Answer:
The length is 7.2 feet.
Step-by-step explanation:
It is a ratio of 10:18. Therefore you can simplify the ratio to 18/10 or 1.8. This then becomes 4 (width) times 1.8, or 7.2 feet. :)
Answer:
Step-by-step explanation:
First of all you have to put the zeros into factor form.
y1 = (x + 2)(x - 5)
Notice that the x changes sigh. You say that the zeros are -2 and 5. To get y1 to go to zero, you must make x the opposite sign of what you are given.
Now you have to expand the factored form to get the standard form
y = x^2 + 2x - 5x - 10
y = x^2 - 3x - 10
That's not the right answer.
f(0) = 30 but you have - 10 at the end so you have to multiply the factored form by - 3
-3(f(x)) = -3(x + 2)(x - 5)
-3(f(x)) = -3(x^2 - 3x - 10)
f(x) = -3x^2 + 9x + 30
f(0) = -3(0)^2 + 9(0) + 30
f(0) = 30
The quadratic still has roots of (x +2)(x - 5) but that 3 makes the y intercept = 30.

Answer:
a) The subset consists of all the outcomes where your friend loses or there is a tie.
d) The subset consists of all the outcomes where you do not lose.
Both are correct.
Step-by-step explanation:
The subset A= { 1,3,4,6,7,9} removes 2,5 and 8 from the sample space of the game. Those three numbers are the ones for which your friend wins, therefore, the subset consists of all outcomes for which you either win (your friend loses) or there is a tie.
Checking the given alternatives, there are actually two correct ones. Alternatives a) and d) describe the same sample space (you not losing = your friend not winning).
Therefore, the two possible answers are:
a) The subset consists of all the outcomes where your friend loses or there is a tie.
d) The subset consists of all the outcomes where you do not lose.
Answer:
f(x)=7x-2
when x=5
f(5)=7×5-2=35-2=33
when x=-2
f(-2)=7×-2-2=-14-2=-16
other are similar to this
