Answer:
840cm²
Step-by-step explanation:
The two small triangle areas:
b × h / 2 = 12 × 5 = 60 / 2 = 30cm²
So two triangles would be 60cm²
Now, for the top rectangle:
b × h = 26 × 12 = 312cm²
The middle rectangle:
b × h = 26 × 13 = 338cm²
And the bottom last triangle:
b × h = 26 × 5 = 130cm².
Now to add them all: 60 + 312 + 338 + 130 = 840cm²
I advice you to just check to make sure the calculations were right! Good luck with the rest of your finals :)
Answer:
x² = y
Step-by-step explanation:
x² = y fit one input to one output property of function
Answer:
a) The study suggests a negative correlation because the study shows that as time spent on social networking websites Increases, grade point average tends to decrease.
b) While it is possible that there is a cause and effect relationship, it is not necessarily the case.
Step-by-step explanation:
Since the study submitted that, students who rarely never used social networking websites had higher grade point averages than students who use social networking websites. It implies a negative relationship. Thus, the option given above is the correct answer.
Similarly, the study might imply some cause and effect relationship but it is not necessarily to be the case. <em>That is, low grade point could result into more time with social networking website. </em><em>This is not necessary to be TRUE!</em>
Answer:
arg (w)=π/4 and |w|=√2
Step-by-step explanation:
If z= x+iy is a complex number, then |z| is given by √ ( x²+y² ).
And the argument (z) is given by Ф = tan⁻¹ ( y/x ) where -π < x < π.
Now, in our case w= 1+i i.e. x=1 and y=1.
Therefore, arg (w) = tan⁻¹ (1/1) = π/4 and |w|=√ ( 1²+1² ) = √2 (Answer)
