9 because if you add 6x and 4x it makes 10x. if youre finding a 90 degree angle then it has to equal 90. 10 x 9 = 90.

a. In the general education course requirement at a college, a student needs to choose one each from social sciences, humanities
Elenna [48]

Using the Fundamental Counting Theorem, there are 240 ways to choose general education courses from these 4 areas.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

Considering the number of options for each course, the parameters are given as follows:

n_1 = 5, n_2 = 4, n_3 = 4, n_4 = 3.

Hence the number of ways is given by:

N = 5 x 4 x 4 x 3 = 240.

The volume V of a right‑circular cylinder is computed using the values d = 3.1 m for the diameter and h = 6.6 m for the height.
pantera1 [17]

Answer:

6%

Step-by-step explanation:

A function f(x) can by approximated at and around a point, say x = a by,

f(x) = f(a) + f'(a)(x-a)

where,  f'(x)=\frac{df}{dx}

Here, volume V is a function of radius r and height h. In the 2 dimensional case, we have to take the partial derivatives.

Given,

V=\pi r^2h

or, dV=\frac{\partial V }{\partial r}dr+ \frac{\partial V }{\partial h}dh

at r = 1.55 m and h = 6.6 m

dr=0.02\times1.55m=0.031m

dh=0.02\times6.6m=0.132m

\frac{\partial V }{\partial r}=2\pi r h=2\pi \times 1.55\times 6.6=64.277

\frac{\partial V }{\partial h}=\pi r^2=7.5477

Therefore, dV=(64.277\times.031)+(7.5477\times0.132)=2.9889m

Also, V=\pi r^2h=49.8147m

Hence, maximum error is given by,

R=\frac{2.9889}{49.8147} \times 100

= 6%
