When looking at the angle, the sides adjacent and hypotenuse are given. This means we use the cos function. Since we are solving for an angle, we inverse the cos.

In calculator, type: cos^-1(6/8)

Answer is A 41.4°

velikii [3]

Answer:

$y-6 = -\frac{1}{2} (x+1)$

Step-by-step explanation:

For this case we have two points given (-1,6) and (1,5)

And we want to complete the point slope equation of the line:

$y-6 = m(x-x_o)$

We need to find the slope and we can use the following formula:

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

And replacing the info we got:

$m= \frac{5-6}{1-(-1)}=-\frac{1}{2}$

And then the equation would be given by:

$y-6 = -\frac{1}{2} (x- (-1))$

And our final answer would be:

$y-6 = -\frac{1}{2} (x+1)$

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Vanyuwa [196]

Answer:

The integral diverges

Step-by-step explanation:

Consider the integral from 0 to infinity of

$xe^{4x}$

We can do this in parts

$\int {xe^{4x} } \, dx =\int {x} \, d(e^{4x})/4\\ = x/4 e^{4x}-e^{4x}/16$

When we substitute limits infinity we find that the values become infinity

Hence the integral diverges

The given improper integral diverges

Find the measure of angle b if angle a is 22 degrees and the whole angle is 300 degrees

Dima020 [189]

Answer:

$a = 278^{\circ}$

Step-by-step explanation:

Given

$b = 22^{\circ}$

$Whole\ Angle = 300^{\circ}$

Required

Find the measure of a

Since there is no diagram to support the question, we'll assume that:

$a + b = Whole\ Angle$

This gives:

$a + 22^{\circ} = 300^{\circ}$

Subtract 22 from both sides

$a + 22^{\circ}-22^{\circ} = 300^{\circ}-22^{\circ}$

$a = 300^{\circ}-22^{\circ}$

$a = 278^{\circ}$
