The correct answer is B

Answer:

B) radical2/2

Step-by-step explanation:

To find the answer, you can A., either type this in a calculator, or B., use the unit circle.

When we observe the unit circle, we can see that the 45* angle is in Quadrant 1, and that the matching radian is pi/4, and the corresponding coordinates are (radical2/2, radical2/2).

So, sin(45*) is B) radical2/2.

Note that sin(θ) means the y-value of the angle's coordinates, cos(θ) normally means the x-value of the angle's coordinates..

What is the axis of symmetry of the function f(x)= -(x+9)(x-21)
Vinil7 [7]

Answer:

The axis of symmetry is x = 6

Step-by-step explanation:

To find this, first find the two x-intercept values and then take the average. This will always be the line of symmetry.

x + 9 = 0

x = -9

x - 21 = 0

x = 21

Now take the average of these two numbers.

(-9 + 21)/2

12/2

Subtract -7n +2 from 2n - 1
Irina18 [472]
2n - 1    -      -7n + 2     You combine like terms with subtracting
2n - 7n = -5n
-1 - 2 = -3
So -7n + 2     -     2n - 1 = -5n - 3

What is 5.8x10^6 seconds in minutes
Troyanec [42]
Let x be the number of minutes of 5.8*10^6 seconds.
Each minute is made of 60 seconds. Let's then use the rule of three:

60 seconds --> 1 minute
5.8*10^6 --> x minutes

x = (5.8*10^6)*1 / 60
x ≈ 96,666.66 minutes.

So 5.8*10^6 seconds is about 96,666.66 minutes.

Hope this Helps! :)
