Answer:

a.) f(2) = 3

b.) if f(x) = 2

x=3

Step-by-step explanation:

Here you must notice that on the graph where x is 2, y or f(x) is at 3. This means that the answer where in the function of x, where the input 2, the output or y/f(x) is 3

And if the output is 2, the input is 3 as proven above.

Answer:

length of hypotenuse = 10 ft.

Step-by-step explanation:

by pythagorus theorem,

$h {}^{2} = b {}^{2} + p {}^{2}$

( where, h = hypotenuse, b = base , h = height )

so,

=》

$c {}^{2} = 6 {}^{2} + 8 {}^{2}$

=》

$c {}^{2} = 36 + 64$

=》

$c {}^{2} { = 100}^{}$

=》

$c = \sqrt{100}$

=》

$c = 10$

hence, hypotenuse = the 10 feet.

In the year 2000, the average cost of a computer could be modeled by the equation C = -5t2 + 750, where t is the number of years

elena55 [62]

Answer:

$\Delta C=-5t^2-250$

Step-by-step explanation:

Given:

The average cost of a computer in the year 2000 is given as:

$C=-5t^2+750$

The average cost of a computer in the year 2008 is given as:

$C=-10t^2+500$

Now, the difference in average cost between the years 2008 and 2000 can be calculated by subtracting the average cost in 2000 from the average cost in 2008.

Framing in equation form, we get:

Difference in average cost (ΔC) is given as:

$\Delta C=C_{2008}-C_{2000}\\\\\Delta C= (-10t^2+500)-(-5t^2+750)\\\\\textrm{Distributing the megative sign inside the second polynomial, we get:}\\\\\Delta C=-10t^2+500+5t^2-750\\\\\textrm{Grouping like terms, we get}\\\\\Delta C=(-10t^2+5t^2)+(500-750)\\\\\Delta C=-5t^2-250$

Therefore, the difference in the costs for a computer between 2008 and 2000 is $\Delta C=-5t^2-250$

PLEASE HELP !!!What is the distance between the tick marks on the number line? A number line going from 0 to 2 in increments of

jek_recluse [69]

Answer:

1/5 or A

Step-by-step explanation:

Hello. Please excuse the idiot above we do not know how he formed or why he speaks like a gorilla on crack. Anyways, we, humans, believe that 1/5 is the correct answer since their are 5 intervals between 0 and 1 between one of the tick marks is 1/5 since there are 5 intervals. I really hope you guys are human not this gorilla above us. I hope I made your day please rate 5 stars , add thanks and please mark brainliest. :)
