Given a triangle with b = 7 c = 3 and A = 37 degrees, what is the length of a?

1 answer:

7 0

Using cosine rule a^2 = b^2 + c^2 - 2bc cos A = 7^2 + 3^2 - (2 x 7 x 3) cos 37 = 49 + 9 - 42cos 37 = 58 - 33.54 = 24.46
a = sqrt(24.46) ≈ 5

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

White raven [17]

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:

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

$\dot M = 2.9$
