a machine can fill 650 bottles in 25 minutes. What is the unit rate at which the machine fills the bottles?

1 answer:

8 0

$unit\ rate=\frac{amount\ of\ bottle}{time}\\\\
unit\ rate=\frac{650}{25}=26\frac{bottle}{min}\\\\Unit\ rate\ is\ 26\ bottle\ per\ minute.$

Show how to solve 8x^2+14x+5=0 by completing the square.

Phoenix [80]

8 x² + 14 x + 5 = 0
2 ( 4 x² + 7 x ) = - 5
2 ( 4 x² + 7 x + 49/16 - 49/16 ) = -5
2 ( 4 x² + 7 x + 49/16 ) - 98/16 = - 5
2 ( 2 x + 7/4 )² = - 5 + 98/16
2 ( 2 x + 7/4 )² = -80/16 + 98/16
2 ( 2 x + 7/4 )² = 18/16 = 9/8 / : 2
( 2 x + 7/4 )² = 9/16 / √
2 x + 7/4 = 3/4
2 x = 3/4 - 7/4 = -1
x = - 1
and 2 x + 7/4 = -3/4
2 x = -7/4 - 3/4 = - 10/4= -5/2
x = - 5 / 4

If the coefficient a in the general quadratic equation is equal to 9, what is the focal length for the

lutik1710 [3]

Answer:

Step-by-step explanation:

Let the equation of a parabola be

$y^{2}$ = 4ax.

Then , focal length of the parabola is a.

As , (0,0) is the vertex and its focus is (a,0)

Thus, focal length comes out to be a.

Here,

a is given as 9 units .

Thus focal length of the parabola, d, equals to 9 units

Keep in mind that you can gather only like terms. Two terms can be summed/subtracted if they involve the same powers of the same variables.

So, going point by point:

We can subtract the terms, because they both involve the variable $b$ , and we have $3b-7b = (3-7)b = -4b$
We can sum the terms, because they all involve the variable $a$ , and we have $a+a-5a = (1+1-5)a = -3a$
We can't sum this terms: 3 is a pure number, while 3r involves the variable r.
We can only sum the two terms: we have $7t-8t-8 = (7-8)t-8 = -t-8$
We can't sum this terms: -20 is a pure number, while -15p involves the variable p.
We can sum the terms, because they all involve the variable $g$ , and we have $-g-g-g = (-1-1-1)g = -3g$
