If 14 g of a radioactive substance are present initially and 2 yr later only 7 g remain, how much of the substance will be present after 5
yr?
Answer:
2.47g
Step-by-step explanation:
Given that Ao=14
A(t)= Aoe^kt
k =2yrs
Considering the function where Ao is the initial substance, k is the rate of decay and t is the time.
At the 2nd year A(t) is 7
That is,
7 = 14e^2k
Solve for k
7/14 = e^2k
In(7/14) = 2k
k = In(7/14)÷2
k = In(0.5)/2
k = -0.34657
Hence, A(t)= 14e^-0.34657
So, when t is 5
A(5) = 14e^-0.34657×5
= 2.4749
Approx = 2.47g
common denominator for 1/4 and 7/10
Step-by-step explanation:
Common Denominator is 20.
Some multiples of 4 are 4, 8, 12, 16, 20.
Some multiples of 10 are 10, 20, 30, 40, 50.
This shows that 20 is a common denominator because 20 is a multiple of both 4 and 10.

Have a good day!
please help ASAP!!!!
Answer:
B.
Step-by-step explanation:
Plug in the x-values for x in the answer choices. The result will be the y-value of the table.
For example,
A. 3(-1)^2+3(-1)-2 = -2
That is not the y-value for -1, so A is not the answer.
B. 3(-1)^2-3(-1)-2=4.
4 works here, but make sure to try all the numbers.
3(0)^2-3(0)-2 = -2
3(3)^2-3(3)-2 = 16
B is the answer because with each x-value you substitute in for x, you get its corresponding y-value.
(-1,4) (0,-2) (3,16)

The measure of Zo is 150°. What is the value of mZb+mZc+mze?
O 90°
ОООО
120°
210°
Answer:
∠b + ∠c + ∠e = 120°
Step-by-step explanation:
From the attached figure,
∠b + ∠e + ∠a = 180° (Linear pair)
Given that, ∠a = 90°
∠b + ∠e = 90° ...(1)
Also,
∠c + ∠d = 180° (Linear pair)
Given that,
∠d = 150°
∠c = 180°-150°
= 30°
Adding ∠c to both sides of the equation (1).
∠b + ∠e + ∠c= 90° + ∠c
∠b + ∠c + ∠e = 90° + 30°
= 120°
Hence, the meaure of ∠b + ∠c + ∠e is equal to 120°

Determine if the point (12, 20) is on the
graph of y = 2x – 5. Justify your answer.
Answer:
456[67]98
Step-by-step explanation:
Answer:
Step-by-step explanation:
for the point (12,20) to be on the graph the equation of the line has to be true.
y=2x-5 so is it true that
20= 2*12-5
20=19 false
so the point is not on the graph

b) What is the probability of getting all 3 tails? (My Answer is 1/8)
c) What is the probability of getting all 1 head and 2 tails? (My Answer is 3/8)
d) What is the probability of getting all 2 heads and 1 tail? (My Answer is 3/8)
My Question:
e) What do the probabilities from parts (a) to (e) add up to?
Answer:
1/8 + 1/8 + 3/8 + 3/8 = 2/8 + 6/8 = 8/8 = 1
So the answer would be 1.
If the terminal point determined by t is (-5,-4), then
\sin (t) =
;
\cos (t) =
;
\tan (t) =
.
Answer:
The trigonometric ratios associated with (-5, -4) are [tex]\sin t \approx -0.625[/tex], [tex]\cos t \approx -0.781[/tex] and [tex]\tan t = 0.8[/tex].
Step-by-step explanation:
Let [tex]\vec u = (x,y)[/tex]. From Trigonometry, we remember the following definitions for the trigonometric ratios, dimensionless:
[tex]\sin t = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex] (1)
[tex]\cos t = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex] (2)
[tex]\tan t = \frac{y}{x}[/tex] (3)
If we know that [tex]x = -5[/tex] and [tex]y = -4[/tex], then the trigonometric ratios are, respectively:
[tex]\sin t = \frac{-4}{\sqrt{(-5)^{2}+(-4)^{2}}}[/tex]
[tex]\sin t \approx -0.625[/tex]
[tex]\cos t = \frac{-5}{\sqrt{(-5)^{2}+(-4)^{2}}}[/tex]
[tex]\cos t \approx -0.781[/tex]
[tex]\tan t = \frac{-4}{-5}[/tex]
[tex]\tan t = 0.8[/tex]
The trigonometric ratios associated with (-5, -4) are [tex]\sin t \approx -0.625[/tex], [tex]\cos t \approx -0.781[/tex] and [tex]\tan t = 0.8[/tex].

get the ball into the hole. The winner is the player with the lowest score. After playing 18 holes, Jillian's mean is 2.4 and
Dawn's mean is 3.3. Which explains who won the game?
O Jillian won the game because her score varied less than Dawn's score.
O Jillian won the game because the person with the lower mean took fewer putts on average for each hole.
O Dawn won the game because the person with the greater mean played better.
O Dawn won the game because her mean absolute deviation was less than Jillian's.
