Find the slope of the line that passes through (4,2) and (4,5)

Hunter-Best [27]

Answer: Undefined

Step-by-step explanation:

(slope = m)

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{4-4}=\frac{3}{0}$

(3 divided by 0 is undefined, so the slope is undefined)

A Demolition ball weigths 2 tons . what is the weigtht in ounces?also what is a demolition ball?

kkurt [141]

Answer:

64,000 oz

Step-by-step explanation:

A demolition (wrecking) ball is a relatively large dense mass, often spherical, typically swung from a crane, used to demolish buildings or other structures.

We assume you want to convert from a US short ton (2000 pounds) to Avoirdupois ounces (16 ounces per pound).

Then your ball's weight is ...

(2 tons)(2000 lb/ton)(16 oz/lb) = 64,000 oz

What is the image of (x, y) after a translation of 3 units right and 7 units down?

fenix001 [56]

Translation involves changing the position of a shape.

The image of point (x,y) after a translation of 3 units right and 7 units down is: $\mathbf{(x - 3,y - 7)}$

The point is given as: (x,y)

The rule of translation 3 units right is:

$\mathbf{(x,y) \to (x-3,y)}$

The rule of translating 7 units down is:

$\mathbf{(x,y) \to (x,y - 7)}$

So, we have:

$\mathbf{(x - 3,y) \to (x - 3,y - 7)}$

Hence, the image of point (x,y) after a translation of 3 units right and 7 units down is: $\mathbf{(x - 3,y - 7)}$
