Remember the cost cannot be a number lesser than zero. so the domain must be such that the total cost C(m) is not negative. Also the range will always be 0.5 and above provided our domain is greater than or equal to zero.
Una persona observa un pájaro que esta en la copa de un árbol de 2 m de altura y un gato que esta en el pie del mismo árbol a la
espera de atrapar el pájaro. y si la persona esta a 3 m del árbol.

b) ¿de que dependerá que los ángulos de elevación y de deprecio cambien en este estilo d análisis?
c)¿es posible que alguno de los ángulos(el de elevación o el de deprecio) sean mayores o iguales a 99º? explica tu respuesta

1 answer:
Answer:
a) About 40° and 5 °; b) the height of the person; c) none
Step-by-step explanation:
(a) Angles of depression and elevation
The angle of depression is about 40°.
The angle of elevation is about 5°.
(b) Dependence of angles
The angles of elevation and depression depend on the height of the person.
The taller the person, the smaller the angle of elevation and the larger the angle of depression.
(c) Limitations of angles
There is no chance that either angle could be greater than or equal to 99°.
Each is part of a right triangle.
If one angle is a right angle, each of the other two angles must be less than 90°.

To solve this, we are going to use the compound interest formula: 
where
is the final amount after 
years
is the initial investment
is the interest rate in decimal form
is the number of times the interest is compounded per year
For the first 4 years we know that:
, 
, 
, and since the problem is not specifying how often the interest is communed, we are going to assume it is compounded annually; therefore, 
. Lest replace those values in our formula:
Now, for the next 6 years the intial investment will be the final amount from our previous step, so
. We also know that: 
, 
, and . Lets replace those values in our formula one more time:
We can conclude that Collin will have <span>£3691.41 in his account after 10 years.</span>
