in 2010 , a city's population was 55,210 and it was declining at a rate of 1.09% each year. which is the best prediction for whe

Anon25 [30]

Answer: 2023

Step-by-step explanation:

Since, the initial population of the city is 55,210,

And, it is declining at a rate of 1.09%.

Thus, the function that shows the population after x years since 2010 is,

$f(x) = 55210(1-\frac{1.09}{100} )^x$

$f(x) = 55210(1-0.0109)^x$

$f(x) = 55210(0.9891)^x$

If the population of town is 48000 in x years.

⇒ $55210(0.9891)^x= 48000$

⇒ $(0.9891)^x= 0.869407715993$

⇒ $x = 12.769$

Therefore, after 12.769 years the population of town will be equals to 48,000

⇒ After 12.770 years the population will first be below 48,000.

⇒ After approx 13 years the population will first below 48,000.

⇒ Around 2023 the population will be first below 48,000.

Find the missing the side of the triangle. 19New A. 73‾√ in B. 72‾√ in C. 75‾√ in D. 77‾√ in

valina [46]

By applying Pythagorean's theorem, the missing side of this right-angled triangle is: A. 7√3 inches.

<h3>How to find the missing side?</h3>

By critically observing the triangle shown in the image attached below, we can logically deduce that it is a right-angled triangle. Thus, we would find the missing side by applying Pythagorean's theorem:

z² = x² + y²

Also, the sides of this right-angled triangle are:

Hypotenuse = 14 inches.

Opposite side = x inches.

Adjacent side = 7 inches.

Substituting the given parameters into the formula, we have;

14² = x² + 7²

196 = x² + 49

x² = 196 - 49

x² = 147

x = √147

x = √49 × √3

x = 7√3 inches.

-3(u+2)=5u-1+5(2u+1)

Mazyrski [523]

Answer:

u = -5/9

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

-3(u + 2) = 5u - 1 + 5(2u + 1)

Step 2: Solve for u

Distribute: -3u - 6 = 5u - 1 + 10u + 5
Combine like terms: -3u - 6 = 15u + 4
Add 3u to both sides: -6 = 18u + 4
Subtract 4 on both sides: -10 = 18u
Divide 18 on both sides: -10/18 = u
Simplify: -5/9 = u
Rewrite: u = -5/9

Step 3: Check

Plug in u into the original equation to verify it's a solution.

Substitute in u: -3(-5/9 + 2) = 5(-5/9) - 1 + 5(2(-5/9) + 1)
Multiply: -3(-5/9 + 2) = -25/9 - 1 + 5(-10/9 + 1)
Add: -3(13/9) = -25/9 - 1 + 5(-1/9)
Multiply: -13/3 = -25/9 - 1 - 5/9
Subtract: -13/3 = -34/9 - 5/9
Subtract: -13/3 = -13/3

Here we see that -13/3 does indeed equal -13/3.

∴ u = -5/9 is a solution of the equation.

How can you show that two objects are proportional with an equation

Zina [86]

The equation has to (or be transformed to) contain one object in the left side and the other object at the right side multiplied by a constant, without an independent term.
