NEED HELP! WILL MARK BRAINLIEST!

Mathematics
1 answer:
MaRussiya [10]3 years ago
5 0

Answer:

67.5 square units

Step-by-step explanation:

Add points A, B, C, D, E and F. Note that

A_{ABCD}=A_{AMN}+A_{MBL}+A_{CKL}+A_{JKE}+A_{EDFJ}+A_{NJF}+A_{JKLMN}

Find these area:

A_{ABCD}=AB\cdot BC=10\cdot 12=120\ un^2.\\ \\A_{AMN}=\dfrac{1}{2}AN\cdot AM=\dfrac{1}{2}\cdot 3\cdot 6=9\ un^2.\\ \\A_{MBL}=\dfrac{1}{2}MB\cdot BL=\dfrac{1}{2}\cdot 4\cdot 8=16\ un^2.\\ \\A_{CKL}=\dfrac{1}{2}CK\cdot CL=\dfrac{1}{2}\cdot 3\cdot 4=6\ un^2.\\ \\A_{JKE}=\dfrac{1}{2}EK\cdot EJ=\dfrac{1}{2}\cdot 3\cdot 1=1.5\ un^2.\\ \\A_{EDFJ}=ED\cdot EJ=4\cdot 1=4\ un^2.\\ \\A_{FJN}=\dfrac{1}{2}FN\cdot FJ=\dfrac{1}{2}\cdot 8\cdot 4=16\ un^2.

So,

120=9+16+6+1.5+4+16+A_{JKLMN}\\ \\A_{JKLMN}=120-9-16-6-1.5-4-16=67.5\ un^2.

A baseball is thrown at an angle of 30° with respect to the ground and it reaches the ground in 2 seconds. What is its initial v
NeTakaya

Answer:

The answer to your question is vo = 19.62 m/s

Step-by-step explanation:

Data

angle = α = 30°

time = t = 2 s

vo = ?

g = 9.81 m/s²

Formula

                  t = \frac{2vosin\alpha}{g}

Solve for vo

             vo = \frac{tg}{2sin\alpha}

Substitution

            vo = \frac{(2)((9.81)}{2sin 30}

Simplification

           vo = \frac{19.62}{2(0.5)}

           vo = \frac{19.62}{1}

Result

            vo = 19.62 m/s

Describe the transformation done to y = 1/x to get y = 1/4x -12?
BabaBlast [244]
The transformation is done to y=1/x to get y=1/4x-12. We defined a turning point in the equation which will indicate the point in the graph.

We changed the form from y=x to y=x+c. In this case, we use 1/2 for the and constant C value which is -12.
