Answer:
Step-by-step explanation:
A)Initial amount deposited into the account is $6500 This means that the principal is P, so
P = 500
It was compounded daily. This means that it was compounded 360 times in a year. So
n = 360
The rate at which the principal was compounded is 3%. So
r = 3/100 = 0.03
It was compounded for 5 years. So
t = 5
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore
A = 6500 (1+0.03/360)^360×5
A = 6500 (1+0.00008333333)^360×5
A = 6500 (1.00008333333)^1800
A = $7551.70
B) The interest earned is Total amount earned - principal. It becomes
7551.7 - 6500 = $1051.7
Answer:
y= -2x+8
Step-by-step explanation:
y-y₁=m(x-x₁)
This is the point slope form equation that can be used to solve this.
Plug in the slope for m and (6,-4) for (x₁,y₁)
y-(-4)=-2(x-6)
Simplify.
y+4= -2x+12
y= -2x+8
Multiply the first equation by 2 to give
10x + 2y = 20
2x - 2y = 4 Adding to elininate y
12 x = 24
x = 2
Plug x = 2 into 2x - 2y = 4
4 - 2y = 4
y = 0
so the answer is
(2,0)
Answer:
The two numbers are 58 and 60
Step-by-step explanation:
let the two numbers be x and y
then:
y+3x=234
since the two numbers are consecutive even integers then y=x+2
and since y+3x=234
then (x+2)+3x=234
then 4x+2=234
then 4x=234–2
then x=232/4=58
then the other number (y) = x+2= 58+2=60
I believe the answer is
C = 62.83cm
