When a child is born, her grandfather decides to put $100 in an account that earns interest. He plans to make no other deposits or withdrawals for 18 years. When the child turns 18 years old, the money in the account will be a birthday gift. The grandfather is choosing between two options:
Option 1: An account that grows by 10.5% each year.
Option 2: An account that grows by $20 each year.
Which option will result in a better 18th birthday gift? Explain your reasoning.
Answers
Answer:
option (1) is a better 18th Birthday gift of child by Grandfather.
Step-by-step explanation:
Amount deposited in bank at time of birth by Grandfather is $100.
And there is no other deposits and withdrawals for 18 years.
So,
Principal amount =$100
Time = 18 years
Rate of interest of bank = 10.5%
Option 1:- An account That grows by 10.5% each year
we know that Bank give compound interest on the deposit amount
then Compound interest = C.I=P(1+r) with an exponent of t
C.I= 100(1 + 10.5 over 100)with an exponent of 18
C.I= 100*6.0328
C.I= $603.28
Option 2:- An account that grows by $20 each year
Here,
Amount credited in account for 18 years = $20
So, Total amount after completion of 18 years = 10+18*20
=460

B. Denise’s collection increases by 4 stuffed animals per year.
C. Denise’s collection increases by 3 stuffed animals per year.
D. Denise spends $4 per year on stuffed animals.
Answers
The statement best describes the rate of change is "Denise's collection increases by 4 stuffed animals each year".
What is rate of change ?
The rate of change is the speed at which a variable changes over a specific period of time.
According to the given question
We have
An equation a(n) = 3+4n, which describes the number of stuffed animal in Denise collection, a after n, number of years.
For the rate of change
Differentiate the given equation w.r.t n
⇒[tex]\frac{d(a(n))}{dn} =\frac{d}{dn} (3) + \frac{d}{dn} (4n)[/tex]
⇒[tex]\frac{d}{dn} a(n) = 0+ 4 =4[/tex]
⇒ the number of stuffed collection increases by 4 each year.
Hence, option B is correct.

En una compañía se realiza una encuesta a 200 personas, se encontró la siguiente distribución, en el uso de máquinas eléctricas, mecánicas y computadoras: Eléctricas 110, mecánicas 50, computadoras 60. Mecánicas y computadoras 25, eléctricas y computadoras 35, eléctricas y mecánicas 40. Las tres 20 y 60 nada. A) Encuentre el número de personas que o usan computadora. B) Que usen una maquina eléctrica pero no computadora. C) Que usen solo un equipo. D) Que usen mecánica y eléctrica pero no computadora. E) Cuantos no tienen ni maquina eléctrica ni mecánica.
Answers
Answer:
A) 140
B) 75
C) 80
D) 20
E) 80
Step-by-step explanation:
Para resolver este problema debemos construir un diabrama de Venn y llenarlo según los datos que se nos brindan.
Comenzamos nombrando cada círculo:
E= personas que usan máquinas eléctricas
M= personas que usan máquinas mecánicas
C = personas que usan computadoras.
- Luego llenamos el área central con un 20, el cual representa las personas que usan los 3 tipos de maquinas.
- En la parte exterior del diagrama de Venn colocamos un 60 por las personas que no usan ninguna de las máquinas.
- En la intersección entre M y C restamos:
25-20=5
Entonces colocamos este 5 en esa región.
- En la intersección entre E y C restamos:
35-20=15
Entonces colocamos este 15 en esa región.
- En la intersección entre E y M restamos:
40-20=20
Entonces colocamos este 20 en esa región.
- En la región de E restamos:
110-20-20-15=55
Entonces colocamos este 55 en esa región.
- En la región de M restamos:
50-20-20-5=5
Entonces colocamos este 5 en esa región.
- En la región de C restamos:
60-15-20-5=20
Entonces colocamos este 20 en esa región.
Y obtenemos el diagrama de Venn que representa esta encuesta (Ver figura adjunta)
Y ahora ya lo podemos usar para responder a las preguntas:
A) Número de personas que no usan computadora. Sumamos los números fuera del círculo C:
55+20+5+60=140
B) Número de personas que usan una máquina eléctrica pero no computadora: Sumamos los números dentro del círculo E con excepción de los números compartidos por el círculo C y obtenemos:
55+20=75
C) Número de personas que usan solo un equipo: Sumamos los números no compartidos en los círculos E, M y C
55+20+5=80
D) Número de personas que usan máquina mecánica y eléctrica pero no computadora: Usamos el número compartido entre E y M que no son compartidos con C
20
E) Sumamos el número que se encuentra solo en C y los que están afuera del diagrama:
20´60=80
