Seca(1-sina)(seca+tana)=1
Left hand side
=(1-sina) (seca +tana) / cosa
=seca +tana - sinaseca - sinatan / cosa
=seca + tana -tana -(sin^2a/cosa) / cosa
=(1/cosa - sin^2a/cosa) / cosa
= (1-sin^2a / cosa) / cosa
= (1-sin^2a)/ (cos^2a)
=1 (verified)
we use the rectangle rule
96-92=4 parts of 92 octane
98-96=2 parts of 98 octane
4x+2x=12
6x=12
x=2
4x=8 liters of 92 octane
2x=4 liters of 98 octane
The squares length is increasing by 5.33 cm/ s
Answer:
To what?
Step-by-step explanation:
Answer:
$5333.33
Step-by-step explanation:
x is the unknown, but we know that 22.5% of x equals 1,200. So we use this information to set up an equation.
x * 22.5% = 1,200
Now we can solve for x by dividing both sides by 22.5%
x = 5333.33
The dollar value of the items she sold was $5333.33
