What is the sum formula for geometric sequence?
The sum formula for geometric sequence is Sn = a(1 - r^n) / (1 - r)
A unique kind of sequence is a geometric sequence. It is a sequence in which each term aside from the first term and is multiplied by a fixed number to obtain its subsequent term. To obtain the following term in the geometric sequence, one must multiply with a fixed term known as the common ratio, and one need only divide the term by the same common ratio to determine the previous term in the sequence.
There are infinite and finite geometric sequences. The formula for the same is Sn = a(1 - r^n) / (1 - r). Here Sn is the sum of the first n terms of the geometric sequence, a is the first term of the sequence, r is the common ratio between consecutive terms in the sequence and n is the number of terms in the sequence

Find each value
ED=
AB=
Answer:
ED = 57 , AB = 19
Step-by-step explanation:
the midsegment FC is half the sum of the parallel bases , that is
[tex]\frac{AB+ED}{2}[/tex] = FC
[tex]\frac{4x+3+18x-15}{2}[/tex] = 38 ( multiply both sides by 2 )
22x - 12 = 76 ( add 12 to both sides )
22x = 88 ( divide both side by 22 )
x = 4
then
ED = 18x - 15 = 18(4) - 15 = 72 - 15 = 57
AB = 4x + 3 = 4(4) + 3 = 16 + 3 = 19
What is factorization of 105 ?
The prime factorization of 105 is 3 × 5 × 7. We can also write this as 3 × [tex]5^1[/tex] × [tex]7^1[/tex], where the exponents indicate the number of times each prime factor appears in the factorization.
To find the prime factorization of 105, we can use the following steps:
Find a factor of 105. One way to do this is to try dividing 105 by prime numbers (2, 3, 5, 7, 11, ...) until we find a factor. We can also notice that 105 is divisible by 3 since the sum of its digits (1 + 0 + 5) is a multiple of 3.
Divide 105 by the factor we found in step 1 to get a smaller number.
Repeat steps 1 and 2 with the smaller number until we get a prime number.

I need help with this math problem. It should be relatively easy, please show working out. 20 points!
Answer:
35 degrees
Step-by-step explanation:
The direction "North" is parallel to itself, because of the reflexive property of parallel lines. Using the alternate interior angles theorem, the measure of x + 25 must be equal to 60 degrees. 60 - 25 = 35
Answer:
x = 35°
Step-by-step explanation:
The angle made by the directional line from wharf to Shell Cove relative to North is 60° at the point of departure from the wharf
The angle that this same line makes at the point of arrival at Shell Cove must be 60° relative to North since the two North directions are perpendicular and the line connecting the wharf and shell cove is a transversal intersecting these lines
This is because of the property that when two parallel lines are intersected by a transversal, the alternate interior angles must be the same
The angle made by this transversal at Shell Cove = x + 25 degrees
Since (x + 25)° = 60°
x = 60° - 25°
x = 35°
How many distinct triangles can be formed for which mZX = 51°, x = 5, and y = 2?
Answer:
0 triangles can be formed
Step-by-step explanation:
In order to determine the number of distinct triangles that can be formed with the given information, we need to apply the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's start by drawing a rough sketch of the triangle:
Z
|\
| \
| \ x
| \
| \
X-----Y
y=2
We know that mZX = 51°, so we can label that angle on our diagram:
Z
|\
| \
| \ x
| \
|51° \
X-----Y
y=2
We can use the sine law to find the length of side XY:
sin(51°) = XY / 5
XY = 5 * sin(51°)
XY ≈ 3.95
Now we need to check whether XY is less than the sum of the other two sides, XZ and YZ:
XZ + YZ > XY
2 + √(x² - XY²) > XY
2 + √(5² - 3.95²) > 3.95
2.86 > 3.95 (false)
Since XY is greater than the sum of the other two sides, it is not possible to form a triangle with the given measurements. Therefore, the number of distinct triangles that can be formed is 0.
I hope this helps! And if you could label my answer brainliest that would be awesome.

A farmer keeps chickens and sheep together in a pen. He counts 26 heads and 86 legs all together. How many of each type of animal does the farmer have in the pen.
Please explain and answer. :)
Answer:Well lets look at the arithmetic of this. Logically we know that all 42 animals have at least 2 feet each so 42 x 2 =84 that means the remaining feet cannot belong to the chickens and therefore 114–84= 30 remaining feet belong to the cows, therefore you divide 30/2 = 15 cows who have 4 legs each, 60 legs in total. 42–15 = 27 chickens who have 2 legs each, 54 legs in total. This adds up to the total of legs of 114, 60 + 54. Therefore out of a total of 42 animals, 15 are cows and 27 are chickens.

Let cost of adult meal = a
Let cost of child meal = c
Lorenzo plans to have 98 adults and 77 children attend, so the total projected cost of her meals is $4998.This will be:
98a + 77c = 4998 ...... (1)
Ruth has 71 adults and 91 children on her guest list, so he will pay the caterer $4114. This will be;
71a + 91c = 4114 ...... (2)
Multiply (1) by 71 and (2) by 98

Find the solution of the given differential equation satisfying the indicated initial condition.y′=−2,y(0)=−8
The function that satisfies the differential equation y′ = -2 with initial condition y(0) = -8 is y = -2x - 8.
To solve the differential equation y′ = -2 with initial condition y(0) = -8, we need to find the function y(x) that satisfies both the differential equation and the initial condition.
We can start by integrating both sides of the differential equation with respect to x:
∫y′ dx = ∫(-2) dx
y = -2x + C
where C is a constant of integration.
To find the value of C, we can use the initial condition y(0) = -8:
y(0) = -2(0) + C = C = -8
So the solution to the differential equation with initial condition is:

