Hello :
<span>1) 1- cos²Θ ≡ sin²Θ
</span>cos²Θ + sin²Θ = 1
sin²Θ = 1- cos²Θ
<span>
2) (1-sin²Θ) tanΘ≡ cosΘ sinΘ
by 1) :
</span>1-sin²Θ =cos²Θ
cos²Θ × tanΘ = cos²Θ × (sinΘ)/(cosΘ) =cosΘ sinΘ
Answer:
45
Step-by-step explanation:
the left and right side are symetrical
Derive the system of linear equations from the given above,
y = mx + b
From the given,
110 = m(2) + b
220 = m(4) + b
From the system, the value of m is equal to 55 and b is equal to 0. Therefore, after 5 hours, the car travels (55 m/s) x 5 s = 275 meters.
1/4 divided by 7/1 equals 1/28
