Based on definition of unit circle and angle properties on Cartesian plane, we find the following results: A: π/5, B: 3π/7, C: 4π/3.

How to determine angles in a unit circle

Units circles are commonly used to understand angles and trigonometric functions in a simple way. Vectors in a unit circle are ordered pairs of polar form: (x, y) = (cos θ, sin θ).

To solve this problem, we must take these tips into account:

Angles in the first quadrant are within 0 < θ < π/2.Angles in the second quadrant are within π/2 < θ < π.Angles in the third quadrant are within π < θ < 3π/2.Angles in the fourth quadrant are within 3π/2 < θ < 2π.

Then, we have the following results: A: π/5, B: 3π/7, C: 4π/3.

Use the zero product property to find the solutions to the equation (x + 2) (x + 3) = 12
OX= -6 or x = 1
OX=-3 or x = -2
x= -1 or x = 6
Ox=2 or x=3

Answers

Answer:

x = -6 and x = 1

Step-by-step explanation:

Given the equation (x + 2) (x + 3) = 12

Equate to zero;

(x + 2) (x + 3) - 12 = 0

Expand

x^2+3x+2x+6-12 = 0

x^2+5x - 6 = 0

Factorize

x^2 + 6x - x - 6 = 0

x(x+6)-1(x+6) = 0

(x+6)(x-1) = 0

x+6 = 0 and x -1 = 0

x = -6 and x = 1

Hence the zeros are x = -6 and x = 1

What is the slope and y intercept?

Answers

Answer:

slope: 1/2 Y Intercept: 25 (I'm just guessing by the coordinates (60,25)

Step-by-step explanation:

Lets all remember rise over run to figure out slop and at coordinates (60, 25) we see that we go up 1 (rise) and go on the positive side 2 (run)

For the Y intercept (I'm really not sure about this answer) I figured it out by looking at the first point I saw (60, 25)

so I inferred that the y intercept is 25

You work for a city department which is hosting a 5 kilometer run. Your coworker measured the course and doing that it is only 4.75 kilometers long. He ask you to move the finish line forward 0.25 kilometers. Your tape measure is measured in feet and inches. What is the distance he asked you to move in line in the nearest foot?

Answers

Answer:

820 feet

Step-by-step explanation:

We can use the rule of three in this scenario since this is a ratio problem with one unknown. To do this we simply multiply the diagonal values and divide by the final value. We know that there are a total of 3280.84 ft in a single kilometer, therefore...

1 km == 3280.84 ft

0.25 == x

(0.25 * 3280.84) / 1 = 820.21

Now we can see that there are 820.21 ft in the 0.25 kilometers. If we round this to the nearest foot we would round down to a total of 820 feet.

Length = 40 cm

Width = 20 cm

Height = 35 cm

Volume of the rectangular prism = Length × Width × Height

= 40 × 20 × 35

= 28000 cm³

Since, 1 cm³ = 1 mL

Therefore, 28000 cm³ = 28000 mL

Since, 1000 mL = 1 L

28000 mL = 28 L

Therefore, to fill this jar 28 L of orange juice will be required.

Miles and Lucy decide to sell lemonade to earn some money. They buy pitchers, ice, and mix for a cost of $13.50. The mix makes 8 quarts of lemonade. They decide to sell one cup of lemonade for $0.75. If they sell all 8 quarts, how much revenue will they make and will they make enough to earn $12 each? (4c=1q)

Answers

Answer:

Altogether they made $24 which is enough to earn $12 each

Step-by-step explanation:

Important information:

1 cup: $0.75

4 cups = 1 quart

8 quarts of lemonade altogether

If we are looking to solve for the revenue earned based on quarts, we must first solve for how much money they make on 1 quart

Since 1 cup sells for $0.75 and 4 cups makes up a quart, we must multiply

0.75 × 4 = 3

They make $3 per 1 quart

We are looking for the amount for 8 quarts though, not just 1. Again we must multiply

3 × 8 = 24

They will make $24 if they sell all 8 quarts

The questions ask if they will each earn $12

Since there are two of them, Miles and Lucy, we must divide revenue earned by 2, the number of people

24 ÷ 2 = 12

$12

In the summer of 1781, James Forten signed onto the privateer Royal Louis, commanded by Stephen Decatur, Sr.The colonies had few ships of their own to fight against the powerful British navy and issued letters of marquetoprivate parties. These allowed theships, under the flag of the United States, to attack British ships and to profit from the sale of any vessel captured.The Royal Louis sailed out ofPhiladelphia in August and was quickly engaged by the British vessel Active, a heavy armed brig sent from England to protect its trade ships. The Royal Louiss guns were loaded with gunpowder that was tamped down by an assistant gunner. Then the cannonball was put into the barrel and pushed against the powder. Then thepowder would be ignited. Thepowder had to be kept below decks in case of a hit by an enemy ship. page 426; ortens job was to carry thegunpowder from below to the guns.Up and down the stairs he raced with the powder as shots from the British ship whistled overhead. There were large holes in the sails and men screaming as they were hit with grapeshot that splintered the sides of the ship. The smell of gunpowder filled the air as Captain Decatur turned his ship to keep his broadside guns trained on theActive. Sailors all about Forten were falling, some dying even as others cried for more powder. Again he went belowdecks, knowing that if a shot ripped through to the powder kegs, or if any of the burning planks fell down into the hold, he would be killed instantly in the explosion. Up he came again with as much powder as he could carry.After what must have seemed forever with the two ships tacking about each other like angry cats, the Active lowered its flag. It had surrendered! Decatur brought his ship into Philadelphia, its guns still trained on the limping Active. The crowd on the dock cheered wildly as they recognized the American flag on the Royal Louis.. On board the victorious ship James Forten had mixed feelings as he saw so many of his comrades wounded, some mortally. The Royal Louis turned its prisoners over to military authorities. On the twenty-seventh of September, the Activewas sold; the proceeds were split among the owners of the Royal Louis and the crew. The sailors with the worst wounds were sent off to be cared for. The others, their own wounds treated, were soon about thebusiness of repairing the ship. Forten must have been excited. Once the fear of the battle had subsided and the wounded were taken off, it was easy to think about the dangerous encounter in terms of adventure. And they had won.
