Respuesta:
T₁₀ = 1/16
S₁₀ = 63,9375
Explicación paso a paso:
Dado el término de un médico de cabecera como 32, 16, 8, 4 ...
El enésimo término de un médico de cabecera se expresa como;
Tn = arⁿ⁻¹
a es el primer término
r es la razón común
n es el número de términos
Dado
a = 32
r = 16/32 = 8/16 = 4/8 = 1/2
n = 10 (ya que necesitamos el décimo término de la secuencia)
Sustituir en la fórmula;
Tn = arⁿ⁻¹
T₁₀ = 32 (1/2) ¹⁰⁻¹
T₁₀ = 32 (1/2) ⁹
T₁₀ = 32 (1/512)
T₁₀ = 32/512
T₁₀ = 1/16
Por lo tanto, el décimo término de la secuencia es 1/16.
La suma de un GP se expresa como se muestra;
Sₙ = a (1-rⁿ) / 1-r para r <1
S₁₀ = 32 (1- (1/2) ¹⁰) / 1-1 / 2
S₁₀ = 32 (1-1 / 1024) / 1/2
S₁₀ = 64 (1 - 1/1024)
S₁₀ = 64 (1023/1024)
S₁₀ = 63,9375
por lo tanto, la suma de los primeros diez términos es 63,9375

Ratio tables what’s the missing ratio
Answer:
16
Step-by-step explanation:
To solve we must first find what the given ratios equal
8/5 = 1.6
40/25 = 1.6
48/30 = 1.6
this means that x/10 = 1.6
To find x... multiply both sides of this equation my 10 to get x alone
x=1.6×10
x=16

Cookies cost $3.50 per package. How many packages of cookies can Gail buy if she has \$42 .00? Write an equation and solve.
Answer:
Solve: 12 packagesEquation: n = $42.00¢Step-by-step explanation:
Given
1 package = $3.50¢
∴, ? package = 42.00¢
Equation
Identify the variable. Let n be the variables, then, the equation is: n=$42.00¢
Solve
Since 1 is 3.50
To find 42.00
Divide 42.00 by 3.50
42.00 ÷ 3.50 = 12
Therefore, Gail can buy 12 packages with $42.00¢

2x=8(x^2)
What is the solution of this maths equation?
Answer:
x=0,x=1/4
Step-by-step explanation:
2x=8(x^2)
Subtract 8(x^2) from both sides
2x-8x^2=8x^2-8x^2
Simplify
2x-8x^2=0
Factor 2x-8x^2;
2x-8x^2
=-8xx+2x
Rewrite 8 as 2*4
=-2*4xx+2x
Factor out common term -2x
=-2x(4x-1)
-2x(4x-1)=0
x=0 or 4x-1=0
Solve 4x-1=0;x=1/4
4x-1=0
Add 1 to both sides
4x-1+1=0+1
Simplify
4x=1
Divide both sides by 4
4x/4=1/4
Simplify
x=1/4
The solutions to the quadratic equation are;
x=0,x=1/4

Step-by-step explanation:
A 256- gallon barrel of radioactive Urikium is spilled at a factory. The entire area is evacuated. Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is to toxic for any clean-up efforts, so residents will just have to wait for the Urikium to evaporate. Fortunately, Urikium has a half-life of only three hours. That means that half of the Urikium will evaporate every three hours
Answer:
21 hours
Step-by-step explanation:
Since 2^8 = 256, that means it will take 7 half-lives to become two gallons
7 half-lives * 3 hours = 21 hours
256, 128, 64, 32, 16, 8, 4, 2
Answer:
Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is too toxic for any clean-up efforts. She residents will
Step-by-step explanation:
To solve half-life problems, you use the equations:
f(t) = T0 (1/2)^(t/t1/2). where T0 is the initial mass and T1/2 is the half-life.
So we get f(20)= 5 = T0•(1/2) ^ 20/11
T0 = 17.63 mg
For the second part of the question, we plug 0.5 mg into the equation:
0.5 = 17.63 • (1/2)^ t/11
t = 56.5 days

Explain how you know that x^2-8x+20 is always positive.
Please help.
Answer:
if you rearrange to complete the square, you get (x^2-4)^2 +4
and seeing as anything squared will always be positive or zero, the lowest possible value for (x^2-4)^2 is 0, when x = 4
and 0 + 4 = 4, which is greater than 0, so positive
Step-by-step explanation:
We have x^2-8x+20 is always positive.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
x^2-8x+20
=x^2-2.x.4+16+4
if you rearrange to complete the square,
you get (x^2-4)^2 +4
and seeing as anything squared will always be positive or zero,
the lowest possible value for (x^2-4)^2 is 0, when x = 4
and 0 + 4 = 4, which is greater than 0,
so, positive.

3. Suppose the radius of the larger circle is r. What is its diameter?
d2 =
R2
Answer:
2r
Step-by-step explanation:
You suppose that the radius of a larger circle = r
so diameter = r*2 = 2r
aint really sure tho
Answer:
2R
Step-by-step explanation:
The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.
