Answer:
0.75 in decimal form or 3/4 in fraction form.

Answer:
Remember that the slope is the change in y/the change in x
Step-by-step explanation:
1. The slope ![\frac{-0.5- 0.5}{3 - (-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B-0.5-%200.5%7D%7B3%20-%20%28-3%29%7D)
= ![\frac{-1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B6%7D)
2. Find "b" which is the y-intercept. Pick one of the two point and the slope.
Let use (-3, 0.5) and the slope is -1/6
y = mx + b
0.5 = -1/6 (-3) + b Solve for b
3 = 3 + b Multiply each term by 6
0 = B
3. Write the equation of the line y = mx + b
y = -1/6x + 0
10x10x10x10x10x10=1000000
![{10}^{6}](https://tex.z-dn.net/?f=%20%7B10%7D%5E%7B6%7D%20%20)
means 10x10x10x10x10x10
as it's basically saying 10 is multiplied by itself 6 times which gives you 1000000
Correct question:
Which reaction describes a beta emission? 2659Fe→ 2759Co + −10e, 88226Ra→ 86222Rn + 24He, 94239Pu + 24He→ 96242Cm + 01n, 54118Xe→ 53118I + +10e
Answer:
2659Fe→ 2759Co + 1e
Step-by-step explanation:
General equation for beta decay is given as;
![^A_zX -> \ ^A_{z+1}Y +\ ^0_{-1} \beta](https://tex.z-dn.net/?f=%5EA_zX%20-%3E%20%5C%20%5EA_%7Bz%2B1%7DY%20%2B%5C%20%20%5E0_%7B-1%7D%20%5Cbeta)
where;
A is the atomic mass of the element
z is atomic number of the element
X is the parent atom
Y is the daughter element
β is beta emission
In beta emission, there is loss of one electron and zero proton, the will cause the daughter element to gain on electron in order to balance the reaction.
Based on beta decay equation above, we select the reaction that describes beta emission.
2659Fe→ 2759Co + 1e
Here;
A = 59
z = 26
z + 1 = 27
