Y= 3.5t+2
you spent 3.5 hours on each test
(3.5(4)+2= 16)
answer:
the decimal point shifts to the right to represent each multiplication by 10
Step-by-step explanation:
an example is 1.23*10
would give you 12.3 and if you multiply it by 100 it would give you 123
Answer:
4.3 or 4.29
Step-by-step explanation:
Since it's a right angle triangle, you can use trig functions to solve.
You already know that the side across from P is 2 and the hypotenuse is , so you can use cosine.
degrees, or 1.342 radians.
Then, put in your angle for your tangent.
Finally, round to the hundredth:
4.301 becomes 4.3
4.294 becomes 4.29
Of course, these should be about the same, but will be slightly different because we rounded when computing cosine and tangent earlier.
Answer:
As x gets bigger, y is now getting smaller.
Step-by-step explanation:
A fancy way to say this is that the function y = 2-x is what we get when we reflect y = 2x across the y-axis.
Answer:
(2, 4)
Step-by-step explanation:
The only point that satisfies the inequality is (2, 4).
(0, 5) : -0^2 +5 = 5 . . . . . not > 5
(1, 3) : -1^2 +5 = 4 . . . . . . 3 is not > 4
(2, 4) : -2^2 +5 = 1 . . . . . . 4 is greater than 1, so this point is in the solution set.
