Answer:
f(1)=1+
2
1
−3
Step 1: Simplify both sides of the equation.
f(1)=1+
2
1
−3
f=1+2+−3
f=(1+2+−3)(Combine Like Terms)
f=0
f=0
Answer:
f=0

Answer:
The expression that represents the number of days until only 10% remains is T((d) 10 %) =100×.
Step-by-step explanation:
The equation for half life is of the form
A = A₀×.........................................................................(1)
Where
A = Final amount
A₀ = Initial amount
t = Time
h = Half life
For the equation T(d) = 100×2⁽⁻²⁾....................................(2)
We have by comparison with the equation for half life
2 ≡ and and the equation (2) can be written as
Percentage remaining after 2 half lives is
×100=100×
However if the half life of Technetium-99m is 6 hours then we have for one day
×100=100×
Therefore an expression that represents the number of days until only 10% remains is
×100=100× = 10 %
=
= ㏑ = ㏑()
= ×㏑ = ㏑()
= = 3.322
Therefore the expression for the number of days 10 % of Technetium-99m will be remaining is
T((d) 10 %) =100×
Answer:Answer:
y=x*3
Step-by-step explanation
step one: find how many times dose 5 go into 15
15/5=3
then we can do the same thing to see how many 15's can go into 45
45/15=3
therefore, the answer is 3
70 packages can be filled from a jar that contains 7/8pounds of the leaves
<h3>Ratio and proportions</h3>
Fractions are written as a ratio of two integers. If each bad contains 1/80 pound peppermint leaves, then;
1/80pounds = 1 package
To determine the total package for 7/8 pounds of leaves
7/8 pounds = x
Take the ratios
1/80 * 8/7 = 1/x
8/560 = 1/x
x = 560/8
x = 70
70 packages can be filled from a jar that contains 7/8pounds of the leaves
