Answer:

y(x)=10.5/sqrt(x)

Step-by-step explanation:

Since y is inversely proportional to the square root of x, it can be written as y=a/sqrt(x). To compute a, we will use the point given in the question (2.25,7). 7=a/sqrt(2.25), a=10.5. The function is y(x)=10.5/sqrt(x)

Answer:

y = 1/(x**2) + 6.8025

Step-by-step explanation:

This says that y = 1/(x**2) + b where b is the y intercept.

So using the point given

y = 1/(x**2) + b

7 = 1/(2.25**2) + b

7 = 1/5.0625 + b

7 = 0.1975 + b

b = 6.8025

The length of a swimming pool is 22 ft. The width is 40 ft. If the volume of the pool is 2,500 m3, what equation shows you how y
Alexeev081 [22]

Answer:

volume= length x width x height

Step-by-step explanation:

In this instance the height will represent the depth of the pool.

To actually solve it it would look like

2500=(22)(40)(h)

2500=880(h)

2.84=h (or depth)

Urgent help needed!
zalisa [80]

To write this in standard form, you need to eliminate the fraction in the coefficient of variable x. You can do this by multiplying 8 to the two sides of the equation:

8(y) = 8[(-5/8)x + 3]

8y = -5x + 24

Transpose the variable x to the other side:

5x + 8y = 24
