1 answer:
Answer:
5a) 2 sides are equal to each other
5b)
6) 16
Step-by-step explanation:
5b) I'm assuming that in this question you are trying to find the hypotenuse? So you use the pythagorean theorum, which is a^2+b^2=c^2. c represents the hypotenuse, so it would be 10^2+10^2=c^2 because the two sides are equal. Then 100+100=200 and the square root of that is 10\sqrt{2}.
6)a^2+b^2=32^2
since a=b you can write the equation as, 2a^2=1024
a^2=1024/2 , which equals a=\sqrt{512}
and simplify it to 16

Answer:
Please check the attached graph.
From the graph, it is clear that option B is the correct option.
Step-by-step explanation:
Given the function
Determining the y-intercept
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
so
substituting x = 0 in the fuction
Apply rule:
Therefore, the point representing the y-intercept is:
- (0, 1.5)
Determining the x-intercept
We know that the value of the x-intercept can be determined by setting y = 0, and determining the corresponding value of x.
so
substituting y = 0 in the function
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
We know that can not be zero or negative for x ∈ R
Thus, NONE represents the x-intercept.
