The explicit formula for a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-5}{-1}[/tex] = 5 , then
[tex]a_{n}[/tex] = - [tex]5^{n-1}[/tex]
13
Using the explicit formula for a geometric sequence
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 48 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{96}{-48}[/tex] = - 2 , then
a₁₀ = - 48 × [tex](-2)^{9}[/tex] = - 48 × - 512 = 24576

Find the 43rd term of the sequence
-3.0, -2.5, -2.0, -1.5
Answer:
18.5
Step-by-step explanation:
First determine the common difference. Here, it is 0.5.
Multiply that by the term number, which is 43 here.
43 x .5 = 21.5
Then add the principal, negative 3.
21.5 - 3
18.5
What’s the volume of the cake if the radius is 8 inches
and the height is 5 inches?
Answer:
1005 in^3
Step-by-step explanation:
Think of this cake as a cylindrical solid of base radius 8 in and height 5 in.
The volume is V = (base area)(height), which here is:
V = (pi)*(8 in)^2*(5 in) = 320pi in^3, or approximately 1005 in^3
in the opposite figure the unit of length is the centimeter
(the points O K and P are collinear )
(the points O B and A are collinear)
(KB) and (PA) are parallel
OK=X,OP=Y
KB=5
KP=6
and PA=8
CALCULATE THE LENGTH OP
Answer:
see in the picture, we have: y = 6 + x
=> x = y - 6
because KB//PA, using Thales Theorem, we have:
[tex] \frac{ok}{op} = \frac{kb}{pa} \\ \\ = > \frac{x}{y} = \frac{5}{8} \\ \\ < = > \frac{y - 6}{y} = \frac{5}{8} \\ \\ < = > 5y = 8(y - 6) \\ \\ < = > 5y = 8y - 48\\ \\ < = > 3y = 48 \\ \\ = > y = 16[/tex]
because OP = y => OP = 16

Cuales son las diferencias entre bisección , triseccion y bisectriz ? , por favor lo necesito urgente
Answer:
Primero, la bisección consiste en dividir una figura en dos partes iguales, esto se puede aplicar a cualquier figura, desde un segmento hasta un cuadrado o algo más complejo.
Por ejemplo, en el caso del segmento, una bisección sería una línea que corta el segmento justo por el punto medio.
Por otro lado, una trisección es similar, solo que en este caso dividimos una figura en 3 partes iguales.
Finalmente tenemos la bisectriz, esta es una semirrecta con origen en el vértice de un ángulo, de tal forma que divide al ángulo en dos partes iguales.
La bisectriz se diferencia con la bisección pues la bisectriz solo se aplica a ángulo, mientras que la bisección se aplica a cualquier figura.
Además, la bisectriz en sí misma es una figura geométrica, pues es una semirrecta, mientras que la bisección sería un operador que actúa sobre una figura, y aunque puede ser representada con una semirrecta o una recta, no es necesariamente una.
Ambas se diferencian de la trisección pues la bisectriz y la bisección dividen en dos, mientras que la trisección divide en tres.
Alexander has a bag that contains pineapple chews, cherry chews, and watermelon chews. He performs an experiment. Alexander randomly removes a chew from the bag, records the result, and returns the chew to the bag. Alexander performs the experiment 40 times. The results are shown below: A pineapple chew was selected 8 times. A cherry chew was selected 11 times. A watermelon chew was selected 21 times. Based on these results, express the probability that the next chew Alexander removes from the bag will be cherry chew as a percent to the nearest whole number.

Bryan calculated the area of a square to be 18/32 square foot. Which shows the side length of the square? (Hint: Simplify. Also, area of a square is side x side.)
Answer:
x = 0.75 feet
Step-by-step explanation:
The area of a square is 18/32 square foot
We need to find the side length of the square.
The area of a square of side x is given by :
[tex]A=x^2[/tex]
Substitute all the values,
[tex]x=\sqrt{A} \\\\x=\sqrt{\dfrac{18}{32}} \\\\x=0.75\ feet[/tex]
So, the side length of the square is equal to 0.75 feet.

The endpoints of the directed line segment AB are A(−3, 4) and B(5, 10). Find the coordinates of point P along AB¯¯¯¯¯¯¯¯ so that the ratio of AP to PB is 1 to 3.
Answer:
The coordinates of P is (-1,5.5)
Step-by-step explanation:
Here, we want to find the coordinates of the point that divides the segment into the ratio 1 to 3
To do this, we are going to use the section formula
We have this as;
(x,y) = (nx1 + mx2)/m+ n, (ny1 + my2)/m + n
where m = 1 , n = 3
(x1,y1) = (-3,4)
(x2,y2) = (5,10)
Substituting these values, we have;
(x,y) = (3(-3) + 1(5)/4 , (3(4) + 1(10)/4
(x,y) = (-9+ 5)/4 , (12 + 10)/4
(x,y) = (-1, 5.5)
y = -x - 2 | what is the slope and y-intercept?
slope is -1
y-int is -2
its in y=mx+b form
b is the int
m is the slope
Remember from now on ,
The coefficient of x in slope-intercept form ( y = ax + b ) of the linear equations, is the slope of the line.
Thus : y = -1 ×( x ) - 2
The coefficient of x in the above function is - 1 so the slope of the above function is - 1 .
_________________________________
To find the y-intercept of any equations we have to put 0 instead of x in the equation and solve the equation to find the value of y which is the y-intercept of our equation.
y = - x - 2
put 0 instead of x
y = - 0 - 2
y = - 2
Thus the y-intercept is - 2 .

can some answer this math question
Answer:
A
Step-by-step explanation:
To multiply powers of a variable, add the exponents:
[tex]x^m\cdot x^n = x^{m+n}[/tex]
This rule works for all exponents, positive, negative, or zero. Also, remember that [tex]x^0=1[/tex].
Also, remember the definition of negative exponent: [tex]x^{-n} = \frac{1}{x^n}[/tex]
To multiply the two monomials, start by multiplying the coefficients, 14 and 4. That gives 56, so your answer begins with 56.
Now for the powers of x, [tex](x^3)(x^{-5}) = x^{3+(-5)} =x^{-2} = \frac{1}{x^2}[/tex]
For the powers of y, [tex](y^{-4})(y^4)=y^{4+(-4)} = y^0 = 1[/tex][tex](y^{-4})(y^4) = y^{-4+4} = y^0 =1[/tex]
Your answer is
[tex]56 \cdot \frac{1}{x^2} \cdot 1 =\frac{56}{x^2}[/tex]

PLEASE HELP Adam has a rectangular swimming pool. He fills it with water to a depth of 5 feet. The water has a VOLUME of 1200 cubic feet.
Step-by-step explanation:
Given that,
The depth of the pool is, h = 5 feet
Volume of the pool, V = 1200 cubic feet
We need to find the possible values for the dimensions of the pool. We know that the volume of a rectangle is given by :
[tex]V=lbh[/tex]
Where
l and b are length and breadth
So,
[tex]lb=\dfrac{V}{h}\\\\lb=\dfrac{1200}{5}\\\\lb=240[/tex]
The first possibillity for dimension is (10×24). Another can be (12×20).
Divide. Round to the nearest tenth.

Step-by-step explanation:
Write the slope and y-intercept of this linear equation: 3y + 6 = –2x
Answer:
slope = -2/3
y-intercept = -2
Step-by-step explanation:
3y + 6 = -2x
Conver to slope intercept form
3y = -2x - 6
y = -2/3x - 2
Follow the form y = mx + b, so m is the slope and b is the y-intercept
