Answer: -1
Step-by-step explanation:
First change tan(315) to:
Then evaluate the sine and cosine function. What is the y component of 315 degrees? What is the x component of 315 degrees?
You are going to make a graph. The x-axis will represent age while the y-axis represents the amount of money spent on a night out. Graph the ordered pairs, making a scatter plot. Once you have all of the points on the graph, answer the question by saying something like "the older someone is, the less money they spend on a night out" but make sure it's accurate. (:
Answer
7.5 pounds
Step-by-step explanation:
Since adding x grams of salt will bring th percentage of the salt to 25
Hence. 10% of the 50 gram gives. 5 gram initial salt before it is added.
5+ x/ 50 * 100= 25/
5+x /50 = 0.25
5+x = 12.5
X= 12.5- 5
X= 7.5pounds
The answer to Cindyelias82 question is 5.65685425i
Square Root (-2)+Square Root(-18)=5.65685425i
Answer: I think it is 1572 sq feet
Step-by-step explanation:
Lxwxh
14x13x9=1638
Window is 4x4.5=18
Door 1 is8x3=24
Door 2 8x3=24
Since the doors and window are not included in what was painted you need to subtract those totals from the room.
So, 1638-18=1620
1620-48(two doors)=1572 sq feet
