I think it is 130. I hope this helps! :D
Answer:
let height of ||g be 'b', then base of ||g be 3b.
area of ||g=base×height
75cm
2
=3b×b
b
2
=25
b=5cm, therefore height =5cm
Answer:
B
Step-by-step explanation:
A is wrong, it increases
C is wrong, the coefficient does not determine if it is linear (straight), the exponent does.
D is wrong, you don't need to know a point to determine if it is linear, (if you have 3 points you can though. )
The <em><u>correct answer</u></em> is:
46.6 days
Explanation:
The general form for exponential growth is
, where A is the total amount, p is the initial amount, r is the percent of growth, and t is the amount of time (in this case, days).
We do not know the initial amount, the total amount, or the amount of time. We do know that r, the percent of growth, is 1.5%; 1.5% = 1.5/100 = 0.015:

We also know we want the total amount, A, to be twice that of the initial amount, p:

Divide both sides by p:

Using logarithms to solve this,

B .35 line the numbers up by the decimals then go from top to bottom starting from each individual column.
