Answer:

To find the lowest common multiple (LCM) of 1080, 1188, and 1815, we need to find the smallest number that is a multiple of all three numbers.

One way to find the LCM is to use prime factorization. We can prime factorize each number and then multiply the highest exponent of each prime factor to get the LCM.

1080 = 2^4 * 3^3

1188 = 2^2 * 3 * 199

1815 = 5 * 11 * 163

The LCM is:

2^4 * 3^3 * 5 * 11 * 163 = 1080 * 11 * 163

So the LCM of 1080, 1188, 1815 is 207940.

Drake uses 9/4 cup of sugar to make 9 mug of brownie. Then the amount of sugar needed to make one brownie is 1/4 cup of sugar.

Determine how much sugar is needed

These are the specified parameters:

9/4 cup of sugar to make 9 mug of brownie.

Determine much sugar to make one brownie

Lots of sugar = cup of sugar : mug of brownie

                      = 9/4 : 9

Answer:

[tex]m\angle A = 44\textdegree, a = 13.9, b = 18.0[/tex]

Step-by-step explanation:

Step 1: Solve for the Missing Angle

The measures of all of the interior angles of a triangle will always add up to [tex]180\textdegree[/tex]. Therefore,

[tex]m\angle A = 180\textdegree - (m\angle B + m\angle C) = 180\textdegree - (64\textdegree + 72\textdegree) = 44\textdegree[/tex]

Step 2: Solve for the Missing Sides

When we are given the side lengths and angle measures of a triangle, we can use either the Law of Sines or the Law of Cosines to solve for the rest of the triangle.

The Law of Sines is as follows: [tex]\frac{sinA}{a} = \frac{sinB}{b} = \frac{sinC}{c}[/tex]

The Law of Cosines is as follows: [tex]c^{2} = a^{2} +b^{2} -2abcosC[/tex] (you can exchange c for a or b, respectively)

In this case, we are only given 1 side length and all 3 angle measures, so it would be more appropriate to use the Law of Sines as we need at least 2 side lengths to use the Law of Cosines.

Now that we know which formula to use, let's start by solving for [tex]a[/tex], using the given values of [tex]c=19[/tex], [tex]\angle A = 44\textdegree[/tex], and [tex]\angle C = 72\textdegree[/tex].

Substituting these values in, we get:

[tex]\frac{sinA}{a} = \frac{sinC}{c} \\ \frac{sin44\textdegree}{a} = \frac{sin72\textdegree}{19}\\a=\frac{19sin44\textdegree}{sin72\textdegree} \approx \bf 13.9[/tex]

Repeating this process for [tex]b[/tex], this time using [tex]\angle B = 64\textdegree[/tex], we get:

[tex]\frac{sinB}{b} = \frac{sinC}{c} \\ \frac{sin64\textdegree}{b} = \frac{sin72\textdegree}{19}\\b=\frac{19sin64\textdegree}{sin72\textdegree} \approx \bf 18.0[/tex]

Answer:

The equation 2n + 1 = 157 represents the situation where the sum of two consecutive numbers is 157.

To find the first number, we can start by subtracting 1 from both sides of the equation:

2n = 156

Then we can divide both sides by 2:

n = 78

So the first number is 78, which corresponds to the answer choice B.

Step-by-step explanation:

The function F(x) has a derivative f'(x) = sin(x) - xcos (x). This is accomplished by employing the chain rule and the basic calculus theorem.

The calculus fundamental theorem can be used to derive the derivative of f(x).

Let x1sin(t)dt equal F(x). The fundamental theorem of calculus states that F'(x) = sin (x).

Let g(x) now equal x. The chain rule then states that f'(x) = g' (x) F'(x)= g'(x)sin(x)=cos (x).

Therefore, f'(x) = sin(x) - xcos is the derivative of f(x) (x).

F(x) has a derivative f'(x) = sin(x) - xcos (x). Applying the chain rule and the calculus's fundamental theorem will get this result. The integrand assessed at the integral's upper limit is equivalent to the derivative of a definite integral, according to the calculus fundamental theorem. According to the chain rule, the derivative of a function made up of two functions is equal to the sum of the derivatives of the inner and outer functions. The inner function in this instance is sin(t), while the outer function is x. Thus, by using the chain rule and the fundamental theorem of calculus, we can determine that f'(x) = sin(x) - xcos (x)

Answer:

z ≈ 12.2 cm

Step-by-step explanation:

using Pythagoras' identity in the 2 right triangles.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

consider the right triangle on the left

let the third side, the hypotenuse be x , then

x² = 5² + 15² = 25 + 225 = 250

consider the right triangle on the right , then

x² + z² = 20²

250 + z² = 400 ( subtract 250 from both sides )

z² = 150 ( take square root of both sides )

z = [tex]\sqrt{150}[/tex] ≈ 12.2 cm ( to 1 decimal place )

The lowest term of rational expression is 4z⁶/3

What is rational expression?

A rational expression is simply a quotient of two polynomials. Or in other words, it is a fraction whose numerator and denominator are polynomials.

Rational expressions look like fractions that have variables in their denominators (and often numerators too). For example, x 2 x + 3 \dfrac{x^2}{x+3} x+3x2 ​start fraction, x, squared, divided by, x, plus, 3, end fraction is a rational expression.

To write a rational expression in lowest terms, we must first find all common factors (constants, variables, or polynomials) or the numerator and the denominator. Thus, we must factor the numerator and the denominator. Once the numerator and the denominator have been factored, cross out any common factors.

A) The expression is undefined when x=10 or x=-5 because the denominator would be equal to zero, which is undefined in mathematics.

B) The rational expression 8z³/20z⁶ can be simplified to 2z³/5z⁶. The expression can be further simplified by dividing both the numerator and denominator by z³, giving us 2/5z³.

C) The expression 12-4/5y-36 is undefined when y=-9 or y=4 because the denominator would be equal to zero, which is undefined in mathematics.

D) The expression (99-3333)/2535 cannot be simplified as the numerator and denominator are prime numbers and cannot be further reduced.

To compute the median of three sets of scores, we need to arrange the scores in order from smallest to largest and then select the middle score.

Mean, median and mode are measures of central tendency and are used to describe the central value of a set of data. The mean is the average of all the values in the set, the median is the middle value and the mode is the most frequently occurring value.

To compute the mean of three sets of scores, we need to sum up all the scores and divide by the total number of scores. This can be represented by the formula:

Mean = (Score1 + Score2 + Score3) / 3

To compute the median of three sets of scores, we need to arrange the scores in order from smallest to largest and then select the middle score. This can be represented by the formula:

Median = (Score2 + Score3) / 2

To compute the mode of three sets of scores, we need to identify the score that occurs the most frequently. This can be represented by the formula:

Mode = Most Frequently Occurring Score

The washer method is a way to calculate the volume of a solid that is created when a region is rotated about a certain line.

Here you find the area of this cross section, and multiply it by the circumference of a circle with the same radius as the cross section.

To use the washer method to find the volume of the solid created when the region bounded by

we first need to find the cross section of the solid at different heights along the line of rotation.

To do this, we need to find the points where the plane perpendicular to the line of rotation intersects the original region. This is done by finding where the equation of the plane and the equation of the original region intersect.

Next, we find the area of the cross section and multiply it by the circumference of a circle with the same radius.
