Find the 10th term of the geometric sequence 8,-16,32
Answers
Answer:
4096
GP = {8 , 16 , 32 , 64 , 128 , 256 , 512 , 1024 , 2048 , 4096...} Therefore , the 10th term of the sequence is 4096.

The required 10th term of the geometric sequence 8, -16, 32 is -4,096.
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
To find the 10th term of the geometric sequence 8, -16, 32, we first need to determine the common ratio (r) between consecutive terms.
r = (second term) / (first term) = (-16) / 8 = -2
So the common ratio is -2.
The nth term of a geometric sequence is given by the formula:
[tex]a_n = a_1 * r^{(n-1)}[/tex]
where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, r is the common ratio, and n is the term number.
To find the 10th term, we plug in a1 = 8, r = -2, and n = 10:
[tex]a_{10} = 8 * (-2)^{(10-1)}a10 = 8 * (-2)^9a_{10} = 8 * (-512)a_{10} = -4,096[/tex]
Therefore, the 10th term of the geometric sequence 8, -16, 32 is -4,096.

Step-by-step explanation:
To find the slope through 2 points
m = ( y2-y1)/(x2-x1)

The scatterplot shows the time it takes for a new hot plate to boil various amounts of water, and one lab group’s attempt at a line of best fit.
A graph shows water (cups) labeled 1 to 9 on the horizontal axis and time (minutes) on the vertical axis. A line increases from 1 to 8.
What feedback should another lab group give during a peer review of the work?
The line of best fit is reasonable because it does not go through any points.
The line of best fit is reasonable because it goes through the largest cluster of points.
The line of best fit is not reasonable because it does not go through any points.
The line of best fit is not reasonable because it has more points below it than above it.

Emily wants to hang a painting in a gallery, The painting and frame must have an area of 31 square feet. The painting is 5 feet wide by 6 feet lone, Which quadratic equation can be used to determine the thickness of the frame, x? (5 points) 511 42.22x+31 - 0 4x22x - 1.0 OX.11.31 - 0 O x + 11-1-0
Answers
Answer:
4x² + 22x - 1 = 0
Step-by-step explanation:
The painting is in the form of a rectangle with measurement of 5 feet width and 6 feet length. Let us assume that the frame has a thickness of x feet, hence:
Length of painting and frame = 6 + 2x, breadth of painting and frame = 5 + 2x
Therefore:
Area of painting and frame = length of painting and frame * breadth of painting and frame
Given that the area of painting and frame is 31 ft², substituting gives:
31 = (6 + 2x)(5 + 2x)
31 = 30 + 12x + 10x + 4x²
31 = 30 + 22x + 4x²
4x² + 22x + 30 = 31
4x² + 22x - 1 = 0

Your friend made a mistake when multiplying the coefficients of each term and when adding the exponents of each term.
Correct answer: [tex]\left(12a\right)^{7/10}[/tex]

Substituting given values, we get:
[tex]4a^{(\frac{1}{2})}\cdot 3a^{(\frac{1}{5})}=12a^{(\frac{1}{2}+\frac{1}{5})}=12a^{(\frac{5}{10}+\frac{2}{10})}=\boxed{12a^{(\frac{7}{10})}}[/tex]
