By the concept of basic arithmetic solo acts are 5 minutes long and ensemble acts are 15 minutes long

Mathematics' fundamentals are arithmetic operations. Addition, subtraction, multiplication, and division are the main operations that make up this concept. The phrase "mathematical operations" also refers to these.

The math operation of subtracting two integers reveals the difference between them. The '-' sign is used to indicate it. In math, subtraction is the process of taking one number away from another to determine what is left over after something has been taken away. Rational number operations are equivalent to those performed on whole numbers. The main distinction is that rational numbers take the form p/q, where p and q are integers and q is not equal to 0. It is necessary to take the LCM of the numerators when adding or subtracting two rational integers.

Here we are discussing the four basic rules of arithmetic operations for all real numbers.

12 × x + 2 × y = 90

6 × x + 2 × y = 60

To write system of equation you just need to sum all solo and ensemble acts and make it equal to how much they will last for.

B.  Here we can multiply second equation with negative 1 and add it to first equation.

6x = 30

x = 5

Now we replace x in any of 2 equations to get y.

30 + 2y = 60

2y = 30

y=15

The volume of the cylinder is 6.18 \(cm^3\).

The volume of a cylinder—which corresponds to how much material can be transported inside of it or immersed in it—determines its density. The volume of a cylinder is calculated using the formula \(r^2h\), where r is the radius of the circular base and h is the height of the cylinder. The material might be any substance that can regularly fill the cylinder with liquid or another substance.

Use the following formula to determine a cylinder's volume:

V = π\(r^2h\)

where r is the radius of the cylinder (diameter / 2), h is the height of the cylinder, and π is approximately equal to 3.14.

First, find the radius:

r =\(\frac{ 1.26}{ 2}\)

r = 0.63 cm

Next, find the volume:

V = π\(r^2h\)

V = π\((0.63)^2(5.0)\)

V= π * 0.3969 * 5.0

V= 3.14 * 0.3969 * 5.0

V = 6.18 \(cm^3\) (rounded to 2 decimal places).

So, the volume of the cylinder is 6.18 \(cm^3\).

a-5=0 or a-15=0

a=5 or a=15

b=15 or b=5

(:

Answer:

Step-by-step explanation:

 a + b = 20

Sum of roots = 20

ab = 75

Product of roots = 75

x² - (a +b) x + ab = 0

x² - 20x + 75 = 0

Sum = coefficient of x = -20

Product = 75

Factors = 15 , 5    {15*5 = 75  & 15 +5 = 20}

x² - 15x - 5x + 75 = 0  {Rewrite the middle term}

A function assigns the values. The output(y) of the function y=20x + 38 if the input is -9 is -142.

A function assigns the value of each element of one set to the other specific element of another set.

Given the function y=20x+38, therefore, if the input of the function is -9, then the output can be calculated by substituting the value of x as -9. Therefore, we can write the function as,

y = 20x + 38

y = 20(-9) + 38

y = -180 + 38

y = -142

The area of a triangle is Area = sqrt(s(s-x)(s-y)(s-c)).

The area of a triangle can be found using the Heron's formula if we know the lengths of all three sides, or using the formula (1/2) * x * y if we know the lengths of two legs and the triangle is a right triangle.

In the case where the legs of the triangle are x and y long, if we don't know if the triangle is a right triangle, we can't use the formula (1/2) * x * y. However, we can use Heron's formula to calculate the area. Heron's formula states that the area of a triangle is equal to the square root of s(s-a)(s-b)(s-c), where s is the semi-perimeter of the triangle and a, b, and c are the lengths of the three sides.

In this case, since we know the lengths of the two legs x and y, we can find the area of the triangle using Heron's formula as follows:

s = (x + y + c)/2

Area = sqrt(s(s-x)(s-y)(s-c))

Where c is the length of the hypotenuse of the triangle, this information is not provided, so we cannot calculate the area of the triangle.

Therefore, The area of a triangle is Area = sqrt(s(s-x)(s-y)(s-c)).

There are 72 different bracelets with 4 identical red beads, 4 identical orange beads, and 2 yellow beads, after flipping a bracelet.

To find the number of different bracelets, we can use the concept of permutations.

First, let's consider the red beads.

Since there are 4 identical red beads, the number of ways to arrange them in a line is 4! (4 factorial).

However, since rotating the bracelet does not change it, we need to divide by 4 to account for the different rotations of the same arrangement.

So, the number of arrangements of the red beads is 4!/4 = 6.

Next, let's consider the orange beads.

Similarly, there are 4!/(4 * 2) = 12 different arrangements of the orange beads.

Again, we divide by 4 to account for the different rotations.

Lastly, we have the yellow beads. Since there are 2 identical yellow beads, there is only 1 arrangement for them.

To find the total number of different bracelets, we multiply the number of arrangements for each type of bead:

6 * 12 * 1 = 72.

Therefore, there are 72 different bracelets with 4 identical red beads, 4 identical orange beads, and 2 yellow beads, if rotating or flipping a bracelet does not change it.

Yes, it is necessary that both the functions f(x) and g(x) are continuous at x = 0 in order for the product function h(x) = f(x) g(x) to be continuous at x = 0.

