Given that csc = -13/5 for π < t < (3 π)/2, use an appropriate identity to find the value of cot(t). What is cot(t)?

Since cosecant is 1/sin(t), set up a proportionality of -13/5 = 1/sin(t) then you get t = arcsin(-5/13). This means cotangent of t would be 1/tan(arcsin(-5/13)). Which is -2.4 or -12/5. But since π < t < (3 π)/2, cot(t) should be positive. Meaning that it is 12/5 or 2.4… right?

b mark me branliest thx

step-by-step explanation:

there is no graph so i cant sorry

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
