Answer:

288

Step-by-step explanation:

In this expression, you can solve it by first evaluating the exponents then you can add all of the terms together.

  • 1^1 = 1
  • 2^2 = 4
  • 3^3 = 27
  • 4^4 = 256

Add all of the numbers together.

1 + 4 + 27 + 256 = 288

We know that 1^1 is 1.

We know that 2^2=4.

We know that 3^3=27.

We know that 4^4=16^2=256.

So, adding these up, we get 1+4+27+256=5+27+256=32+256=288.

6) Alberto invests $8,534 in a retirement
ludmilkaskok [199]

Answer:

  17 years

Step-by-step explanation:

The compound interest formula is ...

  A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r, compounded n times per year for t years.

Filling in the numbers and solving for t, we find ...

  16826.03 = 8534(1 +.04/12)^(12t)

  16826.03/8534 = 1.0033333...^(12t)

Taking logs, we have ...

  log(16826.03/8534) = 12t·log(1.0333333...)

Dividing by the coefficient of t gives ...

  log(16826.03/8534)/(12·log(301/300)) = t ≈ 17.000

It will take 17 years for the account balance to reach $16,826.03.

Write the following sentence into an expression using x as your variable: Myrna and Tom collect stamps. Tom has four more than h
balandron [24]

Answer: f(x) = x/2 + 4.

where f(x) is the number of stamps that Tom has, and x is the number of stamps that Myrna has.

Step-by-step explanation:

The statement is:

"Tom has four more than half the stamps that Myrna has"

For how is written, we can model the number of stamps that Tom has as a function f(x).

f(x) represents the number of stamps that Tom has, and x is the number of stamps that Myrna has.

Then:

"four more than a number" is written as:

N + 4 (where N is the number)

"Half the stamps that Myrna has" is written as:

x/2.

Then the whole statement can be modeled as:

f(x) = x/2 + 4.

notice that we have x/2, and f(x) must be a whole number, so Myrna must have an even number of stamps (in that case x/2 will be integer)

DeAngelo is training for a half marathon. Today he is running 13.25 miles. He jogs for the first half hour at a rate of 5.5 mile
Nezavi [6.7K]
For this case, the first thing we must do is define a variable.
 We have then:
 p: rate in miles per hour for the last 1.5 hours
 We now write the equation that models the problem.
 We have then:
 (0.5) * (5.5) + 1.5p = 13.25

 Rewriting we have:
 2.75 + 1.5p = 13.25

 From here, we clear the value of p.
 We have then:
 1.5p = 13.25 - 2.75

p = 10.5 / 1.5

p = 7
 Answer:
 
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour.