Continuity means that a function is both defined and has no abrupt changes in its value at a certain point. This means that both f(x) and g(x) must be defined and have no abrupt changes at x = 0 in order for the product function to be continuous. If one of the functions is undefined or has a sudden change at x = 0, then h(x) will also have an abrupt change at x = 0, making it discontinuous.
To further explain, when evaluating the product of two functions at x = 0, h(x) = f(x) g(x) = f(0) g(0). For h(x) to be continuous at x = 0, it must be the case that both f(0) and g(0) exist and are defined. Thus, both f(x) and g(x) must be continuous at x = 0.

Step-by-step explanation:

To calculate this probability, we need to use the cumulative binomial probability formula:

P(X ≤ k) = Σ(i=0 to k) (n choose i) p^i (1-p)^(n-i)

Where:
- X is the number of heads obtained
- k is the number of heads we want to calculate the probability for (in this case, the same number of heads obtained)
- n is the total number of coin flips (10 in this case)
- p is the probability of getting heads on a single flip (0.5 for a fair coin)
- (n choose i) is the binomial coefficient, which represents the number of ways to choose i heads out of n flips

For this problem, we want to calculate P(X ≤ 10), since we're interested in the probability of obtaining as many heads as we did or less. Plugging in the values, we get:

P(X ≤ 10) = Σ(i=0 to 10) (10 choose i) 0.5^i 0.5^(10-i)
          = (10 choose 0) 0.5^0 0.5^10 + (10 choose 1) 0.5^1 0.5^9 + ... + (10 choose 10) 0.5^10 0.5^0
          = 0.00098 + 0.00977 + 0.04395 + 0.11719 + 0.20508 + 0.24609 + 0.20508 + 0.11719 + 0.04395 + 0.00977 + 0.00098

The Maclaurin series for f(x) converges absolutely for x within the interval (-2/3, 2/3).

To find the Maclaurin series for the function f(x) = (3cos(x))ln(1+x), we can use the standard formulas for the Maclaurin series expansion of elementary functions.

First, let's find the derivatives of f(x) up to the third order:

f(x) = (3cos(x))ln(1+x)

f'(x) = -3sin(x)ln(1+x) + (3cos(x))/(1+x)

f''(x) = -3cos(x)ln(1+x) - (6sin(x))/(1+x) + (3sin(x))/(1+x)² - (3cos(x))/(1+x)²

f'''(x) = 3sin(x)ln(1+x) - (9cos(x))/(1+x) + (18sin(x))/(1+x)² - (12sin(x))/(1+x)³ + (12cos(x))/(1+x)² - (3cos(x))/(1+x)³

Next, we evaluate these derivatives at x = 0 to find the coefficients of the Maclaurin series:

f(0) = (3cos(0))ln(1+0) = 0

f'(0) = -3sin(0)ln(1+0) + (3cos(0))/(1+0) = 3

f''(0) = -3cos(0)ln(1+0) - (6sin(0))/(1+0) + (3sin(0))/(1+0)² - (3cos(0))/(1+0)² = -3

f'''(0) = 3sin(0)ln(1+0) - (9cos(0))/(1+0) + (18sin(0))/(1+0)² - (12sin(0))/(1+0)³ + (12cos(0))/(1+0)² - (3cos(0))/(1+0)³ = -9

Now we can write the first three nonzero terms of the Maclaurin series:

f(x) = f(0) + f'(0)x + (f''(0)/2!)x² + (f'''(0)/3!)x³ + ...

f(x) = 0 + 3x - (3/2)x² - (9/6)x³ + ...

Simplifying, we have:

f(x) = 3x - (3/2)x² - (3/2)x³ + ...

To determine the values of x for which the series converges absolutely, we need to find the interval of convergence. In this case, we can use the ratio test:

Let aₙ be the nth term of the series.

|r| = lim(n->infinity) |a_(n+1)/aₙ|

= lim(n->infinity) |(3/2)(xⁿ+1)/(xⁿ)|

= lim(n->infinity) |(3/2)x|

For the series to converge absolutely, we need |r| < 1:

|(3/2)x| < 1

|x| < 2/3

0=x^2+6x+13

Step 1: Subtract x^2 from both sides.

0−x^2=x^2+6x+13−x^2

−x^2=6x+13

Step 2: Subtract 6x from both sides.

−x^2−6x=6x+13−6x

−x^2−6x=13

Step 3: Since the coefficient of -x^2 is -1, divide both sides by -1.

−x^2−6x/−1 = 13/−1

x^2+6x=−13

Step 4: The coefficient of 6x is 6. Let b=6.

Then we need to add (b/2)^2=9 to both sides to complete the square.

Add 9 to both sides.

By algebra properties and trigonometric formulas, the roots x₁ = 30° + n · 360° and x₂ = 210° + n · 360° are solutions of trigonometric function tan x - √(1 - 2 · tan² x) = 0. (Correct choice: B)

In this problem we find a given trigonometric function, whose solution must be found by combining algebra properties and trigonometric formulas. First, write the entire expression:

tan x - √(1 - 2 · tan² x) = 0

Second, use algebra and root properties:

tan x = √(1 - 2 · tan² x)

tan² x = 1 - 2 · tan² x

3 · tan² x = 1

Third, clear x by algebra properties and inverse trigonometric properties:

tan² x = 1 / 3

tan x = √(1 / 3)

tan x = 1 / √3

tan x = √3 / 3

x = tan⁻¹ (√3 / 3)

x  = 30° or x = 210°

Since tangent function has a period of 2π (360°), then the solutions of the trigonometric function is:

x₁ = 30° + n · 360°, x₂ = 210° + n · 360°.
