Consider the two expressions 5x + 2 and 5(x+2).<br> (I’m sorry If the picture is unclear)
worty [1.4K]

Answer:

Step-by-step explanation:

x = 3                    5x + 2                 5(x+2)

                        = 5(3) + 2             = 5(3 + 2)

                        = 15 + 2                = 5(5)

                        = 17                      = 25

x = 6                    5x + 2                 5(x+2)

                        = 5(6) + 2             = 5(6 + 2)

                        = 30 + 2               = 5(8)

                        = 32                     = 40

For a right triangle. one angle is 20°. what are the other two angles ?​
Aleksandr [31]

Answer:

A triangle equals to 180. Given that it is a right triangle, one angle should be 90.

So, 90+20 = 110

180-110= 70

Therefore, the other two angles are 90 and 70.

Plot another sin function of 20% higher frequency over the same range.
Ostrovityanka [42]

Step-by-step explanation:

The frequency of sine function is given by the number of periods in a given range. For example:

  • Frequency for sin(x) is 1 in the interval [0,2\pi].

This means that, if we want another sine function with frequency 20% higher, we need that function to have a frequency of 1.2 in the interval [0,2\pi].

To be easier to see we will consider interval [0,10\pi] instead of [0,2\pi]. In this interval sin(x) has 5 periods, therefore our new sine function should have 6 periods.

Finally, as we can see in the graph, the function sin(\frac{6}{5}x ) (in blue) has a frequency 20% higher than sin(x) (in red). This can be easily seen counting the number of periods between 0 and 10\pi for both functions. 5 for sin(x) and 6 for sin(\frac{6}{5} x).
