Answer:

No not enough meat

Step-by-step explanation:

To make 10 burgers requires

10 × $\frac{1}{4}$ = $\frac{10}{4}$ = 2 $\frac{2}{4}$ = 2 $\frac{4}{8}$

Dao only has 2 $\frac{3}{8}$ ← not enough

In a memory experiment, Alice is able to memorize words at a rate given by m '(t)= - 0.009t^2 + 0.6t. In the same memory exper

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:

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

$\dot M = 2.9$
