If f(x)=9-4x^2 Find<br>a) f(-2) <br>b) f(-3) f(3) <br>c) x such that f(x) = 0​
Lana71 [14]

Answer:

see explanation

Step-by-step explanation:

(a)

To evaluate f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = 9 - 4(- 2)² = 9 - 4(4) = 9 - 16 = - 7

(b)

Similarly substitute x = - 3 and x = 3 into f(x)

f(- 3) = 9 - 4(- 3)² = 9 - 4(9) = 9 - 36 = - 27

f(3) = 9 - 4(3)² = 9 - 4(9) = 9 - 36 = - 27

(c)

let f(x) = 0 , then

9 - 4x² = 0 ( add 4x² to both sides )

9 = 4x² ( divide both sides by 4 )

\frac{9}{4} = x² ( take the square root of both sides )

± \sqrt{\frac{9}{4} } = x

± \frac{\sqrt{9} }{\sqrt{4} } = x

± \frac{3}{2} = x

That is x = - \frac{3}{2} or x = \frac{3}{2}

I need help finding the missing information for a rhombus
professor190 [17]

Answer:

  • ∠BCE = 28°
  • ∠ABE = 62°
  • ∠BAD = 56°

Step-by-step explanation:

The diagonals of a rhombus bisect each other at right angles, and bisect each of the vertex angles. Of course, adjacent vertex angles are supplementary.

Assuming E is where the diagonals cross, then we have ...

  ∠ABE = 124°/2 = 62°

  ∠BCE = 90° -62° = 28°

  ∠BAD = 2·28° = 56° . . . (= 180° -124°)
