Using the Pythagorean theorem, find the length of c if a = 14 * the square root of 3 and b = 34

ANEK [815]

If c is the hypotenuse, we have

$c=\sqrt{a^2+b^2}=\sqrt{(14\sqrt{3})^2+34^2}=\sqrt{588+1156}=\sqrt{1744}$

If instead b is the hypothenuse, you have

$c=\sqrt{b^2-a^2}=\sqrt{1156-588}=\sqrt{568}$

How do you divide scientific notation problems like this: 0.00053 ÷ 29?

Shtirlitz [24]

You got to remember
$\frac{x^m}{x^n}=x^{m+n}$

first write them in scienfitic notation
0.00053= $5.3*10^{-4}$
29= $2.9*10^1$

so
$\frac{0.00053}{29}=$
$\frac{(5.3)(10^{-4})}{(2.9)(10^1)}=$
$(\frac{5.3}{2.9})(\frac{10^{-4}}{10^1}=$
$(1.8275862068965517241379310344828)(10^{-4-1})=$
$(1.8275862068965517241379310344828)(10^{-5})=$
$1.8275862068965517241379310344828*10^{-5}$

that's the answer

Answer:

i. A∪B = (1324,1342,1423,1432,2314,2341,3214,3241,2413,1431,4213,4231)

ii. A¹ = (3124,3142,4123,4132,2314,2341,3214,3241,2413,2431,4213,4231)

Step-by-step explanation:

A union set is the collection of elements in two or more subsets. Here set A is equal to (1324,1342,1423,1432) and set B is equal to (2314,2341,3214,3241,4213,4231,3214,3241).

A∪B = (1324,1342,1423,1432,2314,2341,3214,3241,2413,1431,4213,4231)

ii. the complement of a set represent those elements in the universal set which are not in a given subset.

U = (1324,1342,3124,3142,1423,1432,4123,4132,2314,2341,3214,3241,2413,2431,4213,4231),

A¹ = (3124,3142,4123,4132,2314,2341,3214,3241,2413,2431,4213,4231).this represents elements in the universal set U which are not in the set of A.

Please help, last unit of algebra 2, thankyou!!!!!!!!!!!!

Answer:

$\cot \theta = \frac{8}{15} \\\\\sec \theta = \frac{17}{8} \\\\\csc \theta = \frac{17}{15}$

Step-by-step explanation:

$\huge \tan \theta = \frac{15}{8} ...(given) \\ \\ \huge \because \: \cot \theta = \frac{1}{ \tan \theta} \\ \\ \huge \therefore \: \cot \theta = \frac{1}{ \frac{18}{8} } \\ \\ \huge \therefore \: \cot \theta = \frac{8}{15} \\ \\ also \\ \huge \sec \theta = \frac{17}{8} \\$
