Answer:
Find the slope by first creating two points in the form (years, salary)
(0, 66640) ; (8, 73400)
calculate the slope using the correct slope formula
m = (73400 - 66640)/(8 - 0) = 6760/8 = 845
Answer:
1 and 3
Step-by-step explanation:
So they asked you to use the quadratic formula. The quadratic formula is x=-b+/-sqrt b^2-4ac/2a.
So your equation is x^2-4x+3.
x^2 is a. -4 is b. and 3 is c.
x=4+/-sqrt (-4)^2-4(1)(3)/2(1).
This will equal 4+/-sqrt16-12/2
It will simplify to 4+/-2/2.
No you have two equations 4+2/2 and 4-2/2.
4+2/2=3.
4-2/2=1.
Your answers are 1 and 3.
Answer:
-12
Step-by-step explanation:
integer rule = when a + and - comes it is indicated as - so ..
8-20 = -12
we put a minus sighnbecause 20 is the bigger number
Answer:
5x3=15
Step-by-step explanation:
The half-life is 29 years.
116 : 29 = 4
So we will have 4 periods of half-life:
( 1/2 )^4 = 1/16
150 g * 1/16 = 9.375 g
Answer:
9.375 g of strontium -90 will remain after 116 years.
