Question 22 A city has a population of people. Suppose that each year the population grows by . What will the population be afte

Alexeev081 [22]

Answer:

911,690.

Step-by-step explanation:

Please consider the complete question.

A city has a population of 390,000 people. Suppose that each year the population grows by 6.75%. What will the population be after 13 years? Round your answer the nearest whole number.

We will use exponential growth formula to solve our given problem.

$y=a\cdot (1+r)^x$ , where,

y = Final value,

a = Initial value,

r = Growth rate in decimal form,

$6.75\%=\frac{6.75}{100}=0.0675$

$y=390,000\cdot (1+0.0675)^x$

$y=390,000\cdot (1.0675)^x$

To find the population after 13 years, we will substitute $x=13$ in population growth equation as:

$y=390,000\cdot (1.0675)^{13}$

$y=390,000\cdot 2.3376661492982871$

$y=911689.798226331969$

Upon rounding to nearest whole number, we will get:

$y\approx 911,690$

Therefore, the population of the city after 13 years would be 911,690.

I'LL MARK BRAINLIEST PLEASE HELP

Fudgin [204]

<h3>Answer:</h3>

The number is 72

<h3 /><h3>Step-by-step solution:</h3>

Its hard to explain this really. Its kind of like a trial-and-error. Multiplying numbers by 8 with the second digit being 5 more than the units digit.

It takes time but eventually, youll find the answer.

Plus, You can search it up since theres already a pre-existing answer to this same question.

A=63°

bekas [8.4K]

Answer:

B. 7.35 inches

Step-by-step explanation:

In the triangle:

A=63°
c = 7.75 inch
B = 47°

Now we know that:

$\angle A+\angle B+\angle C=180^\circ$ (Sum of angles in a \triangle)\\63^\circ+47^\circ+\angle C=180^\circ\\\angle C=180^\circ-(63^\circ+47^\circ)\\\angle C=70^\circ$

Using the Law of Sines

$\dfrac{a}{\sin A} =\dfrac{c}{\sin C}\\\\\dfrac{a}{\sin 63^\circ} =\dfrac{7.75}{\sin 70^\circ} \\\\a=\dfrac{7.75}{\sin 70^\circ} \times \sin 63^\circ\\\\a=7.35$ inches (to the nearest hundredth of an inch)$
