Answer:
Problem and solution
Step-by-step explanation:
"Struggle", "threat", and "trouble" are words that describe a problem.
"Hope", "possibility", and "future" are words that describe a solution.
Step-by-step explanation:
Say you have these 2 fractions
Cross multiply as following;
If in the end, both numerator and denominator are equal, then the fractions are equivalent.
Examples:
Example 1
Cross multiply
They're equivalent.
Example 2
Cross multiply
They're not equivalent.
Answer:
<em>4√5</em>
Step-by-step explanation:
The length of the radius of the circle will be the distance between the two coordinates. Using the formula:
D = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinates (-4‚-2) and (-8‚-10)
R = √(-8-(-4))²+(-10-(-2))²
R = √(-4)²+(-8)²
R = √16+64
R = √80
R = √16*5
R = 4√5
<em>Hence the length of the radius of this circle is 4√5</em>
Answer:
Whether or not a given isotope is radioactive is a characteristic of that particular isotope. Some isotopes are stable indefinitely, while others are radioactive and decay through a characteristic form of emission. As time passes, less and less of the radioactive isotope will be present, and the level of radioactivity decreases. An interesting and useful aspect of radioactive decay is half-life, which is the amount of time it takes for one-half of a radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by coTnditions and is independent of the initial amount of that isotope.
