A certain city's population is 120,000 and decreases 1.4% per year for 15 years.

mart [117]

Answer:

Decay Problem.

Decay rate, r = 0.014
Initial Amount =120,000

$P(t)=120000(0.986)^t$
P(10)=104,220

Step-by-step explanation:

The exponential function for growth/decay is given as:

$P(t)=P_0(1 \pm r)^t, where:\\P_0$ is the Initial Population\\r is the growth/decay rate\\t is time$

In this problem:

The city's initial population is 120,000 and it decreases by 1.4% per year.

Since the population decreases, it is a Decay Problem.

Decay rate, r=1.4% =0.014
Initial Amount =120,000

Therefore, the function is:

$P(t)=120000(1 - 0.014)^t\\P(t)=120000(0.986)^t$

When t=10 years

$P(10)=120000(0.986)^10\\=104219.8\\\approx 104220 $ (to the nearest whole number)$

Solving two-step equations:

aleksklad [387]

Answer:

Mia scored 6 baskets Last Saturday.

Step-by-step explanation:

Let:

Mia made score of baskets on Last Saturday = x

Mia made score of baskets yesterday = 3x (Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. three times means multiply 3 with score of Last Saturday baskets, i.e. x)

Total score of baskets = 24

We need to find How many baskets did Mia score last Saturday?

We can write:

<em>Total Score = Score on Last Saturday + Score yester</em>day

$24=x+3x$

Solving this equation we can find value of x:

$24=x+3x\\24=4x\\=>4x=24\\x=\frac{24}{4}\\x=6$

So, we get value of x = 6

Mia made score of baskets on Last Saturday = x = 6

Mia scored 6 baskets Last Saturday.

Find the length of the leg of the right triangle leave your answer in simplest radical form

erastova [34]

Answer:

a =12*sqrt(2)

Step-by-step explanation:

3. The Pythagorean theorem states

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

a^2 +21^2 = 27^2

a^2 +441 =729

Subtract 441 from each side

a^2 +441-441 = 729 -441

a^2 =288

Take the square root of each side

sqrt(a^2) = sqrt(288)

sqrt(xy) = sqrt(x)sqrt(y)

a = sqrt(144)sqrt(2)

a =12*sqrt(2)
