Given csc(A) = 60/16 and that angle A is in Quadrant I, find the exact value of sec A in simplest radical form using a rational

fiasKO [112]

Answer:

$\frac{15 \sqrt{209} }{209}$

Step-by-step explanation:

Objective: Understand and work with trig identies.

Recall multiple trig identies and manipulate them to get from cosecant to secant.

Given

$\csc(a) = \frac{60}{16}$

Apply reciprocal identity csc a = 1/sin a.

$\sin(a) = \frac{16}{60}$

Apply pythagorean identity to find cos a.

$( \frac{16}{60}) {}^{2} + \cos(x) {}^{2} = 1$

$\frac{256}{3600} + \cos(x) {}^{2} = 1$

$\cos(x) {}^{2} = \frac{3600}{3600} - \frac{256}{3600}$

We can simplify both expression

$\cos(x) {}^{2} = \frac{225}{225} - \frac{16}{225}$

$\cos(x) = \frac{ \sqrt{209} }{15}$

Cosine is positve on quadrant 1 so that cos(a)

Apply reciprocal identity sec a= 1/ cos a.

The answer is

$\sec(a) = \frac{15}{ \sqrt{209} }$

Rationalize the denominator.

$\frac{15}{ \sqrt{209} } \times \frac{ \sqrt{209} }{ \sqrt{209} } = \frac{15 \sqrt{209} }{209}$

1. Make sure to respond with complete sentences! Show all work please:)

Explanation:

The numerator of the rational exponent will be the product of the exponents inside and outside the radical: 5·7=35. The denominator of the rational exponent will be the index of the radical: 6. Then the equivalent expression is x^(35/6)

The probability a bus will be full is 65% which words or words best describes the likelihood the bus will be full?

allsm [11]

Due to the fact that the question states there is a 65% chance the bus will be full, that is a very high probability. Therefore, there is only a 35% chance it wont be full. Or you can say it in fractional form: 65/100 chance of it being full, and a 35/100 chance of it being less than full.<span />

A number decreased by 0.37 times the number is 12.6 Find that number.

Semenov [28]

Answer:

Answer below, however this question is worded weirdly

Step-by-step explanation:

x(x - 0.37 ) = 12.6

simplify the equation

x^2 - 0.37x = 12.6

x^2 - 0.37x - 12.6 = 0
