cos A = 3/5

Step-by-step explanation:

sin A = 4/5

sin^2 A + cos^2 A = 1

(4/5)^2 + cos^2 A = 1

16/25 + cos^2 A = 1

cos^2 A = 9/25

Answer:

324 minutes or 5.4 hours

Step-by-step explanation:

400/3 = 133.333

133.333/60 = 2.2222

It took him one minute to paint 2.2222 square feet

720/2.2222 = 324 minutes

324/60 = 5.4 hours

Answer:

It will take Andy 5 hours and 24 minutes to paint 720 sq. ft.

Step-by-step explanation:

Since he painted 400 sq. ft. in 3 hours, then do 400/3 to get 133.33... sq. ft per hour. Then, do 720 / 133.33... to get 5.40000000001 hours taken. The 5 represents 5 hours, and the .4 represents 24 minutes (because 60 x .4 = 24).

Overall, you get 5 hours and 24 minutes of time to pain 720 sq. ft.

To find a second solution, we can use the method of reduction of order. Let's assume a second solution of the form y2(x) = v(x) * y1(x), where y1(x) is the given solution.

First, let's calculate the derivatives of y1(x):

y1'(x) = (2/x) * x * sin(2 ln(x)) + x * cos(2 ln(x))

y1''(x) = (2/x) * cos(2 ln(x)) + (2/x) * x * cos(2 ln(x)) - 2 * sin(2 ln(x))

Substituting these derivatives into the original differential equation:

x^2 * (v(x) * y1''(x)) - x * (v(x) * y1'(x)) + 5 * (v(x) * y1(x)) = 0

Expanding and simplifying the equation:

x^2 * (v(x) * ((2/x) * cos(2 ln(x)) + (2/x) * x * cos(2 ln(x)) - 2 * sin(2 ln(x)))) - x * (v(x) * ((2/x) * x * sin(2 ln(x)) + x * cos(2 ln(x)))) + 5 * (v(x) * (x * sin(2 ln(x)))) = 0

Canceling out the common factors of v(x) and rearranging terms:

(2 * cos(2 ln(x)) + 2 * x * cos(2 ln(x)) - 2 * x * sin(2 ln(x))) - (2 * x * sin(2 ln(x)) + x * cos(2 ln(x))) + 5 * x * sin(2 ln(x)) = 0

Simplifying further:

2 * cos(2 ln(x)) + 2 * x * cos(2 ln(x)) - 2 * x * sin(2 ln(x)) - 2 * x * sin(2 ln(x)) - x * cos(2 ln(x)) + 5 * x * sin(2 ln(x)) = 0

Combining like terms:

2 * cos(2 ln(x)) + 2 * x * cos(2 ln(x)) - 4 * x * sin(2 ln(x)) - x * cos(2 ln(x)) + 5 * x * sin(2 ln(x)) = 0

Simplifying further:

(2 + 2x - x) * cos(2 ln(x)) + (5x - 4x) * sin(2 ln(x)) = 0

Simplifying even more:

x * cos(2 ln(x)) + x * sin(2 ln(x)) = 0

Dividing by x:

cos(2 ln(x)) + sin(2 ln(x)) = 0

At this point, we have obtained an equation that does not depend on v(x) anymore. We can solve this equation separately to find the values of x that satisfy it.

cos(2 ln(x)) + sin(2 ln(x)) = 0

Using the trigonometric identity sin(x) + cos(x) = 0, we can equate 2 ln(x) to π/4, 5π/4, 9π/4, etc. to find the solutions for x.

2 ln(x) = π/4 + 2kπ, 5π/4 + 2kπ, 9π/4 + 2kπ, where k is an integer

ln(x) = π/8 + kπ/2, 5π/8 + k

The number of toy soldiers that Leo has is 48.

The first step is to determine the multiples of 4 that lie between 27 and 54. A multiple of a number is the product of an integer and that number.

Multiplies of 4 that lie between 27 and 54 = 28, 32, 36, 40, 44, 48, 52

Now divide each of the multiples by 7 :

28 / 7 = 4

32 / 7 = 4 remainder 4

36 / 7 = 5 remainder 1

40 / 7 = 5 remainder 5

44 / 7 = 6 remainder 2

48 / 7 = 6 remainder 6

An integer can be a negative number but it can't be a decimal.

x - 2y = 2. …………(1). and x + y^2 =10. ………………(2).

