KengaRu [80]

Answer:

a = 3.5

Step-by-step explanation:

Let's find 'a' using Pythagoras theorem.

=> 4² = 2² + a²
=> 16 = 4 + a²
=> 12 = a²
=> a = √12
=> a = √2 x 2 x 3
=> a = 2√3
=> a = 2 x √3
=> a = 2 x 1.732
=> a = 3.464 = 3.5 (Estimated)

A manufacturing plant earned \$80$80dollar sign, 80 per man-hour of labor when it opened. Each year, the plant earns an addition

vagabundo [1.1K]

Answer:

$A(t)=80(1.05)^t$

Step-by-step explanation:

The manufacturing plant earned $80 per man-hour of labor when it opened

The plant earns an additional 5% for every additional man-hour t.

This can be modeled using the function:

$A(t)=P(1+r)^t$

where Initial Amount Earned, P=80

Rate of Increase, r=5%=0.05

Therefore, the function that models the amount earned at any time t is:

$A(t)=80(1+0.05)^t\\A(t)=80(1.05)^t$
