the answer is A because if it needs to be over 60 the last two don't make sense and since for every question he makes 2 points how ever many points he makes is x and he need to multiply that by 2.

(a) Find the differential dy.

Step2247 [10]

a. Practically speaking, you compute the differential in much the same way you compute a derivative via implicit differentiation, but you omit the variable with respect to which you are differentiating.

$y=\cos x\implies\boxed{\mathrm dy=-\sin x\,\mathrm dx}$

Aside: Compare this to what happens when you differentiate both sides with respect to some other independent parameter, say $t$ :

$\dfrac{\mathrm dy}{\mathrm dt}=-\sin x\dfrac{\mathrm dx}{\mathrm dt}$

b. This is just a matter of plugging in $x=\dfrac\pi3$ and $\mathrm dx=0.1$ .

$\boxed{\mathrm dy\approx-0.087}$

given the function f(x) = 2^x, find the value of f−1(32). (1 point) f−1(32) = 0 f−1(32) = 1 f−1(32) = 5 f−1(32) = 16

Answer:

5

Step-by-step explanation:

The inverse of $f(x)=2^x$ is $g(x)=\log_2(x)$ .

$g(32)=\log_2(32)$

$\log_2(32)=5$ since $2^5=32$ .

$g(32)=\log_2(32)=5$

Note: In general, the inverse of $f(x)=a^x$ is $g(x)=\log_a(x)$ .
