Answer:

No point

Step-by-step explanation:

This is a trick question because if you break down the graphing equations to y=mx+b, you see that it is a linear graph, so it will have a straight line. For the first equations, y=x+3, you look at the original equations, y=mx+b. m=slope, b=x-intercept. Slope is rise/run (y/x) so the slope would be up one, over one (1/1=1). The x-intercept is 3 so its a straight line but it intercepts at 3. The next equation is the exact same thing, but the x-intercept is at 1. A straight line that intercepts at 1. So it is two parallel lines that never ever touch. So this is a trick question.

The unitary method is used to find the unit value of any quantity.

(a)The human heart pumps 300 quarts/hour.

(b) The human heart pumps 4.730 liters/minute.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

Reading on the label is 5quarts/min.

Since, 60 min = 1 hour

Use unitary method to get,

1 min = 1 / 60 hour.

Therefore, pumping of blood in quarts/hour = 5 / (1 / 60)

                                                                         = 5 × 60

                                                                         =  300

Since, 1 quart = 0.946 liter

The pumping of blood in liter/minute = 0.946 × 5

                                                               = 4.730.

Hence, the human heart pumps 300 quarts of blood per hour and 4.730 liter of blood per minute.

Answer:

The correct option is;

Increasing one fifth unit/sec

Step-by-step explanation:

The equation that gives the curve of the particle of the particle is y = 5·x² - 1

The rate of decrease of the y value dy/dt = 2 units per second

We have;

dy/dx = dy/dt × dt/dx

dy/dx = 10·x

dy/dt = 2 units/sec

dt/dx = (dy/dx)/(dy/dt)

dx/dt = dy/dt/(dy/dx) = 2 unit/sec/(10·x)

When x = 1

dx/dt = 2/(10·x) = 2 unit/sec/(10 × 1) = 1/5 unit/sec

dx/dt = 1/5 unit/sec

Therefore, x is increasing one fifth unit/sec.

Answer:

First Option {-2 , 0 , 2}

Step-by-step explanation:

A critical point occurs when the derivative is 0 or undefined.

The function in the question is undefined at x = 2 and at x = -2 because if we put x = 2 or x = -2 the denominator becomes 0 hence anything divided by 0 is undefined, and the derivative equals 0 at x = 0 so the critical points are

{-2 , 0 , 2}

Use the quotient rule to find the derivative of the function then equal it to zero

[tex]y=\frac{x^2-1}{x^2-4}\\\\\frac{dy}{dx}=\frac{(x^2-4)(2x)-(x^2-1)(2x)}{(x^2-4)^2}\\\\0=\frac{(x^2-4)(2x)-(x^2-1)(2x)}{(x^2-4)^2}\\\\0=2x^3-8x-2x^3+2x\\0=-6x\\x=0[/tex]

Answer:

The total flow in gallons is approximately 16.524 gallons

Step-by-step explanation:

The given diameter of the tank, D = 18 inches

The amount by which the water depth rose, Δh = 15 inches

The quantity being measured = The total flow = The change in volume of water in the tank

The change in the volume of the water in the tank, ΔV = (π × D²/4) × Δh

Substituting the known values, gives;

ΔV = (π × D²/4) × Δh = (π × (18 in.)²/4) × (15 in.) ≈ 3817.035 in.³

1 gallon = 231 in.³

ΔV ≈ 3817.035 in.³ = 3817.035 in.³ × 1 gallon/(231 in.³)  ≈ 16.524 gallons

The change in the volume of the water in the tank, ΔV in gallons = The total flow in gallons ≈ 16.524 gallons.

The given point 1/4  lie closer to 0& 1/2 than 1

A decimal number is a number that consists of a whole number and a fractional part separated by a point. For example – 3.5, 6.79, 78.32, etc.

Given here: Given the proper fraction as 1/4

To convert a fraction to a decimal, we'll just divide the numerator...by the denominator.

Thus 1/4=0.25

1/2=0.5

Now the difference between each of the given points is 1/2-1/4=0.25

And 1/4-0=0.25

Also 1-1/4=0.75

Thus the point 1/4 is equidistant from the points 0 and 1/2 but is 0.75 units away from 1

Hence, The given point 1/4  lie closer to 0& 1/2 than 1

Answer:

m=4/3

b=0

Step-by-step explanation:

m= is the slope, which is 4/3 and b is the y intercept, which is (0,0). The equation would be y=4/3x+0 but we do not have to include the 0 making it y=4/3x. The equation is proportional becuase it goes through the point (0,0) and it is linear as it is a linear line.

The graph of absolute value function f(x) and g(x) are:

On a coordinate plane, y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).

The correct answer is an option (B)

"A function of the form f(t) = |t| ."

"It is a set of points on the coordinate plane that follows given function."

For given question,

We have been given an absolute value function f(x) = |x|

and absolute value function g(x) = |-4(x - 7)|

The graph of f(x) = |x| is like a 'V', with its vertex at (0, 0).

Y = f (x) opens up and goes through (-4, 4), has a vertex at (0, 0), and goes through (4, 4)

Consider absolute value function, h(x) = |x - 7|

A function h(x) is the function f(x) is translated horizontally 7 units right.

The graph of h(x) = |x - 7| is like a 'V', with its vertex at (7, 0).

Now consider absolute value function g(x) = |-4(x - 7)|

A function g(x) is the function h(x) is compressed inside by factor 4.

So, the graph of y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4).

Therefore, the graph of absolute value function f(x) and g(x) are:

On a coordinate plane, y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).

Given:

The equation of ellipse is

[tex]\dfrac{(x+4)^2}{25}+\dfrac{(y-1)^2}{16}=1[/tex]

To find:

The length of the minor axis.

Solution:

The standard form of an ellipse is

[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex]      ...(i)

where, (h,k) is center, if a>b, then 2a is length of major axis and 2b is length of minor axis.

We have,

[tex]\dfrac{(x+4)^2}{25}+\dfrac{(y-1)^2}{16}=1[/tex]      ...(ii)

On comparing (i) and (ii), we get

[tex]b^2=16[/tex]

Taking square root on both sides.

[tex]b=\pm 4[/tex]

Consider only positive value of b because length cannot be negative.

[tex]b=4[/tex]

Now,

Length of minor axis = [tex]2b[/tex]

                                  = [tex]2(4)[/tex]

                                  = [tex]8[/tex]

So, the length of minor axis is 8 units.

Therefore, the correct option is B.
