The formula for slope is y2-y1/x2-x1. This would be (-12--3)/(-4-8)=3/4. The slope is 3/4. Hope this helped!
Answer:
Step-by-step explanation:
We get to use the simple version of the half life equation:
where N is the amount of radioactive element left after a specific number of years,
N0 is the initial amount of the element,
t is the number of years (our unknown), and
H is the Half life of the element. For us,
N is 61
N0 is 70,
t is unknown,
H is 24 years. Filling in:
. We begin by dividing both sides by 70 to get:
and then take the natural log of both sides:
which allows us to bring down the exponent to the front on the right side:
. We divide both sides by ln(.5) to get:
and then multiply both sides by 24 to get:
t = 4.8 years
Answer:
![\frac{1}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D)
Step-by-step explanation:
If Minni raked 1/3 of what Karen raked, then you multiply
1/3 x 1/3 or (Karen's amount) x (Minni's amount)
The correct answer would be 1/9 because to multiply fractions, you multiply:
The numerators (1 x 1)
and
The denominators (3 x 3)

ANSWER
The circumcenter is (2,1)
EXPLANATION
The midpoint of BC is (-3,2)
The equation of the perpendicular bisector of BC is x=2
The midpoint of AB is (-1,1)
The midpoint of AB is (-1,1)
The perpendicular bisector of AB is y=1.
These two lines intersect at (2,1).
The point of intersection of the perpendicular bisectors of a triangle is called the circumcenter of the triangle.
400 times 679
is 271,600.First we multiply 400 ×9 (=3,600),
Second we multiply 400*70(=28,000),then we multiply 400× 600(=240,000),
and last we add them together (3,600 + 28,000+240,000=271,600).
