Answer:

The length of segment AB is 5.

Step-by-step explanation:

If you use the Pythagorean theorem, you would find that the answer is 5.

One side of the triangle is a length of 4. The last side is a length of 3.

a^2+b^2=c^2

4^2+3^2=c^2

16+9=25

The square root of 25 is 5.

As θ increases from -pi/2 to 0 radians, the value of cos θ will.
GrogVix [38]

Answer:

4) Increase from 0 to 1

Step-by-step explanation:

We have to analyze the value of cos(Ф) from -π/2 to 0. This can be done if we simplify evaluate the value of cos(Ф) at these two extreme.

cos(-\frac{\pi}{2}) = cos(\frac{\pi}{2} )=cos(90)=0\\\\  cos(0)=1

This shows that value of cos(Ф) is 0 at  -π/2  or -90 degrees and increased to 0 at 0 degrees.

This answer can be validated if you visualize the graph of cos function. Cos function has a peak at 0 degrees, i.e. a value equal to 1. On right and left side of 0 degrees, the curve starts falling down and eventually touches the horizontal axis at 90 degrees and -90 degrees. This is shown in the graph attached below:

Theresa Morgan, a chemist, has a 30% hydrochloric acid solution and a 50% hydrochloric acid solution. How many liters of each sh
Bogdan [553]
Let x represent the number of liters of 50% acid Theresa puts into the mix. The the number of liters of 30% acid will be (420-x). The total amount of acid in the final solution will be ...
  0.50x + 0.30(420-x) = 0.45(420)
  0.20x + 126 = 189 . . . . . . . . . . . . . . . simplify
  0.20x = 63 . . . . . . . . . . . . . . . . . . . . . subtract 126
  x = 63/0.20 = 315 . . . . . . . . . . . . . . . liters of 50% solution
  (420-x) = 420-315 = 105 . . . . . . . . . liters of 30% solution

Theresa should mix ...
  105 liters of 30% solution
  315 liters of 50% solution
