When multiplying two powers that have the same base, you can add the exponents
Answer:
-14√2
Step-by-step explanation:
Note that 18 = 2*9, and that 9 is a perfect square. Therefore,
2*√18 = 2*3*√2, or 6√2.
Next, note that 32 = 2*16, and that 16 is a perfect square. Therefore,
-5*√32 = -5*√2*√16, or -5*√2*4, or -20√2.
Combining these two results, we get:
6*√2 - 20√2, or -14√2
4000000/6000=666.67
(1+r)^200=666.67
ln (1+r)^200=ln 666.67
200 ln (1+r)=ln 666.67
e^ln (1+r)=e^.03251145
1+r=1.0330457
r=0.0330457, or 3.30457% APR
Answer:
<em>1,172.5cm²</em>
Step-by-step explanation:
Total surface area of a box = 2(LW + WH + LH)
L is the length = 11.5cm
W is the width = 7cm
H is the height = 1.5cm
Substitute
TSA = 2(11.5(7) + 7(1.5) + (11.5)(1.5))
TSA = 2(80.5+10.5+17.25)
TSA = 2(117.25)
TSA = 234.5cm²
<em>Hence the total surface area of a stack of five such compact disc boxes will be 5(234.5) = 1,172.5cm²</em>
