Answer:

Area of the sector = 57.26295cm²

Step-by-step explanation:

Radius of the circle=9cm

π= 3.142

Angle at B= 81° ( opposite angle of a quadrilateral)

Area of the sector = πr² * 81/360

Area of the sector = 3.142 * 9*9 * 0.225

Area of the sector= 3.142*81*0.225

Area of the sector = 57.26295cm²

alekssr [168]

Answer:

<h2>0.00390625 / 4^{-4} </h2>

Step-by-step explanation:

so you are saying do:

4^{2} /4^{6} which is 16 /4096

16/4096=0.00390625

<u>another way you can do this is</u>

4^{2} /4^{6}

just subtract the powers

2-6=-4

so the answer is 4^{-4}

Is this thesis OK for my schizophrenia essay? Schizophrenia is a severe mental illness that deeply affects the patient's daily l
sattari [20]
I don't know how many paragraphs your professor needs you to develop, but if your essay consists on just 3 paragraphs (introduction, body and conclusion) your thesis is OK.
Now, if your essay needs to have, lets say 4 or 5 paragraphs (introduction, body 1, body 2, body 3, and conclusion) I'd recommend you to add two more details to your essay. For example,

Schizophrenia is a severe mental illness that deeply affects not only the patient's daily life, but also his family and friends.

paragraph 1 is to develop how schizophrenia affects the patient daily life only. Paragraph 2 is to develop how schizophrenia affects the patient's family and paragraph 3 to develop how it affects his or her family.

Don't forget to put examples, professors love when you put examples.
Good luck, and if you need help, you can ask me.
