F (a)=2a^2-16a+32
For which 'a' is this equation 0?

Answers

Answer 1
Answer: if xy=0 assume that at leas 1 is zero
set it to zero

0=2a^2-16a+32
undistribute 2
0=2(a^2-8a+16)
2*0=0 so assume
a^2-8a+16=0
factor
(a-4)(a-4)=0
set to zero
a-4=0
a=4


when a=4, equation equals zero

so the qustion is which of these shos the commutative property
the commutative property of multiplication is
note:ab=a times b=a(b)

so a(bc)=(ab)c

first choice: 4.1 times (6.2 times 5.0)=(4.1 times 6.2) times 5.0
this is obviously the right answer A is the answer

B
2.7 times 1=2.7 this is the identity property of multiplicaiton, anything times 1= same thing


C 7.2 times 0=0 this is the 0 property of multiplication

D. 8.5 times 0.4=0.4 times 8.5
this is the equality property

the answer is A

A fish tank is a cube. Its side length is 4 1/2 feet. The volume of water needed to completely fill the fish tank is ___ cubic feet.

Answers

The equation for the volume of a cube is V=s^3, where V is volume and s is side length.  Plug in and solve:

V=4.5^3

V=4.5*4.5*4.5

V=91.125ft^3

LC)Variable c is 9 more than variable w. Variable c is also 3 less than variable w. Which pair of equations best models the relationship between c and w? (5 points) c = w – 9
c = 4w + 3
c = w + 9
c = w – 3
w = c + 9
w = c – 3
w = c – 9
w = 4c + 3

Answers

c=w+9 and c=w-3

w=c-9 and w=c+3

These pairs of equations are best relationship models between c and w.

How to find pair of best relationship model for c and w?

We have given,

Variable c is 9 more than variable w which can be written as

c=w+9

It can also be written as :w=c-9

It is also given that,Variable c is also 3 less than variable w, which can be written as:

c=w-3

It can also be written as: w=c+3

This way our pair of relationship between c and w are:

c=w+9 and c=w-3

w=c-9 and w=c+3
