3. The population P in thousands of a city can be modeled by the equation

madreJ [45]

Answer:

27 years

Step-by-step explanation:

P is measured in thosands therefore, P will have a value of 120

so it would be...

120=80e^0.015t

80e^0.015t=120

e^0.015t=120/80=3/2=1.5

e^0.015t=1.5

0.015t= In(1.5)

t=In(1.5)/0.015

∴ t≈27.03 round it to 27 years

It would be greatly appreciated if you gave me the brainlest

Find the value of expression - 17x-19xpwer4 - 21x power 2,when x=3<br><br>

Marrrta [24]

Answer:

$-17x - 19x^4 - 21x^2 = -1779$ when $x = 3$

Step-by-step explanation:

Given

$-17x - 19x^4 - 21x^2$

$x = 3$

Required

Solve

Substitute 3 for x in $-17x - 19x^4 - 21x^2$

$-17x - 19x^4 - 21x^2 = -17*3 - 19*3^4 - 21*3^2$

Evaluate all exponents

$-17x - 19x^4 - 21x^2 = -17*3 - 19*81 - 21*9$

$-17x - 19x^4 - 21x^2 = -51 - 1539- 189$

$-17x - 19x^4 - 21x^2 = -1779$
