What are the solutions for x when y is equal to 0 in the following quadraticfunction?
у = х^2 + 16х + 64
ОА) х = 0
ОВ) х = 8
OC) x = -8
OD) х = 0 or x = 8
OE) х = 0 or x = -8​
I did not mean to mark this under computer, I don't know how to fix it. ugh.

Answers

Answer:

OC) x = -8

Explanation:

Given Equation is:

y = x^(2) +16x+64

Putting y=0 will give us:

x^(2) +16x+64 = 0

The equation is a complete square

The formula is

a^(2)+2ab+b^(2)=(a+b)^(2)

So,

putting in the form of formula

(x)^(2)+ 2.x.8+(8)^(2)=0

(x+8)^(2) = 0

The square will be cancelled with square root

\sqrt{(x+8)^(2) } = 0

x+8 = 0

x = -8

There is only one root.

So, the solution for x wheny is equal to zero is x = -8 ..

The first computers stored their results on paper cards? True or false

Answers

false they used floppy disks witch stored its memory witch is made of plastic not papper
False, because in order to see whether they would work or not, and so they could view it later on future computers, they stored them on disks and most computers have actually been originated by some of the directions ON those disks,but if they would have used paper cards, then those cards might've been burned by competitors, or ripped or even thrown AWAY, which is WHY they chose to put the data on the disks. =)

LILLE VIC LUNCUL ANCI.A negative charge is moving across a room from south to north. A magnetic field runs from east to west. In what direction is the magnetic force
on the moving negative charge?
A toward the east
OB. toward the west
OC. toward the floor
D. toward the celling​

Answers

The correct option is C. toward the floor.

The magnetic force on the moving negative charge acts towards the floor.

Explanation:

The direction of the force applied on the moving charged particle placed in the magnetic field can be determined with the help of Fleming’s Left hand rule.

The current flows in the direction opposite to the direction of electron. If the electron moves from negative terminal to positive terminal, then the current will flow from positive terminal to negative terminal.

As given, the direction of electron- South to North

So the direction of current will be- North to South

Using Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.

Which problems result in a positive number? Choose all answers that are correct. A. –6 – (–8.1) B. C. 7.5 – (–1.4) D. –5.7 + 2.4

Answers

-6 - -8 = 2 so (A) is correct and 7.5 - -1.4= 8.9 so (C) is correct the rest result in negative numbers 
~Riley
You're answers would be A. and C. because of the if you subtract a negative and a negative, they will ALWAYS equal a positive, and a positive and positive will equal a positive, but a negative AND a positive will equal negative.
