Find the lengths of the lettered angles and sides. No approximation for square root is allowed

inn [45]

Answer:

x = 30°, y = 45°
w = 14√2, v = 7√2

Step-by-step explanation:

ΔABC

BC/AB = sin x
12/24 = sin x
1/2 = sin x
x = 30°

ΔDBC

DC = BC - given
∠C = 90° - given
ΔDBC is isosceles right triangle

∠BDC ≅ ∠DBC ⇒ y = 45°

-------------------------------------------

ΔMPN is right isosceles triangle ⇒ MN = PN√2 = 14√2

w = 14√2

ΔMKP is right isosceles triangle ⇒ MK = KP

v = 1/2MN = 1/2(14√2) = 7√2

The amount of radioactive uranium changes with time. The table below shows the amount of radioactive uranium f(t) left after tim

aniked [119]

Answer:

$f(t) = 100(0.25)^t$

Step-by-step explanation:

The general exponential function is,

$f(t)=ab^t$

The points given in the table are,

$(0,100),(0.5,50),(1,25)$

Putting $(0,100),(1,25)$ in the general equation, we get

$\Rightarrow 100=ab^0$

$\Rightarrow a=100$

And

$\Rightarrow 25=ab^{1}$

$\Rightarrow ab=25$

Putting the value of a,

$\Rightarrow 100b=25$

$\Rightarrow b=0.25$

Now the exponential function becomes,

$f(t) = 100(0.25)^t$
