We will select the third row from the pascal triangle to expand the binomial expression (22³ + 3y²)² which is equal to
(22³ + 3y²)² = 22⁶ + 63888y² + 9y⁴
We know that when we need to expand the expression (a + b)² we select the coefficients from the row of triangle beginning with 1,2 which is (1,2,1).
And when we write the expansion we note that with each new term we decrease the power of a and increase the power of b.
Thus the expansion can be written as
(a + b)² = 1a² + 2ab + 1b²
which we normally write as
(a + b)² = a² + 2ab + b² (1)
According to the question we have been the expression as
(22³ + 3y²)² which is equal to the above expression where,
a = 22³ and b = 3y²
Putting the required values in equation (1) we get
(22³ + 3y²)² = (22³)² + 2(22³)(3y²) + (3y²)²
= 22⁶ + 63888y² + 9y⁴
Hence we will select the third row from the pascal triangle to expand the binomial expression (22³ + 3y²)² which is equal to
(22³ + 3y²)² = 22⁶ + 63888y² + 9y⁴

What is a pendulum?
Answer:
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position
EXAMPLES:
the tick in a grandfather clock, a wrecking ball suspended by a chain or link
Step-by-step explanation:
hope this helps! please mark brainliest:)
A pendulum is a simple device consisting of a weight suspended from a fixed point, allowing it to swing back and forth under the force of gravity
Pendulum: A pendulum is a simple device consisting of a weight suspended from a fixed point, allowing it to swing back and forth under the force of gravity. The bob is typically attached to a string, rod, or wire that allows for free movement.
When a pendulum is set in motion, it swings back and forth in a regular and repetitive pattern.
The motion of a pendulum is governed by several factors, including the length of the pendulum, the mass of the bob, and the gravitational acceleration.
The swinging motion of a pendulum is influenced by two fundamental principles:
1. Period: The period of a pendulum is the time it takes for the pendulum to complete one full swing from one side to the other and back. The period depends on the length of the pendulum and is not affected by the mass of the bob. A longer pendulum will have a longer period, while a shorter pendulum will have a shorter period.
2. Oscillation: The pendulum oscillates due to the force of gravity acting on the bob. As the pendulum swings to one side, it gains potential energy, which is then converted into kinetic energy as it swings back. This energy transfer causes the pendulum to continue swinging back and forth.

Andrea and Peter are riding their bicycles in the same direction on the same path. Andrea started 6 miles ahead of Peter and is traveling at a rate of 12 miles per hour. Peter is traveling at a rate of 14 miles per hour. After how many hours will Peter catch up to Andrea? Write and solve an equation to model the problem. Explain the meaning of the solution.
Answer:
3 hours
Step-by-step explanation:
Step one:
given
Andrea started 6 miles ahead of Peter and is traveling at a rate of 12 miles per hour.
let the number of hours be x
and the total distance traveled be y
y=6+12x------------1
the initial distance is 6 miles
the distance traveled after x hours = 12x
Peter is traveling at a rate of 14 miles per hour.
y=14x------------2
the initial distance is 0 miles
the distance traveled after x hours = 14x
Step two:
let us equate the two expressions above
6+12x=14x
14x-12x=6
2x=6
divide both sides by 2
x=6/2
x= 3 hours
it will take 3 hours for both of them to cover the same distance

Tammy made a recipe that called for 3/4 teaspoon of salt. If the recipe is cut in half, how much salt is needed?
Answer:
answer is A your welcome
Answer:
If the recipe is cut in half, 3/8 teaspoon of salt is needed.
Step-by-step explanation:
Since the recipe is cut in half, we need to find 1/2 of 3/4. This means we need to multiply 1/2 times 3/4. For the numerator, 1 times 3 equals 3. For the denominator, 2 times 4 equals 8. The fraction is 3/8.
How many portions of 8 ¾ ounces each can be made from a boneless roast weighing 28 pounds?
Number of portions of 8 ¾ ounces each can be made from a boneless roast weighing 28 pounds is 51 7/35.
Here,
A boneless roast weighing = 28 pounds
Each portion = 8 3/4 ounces
We have to find the number of portion.
What is Division method?
Division method is used to distributing a group of things into equal parts.
Now,
Since, 1 pound = 16 ounces
Hence, 28 pound = 28 x 16 = 448
So, Number of portions = 448 ÷ 8 ¾ = 448 ÷ 35/4 = 51 7/35
Therefore, Number of portions of 8 ¾ ounces each can be made from a boneless roast weighing 28 pounds is 51 7/35.

athletic shoes: $79.99
discount: 40%
Answer:
48$ -specific (not rounded)
Step-by-step explanation:
There could be other solutions that can work. Such as counting the 79.99 to just 80. But for the very SPECIFIC value, you have to find 40% of 79.99 by multiplying it by .4 . 79.99*.4 = 31.99. After that, you would subtract 79.99 and 31.99 which would get you to 48.
Answer:
$47.99
Step-by-step explanation:
79.99*40/100
79.99*0.4
40% of $79.99 = $32.00 ( rounded )
79.99 - 32 = $47.99

Answer:
1) y=1/2x+4 and y=-2x-4
2) y-9 = -2(x+7)
Step-by-step explanation:
1) Perpendicular lines must have reciprocal slopes. So, the sign must be switched and the numerator and denominator must be switched.
2) Point-slope form is [tex]y-y_{1} = m(x-x_{1})[/tex]
So plug the slope and point in.
y - 9 = -2 (x - (-7))
y-9=-2(x+7)
Square number (2x+5y)(3x^2-4xy+2y^2)
Answer: 6x³+7x²y-16xy²+10y³
Step-by-step explanation:
( 2x + 5y )( 3x² - 4xy + 2y²)
⇒ (2x * 3x² ) = 6x³
⇒ (2x * - 4xy) = -8x²y
⇒ (2x * 2y² ) = 4xy²
⇒ (5y * 3x² ) = 15x²y
⇒ (5y * - 4xy) = -20xy²
⇒ (5y * 2y² ) = 10y³
( 2x + 5y )( 3x² - 4xy + 2y²) = 6x³-8x²y+4xy²+15x²y-20xy²+10y³
= 6x³+7x²y-16xy²+10y³

Answer:
exact form 296/3 decimal form 98.6666666 mixed number form 98 2/3
Step-by-step explanation:
Answer:
First result: X = 248/3 or 82.67 Second result: X = 260/3 or 86.57
Step-by-step explanation:
1st one: 7x + 8(x + 1/4) = 3(6x - 90 - 8)
7x + 8x + 2 = 18x - 270 - 24
15x + 2 - 2 = 18x - 246 - 2
15x - 18x = 18x - 18x -248
-3x = 248 --> -3x/3 = 248/3
X = 248/3 or X = 82.67
2nd one: 7x + 8(x+1/4) = 3(6x - 90) - 8
7x + 8x + 2 = 18x - 270 - 8
15x + 2 - 2 = 18x - 262 - 2
15x - 18x = 18x -18x - 260
-3x = 260 --> -3x/3 = 260/3
X = 260/3 or X = 86.67
