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.
Answer:
Distance is equal to 10.
Step-by-step explanation:
Use the distance formula: d=√((x_2-x_1)²+(y_2-y_1)²)
d = √(9-3)^2 + (1-9)^2
d = √(6)^2 + (-8)^2
d = √36 + 64
d = √100
d = √10

Answer:
trinomial
Step-by-step explanation:
Since this polynomial has 3 different terms, this is, in fact, a trinomial.

The equation of a circle that contains the point (–2, 8) and has a center at (4, 0) is (x - 4)² + y² = 10²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The circle contains the point (–2, 8) and has a center at (4, 0), hence:
The equation is:
(x - 4)² + (y - 0)² = 10²
(x - 4)² + y² = 10²
The equation of a circle that contains the point (–2, 8) and has a center at (4, 0) is (x - 4)² + y² = 10²
