Answer:

122.6 m

Step-by-step explanation:

Shadow cast by the man = 3.1 m

Height of the man = 1.9 m

Shadow cast by the lighthouse = 200 m

Height of the lighthouse = x

If two shapes are similar, the ratio of their corresponding sides would be equal.

Therefore,

x/1.9 = 200/3.1

Multiply both sides by 1.9

x = (200*1.9)/3.1

x = 122.6 m (nearest tenth)

The lighthouse is 122.6 m tall

If a(x)=2x-4 and b(x) =x+2, which of the following expressions produces a quadratic function?

ZanzabumX [31]

Answer:

$(ab)(x)$

Step-by-step explanation:

The complete question in the attached figure

we have

$a(x)=2x-4\\b(x)=x+2$

we know that

(ab)(x) is equal to the product of a(x) and b(x)

$(ab)(x)=(2x-4)(x+2)$

Applying distributive property

$(ab)(x)=2x(x)+2x(2)-4(x)-4(2)$

$(ab)(x)=2x^2+4x-4x-8$

$(ab)(x)=2x^2-8$

This is a quadratic equation

The other expressions not produce a quadratic equation
