X^2 + 4x + 4 = 10<br>please help!! I missed class! show steps!​
lina2011 [118]

Answer:

x = √(10) - 2, -√(10) - 2

Step-by-step explanation:

x² + 4x + 4 = 10

factor:

(x + 2)² = 10

take square root of both sides:

x + 2 = ±√(10)

split into 2 equations:

x + 2 = √(10)      x + 2 = -√(10)

solve both equations and collect solutions:

x = √(10) - 2, -√(10) - 2

Suppose that $12,724 is invested at an interest rate of 6.1% per year, compounded continuously. Find the exponential function th
olchik [2.2K]

Answer:

Exponential Function: A= P* e ^ {0.061t}

Balance after

t=1 $ 13,524.32

t=2 $ 14,374.99

t=5 $ 17,261.69

t=10 $ 23,417.64

Step-by-step explanation:

Formula used to find amount in the account after time t, given the interest rate is compounded continuously

A= Pe^r^t

where: P= principal amount or amount invested

r= interest rate

t= time

A= amount after time t

in our question we are given:

P=$12,724

r= 6.1% or 0.061

A= 12724 * e ^ (^0^.^0^6^1^)^t

The above equation is exponential function that describes the amount in the account after time t in years

Now, for t = 1

A= 12724 * e ^ {0.061 * 1}

A= $ 13,524.32

t=2

A= 12724 * e ^ {0.061 * 2}

A= $ 14,374.99

t= 5

A= 12724 * e ^ {0.061 * 5}

A= $ 17,261.69

t=10

A= 12724 * e ^ {0.061 * 10}

A= $ 23,417.64
