Answer:
350 MPH
Step-by-step explanation:
600-200+50-100=350
The pythagorean theorem states: a² + b² = c²
Where c is the longest side (hypotenuse).
So we plug in and solve for the third side "b".
a = 12, c = 13, so:
12² + b² = 13²
144 + b² = 169
b² = 169 - 144
b² = 25
b = 5
We can double check the pythagorean theorem to make sure:
12² + 5² = 13²
144 + 25 = 169
So the unknown side is definitely 5.
The quadratic term is 2x^2.
Think about it this way: 0.4 is read as what?
It's read as "four tenths".
This means that it can also be said as "four out of ten".
So, 0.4 into a fraction is "4/10".
Now, this fraction can be reduced, so what is the greatest common factor of 4 and 10?
Factors of 4: 1,2,4
Factors of 10: 1,2,5,10
So the greatest common factor is 2.
So, if you divide both 4 and 10 by the greatest common factor to get (4/2) = 2 and (10/2) = 5.
So, the reduced fraction would end up being 2/5.
When you divide 2 by 5, you get 0.4, if you want to check.
Answer:
look at each equation take equation I for example y = 2x then look at each table take the x value plug it in for the equation and see if you get the y value if you don't move on. so on this instance y = 2x I'm just going to plug in 2 * -2 gives me - 4, 2 * - 1 gives me -2, 2 * 0 gives me 0, 2 * 1 gives me 2 so the answer to table c is table c matches with equation i. keep doing that on your own and you should be able to get the rest
