PLEASE HELP ME SOMEONE

Mathematics
1 answer:
n200080 [17]3 years ago
5 0

Answer:

Option 2: 27 is the correct answer.

Step-by-step explanation:

Given functions are:

f(x) = x^2-2\\g(x) = 4f(x) - 1

As we can see that the function g(x) in written in terms of f(x), first of all we have to find g(x) by putting the value of f(x) in g(x)

So putting f(x) = x^2-2 in g(x)

g(x) = 4(x^2-2)-1\\= 4x^2-8-1\\=4x^2-9

As g(-3) has to be found, putting x=-3 in g(x)

g(-3) = 4(-3)^2-9\\= 4(9)-9\\=36-9\\=27

Hence

Option 2: 27 is the correct answer.

How does the story make you feel when you read it? This is the mood or "atmosphere." Tone is closely related, but with more emphasis on the writing. So if the words make you laugh but are overwhelmingly dark, the tone is "sarcastic" or "sardonic" and the mood is "dark" and "funny." Honestly, the terms are often interchangeable.

I don't know but this is all I know I'm sorry

An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled usin
GuDViN [60]

Answer:

<em>3 seconds</em>

Step-by-step explanation:

Complete question:

<em>An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled using h(t)=144-16t2. How many seconds will it take the object to reach the ground? 2 seconds 3 seconds 9 seconds 16 seconds</em>

<em></em>

Given the height of an object modelled by the expression;

<em>h(t)=144-16t²</em>

The object will reach the ground when h(t) = 0

Substitute into the formula

0 = 144 - 16t²

-144 = -16t²

144 = 16t²

Swap

16t² = 144

t² = 144/16

t² = 9

Square root both sides

√t² = ±√9

t = ±3secs

<em>Since the time cannot be negative, hence the object will reach the ground 3 seconds after</em>
