Answer:

t(99)= -2.89

Step-by-step explanation:

-To places after the decimal point is equivalent to rounding off to the nearest hundredth.

-To round off to the nearest hundredth, we check the thousandths digit:

If the thousandths digit is less than5, we round down to the previous hundredth.
If the thousandths digit is greater than 4, we round up to the next hundredth:

Hence, $-2.8888\approx-2.89$

Which graph of f(x) satisfies the conditions lim f(x) = -4 and lim f(x) = 0?<br> X2-<br> X-2+<br> Y

Mkey [24]

The graph of f(x) satisfies the conditions lim f(x) = -4 and lim f(x) = 0 is the graph attached.

<h3>What is one-sided limit for function?</h3>

It should be noted that the limit from one side is simply when the side of the functions is used with respect to the point of interest.

For this graph, the point x = 2 on the left from the point x = 2 lies a ray. The prediction here is that the value of function on x = 2 us the value that the line gives for y.

Therefore, the graph of f(x) satisfies the conditions lim f(x) = -4 and lim f(x) = 0 is attached.

Find the inverse of the following function. Then prove they are inverses of one another.

solmaris [256]

Answer: $\dfrac{x^2+1}{2}$

Step-by-step explanation:

Given

$f(x)=\sqrt{2x-1}$

We can write it as

$\Rightarrow y=\sqrt{2x-1}$

Express x in terms of y

$\Rightarrow y^2=2x-1\\\\\Rightarrow x=\dfrac{y^2+1}{2}$

Replace y be x to get the inverse

$\Rightarrow f^{-1}(x)=\dfrac{x^2+1}{2}$

To prove, it is inverse of f(x). $f(f^{-1}(x))=x$

$\Rightarrow f(f^{-1}(x))=\sqrt{2\times \dfrac{x^2+1}{2}-1}\\\\\Rightarrow f(f^{-1}(x))=\sqrt{x^2+1-1}\\\\\Rightarrow f(f^{-1}(x))=x$

So, they are inverse of each other.

Simplify (-7/8)(-3/4).

murzikaleks [220]

Answer:

<h2>21/32</h2>

Step-by-step explanation:

-7/8 × -3/4 = 21/32

-7 × -3 = 21

-8 × -4 = 32

21/32

<u><em>IMPORTANT: This number is not negative, because a negative times a negative is a positive.</em></u>

By the way, if you didn't know how to arrive at the fraction here's how.

First, Address input parameters & values.

Input parameters & values: The decimal number = 0.65625. Then, write it as a fraction

0.65625/1

Multiply by 100000 both the numerator & denominator

(0.65625 x 100000)/(1 x 100000) = 65625/100000

65.625% = 65.625/100 or 65625/100000

Find LCM (Least Common Multiple) for 65625 & 100000.

3125 is the LCM for 65625 & 100000

Divide by 3125

65625/100000 = (65625 / 3125) / (100000 / 3125)

= 21/32

I'm always happy to help :)
