To find the slope ...
1) (5,-1)and(2,4)

4+1 / 2-5

5/-3

So slope for #1 would be -3/5

Slope is y1-y2/X1-x2 therefore 1 is 4+1/2-5, -5/3 2 is -9/2 3 is -12-6/-23-(-15)... -18/-23+15 therefore 3 is 18/8 or 9/4 reduced.

Help please geometry !

Leona [35]

If you use the same technique from the first question, you can do:

5x+2=3x+42
2x=40
x=20

For the rest of the questions, please use the same technique if they are vertical because I can't solve all of the questions for you sorry.

A cable 19 m long runs from the top of a utility pole to a point on the ground 10 m from the base of the pole. How tall is the u

Leviafan [203]

Answer:

16.2 m

Step-by-step explanation:

First, we can draw a picture. The cable goes from the top of the pole to the ground (with the pole on the right in my drawing), and the point on the ground is 10 m away from the base of the pole. This forms a right triangle, with the right angle being between the 10 m distance and the pole itself. We can then apply the Pythagorean Theorem, so

a²+b²=c², with c being the side opposite the right angle (the cable), getting us

10²+(length of pole)² = 19²

19²-10²=(length of pole)²

= 261

square root both sides to isolate the length of the pole

length of pole ≈ 16.2 m

X + p = q

expeople1 [14]

X=q-p
What you have to do is to rearrange the formula
x+p=q
All you have to do is to move “+q” to the other side of the formula. Doing so you also have to change the sign from “+” to “-“ so that your equation could be balanced
Hope this helps!!!!

A building is 2ft from a 10ft fence that surrounds the property. A worker wants to wash a window that is 14ft from the ground. H

Ronch [10]

Height of fence = 10 feet

Height of point where window needs to be washed = 14 feet

Distance between fence and building = 2 feet

Distance between fence and ladder = 10 feet

⇒ Distance between building and ladder = Distance between fence and building + Distance between fence and ladder

⇒ Distance between building and ladder = 2 + 10 feet

⇒ Distance between building and ladder = 12 feet

Now to determine the length of the ladder that goes over the fence, we can use the Pythagoras theorem, where perpendicular is represented by the height of the building, and base is represented by distance between the building and the ladder, and the length of the ladder represents the hypotenuse

So by Pythagoras theorem:

H² = P² + B²

⇒ Length of the Ladder² = Height of the Building² + Distance between Ladder and Building²

⇒ Length of the Ladder² = 14² + 12²

⇒ Length of the Ladder² = 196 + 144

⇒ Length of the Ladder² = 340

⇒ Length of the Ladder = √340

⇒ Length of the Ladder = 18.439..

⇒ Length of the Ladder = 18.4

Hence, the length of the ladder should be 18.4 feet
