Answer:

2x+9y=18

Step-by-step explanation:

Distribute the denominator

y=-2/9x+2

Answer:

  84 feet

Step-by-step explanation:

This problem involves several steps. The first step is to realize that the given figure does not show the required number of vertical stringers. It shows 5, but there will be 7 of them. The given diagram is helpful in that it shows a vertical stringer on the centerline of the arches.

The second step is to write a function that will tell you how long the stringer will be. I find it convenient to write the equation for an arch shape such as this using the parent function h(x) = 1-x^2. This parent function gives an arch of height 1 and width 1 from center (a total width of 2). You want an arch that is 16 ft high and 40 ft wide (one side from center), so you must scale this parent function both horizontally (by 40) and vertically (by 16). It becomes ...

  H(x) = 16(1 -(x/40)^2)

The taller arch is twice this height, so the length of a vertical stringer at position x is

  vertical length = 2H(x) -H(x) = H(x)

That is, the function H(x) we defined can be used to find the length of the stringers.

The third step is to find the stringer lengths. It can save some energy if you realize that the problem is symmetrical, so that the stringer at x=-30 is the same length as the one at x=30. We need to find stringer lengths every 10 feet from -40 feet to +40 feet. Of course, the ones at ±40 feet are zero length, because that is where the two arches meet.

  H(-30) = 16(1 -(3/4)^2) = 7

  H(-20) = 16(1 -(1/2)^2) = 12

  H(-10) = 16(1 -(1/4)^2) = 15

  H(0) = 16

Then the fourth step is to add up the stringer lengths, rounding the result as required.

  7 +12 +15 +16 +15 +12 +7 = 16 + 2(34) = 84 . . . . feet (no rounding needed)

Finally, you need to answer the question asked:

  The sum of vertical stringer lengths is 84 feet.

HOW MUCH LONGER IS A 6 3/16-IN. METAL PIPE THAN A 4 5/8-IN. PVC PIPE
Aloiza [94]

Answer:

1  9/16 in (or 25/16in)

Step-by-step explanation:

4 5/8 = 4 10/16

6 3/16- 4 10/16 =  1 9/16

Material of pipes is irrelevant

THIS IS THE FOURTH TIME I HAVE POSTED THIS QUESTION. I HAVE BEEN STUCK ON THIS SAME QUESTION FOR AN HOUR

So the culture banner size has length x, width x (since it is square)
The sports banner has length x+12, width x.

The area of the sports banner is length x width = x(x+12) = x²+12x.

Now, lets look at the tiles.

- The monomial, x, a factor of the expression is the width of the sports banner.

- The binomial (x+12) is the length of the spots banner (this is given!)

- The second degree term of the expression x²+12 is x², the area of the culture banner

- The first degree term of the expression x²+12x is 12x, it represents the increase in area, since the area went from x² to x²+12x
