=0=x+10
=x=-10
Answer: 480300
Step-by-step explanation:
800 * 600 + 200 + 100
480000 + 200 + 100
480000 + 300
480300
2420 cups in March
1660 cups in April
2420 + 1660 = 4080
4080/4 = 1020
The cafeteria served 1020 total quarts of milk in March and April
Answer:
Explanation:
Take two points: (1, 1), (-1, 0)
Find slope:
Equation:
⇒ y - y₁ = m(x - x₁)
⇒ y - 1 = 1/2(x - 1)
⇒ y = 1/2x - 1/2 + 1
⇒ y = 1/2x + 1/2
