Calculate the length of the diagonal of a rectangle whose sides measure : (a) 12 meters and 48 meters (b) 11 centimetres and 60

Serggg [28]

When solving this problem, you need to imagine the diagonal line through the rectangle. This makes two triangles which you can use the pythagorean theorem for. 12 squares plus 48 squared equals 2,448. Find the square root of that at it will be your answer (I don’t have the time to figure it out). 11 squared plus 60 squared is 3,712. Square root tbd... add the label and you’re finished!

Which expressions are equivalent to -3x+6v+7x14?

Greeley [361]

Between the 4 and the 7 is it a multiplication or an X?

If the multiplication sign, this is the solution

$- 3x + 6v + 7 \times 14 \\ = 6v - 3x + 98$

The pointer of the vibration measuring instrument is observed to move between the 0.1 and0.3 marks on the vertical scale, when s

Norma-Jean [14]

Answer:

Step-by-step explanation:

Given points moves b/w 0.1 of 0.3 marks Hence amplitude is 0.2

Also , frequency (w) = 100 rad/s.

Natural frequency (wn) = √K/m

K = 20 N/mm x 1000mm/1m = 20000N/M

W = 1000mm/1m = 20,000N/M

FormulaX = FolK/1 - (w/wn)²

0.2 = b/20000/1 - (100/50)²

Given forcing frequency was doubled, W1 = 2 x 100=200rad/s

X1 =b/20,000/1 - (200/20)²

0.2/11 = 1 - (200/50)²/1 - (100/50)² = 0.2/11 = -15^5– 3

X1 = 0.04

The results of a survey of 43 students and the foreign language they are studying are shown in the two-way frequency table.

babunello [35]

Since 5 out of 43 people take chinese, it's 5/43 which is the same as 0.116 which means 11,6%

I hope this was helpful! Tell me if it's unclear!
