consider a quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1). determine the most accurate type of quadrilateral from the
Burka [1]

Answer:

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

Step-by-step explanation:

Considering the quadrilateral with vertices

  • d(0,0)
  • i(5,5)
  • n(8,4)
  • g(7,1)

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

From the figure a, it is clear that the quadrilateral has

  • Two pairs of sides
  • Each pair having two equal-length sides which are adjacent
  • The angles being equal where the two pairs meet
  • Diagonals as shown in dashed lines cross at right angles,  and one of the diagonals does bisect the other - cuts equally in half

Please check the attached figure a.

Factor 9b^2 - 4.<br><br> (3b + 1)(3b - 4)<br> (3b + 2)(3b - 2)<br> (3b - 2)(3b - 2)
maria [59]

The answer should be (3b + 2)(3b - 2) since if you multiply those two, you will get back to original equation.

Hope this helps!

110 freshmen participated in sports or clubs or both. 55 are involved in sports and 68 are involved in clubs. How many students
Varvara68 [4.7K]

Answer: 42

Step-by-step explanation:

Let A represents the number of freshmen participated in sports and B represents the number of  freshmen participated in clubs.

Then , we have given that

n(A)=55\\\\n(B)=68\\\\n(A\cup B)=110

Using formula

n(A\cup B)=n(A)+n(B)-n(A\cap B)

We have,

110=55+68-n(A\cap B)\\\\\Rightarrow\ n(A\cap B)=123-110=13

Now, the number of students are involved in just sports is given by :-

n(A)-n(A\cap B)=55-13=42

Hence, 42 students are involved in just sports.
