Answer:

22.25 feet

Step-by-step explanation:

The height difference between the posts is 9 feet.

Use Pythagorean theorem:

c² = a² + b²

24² = 9² + b²

b = √495

b ≈ 22.25

What is exact the slope of the line through (-9, 6) and ( -3 ,9 )
Tatiana [17]
Slope = (y2 - y1) / (x2 - x1)
(-9,6)....x1 = -9 and y1 = 6
(-3,9)...x2 = -3 and y2 = 9
now we sub and solve
slope = (9 - 6) / (-3 - (-9) = 3 / (-3 + 9) = 3/6 = 1/2 <=

What is the value of x?
Svetllana [295]

Answer:

x = 4

Step-by-step explanation:

ΔTRQ is an isosceles right triangle, so if we find the value of RT then the value of 'x' will be the same

We can find RT by creating a proportion based on the ratio of sides in a 30-60-90° triangle which, respectively, is 1 : \sqrt{3} : 2

2\sqrt{3}/RT = \sqrt{3}/2

cross-multiply:

\sqrt{3}· RT = 4\sqrt{3}

RT = 4

Therefore, x = 4

When testing for current in a cable with eleven ​color-coded wires, the author used a meter to test four wires at a time. How ma
Sav [38]

Answer:

The number of tests required is 330.

Step-by-step explanation:

We have to find the total number of combinations of four wires.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

Four wires from a set of 11.

So

C_{11,4} = \frac{11!}{4!(11-4)!} = 330

The number of tests required is 330.
