Answer:

If angle dgf as an angle of 108

that means that the equation would look like this x + 4x-2=108

= 5x-2=108

then you solve for x

5x=110

110/5 = 22 = x

hope that answers your question

A sample of radium has a weight of 1.5 mg and decays

Oliga [24]

Answer: $(b)$

Step-by-step explanation:

Given

Initial mass of radium is $A_o=1.5\ mg$

It decays by half every 6 years i.e. $T_{\frac{1}{2}}=6$

For radioactive decay, sample at any time is given by

$\Rightarrow A=A_o2^{-\dfrac{t}{T_{\frac{1}{2}}}}$

Insert the values

$\Rightarrow A=1.5\cdot 2^{\dfrac{-t}{6}}\\\\\Rightarrow A=1.5\cdot \left(\dfrac{1}{2}\right)^{\dfrac{-t}{6}}\\\\\Rightarrow A=1.5\cdot (0.5)^{\dfrac{t}{6}}$

Thus, option (b) is correct.

What is the length help me

kirza4 [7]

Since AM = 2cm and AC = 6cm we can write the following:

AM + AC = 8cm

So, now we only create a fraction demonstration the length from AM to AC:

$\frac{2}{8}$ which can be simplified to $\frac{1}{4}$

Conclusion/answer:

The length from AM to AC is: $\frac{1}{4}$

Hope it helped,

In this in this equation y equals 14 x what is the constant of proportionality

lions [1.4K]

Answer:

We conclude that the value of the constant of proportionality.

k = 14

Step-by-step explanation:

We know that if 'y' varies directly with 'x', we use the equation

y ∝ x

y = kx

where 'k' is called the constant of proportionality.

Given the equation

y = 14x

comparing with the equation

y = kx

Thus,

k = 14

Therefore, we conclude that the value of the constant of proportionality.

k = 14
