Step-by-step explanation:
i hope its correct and helful
Given that:
f(x) = -2x²-2x+10
f(2) = -2(2)²-2(2)+10
= -2(2*2) - 4 + 10
= -2(4) - 4 + 10
= -8 - 4 + 10
= -12 + 10
= -2 Ans.

Answer:
There are two ways to do this problem algebraically or trigonometrically.
Algebraically/geometrically
The ratios of the sides of a 30/60/90 tri. are x, x√3, 2x (short leg, long leg, hyp). Therefore, if the long leg is 6 'units'. then 6 = x√3. x = 6√3.
The hyp is 2x then the hypotenuse is 2(6√3) = 12√3, rationalizing is 12√3/3 = 4√3
Using Trig.
We can use sinx = y/r = opp/hyp. The long leg of 6 is opposite 60 degrees (pi/3).
Therefore, sin(pi/3) = 6/r =
r = 6/sin(pi/3) = 6/(√3/2) = 12/√3, when you rationalize you get 12√3/3 = 4√3
Answer:
15
Step-by-step explanation:
4 x __ = 12
the blank would be 3, once you did it on one side you have to do it on the other side too
5 x 3 = 15
Another way you can do it is by...
= 
solve for x (cross multiply)
Answer:
Hello there!
The answer to your question is :
<em>C: Finn needs 6 cups of sugar for 4 cakes.</em>
<em>D: Finn needs 1 1/2 cups of sugar for 1 cak</em>e.
Step-by-step explanation:
The graph clearly shows ( sides cups of sugar) (bottom number of cakes)
For sugar you need 6 cups to make 4 cakes
For sugar on the second question you need 1 1/2 cups of sugar to make 1 cake
Multiply 1 1/2 times 6 then divide and your answer is 4. That's 4 cakes out of 6 cups of sugar out of the original cups of sugar ( 1 1/2)
This is the confirmed answer I took the quiz and got 100%
Hopes this helps you!
