Answer:
129.5km
9.78° North of east
Step-by-step explanation:
Let say HQ is at the origin (x = 0, y = 0)
the coordinates of the helicopter after the 1st flight can be expressed below as
X1= -120 cos45=84.85km
Y1= -120 sin45= -84.85km
its coordinate after the 2nd flight can be expressed as
X2= x1 - 125sin20
= -84.85-42.75
=-127.6km
Y2= y1- 125cos60
=-84.5+62.5
=-22km
The distance and it's direction for it to fly back to its HQ can be calculated as
S= √(22^2 + 127.6^2 )
=129.48km
Tan θ= y2/y1
=22/127.6= 0.1724
Tan-1(0.1724)
= 9.78° North of east
Hence, the distance and direction it should fly is 129.48km and 9.78° North of east respectively

Step-by-step explanation:
The first one is the third root of 5^2. The denominator represents the root in which you're taking, in this case the third root, and the numerator represents the exponent that will be underneath the radical with the integer
The second one is the square root of 5. Anytime you see a 2 as the denominator in an exponent you're just taking the square root
The third one is the fifth root of 3^2, as explained by the first one
The fourth one is the square root of 3^5, as explained with the second one

21,28,35 determine whether the triangle is acute, right,obtuse, or not a triangle.
Answer:
I believe it is an acute triangle but im not 100% sure
Step-by-step explanation:
The triangle with sides 21 , 28 and 35 is a right angle triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle is BC = 21
The height of the triangle AB = 28
The hypotenuse of the triangle is AC = 35
And , for a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Substituting the values in the equation , we get
35² = 21² + 28²
On simplifying the equation , we get
1225 = 441 + 784
1225 = 1225
Hence , the triangle is a right angle triangle

Which expression is equivalent to 10 - 8?
Answer:
(Choice A) 10 + (-8)
Step-by-step explanation:
Which expression is equivalent to
10 - 8?
Comparing the options
(Choice A) 10 + (-8)
The rule = + × - = -
Hence
10 + (-8)
= 10 - 8
Choice A is correct
Choice B) 8-10
8 - 10, Choice B is incorrect
(Choice C) 10-(-8)
The rule states that:
- × - = +
Hence,
10 -(-8)
= 10 + 8
= 18
(Choice D) -8-10
-8 - 10
= -18
This is incorrect.
Choice A is the correct option which is the expression is equivalent to 10 - 8.

Solve for P:
9(p−4)=−18
Please Explain
Answer:
p = 2
Step-by-step explanation:
Happy to help.
When we have numbers in parenthesis, we generally want to deal with those first. However, we can hit a rough patch when a variable is in there. Consider this:
2(3 + 4) = 2(7), or 14.
But, the two can also be distributed into both numbers in the parenthesis, like this:
2(3 + 4) = 2*3 + 2*4
That leaves us with the same answer—14! We can apply this to a variable, and that will help us figure out 9(p - 4), or the left side of your equation you presented.
9(p - 4) = -18
9*p - 9*4 = -18
9p - 36 = -18
Add 36 on both sides to isolate the variable (in this case, p)
9p = -18 + 36
You can also write it like this; 9p = 36 - 18
9p = 18
Divide 9 to isolate p
p = 2
So, we would get (p = 2). Make sure to practice a few more questions like these to really get the hang of it—you'll be using this a lot in the future!
Good luck!
Pls can someone help me factorise this: a²+9a+8
Answer:
(a + 8)(a + 1)
Step-by-step explanation:
We know that the first term is squared, so we can put it out like this:
a * a
The third term has to be separated so that the sum of the two factors is the coefficient of the second term, 9.
8 = 4 * 2 (does 4 +/- 2 = 9? nope, we can't use that)
8 = 8 * 1 (does 8+/- 1 = 9? yes, when 8 + 1)
So the factor is a + 8 and a + 1.
Put this together and (a+8)(a+1)

James read an equal number of pages of his book each night for 8 nights to prepare for his upcoming exam. During this time, he has read a total of StartFraction 6 Over 7 EndFraction of the book. What fraction of the book did he read each night?
Answer:
3/28
Step-by-step explanation:
James read an equal number of pages of his book each night for 8 nights to prepare for his upcoming exam.
The total fraction of the book he read in 8 nights = 6/7
Hence,
8 nights = 6/7
1 night = x
Cross Multiply
8x = 6/7 × 1
x = 6/7 ÷ 8
x = 6/7 × 1/8
x = 3/28
Therefore, every night, the fraction of the book he has read is 3/28
