Step-by-step explanation:

f(0)=-2(0)-9=0-9=-9

f(1/2)=-(1/2)-9=-1/2 -9=-19/2

f(-2)=-2(-2)-9=4-9=-5

Answer:

  • f(0) = -9
  • f(1/2) = -10
  • f(-2) = -5

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

<u>Question One. Identify the value of f(0)</u>

f(x) = -2x - 9

f(0) = -2(0) - 9

f(0) = 0 - 9

f(0) = -9

<u>Question Two. Identify the value of f(1/2)</u>

f(x) = -2x - 9

f(1/2) = -2(1/2) - 9

f(1/2) = -1 - 9

f(1/2) = -10

<u>Question Three. Identify the value of f(-2)</u>

f(x) = -2x - 9

f(-2) = -2(-2) - 9

f(-2) = 4 - 9

f(-2) = -5

Hope this helps!! :)

Consider angle θ in Quadrant II, where sinθ = 4/5 . What is the value of cosθ?
Kay [80]

Answer:

3/5

Step-by-step explanation:

sin theta=opposite/hypotenuse

4/5=opposite/hypotenuse

therefore opposite=4 and hypotenuse=5

for adjacent

using pythagoras theorem

a^2+b^2=c^2

opposite^2 + adjacent^2 =hypotenuse^2

4^2 + adjacent^2 =5^2

16 + adjacent^2 =25

adjacent^2 =25-16

adjacent =\sqrt{9

adjacent=3

cos theta=adjacent/hypotenuse

=3/5

therefore the value of cos theta is 3/5
