Answer:

Step-by-step explanation:

Fist let's have a look :

  • (AB) is parallel  with (CD) and there is a line crossing them both.

Now the first question : What is the size x ?

  • We notice that x and 53° are vertically opposite so they are corresponding angles
  • so the size of x is 53°

The second question : what is the size of y ?

  • We notice that y and 53° are alternate angles
  • so they are corresponding angles with same size
  • y=53°

The trick is to khow the situation where we have  corresponding angles

There were about 1.22 million Hispanic-owned businesses in 2012 and 1.73 million in 2017.
fredd [130]

Answer:

  f(t) = 1.22·(173/122)^(t/5)

Step-by-step explanation:

(a) An exponential growth (or decay) function can be written using the form ...

  f(t) = (initial value)·(ratio in period)^(t/period)

Here, we're given an initial value of 1.22, a growth ratio of 1.73/1.22 in a period of 5 years, so we can write the function as ...

  f(t) = 1.22·(173/122)^(t/5)

__

(b) In 2038-2012 = 26 years, the value of the function is ...

  f(26) = 1.22·(173/122)^(26/5) ≈ 7.50 . . . . million
