1 hour = 60 minutes = (60 minutes)(60 seconds/minute)  = 3600 seconds
1 mi./57.1 sec. = (1 mi./ 57.1 sec.)(3600 sec./1 hour)
= (3600/57.1) mi./hr.

the answer is: 63.047 mi./hr.</span>

What is the rate of change of the function? On a coordinate plane, a line with negative slope goes through points (0, 1) and (1,
Blababa [14]

Answer:

-2

Step-by-step explanation:

slope: (y² - y¹) / (x² - x¹)

(-1 - 1) / (1 - 0) = -2 / 1 = -2

y = -2x + b

plug in an (x, y) value to find b

1 = -2(0) + b

1 = -2 + b

b = 3

y = -2x + 3

rate of change is -2

Fill in each blank so that the resulting statements are true.The vertices of The foci are located at ____.
stealth61 [152]

Given equation is

\frac{x^2}{9}-\frac{y^2}{16}=1

It can be written as follows.

\frac{x^2}{3^2}-\frac{y^2}{4^2}=1

Which is of the form

\frac{x^2}{a^2}-\frac{y^2}{b^2}=1

where a=3 and b=4.

We know that the coordinates of the vertices are (a,0) and (-a,0)

Substitute a=3, we get

The vertices are (3,0) and (-3,0).

We know that the coordinates of the foci are (c,0) and (-c,0)

c=\sqrt[]{a^2+b^2}

Substitute a=3 and b=4, we get

c=\sqrt[]{3^2+4^2}=\sqrt[]{9+16}=\sqrt[]{25}=5

Substitute c=5, we get

Hence the foci are (5,0) and (-5,0).

Infotron Inc makes electronic hockey and soccer games. Each hockey game requires 2​ labor-hours of assembly and 2​ labor-hours o
OlgaM077 [116]

Answer:

<u>Infotron should produce each day 13 hockey and 6 soccer games</u>

Step-by-step explanation:

x = Number of hockey games Infotron should produce

y = Number of soccer games Infotron should produce

Number of labor-hours for assembly = 2x + 3y

Number of labor-hours for testing = 2x + y

Now we can write our equations system, this way:

2x + 3y = 44

2x + y = 32

*********************

Expressing y in terms of x in the 2nd equation:

2x + y = 32

y = 32 - 2x

********************

Substituting y and solving for x in the 1st equation:

2x + 3y = 44

2x + 3 * ( 32 - 2x) = 44

2x + 96 - 6x = 44

-4x = 44 - 96

-4x = - 52

x = -52/-4

x = 13

*****************

Solving for y in the 2nd equation:

2x + y = 32

2 * 13 + y = 32

26 + y = 32

y = 32 - 26

y =<u> 6</u>

<u>Infotron should produce each day 13 hockey and 6 soccer games</u>
