Answer:

13. x=0, x= -4

14. NO EXCLUDED VALUE

Step-by-step explanation:

13. set the denominator to equal to 0 = x^2 + 4x = 0

factor the expression x × (x + 4) = 0

separate into possible cases = x = 0 and x = -4

state the excluded value = x = 0 and x = -4

14. set the denominators equal to 9 = x^2 +81 = 0

the statement is false for any value if x = x € ℝ

If f(x) = (1/9)(9^x) what is f(3)

TiliK225 [7]

Answer: The required value of f(3) is 81.

Step-by-step explanation: We are given the following function :

$f(x)=\left(\dfrac{1}{9}\right)9^x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We are to find the value of f(3).

Substituting x = 3 in equation (i), we get

$f(3)\\\\\\=\left(\dfrac{1}{9}\right)\times9^3\\\\=9^2\\\\=81.$

Thus, the required value of f(3) is 81.

In a right triangle STR, angle T and R are complementary angles. The value of cos(T) is 9/41. What is the value of sin(R)?

alex41 [277]

Answer: C) 9/41

Step-by-step explanation: From the description, angle S is the right angle. Which means that angles T and R are complementary (they sum to 90 degrees). Because they are complementary, this means the cosine of one angle is equal to the sine of the other angle. If cos(T) is 9/41, then so is sin(R).
