300 represents the initial amount of the substance, the amount present at t=0.

0.5 is the fraction of substance remaining at the end of each year. The fact that this number is 1/2 indicates the half-life of the substance is 1 year.

WZ and XR are diameters what is thr measure of ZWX?
castortr0y [4]

Answer:

mZWX = 214°

Step-by-step explanation:

In a circle C, XR and WZ are two diameters.

∠ XCW = 34° and ∠ YCZ = 86°

We have to find the measure of arc ZWX

Since ∠XCW + ∠XCY + ∠YCZ = 180° [ angles on a straight line ]

34° + ∠XCY + 86° = 180°

120° + ∠XCY = 180°

∠XCY = 180 - 120 = 60°

Now arc ZWX = 360° - (∠XCY + ∠ YCZ)

                       = 360° - (60° + 86°)

                       = 360° - 146°

                       = 214°

Therefore answer is arc ZWX = 214°

True or false and why: if a and b are irrational, then a^b is irrational
FrozenT [24]

False


b could be the logarithm of a rational number to the base a. For example,

b=\log_\pi{(4)}   will be irrational, but π^b = 4, a rational number
