Answer:

No, unless the function decides to follow a different pattern. See more explanation below.

Step-by-step explanation:

He is wrong, the table doesn't tell us what happens at x=6.

It does tell us the following:

1) When x=-4, f(x)=6.

2) When x=-2, f(x)=3.

3) When x=0, f(x)=-1.

4) When x=2, f(x)=-4.

So maybe he got it the x and f(x) value switched in his brain.

Because according to 1) x=-4 when f(x)=6.

If the points keep having x increase while y decreases, then every x>2 will have a y less than -4 correspond to it.

In quadrilateral ABCD, BN and DM are drawn perpendicular to AC such that BN = DM. Prove that O is the midpoint of BD
GaryK [48]

Answer:

Step-by-step explanation:

Given :

In the given quadrilateral ABCD,

BN and DM are the perpendiculars drawn to AC such that,

BN = DM

To prove:

Point O is the midpoint of segment BD.

Or

OD = OB

Solution:

In ΔOMD and ΔONB,

∠MOD ≅ NOB [Vertical angles]

∠M ≅ ∠N ≅ 90° [Given]

Therefore, by AA property of similarity,

ΔOMD ~ Δ ONB

Therefore, their corresponding sides will be proportional,

\frac{DM}{BN}=\frac{OD}{OB}

Since BN = DM,

OD = OB

Hence O is the midpoint of BD.

Find the surface area of the figure
Maurinko [17]

Answer:

Step-by-step explanation:

circumference of cylinder = πd = 5π  in

lateral area of cylinder = 5π×9 = 45π in²

Each colored face has a matching face on the other side of the figure.

green areas = 2(17×15) = 510 in²

blue areas = 2(12×17) = 408 in²

gray areas = 2(5×6) = 60 in²

yellow areas = 2(5×12) = 120 in²

red areas = 2(12×15) = 360 in²

total surface area = 45π + 510 + 408 + 60 + 120 + 360 ≅ 1,599.37 in²
