well done

well, a function for a relationship means, the x-coordinates must not repeat in a set, namely that for every "y" there must be a unique "x" coordinate, no X-REPEATS.

so for example in a relation that say is { (3, 4) , (5, 4) , (7, 4) , (10, 11) }, we do have y-coordinates repeated, but for a function that doesn't matter, our x-coordinates are not repeated thus, it's a function.

in this case, let's see the relationship set, just a few points { (3,5) , (3,6) , (3,8) , (6,10)}, well darn, we have 3 repeated three times in the x-coordinate slots, therefore is not a function, just a relation.

On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours. Find both the miles driven per hour and the hours driven per mil

amid [387]

Miles driven per hour is 60 miles per hour

Hours driven per mile is 0.01667 hours per mile

<em><u>Solution:</u></em>

Given that,

On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours

Therefore,

Miles driven = 210 miles

$Time\ taken = 3\frac{1}{2}\ hour = \frac{7}{2} = 3.5\ hour$

To find: miles driven per hour and the hours driven per mile

<h3><u>Miles driven per hour</u></h3>

$\frac{miles}{hour} = \frac{210}{3.5}\\\\\frac{miles}{hour} = 60\ miles\ per\ hour$

<h3><u>Hours driven per mile</u></h3>

$\frac{hours}{miles} = \frac{3.5}{210}\\\\\frac{hours}{miles} = 0.01667\ hours\ per\ miles$

Thus both the miles driven per hour and the hours driven per mile are found

A can in the shape of a cylinder has a diameter of 8 inches and a height of 10 inches. Which measurement is closest to the total

Alex

Answer:

Step-by-step explanation:

To find the total surface area of the cylinder

We get

S.A=2πr^2+2πrh

S.A=2×3.142×4×4+2×3.142×4×10

S. A=100.544inches sq+251.36inches sq

S. A=351.904inches sq

When you divide powers, you subtract them.

12-3=9

B. 5^9 is the answer.

I hope this helps!
