The value of integral is  2 * arc sin((x - 2) / 2) + (x - 2) * √(4 - (x - 2)²) / 2 + C.

To solve the integral ∫ √(4x - x²) dx, follow these steps:

Complete the Square: Rewrite the quadratic expression under the square root. Start with: 4x - x²

Rearrange it to the standard quadratic form: -x² + 4x. To complete the square, factor out the negative sign: (x² - 4x)

Next, complete the square inside the parentheses:

x² - 4x = (x - 2)² - 4

So, we get:

(x² - 4x) = - [(x - 2)² - 4] = 4 - (x - 2)²

Therefore:

√(4x - x²) = √(4 - (x - 2)²)

Substitute Variables: Let u = x - 2. Then, du = dx, and the integral becomes:

∫ √(4 - u²) du

Apply the Trigonometric Substitution: Use the trigonometric substitution u = 2 sin θ. Then du = 2 cos θ dθ. Substitute these into the integral:

∫ √(4 - (2 sin θ)²) * 2 cos θ dθ

= ∫ √(4 - 4 sin² θ) * 2 cos θ dθ

= ∫ √(4 (1 - sin² θ)) * 2 cos θ dθ

= ∫ 2 cos θ * 2 cos θ dθ

= ∫ 4 cos² θ dθ

Use Trigonometric Identity: Apply the double-angle identity cos² θ = (1 + cos 2θ) / 2:

∫ 4 cos² θ dθ

= ∫ 4 * (1 + cos 2θ) / 2 dθ

= ∫ (4 + 4 cos 2θ) / 2 dθ

= ∫ (2 + 2 cos 2θ) dθ

Integrate each term:

∫ 2 dθ + ∫ 2 cos 2θ dθ = 2θ + sin 2θ + C

Back-substitute: Replace θ with the original variable x. Recall u = 2 sin θ, so θ = arcsin(u / 2). Since u = x - 2, substitute back:

θ = arcsin((x - 2) / 2)

Therefore:

2 * arcsin((x - 2) / 2) + sin(2 * arcsin((x - 2) / 2)) + C

Using the identity sin(2θ) = 2 sin θ cos θ:

sin(2 * arcsin((x - 2) / 2))

= 2 * (x - 2) / 2 * √(1 - ((x - 2) / 2)²)

= (x - 2) * √(4 - (x - 2)²) / 2

5.27 can be converted to a mixed number 5 27/100, where 5 is the whole number and 27/100 is the decimal part expressed as a fraction, without reducing to lowest terms.

To convert the decimal number 5.27 to a proper fraction or a mixed number, we first recognize that .27 is the decimal part of 5.27. We can write .27 as a fraction by considering it as 27 hundredths, which is 27/100. Therefore, we have the whole number 5 and the fraction 27/100. Combining these, we get the mixed number 5 27/100. Since we are instructed not to reduce to lowest terms, the mixed number remains as is.

Answer:

The evaluation is [tex]f(-2)=-4[/tex]

Step-by-step explanation:

We were given an explicit function of x, wich has the form

[tex]f(x)=x^2+4x[/tex]

The problem ask to evaluate f(-2), this means to put the value x=-2 into the function, so

[tex]f(-2)=(-2)^2+4(-2)=4-8=-4[/tex]

Therefore, the answer is

[tex]f(-2)=-4[/tex]

The probability that you missed your friend’s call is 1/6

The range is given as:

Range = 3:00 P.M. and 5:00 P.M.

