A13 foot ladder is leaning against a wall. if the point where the ladder meets the wall is 12 feet above the ground, how far from the base of the wall is the ladder

The distance of  the base of the wall to the ladder is 5 Feet .

Step-by-step explanation:

As given

A 13 foot ladder is leaning against a wall.

If the point where the ladder meets the wall is 12 feet above the ground.

As shown in the figure given below.

Now by using the pythagorean theorem

Hypotenuse² = Perpendicular² + Base²

AB² = AC² + BC²

As

AB = 13 foot

AC = 12 foot

Put in the above

13² = 12² + BC²

169 = 144 + BC²

BC² = 169 - 144

BC = 5 Feet

Therefore the distance of  the base of the wall to the ladder is 5 Feet .

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
