The equation that relates the time, t, it takes to travel a given distance, d is d = rt

This is a scalar quantity and can be defined as  the magnitude of the rate of change of its position with time.

d = rt

where d is distance, r is speed or rate, t is time.

We can calculate the time by dividing the distance with the rate (speed).

t =  d/r

This is why it was chosen as the most appropriate choice.

The function is

The remainder when f(x) is divided by x−2 is 23

To find:

The value of k.

Solution:

According to the remainder theorem, if a polynomial P(x) is divided by (x-c), then the remainder is P(c).

It is given that, the remainder when f(x) is divided by x−2 is 23. By using the remainder or theorem, we get  

Put x=2, to find the value of f(2)

Using (i) and (ii), we get

Therefore, the value of k is 8.

Step-by-step explanation:

f(x) - 2x³ + kx - 4 and the remainder when f(x) is divided by x + 2 is -18.  then k is 15.

The remainder theorem states that when a polynomial p(x) is divided by (x - a), then the remainder = f(a)

f(x)=2x³ + kx - 4

x+2=0

x=-2

By the remainder theorem, the remainder when dividing by x-a is f(a)

f(-2)=2(-2)³+k(-2)-4

=-2(-8)-2k-4

=16-2k-4

The remainder is -18.

So, 16-2k-4=-18

12-2k=-18

-2k=-18-12

-2k=-30

k=15

Hence the value of k is 15.

Step-by-step explanation:

The total number ot turbans that Lisa's inventory should have 9 turbans in the next 18 hats when requested, under the condition that recently lent out a number of different hats. ski hats 4 berets 1 turban.

The evaluated probability of turbans in Lisa's inventory is 5/10 or 1/2. This projects that out of every 10 hats in Lisa's inventory, 5 are turbans.
To evaluate the expected number of turbans in the next 18 hats taken from Lisa's inventory, we can apply  the formula:
Expected number of turbans = Probability of turbans × Total number of hats requested
Staging the values
The turbans that are expected  
= (1/2) × 18
= 9

Answer:

(7 miles)/(50 minutes) = (x miles)/(75 minutes)

7/50 = x/75

7*75 = 50x

525 = 50x

50x = 525

x = 525/50

x = 10.5

make it a fraction

[tex]\frac{7}{50}= \frac{x}{75}[/tex]     (we cross multiply)

525=50x   (divide both sides by 50)

Answer:

[tex]y = - \frac{9}{8} x + 7[/tex]

Step-by-step explanation:

[tex]m = \frac{ - 2 - 7}{8 - 0} = \frac{ - 9}{8} [/tex]

Since this line passes through (0,7), then this point satisfies the equation of the line;

[tex]y = \frac{ - 9}{8} x + b[/tex]

[tex]7 = \frac{ - 9}{8} (0) + b[/tex]

[tex]7 = b[/tex]

[tex]b = 7[/tex]

Hey there!

We are given 2 points that the line passes through, so we can easily determine the slope of the line:

[tex]\bold{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]

[tex]\bold{\displaystyle\frac{-2-7}{8-0}=\frac{-9}{8} }[/tex]

So now we have the slope.

However, we also need to find the y-intercept (we are actually given the y-intercept, (0,7) or just 7)

Hence, the equation is

[tex]\boxed{\boxed{\bold{y=-\frac{9}{8} x+7}}}[/tex]

You can see this when you realize that both the sum of the remote angles and the exterior angle are supplementary to the third interior angle, ∠2. Angles supplementary to the same angle are congruent. That is, the sum of 29° and 65° is congruent to ∠1.

Answer:

  x = -15

Step-by-step explanation:

It appears the drawing is showing two representations for the distance LK. Of course, they both have the same value.

  10 = LK = x+25

Subtracting 25 from the equation, we have ...

  -15 = x

(This value of x makes KJ = (2(-15)+27) = -3, a nonsense value.)

_____

Alternate (more sensible) interpretation

If the bottom line is intended to represent LJ, then we have ...

  10 +(2x+27) = (x +25) . . . . LK +KJ = LJ

  x +37 = 25 . . . . subtract x

  x = -12 . . . . . . .  subtract 37

With this value of x, the length of KJ is 2(-12)+27 = 3, and the overall length LJ is (-12)+25 = 13. This is consistent: LK=10, KJ = 3, LJ = 13.

Through the given information in the question, the value of x could be 12.

The perimeter of a rectangle is the total distance around the outside of the rectangle. It is calculated by adding together the length of all four sides of the rectangle. If the length of the rectangle is denoted by 'l' and the width is denoted by 'w', then the formula for the perimeter (P) of the rectangle is:

P = 2l + 2w

Alternatively, the formula can also be written as:

P = 2(l + w)

The perimeter of a rectangle is given by the sum of the lengths of all four sides. Therefore, we can write:

AB + BC + CD + DA = 22

We know that AB = CD = 9 since they are opposite sides of the rectangle. We also know that DA = BC = x - 5, since they are the other two sides of the rectangle.

Substituting these values into the perimeter equation, we get:

9 + x - 5 + 9 + x - 5 = 22

Simplifying the equation, we get:

2x - 2 = 22

2x = 24

x = 12

Therefore, the value of x could be 12.
