Answer:
The number before a variable. For example, 4x. 4 would be the coefficient, and x would be the variable.
The percent increase of the second year was 85.71%
Step-by-step explanation:
The exponential growth formula is y=a(1+r)^x
where;
y=population after x years
a=original population
r=growth rate as a decimal
x=number of time interval that have passed
Let starting population be p
The first year increase in the population was 40% this means;
r=0.4 , x=1 and a=p thus the equation will be
y=p(1+0.4)^1 ⇒⇒y=1.4 p
In the second year the population of birds of an island became 7 times more than before which is 7p
7p= 7*1.4p= 9.8p
Increase will be;
9.8p-1.4p=8.4
% increase will be;
8.4/9.8 *100 =85.71%

Answer:
70
Step-by-step explanation:
55 + 55 = 110
180 - 110 = 70
The angle is congruent to 70º
(-4)-4 could be some integers to subtract and get -8
