Answer: 3/2

Step-by-step explanation:

Just take the length of 1 side, for example LP, and count the length in units.

LP = 8 units

Now, L’P’ = 12 units, so divide the length of L’P’ by LP to get the factor of dilation.

12/8 = 3/2

kondaur [170]

<em>Complete Question:</em>

<em>The function shown models the depth d (in inches) of snow on the ground during the first 9 hours of a snowstorm, where t is the time (in hours) after the snowstorm begins. </em>

<em> The -intercept means that there were[ ]inch(es) of snow on the ground at the start of the storm and the slope means that[ ]inch(es) of snow falls every hour during the storm. </em>

<em>Function: d(t)= 1/2t+6</em>

Answer:

$b = 6$

$m = \frac{1}{2}$

Step-by-step explanation:

Given

$d(t)= \frac{1}{2}t+6$

Required

Determine the y intercept and the slope

y-intercept:

$d(t)= \frac{1}{2}t+6$

A function has a format of:

$d(t) = mt + b$

Where b represent the y intercept:

By comparison of $d(t) = mt + b$ and $d(t)= \frac{1}{2}t+6$

$b = 6$

Slope:

A function has a format of:

$d(t) = mt + b$

Where m represent the slope

By comparison of $d(t) = mt + b$ and $d(t)= \frac{1}{2}t+6$

$m = \frac{1}{2}$

With a short time remaining in the day, a delivery driver has time to make deliveries at 7 locations among the 9 locations rema

kotegsom [21]

<h2>Answer:</h2>

The different possible routes are :

181440

<h2>Step-by-step explanation:</h2>

We are asked to find the number of different routes that are possible to choose 7 locations among the 9 locations remaining.

This means that we have to chose the locations and also we have to arrange them in different orders according to the different order of locations.

The method we have to use is a method of permutation.

When we have to chose and arrange r items out of a total of n items then the formula is given by:

$n_P_r=\dfrac{n!}{(n-r)!}$

Here we have: n=9

and r=7

Hence, the different possible routes are:

$9_P_7=\dfrac{9!}{(9-7)!}\\\\\\9_P_7=\dfrac{9!}{2!}\\\\\\9_P_7=181440$

Hence, the answer is:

181440

the rule for being the nth item in a certain sequence is n(n+1)/2. what is the 4th term in this sequence ? a.) 4b.)10c.)16d.)20

abruzzese [7]

The 4th term of the sequence can be determined as,

$\begin{gathered} a_n=\frac{n(n+1)}{2} \\ a_4=\frac{4(4+1)}{2} \\ a_4=10 \end{gathered}$

Thus, option (b) is correct.
