Counterexample: 2/10 and 3/8

The product of the two denominators is 10*8 = 80

The LCD is found by mulitplying the non common prime factors and the common prime factors raised to the higher power:

10 = 2*5

8 = 2^3

LCD = (2^3)*5 = 8 * 40.

This counterexample shows the statement is false.

Andy completes the square for the function y = x^2 + 6x -8 Which of the following functions reveals the vertex of the parabola?

LiRa [457]

Answer:

B. y = (x + 3)^2 - 17

Step-by-step explanation:

When Andy completes the square, he adds and subtracts the square of half the x-coefficient. That is, he adds and subtracts (6/2)² = 9:

... y = x² +6x +9 -8 -9

... y = (x² +6x +9) -17

... y = (x +3)² -17 . . . . . . . . matches selection B

Answer:

The volume of tennis ball = 38.808 $cm^{3}$ .

Volume of golf ball = 33.523 $cm^{3}$ .

Step-by-step explanation:

Given: The radius of the tennis ball is 2.1cm and the radius of thr golf ball is 2.0cm. the formula is V=4πr(to the 3rd power) /3 .

To find: Volume of tennis ball and golf ball .

Formula used: Volume = $\frac{4 π r^{3} }{3}$ .

pi(π) = $\frac{22}{7}$ .

Explanation : We are given that

Radius of the tennis ball = 2.1 cm

radius of the golf ball =2.0 cm.

We need to find the volume of each ball

So , plugging the given values of radius in above formula

Volume of the tennis = $\frac{4*22(2.1)^{3} }{3*7}$

On simplification we get, volume of tennis ball = 38.808 $cm^{3}$

Volume of the golf ball= $\frac{4*22(2.0)^{3} }{3*7}$

On simplification we get, volume of golf ball = 33.523 $cm^{3}$

Therefore , The volume of tennis ball = 38.808 $cm^{3}$ .

Volume of golf ball = 33.523 $cm^{3}$ .
