How to find cos(-19pi/6)

Answers

Use the unit circle.

-19pi/6 is the same as 3pi + pi/6
This means that it goes around the unit circle 3pi times and ends up at 7pi/6

So -19pi/6 is equivalent to 7pi/6.

Looking at the unit circle, cos(7pi/6) = -√3/2

Bryan is cooking cupcakes for a bake sale at his club. The recipe calls for 12 cups of flour. He has already put 3 cups of flour in the mixing bowl. How many more cups does he need to put in? Write an equation to represent this problem. Then solve.

Answers

Answer:

Bryan needs 9 cups more.

Step-by-step explanation:

Bryan is cooking cupcakes for a bake sale at his club. The recipe calls for 12 cups of flour.

Number of cups of flour, he already has = 3

Lets say he needs x cups more.

So, equation forms = $12=x+3$

=> $12-3=x$

x = 9

Hence, Bryan needs 9 cups more.

Answer:

9 cups

Step-by-step explanation:

12-3 = 9

Please help...The radius of the planet is 4100 miles. Find the distance d to the horizon that a person can see on a clear day from a height of 1298 feet above the planet. (hint: use the conversion 1 mile = 5280 ft) Round your answer to the nearest 10th, and don't forget to convert feet to miles.

Answers

First, we are going to convert 1298 feet to miles. Since we know that 1 mile = 5280 ft, we are going to multiply 1298 ft by $(1mi)/(5280ft)$ to do that:
$1298ft*(1mi)/(5280ft)= (59)/(240) mi$

Next, we are going to set up a right triangle using the radius of the Earth and the distance above the planet.
The hypotenuse of our triangle will be the radius of the Earth + the distance above the planet. One of the legs of our triangle will be the radius of the Earth, and the other leg, $d$ , will be the distance that a person will see on a clear day.
Using the Pythagorean theorem:
$d^2= ((984059)/(240) )^2-4100^2$
$d= \sqrt{((984059)/(240) )^2-4100^2}$
$d=44.9$ miles

We can conclude that the distance, $d$ , to the horizon that a person can see on a clear day from a height of 1298 feet above the planet is 44.9 miles.

Find the value of d that makes the equation true: d - 8 = 5.

d = 10
d = 11
d = 12
d = 13

Answers

To answer this, you need to get "d" on one side by itself. To do this, add 8 to both sides of the equation.

d- 8 + 8 = 5 + 8
-8 and +8 cancel out leaving:
d = 13

Your answer is d = 13
