Find f(–2) for the function f(x) = 3x2 – 2x 7. −13 −1 1 23
pickupchik [31]

Answer:

16

Step-by-step explanation:

f ( x ) = 3x² - 2x

To find : f ( - 2 )

f ( - 2 ) = f ( x )

Here,

x = - 2

f ( - 2 ) = 3 ( - 2 )² - 2 ( - 2 )

           = 3 ( 4 ) - 2*( - 2 )

           = 3*4 + 4

           = 12 + 4

f ( - 2 ) = 16

Soloha48 [4]

Answer: Yes they could.

Step-by-step explanation:

The two pairs of sides given are proportional: 3/7 : 9/21

The two triangles have the side:side ratio, meaning they are similar

Because they are similar, their hypotenuses <em>could</em> lie along the same line, not guaranteed, but possible.

Hellp meee please I’m about to fail this subject!
elixir [45]

Answer:

So first you have to do 12-2 since it's in parenthesis. It is 10. 5+4 is 9, and 9 times 10 is 90. 3 squared is 9, then you divide 90 by 9. The answer is 10.

Pls tell me some answers for this
devlian [24]

Answer:

∠B ≈ 56.25°

Step-by-step explanation:

Since the triangle is right use the cosine ratio to solve for B

cosB = \frac{adjacent}{hypotenuse} = \frac{BC}{AB} = \frac{5}{9}, thus

B = cos^{-1}(\frac{5}{9} ) ≈ 56.25°