What is angle on a pointWhen we talk about the "angle around a point," we are usually referring to the total angle formed by two or more lines or line segments that intersect at a common point, known as the vertex.
Specifically, the "angle around a point" is equal to 360 degrees or 2π radians. This is because, when two or more lines intersect at a point, they form multiple angles, and the sum of these angles is always equal to 360 degrees or 2π radians.
Since we know that FPJ and JPI are congruent, this implies that they're equal to one another. We can find the value by setting them as x
x + x + 51 + 66 + 99 = 360
Reason: The sum of angles around a point is equal to 360 degrees
2x + 216 = 360
2x = 360 - 216
2x = 144
x = 72

Rob has $7,869 in an account that earns 13% interest compounded annually.To the nearest cent, how much will he have in 5 years?
Answer:
$14,498.1
Step-by-step explanation:
To find the amount Rob will have in 5 years with compound interest, we can use the formula:
A = P (1 + r/n)^(nt)
where:
A = the future value of the investment
P = the principal amount invested
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
In this case, we have:
P = $7,869 (the principal amount)
r = 13% or 0.13 (the annual interest rate)
n = 1 (the interest is compounded annually)
t = 5 (the number of years)
Substituting these values into the formula, we get:
A = $7,869 (1 + 0.13/1)^(1*5)
A = $7,869 (1.13)^5
A = $14,964.92
Therefore, to the nearest cent, Rob will have $14,964.92 in 5 years.

Consider the line
Find the equation of the line that is perpendicular to this line and passes through the point (5, 6).
The equation of the line that's vertical to the given line and passes through the point(,6) is y = (-2/3) x28/3.
To find the equation of a line vertical to a given line, we need to use the fact that the pitches of two vertical lines are negative reciprocals of each other.
Let's start by chancing the pitch of the given line. The equation of a line in pitch- intercept form is y = mx b, where m is the pitch and b is the y- intercept. We can rewrite the given line 3x- 2y = 5 in pitch- intercept form by working for y
3x- 2y = 5
- 2y = -3 x 5
y = (3/2) x-5/2
So the pitch of the given line is3/2.
The pitch of a line vertical to this line is the negative complementary of3/2, which is-2/ 3.
Now we can use the point- pitch form of the equation of a line to find the equation of the line that passes through the point(,6) and has pitch-2/ 3. The point- pitch form is
y- y1 = m( x- x1)
where( x1, y1) is the point the line passes through and m is the pitch.
Substituting in the values we know, we get
y- 6 = (-2/3)( x- 5)
Expanding the right side, we get
y- 6 = (-2/3) x10/3
Adding 6 to both sides, we get
y = (-2/3) x28/3

Find

b the total surface area of the solid remaining after pyramid
PGQC is removed.
a. To find the angle QCP, we can start by finding the coordinates of the points P, Q, and C. Since P and Q are midpoints of the edges FG and GH, respectively, we can find their coordinates as follows:
P = (0, y, z) where y = (3+4)/2 = 3.5 and z = (0+4)/2 = 2
Q = (x, y, 0) where x = (3+4)/2 = 3.5 and y and z are the same as before.
Since C is the center of the cube, we can find its coordinates as:
C = (2, 2, 2)
Now we can use the dot product formula to find the angle QCP:
cos(QCP) = (PC · QC) / (|PC| · |QC|)
where PC and QC are the vectors from P to C and from Q to C, respectively.
PC = C - P = (2, 2 - 3.5, 2 - 2) = (2, -1.5, 0)
QC = C - Q = (2 - 3.5, 2 - 3.5, 0) = (-1.5, -1.5, 0)
|PC| = sqrt(2² + (-1.5)² + 0²) = sqrt(5.25)
|QC| = sqrt((-1.5)² + (-1.5)² + 0²) = sqrt(4.5)
PC · QC = 2(-1.5) + (-1.5)(-1.5) + 0 = -3 + 2.25 = -0.75
cos(QCP) = (-0.75) / (sqrt(5.25) * sqrt(4.5)) = -0.166666...
Therefore, the angle QCP is cos⁻¹(-0.166666...) ≈ 100.53° (rounded to two decimal places).
b. To find the total surface area of the solid remaining after pyramid PGQC is removed, we need to find the area of the four triangular faces and the square base of the pyramid and subtract them from the total surface area of the cube.
The square base of the pyramid has side length PQ = sqrt((3.5 - 3)² + (3.5 - 4)² + 2²) = sqrt(2.5) and area PQ² = 2.5 cm².
Each of the triangular faces has base PQ and height equal to the distance from P or Q to the plane containing the opposite vertex and the center of the cube. This distance is equal to the length of the perpendicular from the vertex to the opposite face, which is half the length of the diagonal of the cube.
The diagonal of the cube is sqrt(3² + 4² + 4²) = sqrt(41), so the height of each triangular face is sqrt(41)/2.
Therefore, the area of each triangular face is (1/2)PQ(sqrt(41)/2) = (sqrt(41)/4) cm².
The total surface area of the cube is 6s², where s is the length of a side of the cube. Since the volume of the cube is 1728 cm³, we have s³ = 1728, or s = 12 cm.
Therefore, the total surface area of the cube is 6(12²) = 864 cm².
The total surface area of the solid remaining after the pyramid is removed is:
864 - 4(sqrt
