Answer:
Step-by-step explanation:
Since this is a test/homework, I'll give you a hint.
A triangle always is 180 degrees. If you add up all the sides, it should be 180.
A horizontal line is 180, if you add up the two sides (or the "line" that is crossing through the horizontal one) it'll be 180.
Just think of it like this: 180 is king. No matter what you add together, if its not 180, its wrong.
Hope this helps!
Answer:
He earned $114 in interest.
The final amount in the account is $874
Step-by-step explanation:
Initial balance (b): $760
Interest rate (i): 0.05
Period (n): 3 months
Simple interest applications yield the same amount in interest every period. Therefore, the total simple interest earned can be defined by:
![I = n*B*i\\I= 3*760*0.05\\I=114](https://tex.z-dn.net/?f=I%20%3D%20n%2AB%2Ai%5C%5CI%3D%203%2A760%2A0.05%5C%5CI%3D114)
The final amount (A) in the account is the initial balance plus the interest earned in 3 months.
![A = 760 +114\\A=874](https://tex.z-dn.net/?f=A%20%3D%20760%20%2B114%5C%5CA%3D874)
He earned $114 in interest and the final amount in the account is $874

Answer:
the number of bacteria increases at a rate of 15% each day
Step-by-step explanation:
Given the function :
f(x) = 256(1.15)^x
The function represents an exponential growth function ; comparing the equation with the general form of an exponential growth function :
f(x) = A(1 + r)^t
A = the initial value of the population, = 256
(1 + r),; r = growth rate
Therefore, to solve for r ;
1 + r = 1.15
r = 1.15 - 1 ; r = 0.15
Hence, growth rate = 0.15 = 0.15 * 100% = 15%
Hence, the number of bacteria increases at a rate of 15% each day
