What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The value of sin C will be

sin C = 3 / 5

The value of sin D will be

sin D = 4 / 5

The value of cos C will be

cos C = 4 / 5

The value of cos D will be

cos D = 3 / 5

The value of tan C will be

tan C = 3 / 4

The value of tan D will be

tan D = 4 / 3

The product of sin D and cos D will be

sin D × cos D = (4 / 5) × (3 / 5)

sin D × cos D = 12 / 25

The product of tan C and tan D will be

tan C × tan D = (3 / 4) × (4 / 3)

tan C × tan D = 1

The product of cos C and tan D will be

cos C × tan D = (4 / 5) × (4 / 3)

cos C × tan D = 16 / 15

Then the matching will be given below.

12/25 = sin D × cos D3/5 = sin D16/15 = cos C × tan D4/5 = sin C

An experiment involves selecting a random sample of 256 middle managers for study. One item of interest is their annual incomes. The sample mean is computed to be $35,420.00. If the population standard deviation is $2,450.00, what is the standard error of the mean

Answers

Answer:

the standard error is 153.125

Step-by-step explanation:

given that

The random sample is 256

The sample mean is $35,420

And, the standard deviation is $2,450

We need to find out the standard error

We know that

= standard deviation ÷ √random sample

= 2450 ÷ √256

= 2450 ÷ 16

= 153.125

Hence, the standard error is 153.125

find the slope of the line through each pair of points (19,-2) (-11,10)

Answers

Answer:

[tex]\huge\boxed{-\frac{2}{5}}[/tex]

Step-by-step explanation:

The slope of a line can be determined from two points via the slope formula. This is usually defined as the change in y divided by the change in x. It’s commonly represented using this formula:

[tex]\displaystyle \frac{\Delta y}{\Delta x}[/tex]

Where [tex]\Delta[/tex] represents “change in.”

The slope is basically just saying the rate of increase/decrease a function has when x increases by 1 - how much does y change when x increases by 1? We can find this by taking larger values and dividing by the rate at which we took the larger values. This derives the slope formula.

We can find the change in y and x in this function by analyzing the two points given. If we look at the change between each point, we can get the change since this is a line and thus has a constant slope.

The change in y will be 12. This is because from -2 to 10 is 10 units - [tex]10 - (-2) = 12[/tex] The change in x will be -30. This is because from 19 to -11 is -30 units - [tex]-19 -11 = -30[/tex]

Now that we have our change in x and y, we can substitute these values into the slope formula.

[tex]\displaystyle \frac{\Delta y}{\Delta x}[/tex] [tex]\displaystyle \frac{12}{-30}[/tex] [tex]\displaystyle -\frac{12}{30}[/tex] Simplify - divide numerator and denominator by 6 [tex]\displaystyle -\frac{2}{5}[/tex]

Therefore, the slope of this line is [tex]-\frac{2}{5}[/tex].

Hope this helped!

Step-by-step explanation:

given the system of equations, what is the value of the system to determinant.

x + y = 8

x + y = 10

This can be written in the form AX = b

A is a 2 by 2 matrices

b is a column matrix

Taking the determinant of A

[tex]A =\left[\begin{array}{ccc}1&1\\1&1\\\end{array}\right][/tex]

Answer:

f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)

Step-by-step explanation:

The zeros of the function are written in the form

f(x) = (x-a)(x-b)..... where the a,b  are the zeros

f(x) = (x-1) (x-8) (x - -7)(x-5) ( x--4)
