State whether the given measurements determine zero, one, or two triangles.. . C = 30°, a = 32, c = 16

Nat2105 [25]

Sin(A) / a = Sin(C)/c
Sin(A) = a * Sin(C)/c
Sin(A) = 32 * Sin(30)/16
Sin(A) = 32 * 0.03125
Sin(A) = 1

A = 90°

<span>By the law of sines, angle A must be 90 degrees. That makes side a the hypotenuse of a 30-60-90 triangle. There is only one triangle. The third side is 16</span>√<span>3, and the third angle 60</span>°<span>.</span>

Use a graphing calculator to solve the equation -2sin(theta)= 1.2 in the interval from 0 to 2pi.

elena-s [515]

Answer:

$\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64$

Step-by-step explanation:

As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:

$\theta=3.7\\\\and\\\\\theta=5.7$

So, it's useful to solve the equation too, in order to verify the result:

$-2sin(\theta)=1.2\\\\sin(\theta)=-\frac{3}{5}$

Taking the inverse sine of both sides:

$\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64$

Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:

$\theta\approx 3.785\\\\\theta \approx 5.64$

What is the slope of AC?

Inga [223]

Answer:

$\frac{b-d}{a-c}$

Step-by-step explanation:

Let $(x_1,y_1)=A(a,b)$ and $(x_2,y_2)=C(c,d)$ .

The slope of AC can be found using

$m=\frac{y_1-y_2}{x_1-x_2}$

Substitute the variables to get;

$m=\frac{b-d}{a-c}$

find the first 4 terms of the sequence defined by the explicit rule f(n)=7(n-1)-10. Is it an arithmetic sequence?

Nutka1998 [239]

This is an arithmetic sequence

f(1) = 7(0) -10 = -10

f(2) = 7(1) -10 = -3

f(3) = 7(2) -10 = 4

f(4) = 7(3) -10 = 11

Given that events "A" and "B" are independent, P(A)= 0.80 and P(A and B) = 0.24, what is P (B)?

Tanya [424]

Answer:

0.30

Step-by-step explanation:

They are independent, so:

P(A and B) = P(A) P(B)

0.24 = 0.80 P(B)

P(B) = 0.30
