Answer:

The answer is the 'Area of the pool'

Step-by-step explanation:

The diving board is an elevated board that is used for diving and it is placed where the depth of the water has a minimum of 12 ft deep for a 1 meter diving board, with the width of the pool at least 16 feet and the length at least 32 feet.

The maximum capacity is a a function of the Area of the pool and the area of the pool can be calculated with:

Length x width = Area of a Pool.

The Area of the pool is a lurking variable and it best explains the correlation between maximum capacity and the number of diving boards at the pool.

Write the equation of the line with the given point and slope. (4,4); slope= 7/4
inn [45]

Answer:

4=7/4*4-3

Step-by-step explanation:

Since the equation for a line is <em>y=mx+b </em>(where <em>m </em>is the slope and <em>b </em>is the y-intercept), we can fill in part of the equation with the coordinates. So far we have- <em>4=m4+b. </em>We can then add the slope into the equation, turning it to <em>4=7/4*4+b. </em>To find the y-intercept, you replace <em>x </em>with zero and solve for <em>y. So, </em>lets multiply <em>7/4 </em>and <em>4 </em>and simplify the equation to <em>4=(7*4)/4+b.</em> Next, we'll simplify the right side, turning the equation to <em>4=7+b. </em>Now, all we have to do is subtract <em>7 </em>from the right side of the equation, leaving us with the result of <em>b=-3.</em> We'll add that into our equation now, giving us our answer of 4=7/4*4-3

elena-s [515]

Answer:

x + 26

Step-by-step explanation:

Step 1: Write out expression

2 - (-8x - 6) + 24 - 7x - 6

Step 2: Distribute

2 + 8x + 6 + 24 - 7x - 6

Step 3: Combine like terms (x)

x + 2 + 6 + 24 - 6

Step 4: Combine like terms (constant)

x + 26

The pole casts a 12-foot shadow when the sun is at a 40° angle of elevation. Which equation could Kim use to find x, the length
bonufazy [111]

Answer    

Find out the length of the pole .

To proof

As given

The pole casts a 12-foot shadow when the sun is at a 40° angle of elevation.

x represented the length of pole .

As shown in the diagram

By using the trignometric identity

tan \theta = \frac{Perpendicular}{Base}

tan 40^{\circ} = \frac{x}{12}

tan40° = 0.839099631 ( approx )

Put in the above

x = 12 × 0.839099631

x = 10.1 foot (approx)

Therefore the  length of the pole in  10.1 foot (approx) .
