I believe it’s -12x but I may be wrong I hope this helped!
So, you take the equation for y given, y=0.28x+5.92. Then you substitute the values for x in, like so:
y=0.28(2)+5.92=6.42
y=0.28(5)+5.92=7.17
y=0.28(8)+5.92=7.92
So There's your table. Next:
7.88=0.28x+5.92
x=7, so the year when admission was approximately $7.88 is year 7.
Next,
10.04=0.28x+5.92
x=<span>14.7142857143, which rounds to year 15.
I hope this helps!</span>
Answer:
total cost for Samantha to get her degree = $5,128.2
Step-by-step explanation:
Number of trimesters per year = 3
Number of years = 4
∴ Total number of trimesters throughout college = 3 × 4 = 12 trimesters
Tuition per trimester = $2.350
Total tuition (12 trimesters) = 2.350 × 12 = $28.2
cost of books per trimester = $425
cost of books throughout college (12 trimesters) = 425 × 12 = $5,100
total cost for Samantha to get her degree = total cost of tuition + total cost of books
total cost for Samantha to get her degree = 28.2 + 5,100
total cost for Samantha to get her degree = $5,128.2
Answer:
Step-by-step explanation:
we are given half-life of PO-210 and the initial mass
we want to figure out the remaining mass <u>after</u><u> </u><u>4</u><u>2</u><u>0</u><u> </u><u>days</u><u> </u>
in order to solve so we can consider the half-life formula given by
where:
- f(t) is the remaining quantity of a substance after time t has elapsed.
- a is the initial quantity of this substance.
- T is the half-life
since it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5
thus substitute:
reduce fraction:
By using calculator we acquire:
hence, the remaining sample after 420 days is 0.625 kg
