Answer: 3. -x, y

Step-by-step explanation: we know that

A point reflected across the y-axis has this rule

(a,b)------> (-a,b) so if the center of the original circle was located at (x, y) then the center of the new circle after the transformation will be (-x,y)

Answer:

Option C. (-x,y)

Step-by-step explanation:

we know that

A point reflected across the y-axis has the following rule

(a,b)------> (-a,b)

If the center of the original circle was located at (x, y)

then

the center of the new circle after the transformation will be (-x,y)

A buoy starts at a height of 0 in relation to sea level and then goes up. its maximum displacement in either direction is 6 feet

Vanyuwa [196]

The equation of the model h will be h = 6 × sin(2πt/8). Then the correct option is C.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

A buoy starts at a height of 0 in relation to sea level and then goes up.

Its maximum displacement in either direction is 6 feet, and the time it takes to go from its highest point to its lowest point is 4 seconds.

Then we have

$h=A \times \sin \omega t, \ \ at=0, \ \ h =0$

The maximum displacement of the buoy in either direction is 6 ft, then we have

$h=6 \times \sin \omega t$

The time it takes the buoy to get from the lowest to the highest point is 4 seconds then the oscillation time period will be 8 seconds.

Then we have

$\omega T = 2\pi\\\\\omega = \dfrac{2\pi}{8}$

Then the h will be given as

$h =6\times \sin (\dfrac{2\pi}{8}t)$

More about the function link is given below.

What is the perfect cubes between 1000 and 3000 that are even numbers

Bogdan [553]

<span>12^3 = 1728 and 14^3 = 2744 First, let's reduce the range of numbers to check. The cube root of 1000 is 10 and the cube root of 3000 is 14.4225. So we need to look at the numbers 11, 12, 13, and 14. Not looking at 10 since the question states "BETWEEN 1000 and 3000". Now the only way you're going to get an odd number when multiplying 2 numbers is if both numbers are odd. And since we're looking for perfect cubes, that would imply that we're cubing an even number. So the answers will be 12^3 = 1728 and 14^3 = 2744</span>
