Alex787 [66]3 years ago
6 0

Answer:

Step-by-step explanation:

we have

cscx = sinx tanx + cosx\\\\\frac{1}{sinx}=sinx.\frac{sinx}{cosx} +cosx\\\\\frac{1}{sinx}.sinx.cosx= sinx.\frac{sinx}{cosx}.sinx.cosx+cosx.sinx.cosx\\  cosx= (sinx)^{3} +sinx.(cosx)^{2} \\cosx= sinx[(sinx)^{2}+(cosx)^{2})\\  cosx=sinx.1\\cosx=sinx\\tanx=1\\x=\frac{\pi}{4} +k\pi,k-integer.

You can draw a quadrilateral with two sets of parallel lines and no right angles?
bonufazy [111]
Yes you can. The quadrilateral that you would get is called parallelogram. It has 2 paris of parallel lines. and 2 pairs of equal angles. one pair is angles that are less than 90 degrees and other one is where 2 angles are greater than 90 degrees each. Therefore there isnt any right angle there and you got yourself quadrilateral. of these 2 parallel lines are of equal lenght than you get something called rhombus.

Answer:

\text{D. }b^2-4ac>0

Step-by-step explanation:

The equation b^2-4ac represents the discriminant of a quadratic. It is the part taken from under the radical in the quadratic formula.

For any quadratic:

  • If the discriminant is positive, or greater than 0, the quadratic has two solutions
  • If the discriminant is equal to 0, the quadratic has one distinct real solution (the solution is repeated).
  • If the discriminant is negative, or less than 0, the quadratic has zero solutions

In the graph, we see that the equation intersects the x-axis at two distinct points. Therefore, the quadratic has two solutions and the discriminant must be positive. Thus, we have b^2-4ac>0.

Would be great if someone explained this
sasho [114]

A. 2.

A radical is an expression which implies the use of a root.

There are three components of a radical expression:

(i) The root "√".

(ii) The radicand √"a".

(iii) The degree or index of the radical \sqrt["n"]{a}, when index of the radical is not shown then it understood to be a index of 2.

The index is the number used to indicate the degree of the root.

For the example \sqrt{10}, 10 is the radican and the index is not shown so it understood is 2.
