Allushta [10]3 years ago
6 0

Answer:

The answer to your question is below

Step-by-step explanation:

Process

1.- Find to points of each line

2.- Substitute the values of the points in the formula

                               (m = \frac{y2 - y1}{x2 - x1}

3.- Simplify to find the slope

Line A

                                (m = \frac{3 - 1}{2 - 1}

                                m = \frac{2}{1}

                                       m = 1

Line B

                                (m = \frac{3 - 3}{2 - 1}

                                m = \frac{0}{1}

                                       m = 0

Line C

                               (m = \frac{2 - 0}{-2 - 4}

                               m = \frac{2}{-6}

                               m = - \frac{1}{3}

Line D

                              (m = \frac{3 - 1}{-1 - 2}

                              m = \frac{2}{-3}

Find sin theta if theta is an angle in standard position and the point with coordinates (3, -4) lies on the terminal side of an
alisha [4.7K]

Answer:

\sin \theta=-\frac{4}{5}

Step-by-step explanation:

Given:

Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).

So, the 'x' value is 3 and 'y' value id -4.

Using Pythagoras Theorem, we find the hypotenuse.

Hypotenuse = \sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5

Now, using the sine ratio for the angle, we have

\sin \theta=\frac{Opposite}{Hypotenuse}\\\sin \theta=\frac{-4}{5}\\\sin \theta=-\frac{4}{5}

Therefore, the value of \sin \theta is -\frac{4}{5}.

The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,

Alik [6]

Answer:

After 3 seconds

Step-by-step explanation:

Given

h(t) = -16t^2 + 96t

Required

Seconds to attain maximum height

The maximum of a quadratic function y = ax^2 + bx + c is calculated using:

x = -\frac{b}{2a}

So, we have:

t = -\frac{b}{2a}

Where:

a = -16 and b = 96

So:

t = -\frac{96}{2 * -16}

t = -\frac{96}{-32}

Cancel out negatives

t = \frac{96}{32}

t = 3

Evaluate each expression (image provided). A.) 5 B.) 7 C.) 4 D.) 6
Mkey [24]

<h3>The answer is option A.</h3>

Step-by-step explanation:

log_{3}(243)

Can be written as

log_{3}( {3}^{5} )

Which is the same as

5 log_{3}(3)

But

log_{3}(3)  = 1

So we have

5(1) = 5

Hope this helps you
