cos and sec can be found
The requried simplified expression is 1 / cosØ, which is equivalent to secØ. The correct option is secØ.
Let's simplify the given expression and see which of the provided options match:
We are given the expression √(1 + tan²Ø).
Now, recall the trigonometric identity: tan²Ø = sin²Ø / cos²Ø.
Substitute this identity into the expression:
√(1 + sin²Ø / cos²Ø)
Next, find a common denominator for the fraction inside the square root:
√((cos²Ø + sin²Ø) / cos²Ø)
Since cos²Ø + sin²Ø = 1 (as per the Pythagorean trigonometric identity), the expression becomes:
√(1 / cos²Ø)
Now, we can take the square root of 1 and cos²Ø separately:
√1 / √cos²Ø
Simplify:
1 / cosØ
The simplified expression is 1 / cosØ, which is equivalent to secØ.
Therefore, the correct option is: secØ.

Considering the slope of the lines, it is found that the lines going through the points are neither parallel nor perpendicular.
When are lines parallel, perpendicular or neither?The slope, given by change in y divided by change in x, determines if the lines are parallel, perpendicular, or neither, as follows:
If they are equal, the lines are parallel.If their multiplication is of -1, they are perpendicular.Otherwise, they are neither.In this problem, the slopes are given as follows:
m1 = (5 - 3)/(-2 - 8) = -2/10 = -1/5 = -0.2.m2 = (-10 - (-5))/(-1 -(-2)) = -5/1 = -5.The multiplication is of 1, not -1, hence they are neither parallel nor perpendicular.

The perimeter of a rectangle is 34 cm. The length is 1 cm longer than the width. What is the length of the longest side of the rectangle?
Answers
Answer: 9 cm
Step-by-step explanation:
The formula for the perimeter of a rectangle is [tex]2l+2w=P[/tex]
Where
l is the length
w is the width
and P is the perimeter (34)
Because the length is 1 cm longer than the width instead of representing the length is l we can use w+1
Sub in the known values and solve
Step 1: Simplify both sides of the equation with the Distributive Property
[tex]2(w+1)+2w=34\\(2)(w)+(2)(1)+2w=34\\2w+2+2w=34\\(2w+2w)+(2)=34\\4w+2=34\\[/tex]
Step 2: Subtract 2 from both sides.
[tex]4w+2-2=34-2\\4w=32[/tex]
Step 3: Divide both sides by 4.
[tex]\frac{4w}{4}=\frac{32}{4} \\w=8[/tex]
Step 4: Add 1 to w to find the length of the longer side
