Answer: First option.
Step-by-step explanation:
You need to remember the following Trigonometric Identity:
In this case, you can identify in the figure that:
Then you must substitute these values into :
Finally, you need to solve for "x" in order to find its value. This is:
Rounding the result to the nearest tenth, you get:
On a graph, go up 7 units and to the right 2 units from the origin
Robert Morris, generally considered the financier of the Revolution, donated ships from his fleet of tobacco-trading vessels and turned to privateering. Raiding British convoys, he became the richest man in America. He personally signed 6,000 notes to pay off Washington's troops when the war ended.
Answer:
w = 11.25
Step-by-step explanation:
To solve this problem, we are going to move all of the terms containing the variable w to the left side of the equation and all of the constant terms (ones with numbers only) to the right side of the equation.
w - 24 = -3w + 21
To do this, we should first add 24 to both sides of the equation.
w - 24 + 24 = -3w +21 + 24
If we simplify, we get:
w = -3w + 45
Next, we should add 3w to both sides of the equation.
w + 3w = -3w + 3w + 45
4w = 45
Finally, we can divide both sides by 4.
4w/4 = 45/4
w = 11.25

Answer:
x = ±10
Step-by-step explanation:
4x² - 400 = 0
Add 400 to both sides
4x² = 400
Divide both sides by 4
x² = 100
Take the square root of both sides
x = ±10
