10.2 inches

Step-by-step explanation:

The diameter of the base ball is initially 20 inches.

Reducing 20 inches by 20% will be

(100-20)/100 *20

80/100*20=16 inches

Reducing 16 inches by 20% to will be;

80/100*16=1.6*8=12.8

Reducing 12.8 inches by 20 % will give

80/100* 12.8=10.24 inches

Nearest tenth the answer will be 10.2 inches

Hey can anyone pls answer these math problems!!
Zepler [3.9K]

Answer:

1={5 and 3} 2={0} 3={0.209 and 4.791} 4={-3 and 4} 5={1 and 9} 6={-4.303 and -0.697}

Step-by-step explanation:

Your probably confused on what a, b, and c means.

The problems are written like this.

ax^2+bx+c=0

That formula finds the zeros.

For example 1:

x^2-8x+15=0\\ax^2-bx-c\\a=1\\b=-8\\c=15

Then use the formula

x=\frac{-b+-\sqrt{b^2-4ac} }{2a} \\\\x=\frac{-(-8)+-\sqrt{-8^2-4(1)(15)} }{2} \\x=\frac{8+-\sqrt{64-60} }{2} \\\\x=\frac{8+-2}{2}\\

If plus then 5, if minus then 3

CHECK:

x^2-8x+15=0\\5^2-8(5)+15=0\\25-40+15=0\\0=0\\3^2-8(3)+15=0\\9-24+15=0\\0=0

Hope this helps you understand how to do this by yourself.  Now to do the rest ;-;

If P= (-6,4) find Ry= -x (P)
julsineya [31]

The value of Ry= -x (P) is P' = (4, 6)

<h3>How to determine the transformation?</h3>

The point is given as:

P = (-6, 4)

The transformation Ry= -x (P) means tha:

(x, y) = (y, -x)

So, we have:

P' = (4, 6)

Hence, the value of Ry= -x (P) is P' = (4, 6)
