The distance between any two points is the so-called distance formula which is an extension of the Pythagorean Theorem:

d^2=(x2-x1)^2+(y2-y1)^2, where (x1,y1) and (x2,x1) are two points.

In this case:

d^2=(3--6)^2+(5--6)^2

d^2=9^2+11^2

d^2=81+121

d^2=202

d=√202 units

d≈14.21 units (to the nearest hundredth of a unit)

The distance formula is sqrt((x1-x2)^2 + (y1-y2)^2), therefore (3-(-6))^2 = 9^2 and (5 -(-6))^2 = 11^2 so 121 + 81 = sqrt(202), this converted to decimal is ~14.21, so D.

Don works in home construction. He determined that the function t(A)=144a/9.25^2 gives the total number of 9 in. tiles needed to

natima [27]

Answer:

$t(400)=673$ .

Don required 673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.

Step-by-step explanation:

Given:

The given function is:

$t(A)=\frac{144}{9.25^2}A$

Here, $A$ represent the area to be covered, $t$ represent the number of tiles required to cover the given area.

So, if $A=400$ , it means that the area to be covered is 400 square units.

Now, if we find $t(400)$ , it means we need to find the number of 9 inch tiles to cover area of 400 units.

So, we plug in 400 for $A$ to evaluate $t(400)$ .

$t(400)=\frac{144}{9.25^2}\times 400=\frac{144\times 400}{85.5625}=\frac{57600}{85.5625}=673.19\approx673$

Therefore, it means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
