Answer:
12^2 + 43x + 35
Step-by-step explanation:
(3x+7)(4x+5)
=(3x+7)(4x+5)
=(3x)(4x)+(3x)(5)+(7)(4x)+(7)(5)
=12x2+15x+28x+35
=12x2+43x+35
Answer:
Step-by-step explanation:
Given that, a series of triangle,
For the sine and cosine to be equal, then,
Sinθ = Cosθ
From, trigonometry identities
Sinθ = Cos(90-θ)
Then,
θ = 90-θ
θ + θ = 90
2θ = 90
θ = 90 / 2
θ = 45°
From the triangle given, using trigonometry ratio,
Sinθ = opposite / hypotenuse.
Sinθ = 20 / 25
Sinθ = 0.8
θ = arcsin(0.8)
θ = 53.13°
The other angles at the triangle is
90-53.13 = 36.87°.
Answer: The amount of water is 4200 liters during the first 30 minutes.
Step-by-step explanation:
Since we have given that
Water flows at the rate of
liters per minute.
Here, t is the number of minutes
We need to find the amount of water that flows from the tank during the first 30 minutes.
So, t = 30.
So, our equation becomes,
Hence, the amount of water is 4200 liters during the first 30 minutes.
2×2×10=40.
2×4×5=40.
1×5×8=40 there are so many answer.
