A geometric series that results in a sum of -69,905 include the following: B. ∑ -1/5(4)^k.
How to calculate the sum of a geometric series?Also, the sum of a geometric series is given by this mathematical expression:
[tex]S=\frac{a_1(1-r^n)}{1-r}[/tex] or [tex]\sum^{n-1}_{k=0}a_1(q)^k[/tex]
Where:
aₙ or n represents the nth term of a geometric sequence.q or r represents the common ratio.a₁ represents the first term of a geometric sequence.When the common ratio r = 4, n = 10, and the first term (a₁) = -1/5, we have the following:
[tex]\sum^{10-1}_{k=10} \frac{-1}{5} (4)^{10} = -69,905[/tex]
In conclusion, a geometric series whose sum would result in a sum of -69,905 is given by the second expression.

What is the measure of all exterior angles of a pentagon
Answers
Answer:
72 degrees for each exterior angle and 360 degrees for all of them summed.
Step-by-step explanation:
An exterior angle of a polygon is the angle between the line extending one of its sides and the next side. As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees. All these angles are equal, so each one is 360/n.
For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.

A snail travels at a rate of 2.37 feet per minute.
a. Write a rule to describe the function.
b. How far will the snail travel in 6 minutes
A. d(t) = t/2.37; 2.53ft
B. d(t) = t + 2.37; 8.37 ft
C. d(t) = 2.37t; 14.22 ft
D. d(t) = 6t; 14.22 ft
Answers
Answer:
C. d(t) = 2.37t; 14.22 ft
Step-by-step explanation:
2.37 per minute is multiplication so A and B are definitely wrong
Another way to check is 2.37*6=14.22 so the answer is C
Answer:
D. d(t) = 6t; 14.22 ft
Step-by-step explanation:
d(t)= 2.37t; 14.22 ft
d(t)= 2.37t; 14.22 ft
Answer:
a. f(t)=2.37t
b. 14.22 feet
Step-by-step explanation:
We are given that:
A snail travels at a rate of 2.37 feet per minute.
a. write a rule to describe a function.
Let t describe the time and f(t) be a function how far snail travels
then, f(t)=2.37×t
where the unit of t is in minutes and that of f(t) is feet
b. how far will the snail travel in 6 minutes
we have to find f(t) at t=6
f(6)= 2.37×6
= 14.22 feet
Hence, snail traveled 14.22 feet in 6 minutes
2.37/minute
14.22 feet in six minutes
Answer:
Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.
Step-by-step explanation:
Speed of Snail = 2.37 feet per minute
To write the rule we use relation of Speed, Distance and time
Distance = Speed × Time
So, Distance cover by snail in t minutes is given by f(t) = 2.37 × t
⇒ f(t) = 2.37t
Distance traveled by Snail in 6 minutes , f(6) = 2.37 × 6 = 14.22 feet
Therefore, Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.

A population of bacteria is treated with an antibiotic. It is estimated that 5,000 live bacteria existed in the sample in
before treatment. After each day of treatment, 40% of the sample remains alive. Which best describes the graph of
the function that represents the number of live bacteria after x days of treatment?
Answers
Answer:
The answer is A. f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0, because 2,000 of the bacteria remain alive.
Step-by-step explanation:
Answer:
The correct option is A.
Step by step explanation:
The exponential function is defined as
Where, a is initial value and b is growth factor or decay factor.
The initial population of bacteria is 5000.
After each day of treatment, 40% of the sample remains alive. It means the growth factor or decay factor is
Therefore the required function is
The horizontal asymptote is y=0 because
Therefore option A is correct.

Answers
Answer:
a) $654
b) 27 unidades cuadradas
c) 721
Step-by-step explanation:
a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?
Una docena = 12
Por eso:
12 bolígrafos = $ 7848
1 bolígrafo = $ x
Cruz multiplicar
12 bolígrafos × $ x = 1 bolígrafo × $ 7848
$ x = 1 bolígrafo × $ 7848/12
$ x = $654
b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?
Área de un triángulo =
= 1/2 × Base × Altura
1/2 × 9 × 6
