Answer:

1) Ben, 2) $\Delta = 2$ , 3) $\dot m = 2.7$ , 4) $\dot M = 2.9$

Step-by-step explanation:

1) Ben has a higher rate of memorization, since the coefficient of the second power is lesser than the one from Alice.

2) The number of words can be estimated by integrating the function:

Alice

$\Delta m = -0.003\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}$

$\Delta m = 27$

Ben

$\Delta M = -0.001\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}$

$\Delta M = 29$

$\Delta = \Delta M - \Delta m$

$\Delta = 2$

3) The average amount of words per minute is:

$\dot m = \frac{27}{10}$

$\dot m = 2.7$

4) The average amount of words per minute is:

$\dot M = \frac{29}{10}$

$\dot M = 2.9$

Answer:

8 points left and 7 points down

Step-by-step explanation:

Get the difference of one point on M and corresponding point on L, and find the difference of coordinates.

<u>Lets take top right points:</u>

(7, 9) and (-1, 2)

<u>The difference:</u>

-1 - 7 = -8 ⇒ 8 points left
2 - 9 = -7 ⇒ 7 points down

True or False: Given the illustration below, the value of y is 100º

sladkih [1.3K]

we are given

we know that

sum of all angles in any quadrilateral is 360

so, we can write it as

$y+120+85+53=360$

now, we can combine it

$y+258=360$

now, we can subtract both sides 258

$y+258-258=360-258$

$y=102$

so, this is FALSE..........Answer
