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.

using the variable in write a variable expression for the word phrase. 5 times a number plus 13.
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

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

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.

Find the surface of this triangular prism please
Answer:
270cm²
Step-by-step explanation:
The formula is given as
S = bh × l (s1 + s2 + h)
l = 7cm
h = 5cm
s1 = 12 cm
s2 = 13cm
b = 12 cm
Surface Area = 12 cm × 5 cm × 7 cm(12 cm+ 13 cm+ 5cm)
= 60cm² × 7 cm(30 cm)
= 60cm² + 210 cm²
= 270 cm²

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.

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

PLZ ANSWER THIS I CANT FIGURE OUT THE SECOND ONE
(INSTANTANEOUS ROC)
I will give you brainiest if you answer it right
Answer:
Step-by-step explanation:
The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.
Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.
