1 answer:

4 0

$\sin(x) = \cos(90-x) \frac{sin(x)}{cos(90-x)} = 1\\\prod_{n=1}^{89}\tan(n) = \frac{\sin(1)}{\cos(1)} \cdot \frac{sin(2)}{cos(2)}...\frac{sin(89)}{cos(89)} = 1$

Lisa [10]

Answer:

100% = 30. There are 30 students in Mr.Fulton's class

Step-by-step explanation:

If we have 12 as 40%, we divide it by 2 to get the base value which is 6=20%.

Now we multiply the base by 5 so 20% x 5= 100% and 6 x 5 equals 30. so 100% = 30

Please show me how to start this question but don't give me the answer

Natalija [7]

To make the input-output table, we need to plug in the given vaues of x's in the equation to get their corresponding values of y.

Let's plug in x = -2 in y = 6x +5. So,

y = 6( -2) + 5 = -12 + 5 = -7

Similarly for x = 0, y= 6(0) + 5 = 5

For x = 1, y = 6(1) + 5 = 6 + 5 = 11

For x = 4, y = 6(4) + 5 = 24 + 5 = 29

For x= 5, y = 6(5) + 5 = 30 + 5 = 35.

I am attaching the input -output table from the above result.

Hope this helps you!
