Yesenia has a 13 ft ladder that she placed against a
wall. How far up the wall will the ladder reach when the
base of the ladder is 5 ft from the wall?

Answers

Answer:

12 ft

Step-by-step explanation:

Using formula (pythagorean theorem)

a² + b² = c²

Where :

13 = c

and 5 = a

5² + b² = 13²

25 + b² = 169

169 - 25 = b²

144 = b²

Sq root b = 12

It will reach up 12 ft.

Answers

Answer: The error is the number of sides, it should be 9 sides and not 25. Correct is 1 260 degrees

Step-by-step explanation:

The error is the number of sides, it should be 9 sides and not 25.

Polygon sum of interior angles formula: 180 x (n-2)

So here n = 9 (sides)

180 x (9-2)

180 x 7 = 1 260 degrees

Answer:

sum of interior angles = 180 * n - 2

n = number of sides

in this case, the shape has 9 sides so n = 9

so the correct answer should be

= 180 * (9-2)

= 180 * 7

= 1260

On the line that passes through point C, mark a point D that is distinct from point C. Use the slope formula along with coordinates of points to find the slopes of and . Show your work.

Answers

Answer:

PLATO

Step-by-step explanation:

Answer:

The coordinates of point D will vary based on the point location, but the resulting slope of the line through points C and D will be the same.

A  =  (-3, 3), B = (-1,-1)

Slope of AB  =  (YB−YA) / ( XB –XA) =−1−3 / −1−(−3)= − 4 / 2= −2

D =  (-1,6), C = (1,2)

Slope of DC  =  (YC−YD) / (XC−XD)= 2 – 6 / 1−(−1)=−4 / 2=−2

Step-by-step explanation:

does 4(x+1)=2x+4 have a solution

Answers

Answer: Yes, x = 0

Step-by-step explanation:

To solve for x, we will simplify things by distributing the 4 to the (x + 1) term. This means that our new equation will be

4x + 4 = 2x + 4

Now that we have our new equation, we will isolate x by subtracting 4 from both sides. After this, we will end up with

4x = 2x

At first glance, this may seem like no solution. What number has the same value when multiplied by 2 and by 4? Well, there infact is one. This can be shown when we subtract both sides by 2x to keep x on one side, and get

2x = 0

Divide by both sides to isolate x, and you get x = 0/2 = 0.

Thus, x = 0.
