Answer:
g(5) = - 3
Step-by-step explanation:
you substitute the 5 from the g(5) into your x from your equation so
- x + 2 =
- ( 5 ) + 2 =
- 5 + 2 =
-3
Answer:
Area of geometric figures mentioned calculated.
Step-by-step explanation:
Square Perimeter = 4 x sides of square = 20. So, each equal side of square = 20 / 4 = 5
Area of square = ( Side )^2 = ( 5 )^2 = 25
Area of triangle = 1/2 (Base) (Height) = 1/2 x 3 x 3.5 = 5.25
Answer:94%
Step-by-step explanation:
Half life of a radioactive element is the time taken for half it's mass to disintegrate away.it means after attaining half life,what will be left is 100-50=50%.
Let the 100% mass of C-14,be x
Then 5730years=1/2 of X
Then 660 years=y of X
Where Y is the fraction of C-14 that has disintegrate as at 1988.
5730/660=1/2X/yX
5730/660=1/2/y
Cross multiplying
5730×y=660×1/2
5730y=330
Y=330/5730=0.05759
In %,5.76%
Amount of C-14 left is
100-5.76=94.24=94% as at 1988.
180 degrees i think tell me if im wrong
