Answer:
0.03%
Step-by-step explanation:
Simple interes = PRT/100
Given
Interest = $590.00
Principal P = $8000
Time T = 285 days
Rate = ?
Since I = PRT/100
R = 100 x I /PT
= 100 x $590.00 /$8000 x 285
Multiply through
= 59000/2280000
= 0.03%

Step-by-step explanation:
Answer: 800 feet²
Step-by-step explanation:
Lets remove the brackets from the function's expression
A(x) = -2x²+80x
So we got the quadratic function and we have to find the x that corresponds to function's maximum. Let it be X max
As we know Xmax= (X1+X2)/2 , where X1 and X2 are the roots of the function A(x)
Lets find X1 and X2
x(80-2x)=0
x1=0 80-2*X2=0
x2=40
So Xmax= (0+40)/2=20
So Amax= A(20)= 20*(80-2*20)=20*40=800 feet²
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.
