What is the factored form of the polynomial? (z2 10z + 25) A. (z − 5)(z − 5)
B. (z + 5)(z + 5)
C. (z − 2)(z + 5)
D. (z + 2)(z − 5)

Answers

Answer 1
Answer:

Solution-

As the question is not complete so contemplating all the possible scenarios,

1st - z² + 10z + 25

2nd - z² - 10z + 25


For,

z^2 + 10z + 25 = (z)^2+2.z.5+(5)^2 = (z+5)^2=(z+5)(z+5)


And for,

z^2 - 10z + 25 = (z)^2-2.z.5+(5)^2 = (z-5)^2=(z-5)(z-5)


So, the factored form of the polynomials are,

(z+5)(z+5) \ and \ (z-5)(z-5)
Answer 2
Answer:

The factors of the equation  z² - 10z + 25 are (z − 5)(z − 5).

Given Equation;

z² - 10z + 25

What are the factors?

Splitting the middle term Using formula Using Quadratic formula Using algebraic identities.

The factors of the equation are;

z² - 10z + 25

z² -5z -5z  + 25

z(z − 5) - 5(z − 5)

(z − 5)(z − 5)

Hence, the factors of the equation z² - 10z + 25 are (z − 5)(z − 5).

1. What is the length of the segment joining the points at (-1,6) and (-5,3) 2. What is the length of the segment joining the points at (-4, 1) and (3,7)

Answers

QUESTION 1

We want to find the length of the segment joining the points at (-1,6) and (-5,3).



We use the distance formula which is given by the formula,

d=√((x_2-x_1)^2+(y_2-y_1)^2)


d=√(( - 5 - - 1)^2+(3 - 6))^2)


d=√(( - 5 + 1)^2+(3 - 6)^2)



d=√(( - 4)^2+( - 3)^2)


d=√(16+9)


d=√(25)

d = 5 \: units


QUESTION 2

We want to find the length of the segment joining at (-4,1) and (3,7).




We use the distance formula to get,


d = \sqrt{(3 - - 4)^(2) + {(7 - 1)}^(2) }

d = \sqrt{(3 + 4)^(2) + {(7 - 1)}^(2) }




d = \sqrt{7^(2) + {6}^(2) }


d = √(49+ 36 ) .


d = √(85 ) \: units

Can someone simplify this please!! (3.1)⋅(10.75−3.55)

Answers

Answer:

Simplification of the expression (3.1)⋅(10.75−3.55) is:

22.32

               

Step-by-step explanation:

We have to simplify:

(3.1)⋅(10.75−3.55)

(3.1)⋅(10.75−3.55)=(3.1)·(7.2)

                          =22.32

Hence, on simplifying the expression (3.1)⋅(10.75−3.55) , we get:

22.32

                     

(3.1)*(10.75-3.55)=
(3.1)*(7.20)
=22.32 :)

autumn used 0.675 of the battery life on her mp3 player. her brother borrowed it to play a game and used 0.2 of the total battery life. of her mp3 player shows the battery life that remains as a percentage, what does it showed after her brother is finished?

Answers

She starts out with the battery 100% full.
0.675 as a fraction is 67.5%
Subtract 67.5% from the initial amount.
100% - 67.5% = 32.5%
0.2 as a fraction is 20%
Subtract 20% from the amount left:
32.5% - 20% = 12.5%.She has 12.5% left.
