Answer:
2/5
Step-by-step explanation:
The common ratio is r = (1/10)/(1/5) = 5/10 = 1/2. The first term is a1 = 1/5.
The sum of an infinite geometric series is given by ...
S = a1/(1 -r)
S = (1/5)/(1 -1/2) = (2/10)/(5/10) = 2/5
The sum of the series is 2/5.
_____
It might stick in your head that the sum of 1 + 1/2 + 1/4 + 1/8 + 1/16 + ... is 2. The given series is 1/5 times that.
Answer:
the answer is 2/5

find the slope on the line that passes through the two given one points (-3,4) and (-3.-8)
Answer:
Undefined slope
Step-by-step explanation:
Points: (-3,4) and (-3,- 8)
Slope:
m=(y2-y1)/(x2-x1)
m=(-8-4)/(-3+3)
m=(-12)/0
Since 0 is the denominator, the slope is undefined.
Find f(-2) for the following problems.
Problem A: f(x) = x3 + 5
Problem B: f(x) = x2 - 2
Which statement is correct?
a
Problem A > Problem B
b
Problem A < Problem B
Problem A = Problem B
d
Cannot be determined
Answer:
a. Problem A > Problem B
Step-by-step explanation:
Problem A:
f(x) = x3 + 5
f(-2) = (-2)3 + 5
f(-2) = (-6) + 5
f(-2) = -1
Problem B:
f(x) = x2 - 2
f(-2) = (-2)2 - 2
f(-2) = (-4) - 2
f(-2) = -6

Answer:
1A: -282 < 203
1B: -282 < 157
Step-by-step explanation:
The examples below is gonna be comparing x and y, two variables that have some random definition that I don't wanna talk about. :D
This is talking about inequalities, which mean greater than, greater than or equal to, less than, less than or equal to, which is about comparing two or more sets of data.
Death Valley has the least elevation as can be seen by comparing the -282, the 203, and the -157.
We can easily set up the inequalities, as Death Valley has the least, so
Death Valley < Tallahassee, Westmorland
That sign between the three locations mean that Death Valley has less value than the other two.
Tallahassee has the highest elevation, as the other two locations, Death Valley and Westmorland are both in the negatives.
We know that -157 is greater than -282, as it is closer to 0.
Therefor, Death Valley is the least, and Tallahassee is the highest.
NOTE: THE VALUES ARE TALKING ABOUT SEA LEVEL. THE ELEVATION OF THE LOCATIONS RELATIVE TO THE SEA (WHICH IS 0)

No: of wooden blocks she wants to fit= 70
she'd not be able to fit all the wooden blocks into the box
Step-by-step explanation:
Answer:
No, cannotStep-by-step explanation:
Side of the small block is 2 cm
The volume of a small block is:
V = 2³ = 8 cm³The cubic box with side 8 has volume:
V = 8³ = 512 cm³The blocks can fit inside:
512/8 = 64Since 64 < 70, Indra cannot fit all the blocks

Answer:
1.47 years
Step-by-step explanation:
Given that,
The height of male elephant is given by the formula,
[tex]h=62.5\sqrt[3]{t} +75.8[/tex]
If h = 275 cm, we need to find the age of the elephant.
Put h = 275 cm in the above formula,
[tex]275=62.5\sqrt[3]{t} +75.8\\\\275-75.8=62.5\sqrt[3]{t}\\\\199.2=62.5\sqrt[3]{t}\\\\t=1.47\ years[/tex]
So, the required time be 1.47 years.

The equation r = 4sin(θ) represents a circle. What is the radius of the circle, and what is the symmetry of the graph? The radius is 2 units, and the graph is symmetric about the line Theta = StartFraction pi Over 2 EndFraction. The radius is 4 units, and the graph is symmetric about the line Theta = StartFraction pi Over 2 EndFraction. The radius is 2 units, and the graph is symmetric about the polar axis. The radius is 4 units, and the graph is symmetric about the polar axis.
Answer:
1) 270 degrees
2) pi/4 rad
Step-by-step explanation:
1.) For which value of theta is sine theta = negative 1?
Given
sintheta = -1
theta = arcsin(-1)
theta = -90degrees
Since sin is negative in the third and 4th quadrant
In the third quadrant, theta = 180 + 90 = 270degrees
In the fourth quadrant, theta = 360 - 90 = 270 degrees
Hence the required value of theta is 270degrees
2) Given the radius of the circle to be 1, the y axis value will also be 1 units
Opposite = 1
adjacent = 1
hyp = √1²+1²
hyp = √2
sin theta = opp/hyp
sin theta = 1/√2
theta = arccsin(1/√2)
theta = 45 degrees
Express in radians
45 degrees = pi/4 radians
Hence the required angle in the first quadrant is pi/4 rad

