I need help ASAP!!! Please explain how to solve the problem I am stuck

Kazeer [188]

Answer:

( x - 11 )^2 + ( y - 5 )^2 = 4^2

Step-by-step explanation:

The general form of equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2.

h and k are the co-ordinates of the center of circle and r is the radius

We have,

r=4

(h,k)=(11,5)

( x - h )^2 + ( y - k )^2 = r^2

or, ( x - 11 )^2 + ( y - 5 )^2 = 4^2

If you simplify,

x^2-22x+121+y^2-10y+25=16

or, x^2+y^2-22x-10y+146-16=0

or,x^2+y^2-22x-10y+130=0

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed

shusha [124]

Answer:

We inject 60.9628 milliliters of dosage.

Step-by-step explanation:

Given : You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hosts weight as 168 pounds.

To find : How many milliliters (= cc) are you to inject?

Solution :

We know that,

1 pound = 0.453592 kg,

Patient's weight = 168 pounds

Patient's weight in kg = $168\times 0.453592=76.203456$ kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight = $0.4 \times 76.2035\ mg = 30.4814\ mg$

We know, 1 micro gram = 0.001 mg

Concentration of drug is given by,

$500\ \text{micro grams/ml}= 500\times 0.001\ \text{mg/ml} = 0.5\ \text{mg/ml}$

Now we are supposed to find milliliters inject,

So, milliliters of dosage required to inject is

$d= \frac{30.4814}{0.5} = 60.9628$

Therefore, We inject 60.9628 milliliters of dosage.

PLEASE I NEED HELP

Shaded area = Quarter circle area - Equilateral triangle

$s \: a = \pi \times ( {radius})^{2} - \frac{1}{2} \times \: base \times \: height \\$

$s \: a = \pi \times {7}^{2} - \frac{1}{2} \times 7 \times 7 \\$

$s \: a = 49\pi - \frac{49}{2} \\$

$s \: a = 49 \times 3.14 - 24.5$

$s \: a = 153.86 \: - 24.5$

$shaded \: \: area = 129.36$

There you go...

Have a great day ❤

Solve this equation -98=7(n-7)

Sergeeva-Olga [200]

-98=7(n-7)

-98=7n-49

7n=-98+49

7n=-49

Therefore n=-7, as 7(-7)=-49.
