Answer:
When x = 6.
Step-by-step explanation:
WE need to solve the system:
y = - x^2 + 4x + 4
y = -2x + 4
Equating:
- x^2 + 4x + 4 = -2x + 4
0 = x^2 - 4x - 4 - 2x + 4
x^2 - 6x = 0
x(x - 6) = 0
x = 0, 6.
Answer:
geometric sequence; common ratio: 2
Step-by-step explanation:
because you would have to multiply a number to get to the next and the next number in line, this is geometric. The common ratio is 2 because each time the number increases you multiplying by two
Solution: It would be quadrupled because radius controls to axis (height & width) meaning if you double two (2 x 2) you get four (4).
Answer: $5000; $2000
Step-by-step explanation:
Simolw interest is calculated as: PRT/100
where,
P = principal
R = rate
T = time
Let the money in the 4-yr cd be represented by y.
Since rate = 5.2%
Simple interest = (y × 5.2 × 4)/100
Since he invested $3000 less in a 18-month CD, Let the money in the 18-month CD be represented by (y - $3000).
Then, S.I = [(y - $3000) × 3 × 1.5]/100
The total interest = $1130
We then equate the two simple interest together. This will be:
= (y × 5.2 × 4)/100 + (y - $3000) × 3 × 1.5]/100 = $1130
0.208y + 0.045(y - $3000) = $1130
0.208y + 0.045y - $135 = $1130
0.253y = $1130 + $135
0.253y = $1265
y = $1265/0.253
y = $5000
The money invested in 4-yr CD = $5000
The money invested in the 18-month CD = $5000 - $3000 = $2000
