The sum of the infinite geometric progression is S = ( 64/7 )
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the sum of the geometric progression be represented as S
Now , the equation will be
S = 16 , -12 , 9 , -( 27/4 ) ...
The sum of the infinite GP is S = a / ( 1 - r ) , where r is the common ratio
Substituting the values in the equation , we get
a₁ = 16
a₂ = -12
So , the common ratio r = a₂ / a₁
The common ratio r = -3/4
Substituting the values in the equation , we get
The sum of the infinite GP is S = a / ( 1 - r )
The sum of the infinite GP is S = 16 / ( 1 - ( -3/4 ) )
The sum of the infinite GP is S = 16 / ( 1 + 3/4 )
The sum of the infinite GP is S = 16 / ( 7/4 )
The sum of the infinite GP is S = ( 16 x 4 ) / 7
The sum of the infinite GP is S = ( 64/7 )
Hence , the sum of GP is ( 64/7 )

Rosa dives into a pool from a diving board that is 3 meters above the surface of the water. During the dive, she descends to a depth of –2.8 meters, relative to the surface of the water. Which value represents the change in Rosa’s elevation, in meters, during the dive, relative to the diving board?
Rosa's change in elevation, relative to the diving board, in meters during the dive, which is a measure of her displacement, is -5.8 meters.
What is a displacement?Displacement is the change in the position of an object, with regards to a frame of reference. Displacement is a vector quantity, that has both magnitude and direction, indicated by the sign (positive or negative), and the magnitude, which is the measured value.
The height of the diving board above the surface of the water = 3 meters
The depth to which Rosa descends relative to the water surface = -2.3 meters
Therefore, Rosa's initial elevation when on the diving board = 3 meters
Rosa elevation when at the depth to which she dives = -2.8 meters
Her change in elevation can be obtained by finding her displacement from the diving board, when she descends to the depth of -2.8 meters.
Rosa's change in elevation, Δh = Final elevation - Initial elevation
Therefore, Δh = -2.8 m - 3 m = -5.8 m
Rosa's change in elevation, during the dive, in meters, relative to the diving board is -5.8 metersLearn more on the displacement here: https://brainly.com/question/18537476

A child's toy is in the shape of a square pyramid. The pyramid stands 20 inches tall and each side of the base measures 24 inches.
Half of the surface area of the pyramid is black and the remainder is yellow.
What is the surface area of the toy that is yellow?
Enter your answer, rounded to the nearest tenth, in the box.
in²
Answer:
The answer is 768.0 square inches.
Step-by-step explanation:
The surface area of a square pyramid can be calculated by adding the area of its four triangular faces to the area of its base, which is a square.
First, we'll find the area of the base:
24 inches x 24 inches = 576 square inches
Next, we'll find the area of each triangular face:
1/2 * 24 inches * 20 inches = 240 square inches
So, the total surface area of the pyramid is:
576 square inches + 4 * 240 square inches = 1,536 square inches
Finally, we'll find the surface area that is yellow:
1,536 square inches / 2 = 768 square inches
Rounding to the nearest tenth, we have:
768 square inches = 768.0 square inches
So, the surface area of the toy that is yellow is 768.0 square inches.

Use point-slop form to write the equation of a one that passes through the point (16, -16) with slip 1/2
Step-by-step explanation:
you made so many typos.
let's see :
the point-slope form of a line is
y - y1 = a(x - x1)
"a" being the slope, (x1, y1) being a point on the line.
in our case
y - -16 = 1/2 × (x - 16)
y + 16 = x/2 - 16/2 = x/2 - 8
y = x/2 - 24
or
y = (1/2)x - 24

You use a coordinate plane to design a poster for the Florida Strawberry Festival. The vertices of the design are A(2,4),B(34,4), C(2,-44) , and D(34,-44) . The coordinates are measured in inches. Find the least number of square yards of paper you need to make the poster.
The least number of square yards of paper required to make the poster is 11 square yards.
How did we get the value?The area of a rectangle can be found by multiplying the length of its sides. To find the length and width of the rectangle, we can subtract the x and y values of the opposite vertices.
The length of the rectangle is 34 - 2 = 32 inches, and the width is -44 - 4 = -48 inches. We will have to make the width positive to find the area, so the area is 32 * 48 = 1536 square inches.
Since 1 square yard is equal to 144 square inches, we need to divide 1536 by 144 to find the number of square yards: 1536 / 144 = 10.67 square yards.
Therefore, the least number of square yards of paper required to make the poster is 11 square yards.

Given: DEF
Prove: DEF is isosceles.
Both the side of triangle DEF have equal distance DF = DE. so it is isosceles triangle.
How can you demonstrate that an isosceles triangle is made up of the specified vertices?
The distance between any two of the supplied points must be the same for two pairs of the given points in order to determine whether the given points are the vertices of an isosceles triangle. We can infer that DF = DE from the DF, FE, and DE data mentioned above.
we have 3 coordinates of triangle .
D(x1,y1) = D(1 , 2)
F(X2,Y2) = F(-2 , -2)
E(X3,Y3) = E(-3 , -1)
if given triangle is isosceles triangle than distance DF = DE.
Distance between two points :-
Distance (DF) =[tex]\sqrt{((x_1 - x_2)^{2} + (y_1 - y_2)^{2})} = \sqrt{((1 + 2)^{2} + (2 +2)^{2})} = 5[/tex].
Distance (DE)= [tex]\sqrt{((x1 - x3)^{2} + (y1 - y3)^{2})}= \sqrt{((1 + 3)^{2} + (2 + 1)^{2})} = 5[/tex]
hence, both the side have equal distance DF = DE. so it is isosceles triangle.

A regular hexagon whose perimeter is 12 can be inscribed in a certain rectangle, as shown. What is the area of this rectangle?
The area of this rectangle is 4 * √11 square units
What is the area of this rectangle?The perimeter of a regular hexagon can be divided equally into the lengths of its six sides.
So, the length of each side of the hexagon is 12 / 6 = 2 units.
Since the hexagon is inscribed in a rectangle, the length of the rectangle is equal to the length of two sides of the hexagon, or 2 * 2 = 4 units.
Let's call the height of the rectangle "h."
Then, the length of one side of the equilateral triangle is 2 units and the height is h, so using the Pythagorean theorem:
h^2 + (2/2)^2 = (2 * √3)^2
h^2 + 1 = 12
h^2 = 11
h = √11
So, the area of the rectangle is equal to its length multiplied by its width:

where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
Given data ,
The terminal side of angle θ intersects the unit circle in the first quadrant at ( 3√10/10,√10/10 )
So , the equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Substituting the values of x and y in the equation , we get
x = 3√10 / 10
x = 3/√10
And , y = √10/10
y = 1/√10
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
So , the value of cos θ = ( 3/√10 ) and sin θ = ( 1/√10 )
On simplifying the equation , we get
cos t = ( 3/√10 )
cost t = 0.94868
Hence , the value of cos t = 0.94868
