<u><em>Answer is below</em></u>

Step-by-step explanation:

<em><u>-2 ×^2 - 4y +6</u></em>

<em><u>Evaluate simply means to form an idea of something</u></em>

<em><u>So Evaluate for x=−3,y=−2</u></em>

<em><u>−2(−3)2−(4)(−2)+6</u></em>

<em><u>−2(−3)2−(4)(−2)+6</u></em>

Can someone please answer A and B please?
marta [7]

2 bags

7 apples


A) Instead of a lets say:

a = 1, 2 , 3

If a =1  then, (you already know there are 2 bags) you have 1 apple in each bag, making total of 2 apples

If a =2 then you are having 2 apples in each bag making total of 4 apples

If a =3, 3 apples in each bag, making total of 6 apples

Conclusion:

2 * 1 = 2

2 * 2 = 4

2 * 3 = 6

See the difference & pattern here

Now lets do with a

2 * a = 2a


B) If a = 6

then,  2*6 = 12

lets continue from a =3

2*4=8

2*5=10

2*6=12

See the pattern again


Tip: Drawing making problem understand better.

What is sin -1(1/2) if the terminal side of 0 is located in quadrant 1.
kotykmax [81]

Answer:

30

Step-by-step explanation:

\sin^{-1}(\theta) is going to output a number in between \frac{-\pi}{2} and \frac{\pi}{2}.

Luckily you are looking for \theta in the 1st quadrant which is contained in the given interval above, so the answer just comes down to what the calculator returns from entering \sin^{-1}(\frac{1}{2}) in your calculator.

You may also use the unit circle.  sine value refers to the y-coordinate on there.

So you are looking for when the y-coordinate is 1/2 in the fist quadrant which is at 30 degrees.

Please help me with 1a, thanks
valkas [14]

Since 1A claims that the diagram is of a square, you can easily find the perimeter by multiplying just one side by 4, because the definition of a square says that all of its four sides are equal in length.

Take the left side, x and 4, and add them together, because both of these lengths add up to form the side of the square. You have found one side of the square, x + 4. Now multiply this side by 4 for the perimeter.

Perimeter is the length all around the figure, and since a square has 4 sides you would multiply one side by 4 to find the perimeter.

4(x + 4) is your expression for the perimeter of the square. You could probably solve 1B and 1C by substituting in 3 and 5 for x in the equation I've given you :)
