i edited the answer. hope it helps. if it isn't ryt tell me plz
Answer:
sin2x = [tex]\frac{30}{34}[/tex]
Step-by-step explanation:
Given
tanx = [tex]\frac{3}{5}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
This is a right triangle with legs 3 and 5
Let the hypotenuse be h , then using Pythagoras' identity
h² = 3² + 5² = 9 + 25 = 34 ( take the square root of both sides )
h = [tex]\sqrt{34}[/tex]
Thus
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]
cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{5}{\sqrt{34} }[/tex]
Hence
sin2x = 2sinxcosx = 2 × [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{5}{\sqrt{34} }[/tex] = [tex]\frac{2(3)(5)}{\sqrt{34}(\sqrt{34}) }[/tex] = [tex]\frac{30}{34}[/tex]

Step-by-step explanation:
A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its release is modeled by y = − 16 t 2 − 2 t + 400 . How long will it take for the water to reach the ground? Round to one number after the decimal point.
Answer:
4.93 seconds
Step-by-step explanation:
The height y in feet of water t seconds after its release is given by the equation as follows :
[tex]y=-16t^2-2t+400[/tex]
We need to find the taken taken for the water to reach the ground. When it reach the ground, y will be equal to 0. So,
[tex]-16t^2-2t+400=0[/tex]
Above is a quadratic equation whose solutions can be calculated as follows :
[tex]t=\dfrac{-(-2)\pm \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=\dfrac{-(-2)+ \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}, \dfrac{-(-2)- \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=-5.062\ s\ \text{and}\ 4.93\ s[/tex]
Neglecting negative value.
Hence, it will take 4.93 seconds for the water to reach the ground

Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?
Answer:
96 miles
Step-by-step explanation:
The distance from the amusement to jack's home is x (mile, x>0)
jack's family went to the amusement park at: 9 + x/60
On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph
they left the amusement park at: 20 - x/40
have the following equation:
(20 - x/40) - (9+ x/60) = 7
⇔ 4 = x/40 + x/60
⇔ x = 96
so the distance from the amusement park to jack's home is 96 miles

I promise this the last one but how do you do these type of problems?
Answer:
0.96 + 0.43v
Step-by-step explanation:
You simplify, v and -0.57v are like terms, therefore you can add them together
v - 0.57v = 0.43 v
Answer:
0.96 + 0.43v
Step-by-step explanation:
What you are doing is combining like terms. Let's say v is candy I have v - .57v that means I have one candy and I ate .57 of it already so we subtract to get .43v and the .96 is brussel sprouts. We do NOT want to mix the candy and the brussel sprouts because they are different things.
If you need me to explain more let me know, but hopefully this helps and have a great day!

2x/3+x/2=5/6
Please solve for x as a fraction!
Answer:
the value of x is 5/7 which is in fraction
Answer: x = 5/7
Step-by-step explanation: 2x/3 + x/2 =5/6
To use a least common denominator, divide LCD by the original denominator and multiply the original numerator by the result.
for 2x/3 6÷3=2 2×2x=4x so that becomes 4x/6
for x/2 6÷2=3 3× (invisible) 1 = 3x, so that becomes 3x/6
combine 4x/6 + 3x/6 = 7x/6
Back to the original equation, substituting the calculated term:
7x/6 = 5/6 Multiply both sides by 6 to simplify (6)(7x/6) = (6)(5/6) 6's "cancel"
7x = 5 . Divide both sides by 7 to solve for x 7x/7 = 5/7
x = 5/7
For field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each how much was spent on sandwiches
Answer: 216.2 + 48.75 = 264.95
Step-by-step explanation:
Multiply the amount of sandwiches by the cost.
47 * 4.60 = 216.2
Multiply the amount of chips by the cost.
39 * 1.25 = 48.75
Add them the totals together.
216.2 + 48.75 = 264.95
