9 cm
OLEGan [10]

Answer:

∴ ∠BAD = sin^{-1}(0.2044) = 11.8°

Step-by-step explanation:

i) AD = 9 cm

ii) DC = 3 cm

iii) ∠BCD = 35°

iv) Since AB is parallel to DC and ∠ABD = 90°  then we can conclude that ∠BDC = 90°.

v) \frac{BD}{DC}  =  \frac{BD}{3\hspace{0.1cm}cm}  = tan(35) = 0.6128      ∴ BD  = 3 \times 0.6128 = 1.84 cm

vi) ∴ sin(∠ BAD ) = \frac{BD}{AD}      ⇒     sin(∠ BAD ) = \frac{1.84}{9} = 0.2044

     ∴ ∠BAD = sin^{-1}(0.2044) = 11.8°

The functions f and g are defined as follows.
g100num [7]

Answer:

f(-5)=-16\\g(2)=-11

Step-by-step explanation:

By definition, a relation is a function if and only if each input value have one and only one output value.

The input values are the x-values and the output values are the y-values.

Given the function f(x):

f(x)=3x-1

You need to substitute x=-5 into this function:

f(-5)=3(-5)-1

And now you must evaluate in order to find the corresponding output value.

You get:

f(-5)=-15-1\\\\f(-5)=-16

The function g(x) is:

g(x)=-2x^2-3

Then, you need to substitute x=2 in the function:

g(2)=-2(2)^2-3

And  finally you must evaluate in order to find the corresponding output value. This is:

g(2)=-2(4)-3\\\\g(2)=-8-3\\\\g(2)=-11
