Answer:
A(10) = $13,961.50
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 5.25/100
r = 0.0525 rate per year,
Then solve the equation for A
The formula is given as:
A = Pe^rt
P = 8259
r = 0.0525
t = 10 years.
Hence, 
A = 8,259.00 × e^(0.0525×10)
A = $13,961.50
Therefore, the money that will be in the account after 10 years is $13,961.50

Answer:
d) 1/2 ÷ 4 = 1/2 • 4/1
Step-by-step explanation:
when dividing fractions use keep change flip (keep the first fraction, change the sign to multiplication, flip the second fraction)
when multiplying just multiply straight across
 
        
             
        
        
        
Answer: ∠1 = 109°    ∠2 = 71°
<u>Step-by-step explanation:</u>
If the two angles form a linear pair, then their sum is 180°
   ∠1      +     ∠2     = 180°
(5x + 9) + (3x + 11) = 180
               8x + 20  = 180
               8x          = 160
                 x          = 20
∠1 = 5x + 9
     = 5(20) + 9
     = 100   + 9
     = 109
∠2 = 3x + 11
      = 3(20) + 11
      =    60  + 11
      =         71
   <u> CHECK:</u>
 ∠1   + ∠2 = 180°
109° + 71° = 180°
      180°   = 180°
