Answer 1

Answer:

In the figure,

AC is the diameter of circle with centre O

∠DAC=37

A legal document contains pages numbered 1 through 50. What is the probability that the lawyer will flip to a page number
that is not a multiple of 4?
• Write your answer in fraction form. Reduce the fraction if necessary.
Provide your answer below:

Answers

Using it's concept, it is found that the probability that the lawyer will flip to a page number that is not a multiple of 4 is given by:

[tex]p = \frac{19}{25}[/tex]

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, there are 50 numbers, of which 50 - (48/4) = 38 are not multiples of 4, hence the probability is given by:

[tex]p = \frac{38}{50} = \frac{19}{25}[/tex]

if A=-3+5i, B=4-2i and C=1+6i, where i is imaginary unit, then A-BC equals to what?

Answers

Multiplication is the process of multiplying. The value of A-BC is equal to -19-17i.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The value of BC is,

BC = (4-2i)×(1+6i)

BC = 4 + 24i - 2i -12i²

BC = 4 + 22i - 12(-1)

BC = 4 + 22i +12

BC = 16 + 22i

Now, the value of A-BC will be equal to,

A-BC = (-3+5i)-(16+22i)

         = -3+5i-16-22i

         = -19 - 17i

Hence, the value of A-BC is equal to -19-17i.

5. Find the equation of the line that is perpendicular to the given line and passes through the given point. y = 5x-1; (-1, 1)​

Answers

Answer:

y = -0.2x+ 0.8

Step-by-step explanation:

If a line is perpendicular to another line then the slope of the line = the negative reciprocal of the other line

Here Line AB has the equation y = 5x - 1. Here slope = 5
This comes from the fact that if a line has the equation y= mx + c then the slope = m and the y intercept = c

If XY is the line perpendicular to AB then its slope = -1/5. Let the y intercept of XY be c

Then equation of line XY is: y = (-1/5)x + c = -0.2x + c (1)

Since it passes through (-1, 1) ie through x = -1, y=1, substitution these values into the above equation (1), we get

1 = (-0.2)(-1) + c or

1 = 0.2 + c or  

c = 0.8

Step-by-step explanation:

Before we start calculating we have to first note that the angles in a triangle always add up to 180°. Therefore in order to find the missing angle U we have to add both the angles we know, 37° and 63°, then subtract the sum from 180°

slope = - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + y = - 7 ( subtract x from both sides )

y = - x - 7 ← in slope- intercept form

with slope m = - 1

Parallel lines have equal slopes

Can someone help. I literally forgot this how

Answers

Answer:

Below.

Step-by-step explanation:

The 2 triangles are congruent ( By 2 angles and corresponding side).

The  2 marked angle are congruent so

5y - 30 = 2y + 6

3y = 36

y - 12.

So m < O = 5(12) - 30 = 30 degrees.

and m <N = 180 - 30 - 90 = 60 degrees,   (as there are 180degrees in triangle)

EN = IV = 14.

It is possible to find the measure of OE and ON by using trigonometry of a right triangle.

tan 30 = EN / OE

OE = EN / tan30

= 14/tan30

= 24.3.

sin 30 = 14/ON

ON = 14 / sin 30

= 28.

one last question! so i am doing this equation 6x-5=8x+2 but as I am doing it I got 7/-2 but in my answer key both are negative? what am I doing wrong?

this is what I have so far
6x-5=8x+2
6x-8x=5+2
-2x=7

Answers

Answer:

6x - 5 = 8x + 2

or -5-2 = 8x-6x

or -7 = 2x

or -7 / 2 = x

this is correct answer because in fraction form if one number is negative whole fraction is negative

Hey there!

IF YOUR EQUATION IS:

6x - 5 = 8x + 2
THEN:

SUBTRACT 8x to BOTH SIDES

6x - 5 - 8x = 8x + 2 - 8x

SIMPLIFY IT!

-2x - 5 = 2

ADD 5 to BOTH SIDES

-2x - 5 + 5 = 2 + 5

SIMPLIFY IT!
-2x = 2 + 5

-2x = 7

DIVIDE -2 to BOTH SIDES

-2x/-2 = 7/-2

SIMPLIFY IT!
x = -7/2


The step you had a partial mistake was step 2 because that’s not what had to simplify to get the 7/-2. You should’ve converted your equation to: -2x - 5 = 2 (as I put for STEP 1.1) but your overall result is correct x DOES equal to 7/-2.
