4 to the 8th power divided by 4 to the 5th power
Natasha2012 [34]

Alright, 4 to the 8th power is 4x4x4x4x4x4x4x4 which ends up as 65,536.

4 to the 5th power is the same thing but with 5 4's and that is 1,024.

All you need to do now is 65,536/1,024 = 64.

Solved!  :D

Answer:

53 Meters.

Step-by-step explanation:

34*34 + 41*41 = 2837.

1156 + 1681 = 2837.

The square root of 2837 would be your answer.

34*34 + 41*41 = 53.26349 * 53.26349

a*a + b*b = c*c.

a² + b² = c².

Simplify h= 105sin (0.0698(90+1)) + 105
IrinaK [193]

Answer:

h= 116.616

Step-by-step explanation:

we have

h= 105sin (0.0698(90+1)) + 105

step 1

Solve (90+1)

h= 105sin (0.0698(91)) + 105

step 2

Solve 0.0698(91)

h= 105sin (6.3518) + 105

step 3

Solve sin (6.3518)

h= 105(0.11063) + 105

step 4

Solve 105(0.11063)

h= 11.616 + 105

step 5

Solve 11.616 + 105

h= 116.616

Danny decided to invest his $500 tax refund rather than spending it. He found a bank that would pay him 4% interest, compounded
Blababa [14]
Present value, PV = $500
Future value, FV = 2*PV = 2*500 = $1,000
Rate, r = 4% = 0.04
Compounding times in a year, n = 4 (compounded quarterly)
Time, t = ??

The future value expression is stated as:
FV = PV (1+r/n)^nt

Substituting;
1000 = 500 (1+0.04/4)^4t
2 = (1.01)^4t
ln 2 = 4t ln 1.01
0.6931 = 4t* 0.00995
0.6931 = 0.0398t
t = 17.414 years

Time required for the amount to double is 17.41 years.
