Answer:
a=3√2, c= [tex]\frac{3\sqrt{2}}{2}[/tex]
Step-by-step explanation:
First Triangle, this is a 45-45-90 triangle
so the side are 1-1-√2
so if one of the side is 3, you multiply the above by 3
1*3-1*3-√2*3
therefore, a=3√2
Second triangle
this is a 30-60-90 Triangle
so the sides are x-x√2-2x
for this triangle
x√2=6
x=6/√2 --> multiply by √2/√2 --> this gets ride of the √2 in the denominator
x=6√2/4 --> simplify
x=[tex]\frac{3\sqrt{2}}{2}[/tex]
therefore, c=[tex]\frac{3\sqrt{2}}{2}[/tex]

Take out C immediately, as the distance is 100% not more than 3 units.
I'm going to go with the premise that wherever the letters' points on the graphs are where the letters are located.
Take out D as well because the distance is around 2 - 2.66 units, and not under (Look at what I said previously).
Now if we get a ruler and rotate it exactly to the line from D to E, we will get the answer B (This is due to angles).

A helicopter floats 120m above a helipad, a dog is 85m from the helipad, if the dog could fly, how far would it have to fly to get to helicopter?
Answers
If the dog could fly, it would need to fly 147 meters to catch the helicopter
This is a rather easy and straightforward question. We are going to solve it using Pythagoras theorem. We can interpret the question to be in a triangle where the height of the helicopter above the helipad and away from the dog is the right angle. This also means that the distance needed, between the dog and the helicopter is the hypotenuse.
Using pythagoras theorem, we have
120² + 85² = c²
c² = 14400 + 7225
c² = 21625
c = [tex]\sqrt{21625}[/tex]
c = ±147 meters.
Since distance cant be in the negative, our answer is 147 m

Answer:
F=(9C+160)/5
Step-by-step explanation:
C=5(F-32)/9
Simplify to 5F-160/9=c
multiply by 9 on both sides : 5F-160=9C
add 160 to both sides: 5F=9C+160
Divide by 5 on both sides: F=(9C+160)/5
Simplify: F=9/5c+32
Answer:
[tex]F=\frac{9C}{5}+32[/tex]
Step-by-step explanation:
The subject of the formula is the variable that's being worked out. Originally this was C. They want us to make F the subject of the formula.
[tex]c=\frac{5(F-32)}{9}[/tex]
To do this we first need to distribute 5.
[tex]C=\frac{5F-160}{9}[/tex]
Divide 5F-160 by 9.
[tex]C=\frac{5}{9}f-\frac{160}{9}[/tex]
We can then swap sides to make it easier.
[tex]\frac{5}{9}f-\frac{160}{9}=C[/tex]
We then add [tex]\frac{160}{9}[/tex] to each side.
[tex]\frac{5}{9}f=c+\frac{160}{9}[/tex]
We can then find F by multiplying by 9/5 or dividing by 5/9.
[tex]F=\frac{9}{5}(C+160/9)[/tex]
We then can simplify by multiplying.
[tex]F=\frac{9C}{5}+32[/tex]

Find the perimeter. Simplify your answer.
Answers
Answer:
6z-30 :D
Step-by-step explanation:
The perimeter of a square is just all the sides added up together. To do this we can make an equation.
2(z-5) + 2(2z - 10)
This represents two sides with different lengths two times. To solve, you first use the distributive property to multiply z-5 by 2.
2z - 10 + 2(2z - 10)
We then use the distributive property by multiplying 2z - 10 by 2.
2z − 10 + 4z − 20
We then combine 2z and 4z to get 6z.
6z − 10 − 20
Subtract 20 from 10 to get -30.
6z-30.
Answer:
6z - 30Step-by-step explanation:
Perimeter = z - 5 + z - 5 + 2z - 10 + 2z - 10

Hope it Helps you!!Two boats leave the same port at the same time. One travels at a speed of 28 mi/h in the direction N 50° E, and the other travels at a speed of 26 mi/h in a direction S 70° E (see the figure). How far apart are the two boats after 1 h? (Round your answer to the nearest mile.)
Answers
Answer:
27 miles
Step-by-step explanation:
The law of cosines can be used to find the distance between the boats. In 1 hour, one has traveled 28 miles, and the other has traveled 26 miles. The angle between their directions of travel is ...
180° -50° -70° = 60°
Then the distance c can be found from ...
c^2 = a^2 +b^2 -2ab·cos(C)
c^2 = 28^2 +26^2 -2·28·26·cos(60°) = 732
c = √732 ≈ 27.055
The boats are 27 miles apart after 1 hour.

= (4x² + 5x)(4x² +5x -6) +1 (4x² +5x -6)
= (4x²+5x-6)(4x²+5x+1)
= (4x² + 8x - 3x - 6)(4x² + 4x + x +1)
