Answer:

1 hr at the speed of 50 mph

Step-by-step explanation:

If you went 50 mph it would be 1 hour. 100mph = 30min.

The time it will take to cover a given a given distance of 50 miles, assuming a speed of 20 miles per hour is 2 hours 30 minutes

Given Data

Distance = 50 miles

We Need another parameter speed, this will help us determine the exact time it would take to travel given the distance

Let us assume a speed of 20 miles per hour

We know that the expression relating speed, distance and time is given as

Speed = Distance/Time

Substituting we have

20 = 50/t

solving for t we have

t = 50/20

t = 2.5 hours

This is the same as 2 hours 30 minutes

Answer:

The number might be 2and 18 if we find ratio of 2 and 18 it comes 1:9

Answer:

1:8

Step-by-step explanation:

well, you're starting with the ratio 2:16, if you divide that by 2 (simplest form) you get 1:8

You can use the Pythagoras theorem to get the value of x.

The value of x is given by

Option C: x = 6.2

The Pythagoras theorem:

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

Refer to the figure attached below.

The triangle BAD is right angled triangle (one angle is 90 degrees).

The length of CD is 13 - x units.

Thus, we have:

[tex]|AD|^2 + |DB|^2= |AB|^2\\\\Length(AD)= \sqrt{169-81} = \sqrt{88} = 2\sqrt{22}[/tex]

For triangle ACD, we have:

[tex]|AC|^2 +|CD|^2 = |AD|^2\\|AC| = \sqrt{(2\sqrt{22})^2 - (13-x)^2} = \sqrt{-81 -x^2 - 26x}\\[/tex]

For triangle ACB, we have;

[tex]|AB|^2 = |AC|^2 + |CB|^2\\81 = (-81-x^2 +26x) + x^2\\\\x = \dfrac{162}{26} = \dfrac{81}{13} \rm \: units \approx 6.2 \: \rm units[/tex]

Step-by-step explanation:

Multiply the number outside the brackets to the numbers inside:

So,

9 * 9x = 81x

9 * 2y = 18y

9 x -6 = -54

So the simplified or equivalent expression is:

81x + 18y - 54

Answer:

Step-by-step explanation:

Let x represent the number of oxen. Then the number of ducks is 22-x and the number of legs is ...

  4x +2(22 -x) = 72

  2x +44 = 72 . . . . . . . simplify

  x +22 = 36 . . . . . . divide by 2

  x = 14 . . . . . . . . . subtract 22; the number of oxen

  22-x = 8 . . . . . the number of ducks

There are 8 ducks and 14 oxen in the barn.

Answer:

C. its velocity was 475 km/ minute northward.

Step-by-step explanation:

Its velocity was 475 km/ minute northward. Then the correct option is C.

The quantity which has magnitude, and direction, and follows the law of vector addition is called a vector.

A meteor moving 475 km per minute traveling in a south-to-north direction passed near Earth in 2013. Because the meteor was only 45 m wide and was 27,700 km above Earth's surface, it was not visible without the aid of a telescope.

The velocity is the vector quantity. So, the direction in the space will not change.

Its velocity was 475 km/ minute northward. Then the correct option is C.

Answer:

[tex]f(x)=-x(x+2)(x-1)^2[/tex]

Step-by-step explanation:

From inspection, the curve has 3 turning/stationary points, which suggests it is quartic function.  In factored form:  ax(x + b)(x + c)(x + d)

From inspection, there are 3 roots at: [tex]x = -2, x = 0, x = 1[/tex]

Therefore x, (x + 2) and (x - 1) will be factors.  

Whenever a turning/stationary point touches the x-axis, we conclude that a root is repeated at that point.  Therefore, from inspection, root x = 1 is a repeated root.  So  x, (x + 2) and (x - 1)² are factors.

The quartic curve is a "n" shape, which means the leading coefficient is negative.  We are told the leading coefficient is + or - 1. Therefore, it will be -1.

Therefore, an equation for the function in factored form is:

[tex]f(x)=-x(x+2)(x-1)^2[/tex]

Answer:

See below and attached graph.

Step-by-step explanation:

The slope-intercept form of a straight line equation is y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).

With a slope of -2, we can write:

y = -2x + b

To find b, enter the given point (-5,-3) and solve for b:

y = -2x + b

-3 = -2(-5) + b

-3 = 10 + b

b = -13

The equation becomes:  y = -2x -13
