If you ended at 7:43 and 37 minutes passed then:
43 - 37 = 6
7:06 was your start time

Starting time:
Ending time: 7:43

Elapsed time: 37 minutes.

We are 43 minutes into 7 o'clock. 37 minutes ago, it would have been 43 - 37, or 6 minutes.

The starting time is 7:06

Emily took 300 US dollars to the bank to exchange it for Canadian dollars. The exchange rate on that day was 1.25 Canadian dolla
Paha777 [63]

Emily wanted to exchange her 300 US Dollars for Canadian Dollars.

The exchange rate for it was 1.25 Canadian Dollars for 1 US Dollar.

This means that 1 US Dollar = 1.25 Canadian Dollars.

So if we were to follow this pattern,

2 US Dollars = 2 × 1.25 = 2.5 Canadian Dollars

3 US Dollars = 3 × 1.25 = 3.75 Canadian Dollars

4 US Dollars = 4 × 1.25 = 5 Canadian Dollars

So for 300 US Dollars, we'll need to multiply 300 by 1.25.

300 US Dollars = 300 × 1.25 = 375 Canadian Dollars.

Hope it helps. :)

Answer:

s(x) is t(x) ...

  • horizontally compressed by a factor of 2,
  • reflected across the y-axis, and
  • translated downward 5 units.

Domain and Range

  • t(x) has a domain of x ≤ 0, and a range of y ≥ 0.
  • s(x) has a domain of x ≥ 0, and a range of y ≥ -5.

Step-by-step explanation:

t(x) is the square root function reflected across the y-axis and compressed horizontally by a factor of 2. That is, in f(x) = √x, the x has been replaced by -2x.

s(x) has the function t(x) <em>reflected back across the y-axis</em> and compressed horizontally by another factor of 2. It is also <em>translated downward by 5 units</em>, so that its origin (vertex) is at (0, -5).

_____

The graph shows you the domain and range of s(x). The domain is all numbers to the right of x=0, including x=0. That is ...

  domain: x ≥ 0

The range is all numbers -5 or above:

  range: y ≥ -5

___

For t(x), the argument of the square root function must not be negative, which means the value of x cannot be positive.

  domain: x ≤ 0

For non-negative values of radicand, the t(x) function will have non-negative values. So, the range is ...

  range: y ≥ 0

_____
