Find the slope of the line passing through the points (5, 7) and (5, -9)

Fantom [35]

Answer:

undefined

Step-by-step explanation:

To find the slope, we can use the slope formula

m = (y2-y1)/(x2-x1)

= (-9-7)/(5-5)

= (-16)/0

When we divide by zero, the slope is undefined

HELPPPP MEEEEEEEE ! Can you have a right triangle where the lengths of the legs are whole numbers and the length of the hypotenu

MArishka [77]

No, u cant

a^2 + b^2 = c^2.....pythagorean theorem used on only right triangles...where a and b are the legs and c is the hypotenuse

a^2 + b^2 = 23^2
a^2 + b^2 = 529...so u would have to find 2 square numbers that add up to 529. There aren't any.

A rectangular soccer field is 6w yards wide

lutik1710 [3]

Answer:

$\sqrt{(6w)^2+(10w)^2}$

Step-by-step explanation:

You need to use Pythagoras' theorem:

$c=\sqrt{a^2+b^2}$ where a and b are the sides of the field.

So the distance from one corner to the opposite corner = $\sqrt{(6w)^2+(10w)^2}$

Starting with 195 grams of a radioactive isotope, how much will be left after 3 half-lives?

MrMuchimi

After one half-life: $\frac{1}{2}\times 195=97.5$ grams.

After two half-lives: $\frac{1}{2} \times 97.5=48.75$ grams.

After three half-lives: $\frac{1}{2} \times 48.75=24.375$ grams.
