Answer:
It was not my intention to post that answer, as it does not solve the question, but hope it helps somehow.
Step-by-step explanation:
You want to verify this identity.
The common denominator is
Solving the first and second numerator:
Now we have
Once
Also, consider the identity:
That last claim is true.
Translation of the graph:
y = ( x + 3 )² - 2 to y = ( x - 2 )² + 2
The equations are in the form: y = a ( x - h )² + k
- 2 → 2 ( up 4 )
- 3 → 2 ( 5 to the right )
Answer:
The translation is
A ) up 4 and 5 to the right
Answer:
Step-by-step explanation:
<u>Given the scale factor:</u>
Since the cylinders are similar, the other dimensions should have same scale factor of 1/3.
<u>The volumes are:</u>
<u>Ratio of volumes is the cube of the scale factor, as the volume is the product of 3 dimensions:</u>
- v/x = k³
- 67/x = (1/3)³
- x = 67*27
- x = 1809 cm³
Answer:
A horizontal line; a melting ice cube.
Step-by-step explanation:
A constant interval appears as a horizontal line. The graph in the interval has a slope m = 0.
Here's an example of a constant interval.
You take an ice cube from the freezer and place it in a container on the counter.
The temperature of the ice cube is -5 °C. The ice cube will warm to 0 °C, and then it will start to melt. While it is melting, the temperature is constant at 0 °C.
When the ice has completely melted, the water will start warming to room temperature.
A plot of <em>temperature vs. time</em> would look something like the graph below.
The interval AB, where the ice is melting, is a constant interval.
Answer:
cosA = -
Step-by-step explanation:
Using the double angle identity
cos2A = 2cos²A - 1 , then
cosA = 2cos²( ) - 1 , that is
cosA = 2 × ( )² - 1
= 2 × - 1
= -
= -
