Answer:

(a) 95% of 80 is basically you move the percent sign 2 places to the left which makes it 0.95 then just multiply 0.95x80

(b) the first step is to divide 18 by 40 to get the answer in decimal form:

18 / 40 = 0.4500

then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:

0.4500 * 100 = 45.00%

we can prove that the answer is correct by taking 45.00 percent of 40 to get 18:

(40 x 45.00)/100 = 18

note that our calculator rounds the answers up to two decimals if necessary. Once again, the answer is as follows:

45.00%

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.

Answer:

type 2 in the first box,

13/4 in the second box, and

-9/8 in the third one

Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:

x_{vertex}= -b/2a

Which in our case is: -13/4

and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:

f(-13/4)= -9/8

Then your expression for this quadratic should be:

f(x)=2\,(x+\frac{13}{4} )^2+(-\frac{9}{8})

Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one
