What is the positive solution to the equation 64x2 + 12x = 1.

Inga [223]

Answer:

1/16

Step-by-step explanation:

Here: 64x^2+12x = 1

Then, 64x^2 +12x -1=0

The delta = 12^2 - 4*64*(-1)= 400 = 20^2

These two solutions are:

(-12+20)/(2*64)= 8/(2*8*8)= 1/16

(-12-20)/(2*64) but this is negatif.

1/16 is the positif solution.

Hope that useful for you.

great rapids white water rafting company rents for $125 per hour. Explain why the point (0,0) and (1,125) are on the graph of th

Artist 52 [7]

(0,0) represents the very beginning of the rental period: 0 time has elapsed, and thus there is no charge.

(1,125) represents this situation 1 hour after the rental has begun, and shows that the amount due at that point for the rental is

$125.

Answer:

Soup B

Step-by-step explanation:

Given :

Soup A:

Sodium(mg) 720

Ounces 6 1

Soup B :

Sodium(mg) 600

Ounces 4 1

To Obtian the amount of sodium per ounce in each of soup A and B

Soup A :

Sodium per ounce = 720 mg / 61 = 11.803 mg / ounce

Soup B:

Sodium per ounce = 600 mg / 41 = 14.634mg / ounce

Hence. SOUP B contains more soudiun per ounce

What is the slope of a line parallel to the line with this equation:

Nutka1998 [239]

The slope of two parallel lines are equal.

Let us find slope of given equation.

The general slope intercept form is given by :

$y=mx+c$

where m is slope

our equation is :

$5x-15y=30$

Now we have to convert our equation into slope intercept form.

let us try to isolate y on the left side.

taking 5x to the right side we have ,

$-15y=-5x+30$

dividing both sides by -15,

$y=\frac{x}{3} -2$

coefficient of x is slope,

so slope is 1/3

slope of line parallel to it is also same that is 1/3 .

Correct option is D.

Two supplementary angles are in the ratio 3 1 : 5 find both angles

Zielflug [23.3K]

The two angles are 155 degrees and 25 degrees

<h3><u>Solution:</u></h3>

Given that two supplementary angles are in ratio 31 : 5

Let the first angle be 31a

Let the second angle be 5a

Two Angles are Supplementary when they add up to 180 degrees.

Therefore,

first angle + second angle = 180 degrees

$31a + 5a = 180\\\\36a = 180\\\\a = \frac{180}{36}\\\\a = 5$

<em><u>Therefore the angles are:</u></em>

first angle = 31a = 31(5) = 155 degrees

second angle = 5a = 5(5) = 25 degrees

Thus the two angles are 155 degrees and 25 degrees
