Answer:

1. $\frac{\sqrt{13} }{3}$

2. 3.2362

3. $\frac{60}{11}$

Step-by-step explanation:

Cot is the trigonometric ratio defined by "adjacent" over "opposite". So, adjacent = 2 and opposite = 3.

By pythagorean theorem, we have the "hypotenuse" as $\sqrt{2^2+3^2}=\sqrt{13}$

Csc is defined as the trig ratio "hypotenuse" over "opposite". We know the sides, so Csc $\theta$ = $\frac{\sqrt{13} }{3}$

First answer choice is right.

By definition, Csc $\theta$ is the inverse of Sine $\theta$ . If given the value of sin theta, to find value of csc theta, we take the reciprocal of it. Hence:

$Csc\theta=\frac{1}{0.3090}\\=3.2362$

Third answer choice is right.

By definition tan and cot are inverse of each other. So the value of tan is the reciprocal of the value of cot. We can simply "flip" the value of tan theta to get the value of cot theta. Hence:

$Cot\theta=\frac{60}{11}$

Third answer is right.

How to find two different ways to find the new value after the original value is increased by 30%

maria [59]

The new value after the original value is increased by 30% is 1.3 times the original value.

<h3>Percentage</h3>

Percentage is used to express a fraction number or decimal in fraction of hundred. It is given by:

Percentage = [(new value - original value) / original value] * 100%

Let x represent the new value and y represent the original value, hence:

30% = [(x - y)/y] * 100%

0.3 = (x - y)/y

x - y = 0.3y

x = 1.3y

The new value after the original value is increased by 30% is 1.3 times the original value.

What are the solutions of the quadratic equation (x + 3)2 = 49? x = –2 and x = –16 x = 2 and x = x = 4 and x = –10 x = 40 and x

steposvetlana [31]

Im gonna assume you are solving for x, the equation (x + 3)2 = 49 x is equal to 21.5 or 21 and 1/2. however the rest aren’t equations they’re just x = number and there isn’t much to do with that
