Answer:

13ft

Step-by-step explanation:

Kindly find attached a rough draft of the situation.

Step one:

Given data

The length of the slide represents the

Hypotenuse of the situation on the rough sketch

Angle =33°

Required

The height of the ladder which is the adjacent of the rough sketch represented by x

Step two:

Applying SOH CAH TOA

Cos θ= adj/hyp

Cos 33=x/15

0.84=x/15

Cross multiplying

x=0.84*15

x=12.6

To the nearest foot the ladder is 13ft tall

Answer:

19

Step-by-step explanation:

note that

(a + b)² = a² + b² + 2ab , that is

a² + b² + 2ab = (a + b)² ← subtract 2ab from both sides

a² + b² = (a + b)² - 2ab

           = 5² - 2(3)

           = 25 - 6

          = 19

On which interval is the function increasing? ​
sukhopar [10]

Answer:

b. (-1,0)\cup (1,\infty)

Step-by-step explanation:

The graph can be divided into 4 regions.

Region 1 is for x\in (-\infty,-1)

Region 2 is for x\in (-1,0)

Region 3 is for x\in (0,1)

Region 4 is for x\in (1,\infty)

So, for the region 1, the values of y goes on decreasing with increasing x. Therefore, the function is decreasing in the interval (-\infty,-1).

Now, for the region 2, the values of y increases with increasing x. So, the function is increasing in the interval (-1,0).

For the region 3, the the values of y goes on decreasing with increasing x. Therefore, the function is decreasing in the interval (0,1).

Now, for the region 4, the values of y increases with increasing x. So, the function is increasing in the interval (1,\infty).

Therefore, regions 2 and 4 are the regions when the function is increasing.

Hence, the correct option is b. (-1,0)\cup (1,\infty)
