Answer:
Alcohol intake
Step-by-step explanation:
The Independent variable also called the predictor variable may be described as the treatment which is given a subject or factors which is expected to induce a change in our measured variable which is called the predicted or dependent variable. During research, the test various factors which are expected to cause a change are the independent variable, whereas, the variable which is measured as a result of the changes caused due to the different independent variables is the dependent variable. In the scenario above, we wish to measure braking speed after the subjects have been given a certain ounce of alcohol, this ounce of alcohol is the treatment which is expected to cause a variation in the braking speed of the participants. Hence, alcohol intake is the independent variable while braking speed is the dependent variable.
Let U=(1,2,3,4,5,6,7,8) A={1,3,5,7} B={1,3,5,7} C={5,8} D={2,5,8}. What is the subset
nikitadnepr [17]
U={1,2,3,4,5,6,7,8}; A={1,3,5,7} = B; C={5,8}; D={2,5,8}
All are subset of U
A is a subset of B & vice versa
C is a subset of D, but neither C nor D are subset of A or B
The correct answer is the option "B":
B.(-x-6i)(x-6i)
Explanation
You must keep in mind the following:
1. By definition, a complex number has the following form:
a+bi
"a" is the real part and "b" is the imaginary part.
2. i²=-1
3. Then,you have:
(-x-6i)(x-6i)=(-x²+(6i)²)=-x²-36
4. Therefore, the answer is: (-x-6i)(x-6i)
I'm guessing that you know about 45-45-90 and 30-60-90 triangles.
In 45-45-90 triangles, the legs are in a ratio such that the hypotenuse is
times the legs.
In 30-60-90 triangles, the legs are in a ratio of 1:
:2
In the picture given we have been given a value of the side of the 45-45-90 triangle. We can deduce that the value of the hypotenuse is 9
because of the ratio of the sides of a 45-45-90 triangle.
The 30-60-90 triangle shares the same hypotenuse, and so we now know a value of one of its sides as well. The ratio of the side of value 'x' and the hypotenuse is
: 2
We can create an equation to solve for x using these ratios:
= 
Cross multiply:
2x = 9
x =
