Step-by-step explanation:

You have to use the Secant Segment theorem:

AB * AC = AD * AE

This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.

Now, setup an equation:

8(x + 8) = 4(30 + 4)

Simplify:

8x + 64 = 120 + 16

8x = 72

x = 9

2(4x-1)+3=7<br> i'm little confused on this

Ratling [72]

Answer:

x = $\frac{3}{4}$

Step-by-step explanation:

Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x

Now, you have 8x - 1 + 3 = 7

Seperate the 8x from the other numbers

8x = 1 - 3 + 7 ---> 6

8x = 6

Now simplify

x = $\frac{6}{8}$ <----- to reduce, divide the numerator and denominator by 2

Hence,

x = $\frac{3}{4}$

If the period of a sine function is the number of units before the cycle begins to repeat, why would the period of the regressio

Jlenok [28]

Answer:

This means that after going around the unit circle once (2π radians), both functions repeat. So the period of both sine and cosine is 2π . Hence, we can find the whole number line wrapped around the unit circle.
