So you can solve this using the equation (y2 - y1)/(x2 - x1). This basically means the difference of the y-values (rise) divided (over) the difference of the x-values (run). So basically, this equation is used to find the “rise over run.” In this case, I’ll choose the coordinate pair (0,2) to be my first values, and (4,5) to be my second. Doing it vice versa wouldn’t affect the outcome since both the numerator and denominator would come out to be negative, and a negative divided by a negative is a positive. To solve this, plug in the values to get (5 - 2)/(4 - 0). This reduces to 3/4. To find the slope of the perpendicular line, you would do the opposite reciprocal of that. This means that you would flip the numerator and denominator and change the positive/negative sign to the opposite one of what it is. So the final answer will be -4/3. Hope this helps! Don’t mind my lengthy answers!

Answer:

d) 135º

Step-by-step explanation:

Note that the angle DCU is the sum of the angles DCB and BCU. The angle DCB is 90º because A B C D is a square, then all its angles are equal to 90º.

After attaching B U C to A B C D, we obtain a trapezoid A U C D. Since A U C D has at least one pair of parallel sides, then AU should be parallel to CD, thus the angle CBU must be 90º.

B U C is isoceles, so we conclude that other two angles must have the same size, and due to the sum of the angles of a triangle being 180º, then both BUC and BCU are equal to 45º

As a result, the angle DCU is equal to 90º+45º = 135º. Option d is the correct one.

Rolling a 3 or rolling an odd number on a six sided die. Is it mutually exclusive or non-mutually exclusive? Give one reason.

Cerrena [4.2K]

Answer:

Non-mutually exclusive

Step-by-step explanation:

both events can happen simultaneously... 3 is an odd number, events A and B have a common outcome.

It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes. 2x+3y=6

sweet-ann [11.9K]

Answer:

x-intercept: (3, 0)

y-intercept: (0, 2)

Step-by-step explanation:

For a function like:

y = f(x)

The x-intercept is the value of x when y = 0

the y-intercept is the value of y when x = 0

Also remember that an ordered pair is written as (x, y).

In this case we have the equation:

2*x + 3*y = 6

For the x-intercept, we just replace y by zero in the equation, then we get:

2*x + 3*0 = 6

Solving this for x, we get:

2*x = 6

x = 6/2 = 3

Then in this case, the ordered pair for the x-intercept is (3, 0)

For the y-intercept, we just need to replace x by zero in the equation:

2*0 + 3*y = 6

Solving this for y, we get:

3*y = 6

y = 6/3 = 2

Then the ordered pair for the y-intercept is (0, 2)

alexdok [17]

Answer:

The bee traveled 11.7 meters.

Step-by-step explanation:

A bee flew 840 cm first to land on a flower to collect some pollen and then flew another 330 cm to get back to her hive.

For finding the total distance traveled, we need to just add 840 cm and 330 cm.

So, $(840+330) cm = 1170 cm$

We know that, 1 meter = 100 cm. That means, for converting 'cm' into 'meter' , we need to divide by 100.

Thus, $1170 cm= \frac{1170}{100} meter = 11.7 meter$

So, the bee traveled 11.7 meters.
