Question: Give the perimeter of the figure... a regular 17-gon with side length 4.5cm.

1 answer:

Define perimeter first.

It's the total length of the outline(or outside) of a shape.

So... 17-gon means 17 sides, each side with length 4.5.

All you have to do? Add 4.5 by itself 17 times! Or, just multiply 4.5 by 17.

4.5 x 17 = 76.5

Perimeter: 76.5

2. What does y equal? *<br> y+3/4 = 6

kakasveta [241]

Answer:

3rd option

Step-by-step explanation:

Given

y + $\frac{3}{4}$ = 6 ( multiply through by 4 to clear the fraction

4y + 3 = 24 ( subtract 3 from both sides )

4y = 21 ( divide both sides by 4 )

y = $\frac{21}{4}$ = 5 $\frac{1}{4}$

Two forces act on an object. The first Force has a magnitude of 400 Newtons and acts at an angle of 30 degrees as measured from

Sedaia [141]

ANSWER

Option D is correct

EXPLANATION

We resolve the forces into component forms.

$F_1 = 400 \cos(30) i + 400 \sin(30) j$

$F_1 = 200 \sqrt{3} i +200j$

Also the second is resolved to obtain,

$F_2= 280 \cos(135) i + 280 \sin(135) j.$

$F_2= - 140 \sqrt{2} i + 140 \sqrt{2} j$

To find the resultant vector, V, We add the corresponding components of the two forces to get:

$V=F_1+F_2$

$\implies \: V = (200 \sqrt{3} - 140 \sqrt{2} )i + (200 + 140 \sqrt{2})j$

The correct answer is D.
