Answer:

4.5 cm.  

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

\text{Circumference of a circle}=2\pi r

Upon substituting the measure of circumference in above formula we will get,

28.3=2\pi r  

r=\frac{28.3}{2\pi}

r=4.504084889500638\approx 4.5

Therefore, the radius of circle O is 4.5 cm.

Use the elimination method to solve the system of equations. Choose the correct ordered pair. 
kiruha [24]
5x+3y=58
5x-3y=22
(3y gets cancelled bc 3y-3y=0,  then add 5x with 5x, so you're left with)
10x=80, (divide both sides by 10)
x=8
Now we look for y. So choose one formula from the two (let's say 5x + 3y=58)
Substitute x for 8 so it will look like---- 5(8)+3y=58
Multiply 5*8--- so you get --  40+3y=58
Subtract 40 from both sides and you're left with 3y=18
divide both sides by 3
you get y=6
In conclusion, x=8 and y=6 hence, (8,6)

In 5 he will use, 5/8 *5 = 25/8 in 5 weeks 
This can be simplified too:
3.125 tanks of gas

The answer is, 25/8 tanks of gas or 3.125 tanks of gas

Prove the following relations: <br>1) (1 - cos²A) (1 + tan²A) = tan²A​
liberstina [14]

Step-by-step explanation:

(1 - cos²A) (1 + tan²A) = tan²A

(sin²A)(sec²A) = tan²A

(sin²A)(1/cos²A) = tan²A

(sin²A)/(cos²A) = tan²A

tan²A = tan²A → <u>Proved</u>
