Answer:
the equation should be corrected to fit the data of the problem. With the corrected equation a mass of 0.5 grams remains after 150 years
Step-by-step explanation:
for the mass y( in grams)
y=23* (1/2)^(t/45), t ≥ 0.
the initial mass is at t=0 , then
y= 23 grams → should be 16 grams
half-life from the equation = 45 years → should be 30 years
the correct equation should be
y=16*(1/2)^(t/30), t ≥ 0
then after 150 years → t= 150
y=16*(1/2)^(150/30)= 16*(1/2)^5 = 16/32 = 0.5 grams
then a mass of 0.5 grams remains after 150 years
Answer:
I'm going to assume that was supposed to be a division sign.. so 26.
Step-by-step explanation:
multiplication/division first
40/5=8
8x2=16
then addition
16+10=26

Step-by-step explanation:
Answer: 3 units right 6 units up
Step-by-step explanation:
coordinate B was first (3,3)
then became (6,9)
X axis is 3 which is left and right
Y axis is also 3 which is up and down
right = positive left= negative up=positive down=negative
the math
you have to add 3 to the right to get positive 6
so the coordinates so far are (6,?)
then you need to add 6 on the y axis for the coordinates to be (6,9)
hope this helped
