Answer:
Step-by-step explanation:
This triangle is a 30°-60°-90° triangle, so you should always remember the rule shown in the picture. Because y is across from the 60° angle, it will be 
. 3 is x because it is across from the 30° angle, so y will be .
The answer is C but not sure about it please double check it
Thank you
I hope it’s help you
The function y=x2 or f(x) = x2 is a quadratic function, and is the parent graph for all other quadratic functions. The shortcut to graphing the function f(x) = x2 is to start at the point (0, 0) (the origin) and mark the point, called the vertex.
The slope of the line passing through the points (-4 , 0) and (7 , 0) is 0 ⇒ 3rd answer
Step-by-step explanation:
The formula of the slope of a line is 
where 
and 
are two points on the line
To find the slope
- Let one of the two points to be
- Let the other point
- Substitute them in the formula of the slope
- Calculate the value of m
∵ The line passes through points (-4 , 0) and (7 , 0)
∴ 
= -4 and 
= 7
∴ 
= 0 and 
= 0
- Substitute these values in the formula above
∴ 
∴ m = 0
The slope of the line passing through the points (-4 , 0) and (7 , 0) is 0

Answer:
The answer to this question is D: None of the above
Step-by-step explanation:
From the example given in the question, this is a bad way of data sampling. The example in the question is a typical Voluntary response sample. In this type of sampling, the researcher creates a request as the case may be in the example through television, and ask for members of a population to join. Thus people then choose to be part of the sample or not. In this type of sampling, the respondents tend to have alike opinion in contrast to the rest of the population. This therefore makes voluntary response sample kind of bias.
