Answer:
2√5
Step-by-step explanation:
Using the formula for calculating resultant
R = √Fx + Fy
\sum Fx = -2sin 45 + 4 cos 45
\sum Fx = 2cos45
\sum Fx = 2(1/√2)
\sum Fx = 2/√2
Similarly;
\sum Fy = 2 cos 45 + 4 sin45
\sum Fx = 2(1/√2) + 4(1/√2)
\sum Fx = 6/√2
Magnitude = √(2/√2)²+6/√2)²
Magnitude = √4/2 + 36/2
Magnitude = √2+18
Magnitude = √20
Magnitude = 2√5
Hence the magnitude of their sum is 2√5
Well what were given:
1 inch = 30 feet
The drawing of the building of this problem has the height of 1.25 inches and base of 0.75 inches.
Actual height:
1.25 inches * 30 feet/inch = 37.50 feet
Actual base:
0.75 inches * 30 feet/inch = 22.50 feet
So in this problem the answer would be "A" 22.50 Aka 22.5 For the building. Hope this helps you! (:
Answer: 37.778 degrees
Step-by-step explanation:
The third digit to the right of the decimal is thousandths. If the next digit to the right of that is 5 or more, add one to the thousandths. Otherwise leave it as is. Just drop everything to the right of the place you rounded to.
7 is greater than 5, so add 1 to the 7 in the thousandths place and get
37.778
Answer:
3 1/8 miles I think
Step-by-step explanation:
