Answer:
y =
Step-by-step explanation:
Given
x(y + 2) = 3x + y ← distribute parenthesis on left side
xy + 2x = 3x + y ( subtract 2x from both sides )
xy = x + y ( subtract y from both sides )
xy - y = x ← factor out y from each term on the left side )
y(x - 1) = x ← divide both sides by (x - 1)
y =
O B. 4x3 + x2 - 4x -6
O C. 4x3 + x2 - 20x-5
O D. 4x3 + x2 - 5x -5
Answer:
The answer is option c.
4x³ + x² - 20x - 5
Answer:
C
Step-by-step explanation:
Answer:
Simple, 4*pi*r^2
Step-by-step explanation:
The correct answer is 4πr^2
is a difference of squares: (y + 15)^2
is a difference of squares: (y – 15)(y + 15)
is not a difference of squares
is a difference of squares: (y – 15)^2
Answer:
Step-by-step explanation:
There are approximately 7.5 × 10¹⁸ grains of sand on earth.
There are approximately 7 × 10²⁷ atoms in an average human body.
A. There are more atoms in an average human body. When comparing the order of magnitude of each number 27 it greater than 18.
7 × 10²⁷ > 7.5 × 10¹⁸
B. Now we will calculate how many times more atoms are in a human body compared to grains of sand on earth.
=
≈ 1 × 10²⁷⁻¹⁸
≈ 1 × 10⁹
≈ 10⁹
There are approximately 1,000,000,000 atoms more in a human body compared to the grains of sand on earth.
The height of the rocket after 6 seconds is 630 feet
Given the polynomial function that represents the height of the rocket expressed as:
f(t) = -16t^2 + 200t + 6
If the time the rocket take to rise is 6 seconds, hence;
f(6) = -16(6)^2 + 200(6) + 6
f(6) = - 576 + 1200 + 6
f(6) = 630 feet
Hence the height of the rocket after 6 seconds is 630 feet