Subtracting eqn. (1) from eqn. (2).

y^2 + 2y = 8.

or, y^2 +2y - 8 =0.

or, (y +4).(y-2)=0.

or, y = -4 , 2. and x = -6 , 6.

Thus, A(-6,-4) and B(6,2). let the mid point of AB is M , M((-6+6)/2,(-4+2)/2)

or, M(0, -1).

slope of AB = (2+4)/(6+6) = 1/2.

Slope of the perpendicular bisector of the line AB= -2.

Hence, the eqn. of the perpendicular bisector of AB is:-

y. +1 = - 2.(x - 0).

Answer:

(-2^6) is 64, which is positive.

Step-by-step explanation:

To write -2^6 as repeated multiplication, we can write it as (-2)(-2)(-2)(-2)(-2)*(-2). To evaluate this expression, we can compute it as follows:

(-2)(-2)(-2)(-2)(-2)(-2)

= ((-2)(-2)(-2)(-2)(-2))(-2)

= ((((-2)(-2)(-2)(-2))(-2))(-2)

= (((((-2)(-2)(-2))(-2))(-2))(-2)

= (((((-2)(-2))(-2))(-2))(-2))(-2)

= (((((-2)(-2))(-2))(-2))(-2))(-2)

= (((-2)(-2)(-2))(-2))(-2)(-2)

= (((-2)(-2)(-2))(-2))(-2)(-2)

= ((-2)(-2))(-2)(-2)(-2)(-2)

= (-2)(-2)(-2)(-2)(-2)(-2)

= 64

Therefore, the result of (-2^6) is 64, which is positive.

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

After the 10th iteration, the estimated value of the root obtained by the bisection method is approximately 0.517. Option B

To solve the equation cos(x) - x * e = 0 in the interval [0, 1] using the bisection method, we start by checking the function values at the endpoints of the interval.

For x = 0:

cos(0) - 0 * e = 1 - 0 = 1

For x = 1:

cos(1) - 1 * e ≈ 0.54 - 2.72 ≈ -2.18

Since the function values at the endpoints have opposite signs, we can apply the bisection method to find the root within the interval.

The bisection method involves repeatedly dividing the interval in half and checking the function value at the midpoint until a sufficiently accurate approximation is obtained. In this case, we will perform 10 iterations.

After the 10th iteration, the estimated value of the root obtained by the bisection method is approximately 0.517.

Therefore, the correct answer is OB) 0.517.

Answer:

c = 32

Step-by-step explanation:

90 + 58 + c = 180

90 + 58 = 148

180 - 148 = 32

c = 32

Answer:

32

Step-by-step explanation:

As we know the total degree of a triangle is 180 degrees.

In this triangle so far we have a 58 degree and 90 degree box since its a right triangle so we have to take:

58 + 90 = 148

After taking 148 we have to subtract the 180 to find the missing number that will help us complete everything:

180 - 148 = 32

Percent is a way of expressing a number as a fraction of 100. It is denoted by the symbol "%". Percentages are commonly used to express ratios, proportions, and rates. They are used in many areas of everyday life, such as in finance, business, and statistics.

Here,

The Interest Formula is:

I = P * R * T

where I is the interest earned, P is the principal (initial amount of money), R is the interest rate, and T is the time period.

We can rearrange the formula to solve for P:

P = I / (R * T)

Both descriptive and inferential statistics are important branches of statistics and serve different purposes. Descriptive statistics is used to describe and summarize data, while inferential statistics is used to make predictions and draw conclusions about a population based on a sample of the data.

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It helps in making informed decisions based on the data and provides insights into the data. There are two main branches of statistics: descriptive statistics and inferential statistics.

Descriptive statistics is used to describe and summarize the data. It involves collecting, organizing, analyzing, and interpreting data in a meaningful way. Descriptive statistics help to present the data in a way that is easy to understand and interpret. It includes measures such as mean, median, mode, and standard deviation. For example, if we have a data set of heights of students in a class, we can use descriptive statistics to find the average height of students, which will give us a better understanding of the data.Inferential statistics, on the other hand, involves making inferences and predictions about a population based on a sample of the data. It helps in drawing conclusions and making decisions about a population based on a sample. Inferential statistics uses statistical models and hypothesis testing to make predictions and draw conclusions about the population. For example, if we have a sample of 100 students from a class of 1000 students and we want to know the average height of all the students in the class, we can use inferential statistics to make an estimate based on the sample data.
