which is the explicit formula for the sequence above?
Answer:
aₙ=5*4ⁿ⁻¹
Step-by-step explanation:
The common ratio is r=80/20=20/5=4
The explicit formula for a geometric sequence is aₙ=a₁*rⁿ⁻¹ where aₙ is the nth term, r is the common ratio, and a₁ is the first term.
Given:
a₁=5
r=4
Therefore, the explicit formula for the sequence is aₙ=5*4ⁿ⁻¹

What is the coefficient of x4 y3 term in the expansion of ( x-2y )7?
The coefficient of x⁴y³ term in the expansion of (x - 2y)⁷ is 280.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.
Given expression:
(x - 2y)⁷
Expand this as given below,
(x - 2y)³ × [(x - 2y)²]²
(x³ + 6x²y + 12xy² + 8y³) × [(x² + 4y² - 4xy)]²
Solve the above expression to get,
x⁷ + 14x⁶ + 84x⁵y² + 280x⁴y³ + 560x³y⁴ + 672x²y⁵ + 448xy⁶ + 128y⁷
Here, the coefficient of the x⁴y³ is 280,
Therefore, the coefficient of x⁴y³ term in the expansion of (x - 2y)⁷ is 280.

is it true or false?? i will mark brainlest the correct answer
Answer:
True
Step-by-step explanation:
In order to calculate this, we simply need to replace the variable c with the value of -8 and solve the inequality.
-9c >= 63
-9 * -8 >= 63
72 >= 63
Since both values are negative the product will be positive. This product is 72 which is in fact greater than 63, thus making the statement True

Quadrilateral ABCD is a parallelogram if both pairs of opposite sides are congruent show that quadrilateral ABCD is a parallelogram by finding the length of the opposite side pairs
Answer:
D. 21, 14
Step-by-step explanation:
As the question said, a parallelogram is formed when both pairs of opposite sides are congruent. That means that 21 and 3y are equal, as are y + 7 and 2y.
21 = 3y
/3 /3
7 = y
y + 7 = 2y
-2y -2y
-y + 7 = 0
- 7 - 7
-y = -7
* -1 * -1
y = 7
In both instances, y = 7. Now let's substitute that.
21 = 3(7)
21 = 21 is true.
7 + 7 = 2(7)
14 = 14 is true.
With that, the lengths of the opposites sides are 21 & 14, which is D.

9514 1404 393
Answer:
20.25 mm
Step-by-step explanation:
Arc length is given by the relation ...
s = rθ
where r is the radius and θ is the central angle in radians.
There are π radians in 180°, so the arc length is ...
s = (5 mm)(232°×π/180°) = 20.25 mm
The arc length is about 20.25 mm.

A show pony weighs at least 900 pounds. After a recent weigh in, the owner of a show pony amended the diet of his pony, increasing the animal's caloric intake, with the hope that the pony would gain weight to be shown in a few months. The data shown in the table and scatter plot below represents the pony's additional daily caloric intake and recorded weight gain (in pounds) of the show pony over the last ten weeks.
Additional Daily Calories Consumed Weight Gained
(in pounds)
1,500 3
1,575 7
1,650 3
1,725 4

Part A: Use the data shown in the table and scatter plot to create an approximate equation for the line of best fit.
Part B: In complete sentences, describe the show pony's weight gain in terms of the units used in the data.
Part C: According to the equation for the best fit line for the data, approximately how much weight would you expect the pony to gain in a week if its additional daily caloric intake for that week is 2,300 calories?

Answer:
r = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
PR² = PQ² + QR² , substitute values
(r + 4)² = r² + 8²
r² + 8r + 16 = r² + 64 ( subtract r² from both sides )
8r + 16 = 64 ( subtract 16 from both sides )
8r = 48 ( divide both sides by 8 )
r = 6
