Answer:

Step-by-step explanation:
Hello,


It means that

And we know that

So we got two equations

For 
For 
I assume that we are after two different roots so the solution for p is p=-11
b) 
So a quadratic equation with the expected roots is

Answer:
262/365
Step-by-step explanation:
So as you can see there is no more information aout Kay on her birthday, so the chances of her birthday being on a week day is given by the total number of the weekdays of the year between the total number of days in a year, so in 2019 there are 262 weekdays, divided by 365 you get the probability that Kay´s birthday falls on a weekday.
262/365=,7178=71,78%
So the probability of Kay´s brithday falling on a week day will be 71,72%
Answer:
e. 72 inches
Step-by-step explanation:
Well, firstly to find the lengths of the sides, we would have to find the square root of 36 (which is 6, as 6x6=36).
Now, if we enlarge the square by SF 3, the new side lengths would be 6x3=18 inches. That is only one side.
Now we know the length of one side, we can do 18x4 (because as we all know, squares have 4 sides) to find the perimeter.
18x4=72 inches. This means the answer is option e.
I've drawn a triangle to represent the journey (see attached.
The angle from Home to Victim to Hospital is:
a =

Using the cos rule, we can solve for the length x:

Using the cos rule, we can solve for angle b:

So the bearing the helicopter has to travel is:
270 - 76.1 =
<u>
193.9 degrees (1 dp)</u>
And the distance it travels is
<u>31.2 km (1 dp)</u>
