Answer:

The answer in the procedure

Step-by-step explanation:

Let

m1 and m2 ----> the slopes of the lines constructed

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

therefore

To verify if the lines constructed are perpendicular

Multiply their slopes

if m1*m2=-1 ------> the lines are perpendicular

√ 25 –2√3 + √27 +2√ 9 Express in simplified radical
gregori [183]

Answer:

The expression in simplified radical  form is:

√ 25 –2√3 + √27 +2√ 9 = 11 + √3

Step-by-step explanation:

Given the expression

√ 25 –2√3 + √27 +2√ 9

as

√ 25 = 5

√27 = 3√3

2√9 = 6

so the expression becomes

√ 25 –2√3 + √27 +2√ 9

= 5 - 2√3 + 3√3 + 6

= 11 + √3

Thus, the expression in simplified radical  form is:

√ 25 –2√3 + √27 +2√ 9 = 11 + √3

Help Please, anyone good at domain values of composite functions.
Delicious77 [7]

Answer:

second choice

Step-by-step explanation:

(f \circ g)(x) =

= f(g(x))

= f(-7x + 7)

= \sqrt{-7x + 7 + 3}

= \sqrt{-7x + 10}

Let x = 5:

(f \circ g)(5) = \sqrt{-7(5) + 10}

(f \circ g)(5) = \sqrt{-35 + 10}

(f \circ g)(5) = \sqrt{-25}

Since using x = 5 gives the square root of a negative number, 5 is not in the domain of the composition of the functions.

Answer: second choice
