Answer:

  170 mph

Step-by-step explanation:

The speed of the airplane can be represented by s. The travel time will be ...

  time = distance/speed

  925/(s +15) = 775/(s -15)

  925(s -15) = 775(s +15)

  150s = 25500 . . . . . . . . . add 13875-775s

  s = 170

The rate of the plane in still air is 170 mph.

Answer:

x = 2

Step-by-step explanation:

First translate the image into an equation using the key. Once you do that, your equation should look like this:

(x + x + x) + (-1 + -1 + -1 + -1 + -1) = (-x + -x) + (1 + 1 + 1 + 1 + 1)

________________________________

3x - 5 = -2x + 5

(given)

________________________________

3x - 5 = -2x + 5

+5. +5

(addition property of equality)

*cancel out -5 on the left hand side, and isolate it from x by adding +5 on each side*

__________________________

3x = -2x + 10

+2x +2x

(addition property of equality)

*cancel out the negative 2x, and isolate it from the constant term on the right hand side by adding 2x on both sides*

________________________________

5x = 10

÷5. ÷5

(division property of equality)

*divide by 5(GCF) on both sides to isolate

x by itself*

________________________________

x = 2

________________________________

If you want to test this solution, substitute this back into the equation.

x = 2 → 3x - 5 = -2x + 5. 3(2) - 5 = -2(2) + 5 = 6 - 5 = -4 + 5 = 1 = 1

Answer:

c. This is a two-tailed test.

Step-by-step explanation:

When the rejection region is divided between the two tails of the sampling distribution of the test statistic the test is referred to as two tailed or two sided test. In this case the alternative is set up as

Ha : u≠ 1.7

meaning that values both larger and smaller than u are to be included.

When the alternative hypothesis has the "not equal to sign"  it gives the two tailed test.

Answer:

1. Its about 14.90697674418605. I’m not sure if u want it rounded up if u want it rounded up to the nearest whole it would be 15 if I wanted it rounded up to the nearest tenth then it would be 14.9

2. It’s about 173.4814814814815. I wasn’t sure if I wanted this one rounded up too. Rounded up to the nearest whole it would be 173 and rounded up to the nearest tenth it would be 173.5

3. It’s about 100.859375. I wasn’t sure on this one too. Rounded up to the nearest whole would be 101 and rounded up to the nearest tenth it would be 100.9

The value of 70 fluid ounces in liters would be, 2.065 liters

Used the concept of measurement unit that states that,

A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.

To change 70 fluid ounces in liters.

Since we know that,

1 fluid ounce = 0.0295 liters

Hence, change the units of 70 fluid ounces in liters,

1 fluid ounce = 0.0295 liters

70 fluid ounce = 70 × 0.0295 liters

= 2.065 liters

So, we get;

70 fluid ounce = 2.065 liters

Answer:

A point on the ellipsoid is (-4,2,2) or (4,-2,-2)

Step-by-step explanation:

Given equation of ellipsoid f(x,y,z) :[tex]x^2+y^2+4z^2=36[/tex]

Parametric equations:

x=-4t-1

y=2t+1

z=8t+3

Finding the gradient of function

[tex]\nabla f(x,y,z)=<\frac{\partial{f}}{\partial{x}},\frac{\partial{f}}{\partial{y}},\frac{\partial{f}}{\partial{z}}>\\\nabla f(x,y,z)=<2x,-2y,8x>[/tex]

So, The directions vectors=(-4,2,8)

Now the line is perpendicular to plane when direction vector is parallel to the normal vector of line

[tex]\nablaf(x,y,z)=(2x,2y,8z)=\lambda(-4,2,8)[/tex]

So, [tex]2x=-4\lambda[/tex]

[tex]\Rightarrow x=-2\lambda[/tex]

[tex]2y=2\lambda\\\Rightarrow y=\lambda\\8z=8\lambda\\\Rightarrow z=\lambda[/tex]

Substitute the value of x , y and z in the ellipsoid equation

[tex](2\lambda)^2+(\lambda)^2+4(\lambda)^2=36\\9(\lambda)^2=36\\\lambda^2=4\\\lambda=\pm 2[/tex]

With [tex]\lambda = 2[/tex]

x=-2(2)=-4

y=2

z=2

With[tex]\lambda =- 2[/tex]

x=-2(-2)=4

y=-2

z=-2

Hence a point on the ellipsoid is (-4,2,2) or (4,-2,-2)

Answer:

  no, it makes the equation false

Step-by-step explanation:

A "solution" is a value of x that makes the equation true. When we use 4 in place of x here, we get ...

  5 + 4 = 10

  9 = 10 . . . . . . . a false statement

The value x=4 does not make the equation true, so it is not a solution.

Answer:

Correct

Step-by-step explanation:

The supplementary angle to any of the interior angles of a triangle is called an exterior angle, they are supplementary because they form a 180º angle when you extend a straight line from the adjacent side of the angle and any straight angle is a 180º angle, so supplementary angles added up would make 180º.

Answer:

x = .28

y = 0

Step-by-step explanation:

Voume of disk = pi *r^2 = pi * e^-3x deltax

x = integal 0 to 1 of x * delta*pi*e^-3x deltax / mass = (delta*pi) integal 0 to 1 of x * e^-3x deltax/mass = (delta*pi)0.08898/mass

mass = sigma *(volume)=delta(pi/3*(1-e^-3)) =delta(.995)

x = (delta*pi)0.08898/delta(.995) = .28

by symmetry y=0

A solid is formed by rotating the region bounded by the curve y = e^-3x/2 and the x axis between x=0 and x=1 around the x axis.  Then value of x is 0.28 and y is 0.

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.

The volume of disk is given by formula πr²

Volume of disk =  πr²= π × e⁻³ˣ Δx

[tex]x=\int\limits^0_1 {x} \, \pi e^{-3x} dx[/tex]

= (delta.π) integal 0 to 1 of x × e⁻³ˣ delta x/mass

= (delta. π) 0.08898/mass

mass = sigma ×(volume)=delta( π/3*(1-e⁻³)) =delta(0.995)

x = (delta*π)0.08898/delta(0.995) = 0.28

x=0.28

and by symmetry y=0

Hence the value of x is 0.28 and value of y is 0.
