2+2=4, because 2 is made up of two ones and theres 2 2's which makes it 1+1+1+1=4

Step-by-step explanation:

Graph the data in the table. which kind of function best model the data? write an equation to model the dataa. linear; y = 2xb. quadratic; y = 2x^2c. exponential; y = 2 · 2^xd. exponential; y = 4 · 2^x

Looking at the possible answers, the only one that fits is D.

Let's first look at A: y = 2x
We know this doesn't work, since if you plug in 0 for x, y = 0, not 4.

Let's look at B: 2x^2
We know this doesn't work either, since if x is 0, y = 0, not 4.

Let's look at C: 2 × 2^x
We know this doesn't work, since if x = 0, y = 2:
$y = 2 \times {2}^{x} \\ 4 = 2 \times {2}^{0} \\ 4 = 2 \times 1 \\ 4 = 2$
This leaves D: 4 × 2^x:
$y = 4 \times {2}^{x} \\ 4 = 4 \times {2}^{0} \\ 4 = 4 \times 1 \\ 4 = 4$
It also works for (1,8) and (2,16):
$y = 4 \times {2}^{x} \\ 8 = 4 \times {2}^{1} \\ 8 = 4 \times 2 \\ 8 = 8$

$y = 4 \times {2}^{x} \\ 16 = 4 \times {2}^{2} \\ 16 = 4 \times 4 \\ 16 = 16$
The answer is D.

this isn t even a question lol, im just gonna take a small break from history and write whatever i wanna write. so idk why i was stressin do much about yesterday, i did like 3 history quizzes and got a and b s. i gotta get it to a c or b. I started animating again yesterday and i did it my own way. i made jenny meme and IT WAS AWWEESOOEE i shouldnt try to animate like someone else, i should have done it my own way. i got it done in 2 hours which is not like me... it takes me like a week. just because i say 2 hours doesnt mean i got it all sloppy

$\large\boxed{f(x)-g(x)=4x^3+2x^2+2x}$

Step-by-step explanation:

$f(x)=9x^3+2x^2-5x+4,\ g(x)=5x^3-7x+4\\\\f(x)-g(x)=(9x^3+2x^2-5x+4)-(5x^3-7x+4)\\\\=9x^3+2x^2-5x+4-5x^3-(-7x)-4\\\\=9x^3+2x^2-5x+4-5x^3+7x-4\qquad\text{combine like terms}\\\\=(9x^3-5x^3)+2x^2+(-5x+7x)+(4-4)\\\\=4x^3+2x^2+2x$

An ice cream shop offers 5 different flavors of ice cream and 9 different toppings. How many choices are possible for a single serving of ice cream with one topping?

Step-by-step answer

P Answered by PhD

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45