The number of minutes in the range is:

Total = 120 minutes

At 3:20 that you notice the phone is off the hook, the number of minutes missed is:

Time missed = 20 minutes

The probability is then calculated as:

P = 20/120

Evaluate

P = 1/6

Hence, the probability that you missed your friend’s call is 1/6

Answer: The simplified form will be

[tex]\frac{1}{(x+3)(x+4)}[/tex]

Step-by-step explanation:

Since we have given that

[tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]

We need to simplify the above expression, we get that

[tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}\\\\=\frac{x+1}{x^2+x-6}\times \frac{x-2}{x^2+5x+4}\\[/tex]

Now, we first factorize the quadratic equation:

[tex]x^2+x-6\\\\=x^2+3x-2x-6\\\\=x(x+3)-2(x-3)\\\\=(x+3)(x-2)[/tex]

Similarly,

[tex]x^2+5x+4\\\\=x^2+4x+x+4\\\\=x(x+4)+1(x+4)\\\\=(x+4)(x+1)[/tex]

So, it will become

[tex]\frac{x+1}{x^2+x-6}\times \frac{x-2}{x^2+5x+4}\\\\=\frac{x+1}{(x+3)(x-2)}\times \frac{x-2}{(x+4)(x+1)}\\\\=\frac{1}{(x+3)(x+4)}[/tex]

Hence, the simplified form will be

[tex]\frac{1}{(x+3)(x+4)}[/tex]

To approximate functions near zero using the linear approximation (1+x)^k ≈ 1 + kx, we find an approximation for each given function.

To approximate the function f(x) for values of x near zero using the linear approximation (1+x)^k ≈ 1 + kx, we need to find an approximation for each given function:

a.) f(x) = (1-x)^8 ≈ 1 - 8x

b.) f(x) = -8/(1-x) ≈ -8x

c.) f(x) = 1/(sqrt(1+x)) ≈ 1 - 0.5x

d.) f(x) = sqrt(4+x^2) ≈ 2 + x^2/4

e.) f(x) = (6+3x)^(1/3) ≈ 2 + x/3

Answer:

One Gallon

Step-by-step explanation:

One Imperial gallon is 4.54 litres so in that case the gallon is greater but one US gallon is only 3.79 litres so in that case the litres is bigger. ... or 1 gallon =1/. 22 =4.545 liters. so one gallon is greater than 4 liters.

Answer:

Irrational

Step-by-step explanation:

A rational number can be expressed as a ratio of two integers , p and q of the form \[\frac{p}{q}\]

So following are examples of rational numbers:

On the other hand , any number which cannot be expressed in this form is called an irrational number. For example:

The total simple interest earned on a $3000 CD over 30 months with an annual interest rate of 5.5% is $412.50 and the balance at maturity is $3412.50.

To calculate the total amount of simple interest earned on a certificate of deposit (CD) we use the formula I = Prt, where I is interest, P is the principal amount (initial amount of money), r is the annual interest rate (in decimal form), and t is the time in years. For the given 30-month CD purchased for $3000 with an annual simple interest rate of 5.5%, we first convert 30 months to years by dividing by 12 (30 / 12 = 2.5 years).

Using the formula: I = $3000 × 0.055 × 2.5 = $412.50. Therefore, the total interest earned is $412.50.

To calculate the balance at maturity, we add the total interest to the principal: Balance = Principal + Interest = $3000 + $412.50 = $3412.50.

Answer:

[tex]m{\angle}D=60^{\circ}[/tex]

Step-by-step explanation:

From the given figure, it can be seen that [tex]m{\angle}A=60^{\circ}[/tex], [tex]m{\angle}B=60^{\circ}[/tex], thus

From ΔABD, using the angle sum property, we have

[tex]m{\angle}A+m{\angle}B+m{\angle}D=180^{\circ}[/tex]

⇒[tex]60^{\circ}+60^{\circ}+m{\angle}D=180^{\circ}[/tex]

⇒[tex]120^{\circ}+m{\angle}D=180^{\circ}[/tex]

⇒[tex]m{\angle}D=180^{\circ}-120^{circ}[/tex]

⇒[tex]m{\angle}D=60^{\circ}[/tex]

therefore, the measure of [tex]{\angle}ADB[/tex] is [tex]60^{\circ}[/tex].

Hence, ΔABD is an equilateral triangle.
