Answer:
Here you go
Step-by-step explanation:
The quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math. Then the formula will help you find the roots of a quadratic equation, i.e. the values of x where this equation is solved.
Answer:
A 1/3
Step-by-step explanation:
Change fraction into a decimal
1/4=0.25
1/12=0.83
0.83 divided by 0.25=0.33
1/3=0.3, so 1/3 is the answe
Okay, there is a right angle so that equals 90. A given angle inside the triangle is 35. To find the missing angel within the triangle you do 90+35 which will give you 125. You will then subtract 125 from 180 ( because all triangles add up to 180 ) so the angle missing at the top would be 55. Now, you’re going to want to use Sine, Cosine, and Tangent. I would use the angel 35 that they provided you. So the way you set it up will be -
Tan (35) = x / 12
Then you’re going to want to cross multiply so you will now have
X = tan(35) • 12
^ plug this equation into a calculator and you will get your answer. I hope this helped!
Bear in mind that, when it comes to trigonometric functions, the location of the exponent can be a bit misleading, however recall that sin²(θ) is really [ sin( θ )]²,
![\bf 2sin^2(2x)=2\implies sin^2(2x)=\cfrac{2}{2} \\\\\\ sin^2(2x)=1\implies [sin(2x)]^2=1\implies sin(2x)=\pm\sqrt{1} \\\\\\ sin(2x)=\pm 1\implies sin^{-1}[sin(2x)]=sin^{-1}(\pm 1)](https://tex.z-dn.net/?f=%5Cbf%202sin%5E2%282x%29%3D2%5Cimplies%20sin%5E2%282x%29%3D%5Ccfrac%7B2%7D%7B2%7D%0A%5C%5C%5C%5C%5C%5C%0Asin%5E2%282x%29%3D1%5Cimplies%20%5Bsin%282x%29%5D%5E2%3D1%5Cimplies%20sin%282x%29%3D%5Cpm%5Csqrt%7B1%7D%0A%5C%5C%5C%5C%5C%5C%0Asin%282x%29%3D%5Cpm%201%5Cimplies%20sin%5E%7B-1%7D%5Bsin%282x%29%5D%3Dsin%5E%7B-1%7D%28%5Cpm%201%29)