Pretty please HELP MEEEE A circular flower bed is 19 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi.
SA is the area of flowerbed
radius is 9.5 m (diameter, 19, divided by 2)π(r)²3.14(9.5)²3.14(90.25)SA = 283.385 m²LA is the large area of both flowerbed and sidewalk together
Adding 9.5 and 3 together, the total radius is 12.5 mπ(r)²3.14(12.5)²3.14(156.25)LA = 490.625 m²Subtract SA from LA in order to find teh area of sidewalk.
A = 283.385 - 490.625 = 207.24 m²
ANSWER: 207.24 m² is the area of the sidewalkWhy does everyone keep commenting links on my posts? Please stop, if you don’t know the answer then don’t comment :(

If p(t)=5t4+17t3–8t2+13t–12, use synthetic division to find p( – 4).
Answer:
the value of this function p(t) at t = -4 is also 0
Step-by-step explanation:
Recall that synthetic division in a problem such as this one returns a remainder, which is sometimes zero and is sometimes not. If not, then the remainder is the value of the given polynomial when evaluated at a given argument. We are to determine the remainder here when t = -4:
Setting up synthetic division:
-4 / 5 17 -8 13 -12
-20 12 -16 12
------------------------------------
5 -3 4 -3 0
Since the remainder is 0, the value of this function p(t) at t = -4 is also 0.

- Una persona depositó una cierta cantidad de
dinero en un banco que paga el 6.2% de inte
rés simple anual. Si al cabo de 10 años los
intereses ganados alcanzan los RD$ 19 840,
¿de cuánto fue el depósito realizado?
• ¿A qué porcentaje de interés fueron deposi-
tados RD$ 48 000.00 para que transcurridos
15 meses los intereses devengados sean de
RD$ 3 450.00?
¿En qué tiempo un capital de RD$ 72 475.00
depositado a una tasa de interés simple anual
de un 4% produce intereses de RD$ 36 237.50?
Step-by-step explanation:
Este ejercicio se puede hacer de dos formas, o bien pasas los días a años o calculas el interés simple diario.
Para pasar 89 días a años simplemente tenemos que dividir 89 entre 365 días, lo que nos da 0,243835616 años. Una vez tengamos todos los datos expresados en el mismo tiempo, podemos calcular el interés.
Interés simple ejercicio resuelto
Para pasar el interés simple de anual a diario hacemos lo mismo dividimos 4% entre 365 días. Dándonos el mismo resultado.

Answer:
a) ∠EAB = 180° - 90° - 30° = 60°
∠EBA = 180° - 90° - 60° = 30°
a) ∠EBA = 30°
b) ∠DCA = 180° - 90° - 30° = 60°
∠EBA ≅ ∠DAC, ∠EAB ≅ ∠DCA, ∠AEB ≅ ∠CDA
ΔEBA ≅ ΔDAC because of the AAA postulate
c) EB ≅ DA, EA ≅ DC, AB ≅ CA
d) AB = CA given
sin ∠EAB = EB/AB (sin 60°) EB = (0.8660)AB
cos ∠EAB = EA/AB (cos 60°) EA = (0.5)AB
cos ∠DAC = AD/CA (cos 30°) AD = (0.8660)CA
sin ∠DAC = CD/CA (sin 30°) CD = (0.5)CA
ED = EA + AD
ED = (0.5)AB + (0.8660)CA
since AB = CA, ED = 1.366CA
since EB = (0.8660)AB and AB = CA, then EB = 0.866CA
since CD = 0.5CA,
EB + CD = 0.866CA + 0.5CA = 1.366CA
EB + CD = 1.366CA
1.366CA = 1.366CA
Proof: ED = EB + CD
Ms Matthews has 200 sheets of construction paper she will give each of her 27 students an equal number of whole sheets to use for a project how many sheets will each students an equal number of whole sheets will each students get ? how sheets many will be left over?
Answer:
Each student will get 7 sheets with 11 sheets left over.
Step-by-step explanation:
divide 200 and 27 to get 7
7 sheets for each student
then multiply 27 and 7 to see how many sheets of paper she gave to her students.
that will give you 189
then 200-189=11 sheets left over
