Identify the roots of the function g(x) = x^2 - 8x + 16

Answers

Answer 1

Answer:
A function doesn't have roots until you give it a numerical value.
Then, the roots are the values of the variable that give the function
that value.

For example, if you said that g(x) = 0,
then the roots would both be x = 4 .

But if you said that g(x)=16, then
the roots would be x=0 and x=8 .

Answer 2

Answer: A function is not this but for example g times x is

A sprinkler mounted on the ground sends out a jet of water at a 30o angle to the horizontal. The water leaves the nozzle at a speed of 12 m/s. (a) How far does the water travel before it hits the ground?

Answers

Answer:

12.7m

Step-by-step explanation:

The equation for motion to be used to find how far the water travels is

xf = xi + Vix(t) + 1/2axt^2

xf = 0 + ViCos α(t) + 0

xf = ViCosα(t)

xf = 12 Cos 30°(t)

xf = (6√3)t

To find the total times we will use the vertical displacement equation

yf = yi + Viy(t) + 1/2ayt^2

0 = 0 + ViSinα(t) + (1/2 * (-9.8)t^2)

0 = 12Sin30°(t) - 4.9t^2

4.9t^2 = 12Sin30°(t)

4.9t^2 = 6t

Divide through by t

4.9t = 6

t = 6/4.9

t = 1.22secs

Put t = 1.22 into (6√3)t

xf = 6√3 * 1.22

xf = 12.7m

How many times greater is the value of 3 in 300 than the value of the 3 in 30

Answers

The 10 times greater is the value of 3 in 300 than the value of 3 in 30 after using the concept of fraction.

What is a fraction?

Fraction number consists of two parts, one is the top of the fractionnumber which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

How many times greater is the value of 3 in 300 than the value of the 3 in 30

Let x be the number of times the value of 3 in 300.

The equation can be framed:

3x = 300

x = 300/3

x = 100

Let y be the number of times the value of the 3 in 30:

The equation can be framed:

3y = 30

y = 30/3

y = 10

Take the fraction:

x/y = 100/10

x/y = 10

x = 10y

Thus, the 10 times greater is the value of 3 in 300 than the value of 3 in 30 after using the concept of fraction.

Well it sounds like you mean smaller, not greater. 3/300 = 1/100 while 3/30 = 1/10. So 3 out of 300 is 10 times SMALLER than 3 out of 30.

Step-by-step explanation:

how do you solve the system of elimination method.

x-6y=-30

-2x-5y=-25

Answers

x-6y=-30...equatn 1
-2x-5y=-25....equatn 2
multiply eqn 1 and 2 with 5 and 6 respectively
5x-30y=-150
-12x-30y=-150
subtract to eliminate y
17x=0
x=0
substitute x=0 into any of the equations
0-6y=-30
-6y=-30
y=-30/-6
y=5
x=0;y=5

x - 6y = -30 / * 2
-2x - 5y = -25

2x - 12y = -60
-2x - 5y = -25
--------------------
+
2x - 2x - 12y - 5y = -60 - 25
-17y = -85 / : (-17)
y = 85/17
y = 5

y = 5
x - 6y = -30

y = 5
x - 6 * 5 = -30

y = 5
x - 30 = -30

y = 5
x = 30 - 30

y = 5
x = 0

answer:
x = 0
y = 5
